10 Early Signs of Glaucoma You Should Never Ignore
Glaucoma is often called the “Silent Thief of Sight” because it can slowly and silently damage your vision without any warning. By the time most people notice changes, the damage is already irreversible. However, your eyes might give subtle clues early on. Recognizing these signs and getting regular eye check-ups can protect you from permanent vision loss.
Here are 10 early signs of glaucoma that you should never ignore:
1. Gradual Loss of Side (Peripheral) Vision
One of the earliest signs of glaucoma is the slow reduction of your side vision. You may not realize it until you start bumping into objects or feel like you’re looking through a tunnel. Peripheral vision loss often goes unnoticed because your brain tries to compensate.
2. Frequent Changes in Glasses Prescription
Are you visiting your optician too often for a stronger prescription? While changing power is common, unusually frequent changes can signal underlying issues like glaucoma. The optic nerve damage affects how light focuses in your eyes, leading to shifting vision.
3. Blurred Vision, Especially in Low Light
If you’re experiencing blurry vision that gets worse in dimly lit environments, it might not just be eye strain. Glaucoma affects your eye’s ability to adjust to different lighting conditions, making it difficult to see clearly in the dark.
4. Seeing Halos Around Lights
Halos—colored rings around light sources, especially at night—can be an early symptom of glaucoma. This happens because increased eye pressure affects the cornea, leading to diffraction of light entering the eye.
5. Eye Pain or Pressure Sensation
Though most types of glaucoma are painless, Angle-Closure Glaucoma can cause sudden, severe eye pain or a feeling of pressure inside the eye. This is a medical emergency and needs immediate treatment to prevent permanent vision loss.
6. Redness in the Eye
Persistent redness in one or both eyes, without any clear cause like infection or injury, could be an early warning sign of rising intraocular pressure (IOP). Don’t ignore this symptom, especially if it’s accompanied by discomfort or visual disturbances.
7. Headaches, Especially Around the Eyes
Occasional headaches are common, but if you experience frequent headaches focused around the eye region, it could be due to fluctuating eye pressure—a potential indicator of glaucoma.
8. Difficulty Adjusting to Dark Rooms
Have you noticed it takes longer for your eyes to adjust when you move from a bright area into a dark room? This could be an early effect of glaucoma affecting your optic nerve function and pupil response.
9. Nausea or Vomiting (in Acute Cases)
In cases of acute angle-closure glaucoma, the rise in eye pressure can be so rapid and severe that it leads to systemic symptoms like nausea and vomiting, often mistaken for gastrointestinal issues.
10. Tunnel Vision in Advanced Stages
Though this is a sign of advanced glaucoma, it’s essential to recognize. Vision may narrow drastically, making you feel like you’re looking through a small tube. This stage indicates significant optic nerve damage, and immediate intervention is necessary to preserve remaining vision.
Why Early Detection is Crucial
Glaucoma damage is irreversible, but progression can be halted if caught early. A comprehensive eye exam—beyond just checking for glasses power—is the only way to detect glaucoma in its early stages.
Vision & Beyond Tip:

Are You at Risk? Understanding Glaucoma Risk Factors
Glaucoma is one of the leading causes of irreversible blindness worldwide. What makes it particularly dangerous is its silent progression—most people don’t realize they have it until significant vision loss has occurred. But did you know that certain risk factors can increase your chances of developing glaucoma?
Being aware of these risk factors and getting regular eye check-ups is your first line of defense.
What is Glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, usually due to increased pressure inside the eye (intraocular pressure or IOP). This damage can lead to gradual, irreversible vision loss if not detected and treated early.
Who is at Risk? Key Glaucoma Risk Factors
1. Age Above 40 Years
Glaucoma can occur at any age, but the risk increases significantly after the age of 40. The older you get, the higher the chances of optic nerve damage due to age-related changes in eye pressure regulation.
2. Family History of Glaucoma
Glaucoma often runs in families. If you have a parent, sibling, or grandparent with glaucoma, your risk increases by 4 to 9 times. Genetic factors play a crucial role in how your eyes handle pressure and fluid drainage.
3. Elevated Intraocular Pressure (IOP)
High eye pressure is one of the strongest risk factors for glaucoma. However, not everyone with high IOP will develop glaucoma, and some people with normal IOP can still get glaucoma (known as Normal-Tension Glaucoma).
4. Thin Corneas
The thickness of your cornea (the clear front surface of the eye) affects how your eye pressure is measured and regulated. People with thin corneas are at a higher risk of optic nerve damage, even if their measured IOP appears normal.
5. Diabetes and High Blood Pressure (Hypertension)
Chronic conditions like diabetes and hypertension affect blood circulation to the optic nerve, making it more vulnerable to damage. Diabetics are also more prone to developing secondary glaucoma due to changes in eye fluid dynamics.
6. Long-Term Steroid Use
Prolonged use of steroid medications—whether eye drops, inhalers, oral tablets, or skin creams—can increase intraocular pressure and lead to a type of glaucoma known as Steroid-Induced Glaucoma.
7. History of Eye Injuries or Eye Surgeries
A previous eye injury can cause long-term changes in the drainage angle of the eye, leading to secondary glaucoma. Similarly, certain eye surgeries can alter fluid outflow pathways, increasing glaucoma risk.
8. Ethnicity
Certain ethnic groups have a higher predisposition to glaucoma:
● African and Afro-Caribbean descent: Higher risk of developing aggressive forms of glaucoma at a younger age.
● Asian descent: More prone to Angle-Closure Glaucoma.
● Hispanics/Latinos: Increased risk after age 60.
9. Severe Myopia (Nearsightedness)
High myopia causes stretching of the eye’s structures, including the optic nerve, making it more susceptible to glaucomatous damage.
10. Obstructive Sleep Apnea (OSA)
Studies suggest a strong link between OSA and Normal-Tension Glaucoma. Repeated oxygen deprivation during sleep affects optic nerve perfusion, increasing glaucoma risk.
Should You Be Worried If You Have These Risk Factors?
Having one or more risk factors doesn’t mean you will definitely develop glaucoma. However, it does mean you should:
● Get a comprehensive eye exam every year (or as advised by your ophthalmologist).
● Monitor your eye pressure and optic nerve health regularly.
● Be aware of subtle vision changes.
● Maintain good systemic health (control diabetes, hypertension, cholesterol).
Take-Home Message: Prevention Starts with Awareness
Glaucoma doesn’t announce itself until it’s too late. But knowing your personal risk can help you take proactive steps to safeguard your vision. Regular screenings, especially after the age of 40 or if you have risk factors, can detect glaucoma early when treatment is most effective.
Vision & Beyond Tip:
“Your family history, age, and health conditions are telling you a story. Listen to them—get your eyes checked for glaucoma before it whispers trouble.”

Can Glaucoma Be Prevented? Steps to Protect Your Vision
Glaucoma is often called the “silent thief of sight” because it causes slow, painless vision loss that can go unnoticed until significant damage has occurred. While glaucoma cannot be prevented in the traditional sense, early detection and proactive management can effectively prevent vision loss.
So, can you prevent glaucoma? You can’t always prevent the disease itself, but you CAN prevent it from stealing your sight.
Here’s how you can protect your vision from glaucoma.
Understanding Glaucoma Prevention
Glaucoma is influenced by several factors:
- Age and genetics (non-modifiable)
- Eye pressure, blood flow to the optic nerve, and systemic health (modifiable with treatment and lifestyle)
While you can’t change your age or family history, you can control modifiable risk factors and detect glaucoma early before vision loss occurs.
Steps to Protect Your Vision from Glaucoma
1. Regular Comprehensive Eye Exams
The most effective “prevention” is early diagnosis.
- After age 40: Schedule a detailed glaucoma screening every 1-2 years.
- If you have a family history of glaucoma, diabetes, or other risk factors, start even earlier.
- Screenings should include:
- Intraocular Pressure (IOP) measurement
- Optic nerve examination
- Visual field test
- OCT nerve fiber analysis
- Gonioscopy for drainage angle assessment
2. Know Your Risk Factors
Be aware of personal factors that may increase your risk:
- Family history of glaucoma
- Age above 40
- High eye pressure
- Thin corneas
- Diabetes or hypertension
- High myopia (nearsightedness)
- Steroid use
- History of eye injury
Understanding these risks can motivate timely check-ups and monitoring.
3. Manage Systemic Health Conditions
Conditions like diabetes, high blood pressure, and high cholesterol can affect optic nerve health.
- Maintain strict control of blood sugar and BP levels.
- Quit smoking to improve blood circulation.
- Exercise moderately to boost vascular health.
4. Protect Your Eyes from Trauma
Eye injuries can lead to secondary glaucoma.
- Wear protective eyewear during sports or hazardous work.
- Seek immediate care if you sustain an eye injury.
5. Be Cautious with Steroid Use
Long-term use of steroid eye drops, oral medications, or skin creams can increase eye pressure.
- Use steroids only under medical supervision.
- If long-term use is necessary, ensure regular eye pressure monitoring.
6. Maintain a Healthy Lifestyle
While lifestyle alone can’t prevent glaucoma, it supports overall eye health.
- Eat a balanced, antioxidant-rich diet (leafy greens, berries, omega-3s).
- Stay hydrated—sip water gradually throughout the day.
- Limit excessive caffeine intake, which may cause short-term eye pressure spikes.
- Avoid smoking, which compromises optic nerve blood flow.
7. Eye Pressure Management in High-Risk Individuals
For those identified with ocular hypertension (high eye pressure without nerve damage), preventive treatment with eye drops may be started to delay or prevent glaucoma onset.
8. Be Alert to Subtle Visual Changes
Glaucoma often progresses silently, but early signs can include:
- Blurred peripheral (side) vision
- Difficulty adjusting to low light
- Increased glare sensitivity
Don’t ignore these signs—consult your eye doctor promptly.
Take-Home Message
While you may not be able to prevent glaucoma from developing, you absolutely can prevent it from taking your vision. Regular eye exams, risk factor awareness, healthy lifestyle choices, and prompt treatment are your best weapons against glaucoma-related blindness.
At Vision & Beyond, we believe prevention is not about waiting for symptoms—it’s about staying one step ahead with proactive care.
Vision & Beyond Tip:
“You can’t feel glaucoma in its early stages—but you can find it. Prevent vision loss by making regular eye exams a lifelong habit.”

Coping with Vision Loss in Advanced Glaucoma – Supportive Strategies for Daily Living
Glaucoma is a progressive condition that, if left undiagnosed or uncontrolled, can lead to permanent vision loss. While early detection and treatment can halt its progression, some patients may already be in advanced stages with significant vision impairment by the time it’s diagnosed.
But vision loss doesn’t have to mean losing independence. With the right strategies, support systems, and assistive technologies, patients with advanced glaucoma can continue to lead fulfilling and active lives.
Understanding Vision Loss in Advanced Glaucoma
In glaucoma, vision loss typically starts with the peripheral (side) vision and progresses inward. This can lead to:
- Tunnel vision (narrow field of vision)
- Difficulty in low-light environments
- Trouble with contrast sensitivity
- Glare sensitivity
Central vision may remain unaffected until late stages, but mobility, depth perception, and daily tasks can become challenging.
Strategies to Cope with Glaucoma-Related Vision Loss
1. Optimize Home Lighting
- Ensure bright, even lighting in all rooms.
- Use task lighting for activities like reading, cooking, and sewing.
- Install motion-sensor lights in hallways and bathrooms.

Glaucoma Follow-Up Care: Why Regular Monitoring is Crucial
A diagnosis of glaucoma is not a one-time event—it’s a lifelong journey of monitoring and management. While treatments like eye drops, lasers, or surgery help lower intraocular pressure (IOP), the disease requires ongoing follow-up to ensure it stays under control.
Glaucoma can silently progress despite treatment, which is why regular follow-up care is crucial to protect your vision.
Why Is Follow-Up So Important in Glaucoma?
1. Glaucoma is a Progressive Disease
- It doesn’t stop after starting treatment.
- Vision loss may continue if the disease progresses silently in the background.
- Regular monitoring ensures timely adjustments in treatment to halt progression.
2. Intraocular Pressure (IOP) Can Fluctuate
- IOP levels can change due to stress, medication compliance, systemic health, or even seasonal changes.
- Regular check-ups help track these fluctuations and maintain pressure at a safe target level.
3. Treatment May Need Adjustments Over Time
- Eye drops may lose effectiveness or cause side effects.
- Additional medications, laser procedures, or surgeries might become necessary.
- Follow-up visits help assess how well your current treatment plan is working.
4. Structural and Functional Damage Can Be Subtle
- Optic nerve damage and visual field loss can progress without noticeable symptoms.
- Advanced imaging (OCT) and visual field tests can catch early signs of progression before you notice any vision change.
5. Post-Surgery Monitoring is Vital
- If you’ve undergone glaucoma surgery, the success of the procedure needs regular evaluation.
- Surgical sites (like filtering blebs or implanted stents) need monitoring for function and potential complications.
How Often Should You Follow Up?
Disease Stage — Follow-Up Frequency
- Suspected Glaucoma / Ocular Hypertension — Every 6-12 months
- Mild Glaucoma (Stable) — Every 4-6 months
- Moderate Glaucoma — Every 3-4 months
- Advanced / Unstable Glaucoma — Every 1-2 months or as advised
- Post-Surgery — Weekly initially, then monthly
Your ophthalmologist will personalize your follow-up schedule based on your condition’s stability and progression risk.
What Happens During a Glaucoma Follow-Up Visit?
A typical follow-up visit includes:
- Intraocular Pressure Measurement (Tonometry)
- Optic Nerve Head Examination (via Slit Lamp)
- Visual Field Test (Perimetry) – Periodically
- Optical Coherence Tomography (OCT) Imaging
- Assessment of Medication Compliance and Side Effects
- Evaluation of Surgical Sites (if applicable)
Tips to Make the Most of Your Follow-Up Visits
- Keep a log of any new symptoms or changes in vision.
- Carry your current medication list.
- Be honest about medication adherence.
- Ask questions and clarify doubts about your treatment plan.
- Bring a family member if you need help understanding instructions.
What Happens if You Skip Follow-Up Visits?
- Unnoticed progression of optic nerve damage.
- Missed opportunity to adjust treatment plans in time.
- Increased risk of irreversible vision loss.

Glaucoma: The Silent Thief of Sight – Symptoms, Risks & Treatments You Should Know
Glaucoma is a group of eye diseases that slowly damage the optic nerve—the vital connection between your eye and brain—leading to gradual vision loss. Often called the “Silent Thief of Sight,” glaucoma can progress without obvious symptoms until significant damage has occurred. Early diagnosis and timely treatment are key to preserving vision.
How Does Glaucoma Affect the Eye?
Inside your eye, there’s a clear fluid called aqueous humor that maintains eye pressure and nourishes internal structures. This fluid drains through a mesh-like channel. When this drainage is blocked or inefficient, fluid builds up, increasing Intraocular Pressure (IOP). Over time, elevated IOP damages the optic nerve fibers, leading to irreversible vision loss.
Types of Glaucoma
1. Primary Open-Angle Glaucoma (POAG):
- The most common type.
- Slow clogging of drainage canals.
- No symptoms in early stages.
- Peripheral (side) vision is affected first.
2. Angle-Closure Glaucoma (ACG):
- Less common but more severe.
- The drainage angle closes suddenly.
- Can cause sudden eye pain, headache, blurred vision, halos around lights, and nausea.
- Requires immediate medical attention.
3. Normal-Tension Glaucoma:
- Optic nerve damage occurs despite normal eye pressure.
- Suspected to be due to poor blood flow to the optic nerve.
4. Congenital Glaucoma:
- Present at birth.
- Signs include cloudy cornea, excessive tearing, and sensitivity to light.
5. Secondary Glaucoma:
- Caused by other eye diseases, injuries, or medications (like steroids).
Symptoms of Glaucoma
Glaucoma is often asymptomatic in its early stages. However, warning signs may include:
- Gradual loss of peripheral vision.
- Blurred vision.
- Eye pain or redness (in acute cases).
- Halos around lights.
- Sudden loss of vision (rare but urgent).
Who is at Risk?
- Age above 40.
- Family history of glaucoma.
- High eye pressure.
- Thin cornea.
- Diabetic patients.
- Long-term steroid use.
- Eye injuries or past eye surgeries.
How is Glaucoma Diagnosed?
A comprehensive eye examination includes:
- Tonometry: Measures intraocular pressure.
- Gonioscopy: Examines drainage angle.
- Optic Nerve Evaluation: Using slit lamp and OCT scans.
- Visual Field Test: To check for peripheral vision loss.
- Pachymetry: Measures corneal thickness.
Is Glaucoma Treatable?
While optic nerve damage cannot be reversed, glaucoma progression can be slowed or stopped with:
- Medicated Eye Drops: First-line treatment to lower eye pressure.
- Oral Medications: For cases where eye drops aren’t sufficient.
- Laser Therapy: Procedures like SLT (Selective Laser Trabeculoplasty).
- Surgical Options: Trabeculectomy, Glaucoma Drainage Devices, MIGS (Minimally Invasive Glaucoma Surgery).
Importance of Regular Eye Check-ups
Glaucoma is a lifelong condition that requires continuous monitoring. Annual comprehensive eye exams after age 40 (or earlier if you are at high risk) are crucial to detect glaucoma early when treatment is most effective.
Vision & Beyond Tip:
“Glaucoma doesn’t give you a warning before it steals your sight. Get your eyes checked today—even if you think your vision is perfect.”

How Is Glaucoma Diagnosed? Tests You Should Know About
Glaucoma is a silent, progressive disease that damages the optic nerve and can lead to irreversible blindness if not detected early. The good news? Early diagnosis and timely treatment can save your vision. But glaucoma can’t be diagnosed with just a simple vision or glasses power test.
A comprehensive glaucoma evaluation involves specialized tests that assess the eye pressure, optic nerve health, and visual function.
Here’s a detailed look at the key tests used to diagnose glaucoma:
1. Tonometry – Measuring Eye Pressure (Intraocular Pressure or IOP)
- What it is: A test to measure the pressure inside your eye.
- Why it’s important: High IOP is a major risk factor for glaucoma.
- How it’s done:
The most accurate method is Goldmann Applanation Tonometry (done in-clinic using a slit lamp).
Other methods include non-contact “air puff” tonometry and handheld devices.
- Normal Range: 10-21 mmHg. But remember, normal pressure doesn’t always rule out glaucoma (Normal-Tension Glaucoma).
2. Gonioscopy – Checking the Drainage Angle of the Eye
- What it is: A test to visualize the drainage angle where fluid exits the eye.
- Why it’s important: Determines whether the glaucoma is Open-Angle or Angle-Closure.
- How it’s done: A special contact lens with mirrors is placed on your eye after numbing drops. It’s a painless procedure.
3. Optic Nerve Head Evaluation (Ophthalmoscopy / Slit Lamp Exam)
- What it is: A detailed examination of the optic nerve head (the part of the optic nerve visible inside the eye).
- Why it’s important: Glaucoma damages the optic nerve in characteristic patterns like “cupping.”
- How it’s done: Using a slit lamp microscope and lenses, your doctor evaluates the optic disc’s shape, size, and nerve fiber health.
4. Optical Coherence Tomography (OCT) – Imaging the Optic Nerve and Retinal Nerve Fibers
- What it is: A non-invasive imaging scan that provides high-resolution, cross-sectional images of the optic nerve and surrounding retinal nerve fiber layers.
- Why it’s important: Detects structural damage even before vision loss occurs.
- How it’s done: A quick, painless scan where you look into a machine that takes detailed pictures in seconds.
5. Visual Field Test (Perimetry) – Checking Peripheral Vision Loss
- What it is: A functional test to assess how much of your peripheral (side) vision is affected.
- Why it’s important: Glaucoma typically affects side vision first, which is often unnoticed by patients.
- How it’s done: You’ll be asked to look at a central point while lights flash in various areas. You press a button every time you see a light.
- Frequency: Essential at diagnosis and regularly during follow-ups to monitor progression.
6. Pachymetry – Measuring Corneal Thickness
- What it is: A quick test to measure the thickness of your cornea.
- Why it’s important: A thinner cornea increases glaucoma risk and affects the accuracy of IOP readings.
- How it’s done: A probe gently touches the cornea after applying numbing drops. There are also non-contact methods.
7. Anterior Segment OCT (AS-OCT) or Ultrasound Biomicroscopy (UBM)
- What it is: Advanced imaging to get a detailed view of the anterior chamber angle and structures.
- Why it’s important: Especially useful in diagnosing narrow-angle or angle-closure glaucoma and for surgical planning.
- How it’s done: Quick scan without direct eye contact (for AS-OCT) or with a water bath contact probe (for UBM).
Glaucoma Diagnosis is a Combination of Tests
No single test can confirm glaucoma. Diagnosis is based on a combination of:
- Eye pressure measurements.
- Optic nerve appearance.
- Visual field testing.
- Structural imaging (OCT).
- Drainage angle assessment (Gonioscopy).
Your ophthalmologist at Vision & Beyond will decide which tests you need based on your risk factors, symptoms, and findings.
Take-Home Message
Glaucoma often progresses silently. Regular, detailed eye examinations that include glaucoma-specific tests are the only way to catch it early and preserve your vision. If you are over 40, have a family history, or other risk factors, don’t wait for symptoms—schedule a glaucoma screening today.
Vision & Beyond Tip:
“A simple glasses power test isn’t enough to detect glaucoma. Ask for a comprehensive eye check-up that looks beyond the surface.”

Minimally Invasive Glaucoma Surgery (MIGS): A New Era in Glaucoma Treatment
For decades, glaucoma surgeries were associated with complex procedures, long recovery periods, and significant risks. But today, advancements in technology have brought us into a new era of glaucoma treatment—the era of Minimally Invasive Glaucoma Surgery (MIGS).
MIGS offers a safer, quicker, and effective way to control eye pressure, especially for patients with mild to moderate glaucoma. If you’ve been struggling with eye drops or are concerned about traditional surgeries, MIGS might be the perfect solution for you.
What is MIGS?
Minimally Invasive Glaucoma Surgery (MIGS) refers to a group of surgical procedures designed to lower intraocular pressure (IOP) with:
- Smaller incisions
- Minimal tissue disruption
- Faster recovery times
MIGS procedures are typically performed alongside cataract surgery, but can also be done independently.
How Does MIGS Work?
MIGS procedures aim to:
- Improve fluid drainage through the eye’s natural pathways.
- Bypass blocked drainage channels.
- Reduce fluid production in the eye (in certain techniques).
Unlike traditional surgeries (like trabeculectomy or tube shunts), MIGS preserves much of the eye’s natural anatomy and carries fewer risks of complications like infections or hypotony (very low eye pressure).
Who is a Candidate for MIGS?
MIGS is suitable for patients who:
- Have mild to moderate Open-Angle Glaucoma.
- Are undergoing cataract surgery and want simultaneous glaucoma management.
- Struggle with eye drop compliance or experience side effects from medications.
- Prefer a safer alternative to traditional glaucoma surgeries.
MIGS is generally not recommended for advanced or aggressive glaucoma cases.
Common Types of MIGS Procedures
1. iStent / iStent Inject
- A tiny stent (smaller than a grain of rice) is implanted into the eye’s drainage channel (trabecular meshwork) to improve fluid outflow.
- Often done along with cataract surgery.
- Helps reduce or even eliminate the need for glaucoma drops.
2. Hydrus Microstent
- A flexible, crescent-shaped stent placed in the drainage canal (Schlemm’s canal).
- Increases outflow through a larger portion of the drainage system.
- Effective in reducing IOP long-term.
3. Trabectome
- A device that removes a small portion of the trabecular meshwork to create a direct fluid outflow path.
- Performed through a tiny incision with minimal tissue trauma.
4. GATT (Gonioscopy-Assisted Transluminal Trabeculotomy)
- A microcatheter is threaded through the eye’s drainage canal to open up 360 degrees of outflow.
- Helps restore natural drainage pathways.
5. Kahook Dual Blade (KDB)
- A precision blade is used to excise a strip of the trabecular meshwork, improving fluid outflow.
- Done through a small corneal incision.
6. XEN Gel Stent (Bridging MIGS and Traditional Surgery)
- A soft, gelatinous stent implanted to create a new drainage pathway.
- Used in cases where other MIGS procedures may not suffice but a full trabeculectomy is not ideal.
Advantages of MIGS
- Safer with lower complication rates.
- Quicker recovery time—most patients resume normal activities within days.
- Can be combined with cataract surgery.
- Reduces or eliminates dependence on glaucoma eye drops.
- Preserves the option for traditional surgeries later if required.
Limitations of MIGS
- Best suited for early to moderate glaucoma.
- May not achieve sufficient pressure reduction in advanced glaucoma cases.
- The long-term effectiveness varies depending on the procedure and individual factors.
Life After MIGS: What to Expect
- Most MIGS patients report smoother recoveries compared to traditional glaucoma surgeries.
- Regular follow-ups are still necessary to monitor eye pressure and optic nerve health.
- You might still require some eye drops, but the burden of medication usually reduces significantly.
Take-Home Message
MIGS represents a revolution in glaucoma care, offering a safer and gentler surgical alternative for patients seeking better IOP control with less disruption to daily life. At Vision & Beyond, we help you choose the best treatment plan tailored to your unique needs, ensuring your vision stays protected for the long haul.
Vision & Beyond Tip:
“Glaucoma treatment doesn’t have to be drastic. With MIGS, we take a small step surgically to make a big difference in preserving your sight.”

Myths vs Facts About Glaucoma – Busting Common Misconceptions
Glaucoma is one of the most misunderstood eye conditions. Because it often progresses silently, there are many myths and half-truths surrounding its causes, symptoms, and treatments. Unfortunately, these misconceptions can prevent people from seeking timely diagnosis and care.
Let’s debunk some of the most common myths and understand the facts about glaucoma:
Myth 1: “Glaucoma always causes eye pain and redness.”
- Fact: Most types of glaucoma, especially Primary Open-Angle Glaucoma (POAG), progress painlessly and without redness. It silently damages the optic nerve over months or years. Pain and redness are usually seen in Acute Angle-Closure Glaucoma, which is less common but a medical emergency.
Myth 2: “If my vision is fine, I don’t have glaucoma.”
- Fact: Glaucoma affects peripheral (side) vision first, which often goes unnoticed. Central vision usually remains unaffected until advanced stages. Many patients only realize vision loss after substantial optic nerve damage has occurred. Regular eye exams are essential—even if your vision feels perfect.
Myth 3: “Normal eye pressure means I don’t have glaucoma.”
- Fact: While high intraocular pressure (IOP) is a major risk factor, some people develop Normal-Tension Glaucoma (NTG) where optic nerve damage occurs even with normal IOP readings. Hence, a comprehensive eye exam including optic nerve evaluation and visual field testing is crucial.
Myth 4: “Glaucoma only affects elderly people.”
- Fact: While the risk of glaucoma increases with age, it can occur in young adults, teenagers, and even newborns. Congenital Glaucoma affects babies, and Juvenile Glaucoma can present in young adults. Family history increases the risk across all age groups.
Myth 5: “Glaucoma is curable with surgery.”
- Fact: Glaucoma cannot be cured, but it can be controlled. The goal of treatment (medications, lasers, or surgery) is to lower eye pressure and slow down or halt disease progression. Any vision already lost due to optic nerve damage is irreversible.
Myth 6: “Eye drops are optional once surgery is done.”
- Fact: In many cases, eye drops remain necessary even after surgery to keep eye pressure under control. Surgery reduces dependence on medications but may not eliminate them completely. Regular follow-up with your ophthalmologist is essential to monitor your condition.
Myth 7: “Glaucoma is contagious.”
- Fact: Glaucoma is not an infectious disease. You cannot catch it from someone else. However, it does have a genetic component, so family members of glaucoma patients are at higher risk and should get screened regularly.
Myth 8: “Only people with high eye pressure need glaucoma screening.”
- Fact: Relying solely on eye pressure to detect glaucoma is dangerous. Some patients have normal eye pressure yet still develop optic nerve damage (Normal-Tension Glaucoma). A detailed eye examination, including optic nerve imaging and visual field tests, is vital for accurate diagnosis.
Myth 9: “Wearing glasses prevents glaucoma.”
- Fact: Glasses or contact lenses correct refractive errors like myopia or hyperopia but have no role in preventing glaucoma. However, high myopia (severe nearsightedness) is a risk factor for developing glaucoma.
Myth 10: “Once diagnosed, glaucoma will always lead to blindness.”
- Fact: If detected early and treated appropriately, most glaucoma patients maintain good vision throughout their lives. Regular monitoring, medication compliance, and timely interventions are key to preventing vision loss.
Take-Home Message
Glaucoma is surrounded by myths that can delay diagnosis and treatment. Understanding the facts empowers you to take control of your eye health. Remember, glaucoma isn’t curable, but it is manageable—especially when caught early.

The Role of Family Screening in Glaucoma – Save Your Loved Ones’ Sight
Did you know that glaucoma can run in families? If you or someone in your family has been diagnosed with glaucoma, your close relatives are at a significantly higher risk of developing it too. Glaucoma often progresses silently, so regular eye screening of family members becomes a critical step in protecting their vision.
Let’s understand why family screening for glaucoma is essential and how it can help save the eyesight of your loved ones.
Why is Glaucoma a Family Matter?
Glaucoma is often hereditary. Studies show that:
- First-degree relatives (parents, siblings, children) of glaucoma patients are 4 to 9 times more likely to develop the disease.
- Certain genes associated with eye pressure regulation and optic nerve health are passed down through generations.
- In families where glaucoma is diagnosed, there’s often a pattern of delayed diagnosis, leading to advanced disease stages by the time it is detected.
This makes family history a strong and reliable risk factor.
Who in the Family Should Get Screened?
If you have glaucoma, these family members should undergo regular glaucoma screening:
1. Parents and siblings.
2. Children (especially after age 20-30).
3. Aunts, uncles, and cousins, especially if multiple cases are in the family.
Remember, glaucoma can affect anyone, even young adults, so early and regular screening is essential.
When Should Screening Begin?
- Children of glaucoma patients should start routine screenings by the age of 20-30 years, even earlier if there’s a strong family history or other risk factors.
- Adults over 40 years with a family history should have a comprehensive eye check-up at least once a year.
- If a family member is found to have increased eye pressure or early optic nerve changes, they will need closer monitoring and possibly preventive treatment.
What Does a Family Glaucoma Screening Involve?
A proper glaucoma evaluation is more than a routine vision test. It includes:
1. Intraocular Pressure (IOP) Measurement (Tonometry).
2. Optic Nerve Head Examination.
3. Visual Field Test (Perimetry) to check side vision.
4. Optical Coherence Tomography (OCT) for nerve fiber imaging.
5. Gonioscopy to examine drainage angles.
6. Corneal Thickness Measurement (Pachymetry).
These tests can detect glaucoma even before symptoms appear.
Benefits of Family Screening in Glaucoma
- Early Diagnosis = Better Control: Glaucoma damage is irreversible, but early detection allows effective treatment to halt progression.
- Protects Against Sudden Vision Loss: Some types of glaucoma, like Angle-Closure Glaucoma, can present suddenly. Screening can prevent emergencies.
- Improves Long-term Quality of Life: Early intervention reduces dependence on complex surgeries or aggressive treatments later on.
- Empowers Families to Be Proactive: Awareness within families encourages timely check-ups and reduces blindness rates.
Common Barriers to Family Screening
- “I can see fine, so I don’t need a check-up.”
- Lack of awareness about glaucoma’s hereditary nature.
- Belief that glaucoma is only an “old-age” problem.
As an eye care provider, it’s our mission at Vision & Beyond to spread awareness and emphasize that preventive screening is life-changing.
Take-Home Message
Glaucoma tends to stay silent until it’s too late. But it speaks loudly through your family history. If you or a loved one has glaucoma, encourage all at-risk family members to undergo comprehensive glaucoma screening. This simple step can save their vision.
Vision & Beyond Tip:
“Glaucoma can pass down through generations. A family check-up today can protect your family’s vision for a lifetime.”

Treatment Options for Glaucoma: Drops, Lasers, and Surgeries Explained
Glaucoma is a chronic eye condition where increased eye pressure damages the optic nerve, leading to gradual and irreversible vision loss. The good news? With timely diagnosis and proper treatment, most patients can preserve their vision and maintain a normal life.
The main goal of glaucoma treatment is to lower intraocular pressure (IOP) to prevent further optic nerve damage. Depending on the severity and type of glaucoma, treatment can range from simple eye drops to advanced surgeries.
Let’s explore the treatment options for glaucoma:
1. Medicated Eye Drops – The First Line of Defense
Most patients with glaucoma start their treatment with medicated eye drops. These drops either reduce the production of fluid in the eye or increase its drainage, thereby lowering eye pressure.
Common Types of Glaucoma Eye Drops:
- Prostaglandin Analogs (e.g., Latanoprost, Bimatoprost): Increase fluid outflow.
- Beta-Blockers (e.g., Timolol): Reduce fluid production.
- Alpha Agonists (e.g., Brimonidine): Reduce production and increase outflow.
- Carbonic Anhydrase Inhibitors (e.g., Dorzolamide): Reduce fluid production.
- Rho Kinase Inhibitors (e.g., Netarsudil): Improve drainage through a specific eye pathway.
Important Tips:
- Use them regularly as prescribed.
- Follow proper drop instillation techniques.
- Never stop drops without consulting your doctor.
2. Oral Medications – For Urgent Pressure Control
When eye drops alone aren’t sufficient, especially in acute situations, oral medications may be prescribed.
- Acetazolamide (Diamox): A carbonic anhydrase inhibitor that quickly reduces eye pressure.
- Used as a temporary measure before surgery or laser treatment.
3. Laser Therapy – A Minimally Invasive Solution
Laser treatments for glaucoma are painless, outpatient procedures that help reduce eye pressure by improving fluid drainage.
Types of Laser Treatments:
- Selective Laser Trabeculoplasty (SLT):
- Used in Open-Angle Glaucoma.
- Stimulates drainage channels to work more efficiently.
- Effect lasts several months to years and can be repeated.
- Laser Peripheral Iridotomy (LPI):
- Used in Angle-Closure Glaucoma.
- Creates a small hole in the iris to improve fluid flow and prevent sudden pressure spikes.
- Cyclophotocoagulation (CPC):
- Reduces fluid production by targeting the ciliary body.
- Typically used in advanced or refractory cases.
4. Surgical Procedures – For Advanced or Uncontrolled Glaucoma
When medications and lasers are insufficient, surgery becomes necessary to create new drainage pathways.
Common Surgical Options:
- Trabeculectomy:
- A surgical procedure that creates a new drainage channel (called a “bleb”) to lower eye pressure.
- Considered the gold standard surgery for moderate to advanced glaucoma.
- Glaucoma Drainage Devices (Tubes/Shunts):
- Tiny devices (e.g., Ahmed Valve, Baerveldt Implant) are inserted to help drain excess fluid.
- Preferred in complex cases where trabeculectomy may not be successful.
- Minimally Invasive Glaucoma Surgery (MIGS):
- Newer, less invasive surgical options designed for mild to moderate glaucoma.
- Examples include iStent, Hydrus Microstent, Trabectome.
- Can often be performed along with cataract surgery.
- Advantages: Safer, quicker recovery, fewer complications.
Choosing the Right Treatment Plan
Glaucoma management is customized to each patient based on:
- The type of glaucoma.
- The severity of optic nerve damage.
- Eye pressure levels.
- The patient’s age, lifestyle, and general health.
At Vision & Beyond, we believe in a stepwise approach—starting with the least invasive options and progressing to surgery when necessary.
The Importance of Continuous Monitoring
Even after successful treatment, glaucoma requires lifelong follow-up. Your doctor will monitor:
- Eye pressure levels.
- Optic nerve health.
- Visual field status.
Treatment may need to be adjusted over time depending on disease progression.
Take-Home Message
Glaucoma treatment is not one-size-fits-all. With a range of options—from simple drops to advanced surgeries—effective management is possible. The key is early diagnosis, consistent treatment, and regular follow-ups to protect your vision for life.
Vision & Beyond Tip:
“Glaucoma management is a journey. With the right treatment plan, you can stay a step ahead and safeguard your sight.”

What is Normal-Tension Glaucoma? Why You Need to Know About It
When most people think of glaucoma, they associate it with high eye pressure (intraocular pressure or IOP). However, there’s a lesser-known type called Normal-Tension Glaucoma (NTG) where optic nerve damage occurs even though eye pressure readings stay within the normal range.
NTG is tricky because it often goes undetected until significant vision loss has occurred. Understanding this silent threat is vital for early detection and preserving your vision.
What is Normal-Tension Glaucoma (NTG)?
In NTG, the optic nerve suffers damage and progressive vision loss despite eye pressure readings being in the “normal” range (10-21 mmHg). The exact cause isn’t fully understood, but it’s believed that:
- The optic nerve in NTG patients is more vulnerable to pressure damage.
- Poor blood flow to the optic nerve contributes to its degeneration.
How is NTG Different from Other Types of Glaucoma?
Feature Normal-Tension Glaucoma (NTG) Primary Open-Angle Glaucoma (POAG) Eye Pressure Normal (≤ 21 mmHg) Elevated (> 21 mmHg) Optic Nerve Damage Present Present Vision Loss Gradual Gradual Symptoms Often asymptomatic Often asymptomatic The damage patterns seen in NTG can sometimes be deeper and closer to the central vision earlier than in POAG.
Who is at Risk of NTG?
- Family history of glaucoma
- Thin corneas
- History of migraines
- Low blood pressure or nocturnal hypotension
- Sleep apnea (Obstructive Sleep Apnea – OSA)
- Systemic vascular conditions (poor blood circulation)
- Japanese and East Asian descent
What are the Symptoms of NTG?
Like other forms of glaucoma, NTG progresses silently. Most patients do not experience any symptoms in the early stages. However, as the disease advances, signs may include:
- Gradual loss of peripheral (side) vision.
- Difficulty seeing in dim lighting.
- Increased sensitivity to glare.
- Tunnel vision in advanced stages.
How is NTG Diagnosed?
Because eye pressure remains normal, NTG can be missed during routine eye checks that only measure IOP. A comprehensive glaucoma evaluation is necessary, which includes:
- Optic nerve examination (slit-lamp and OCT imaging)
- Visual field test (perimetry) to detect functional vision loss
- Gonioscopy to examine the drainage angle
- Monitoring for signs of optic disc cupping and nerve fiber layer thinning
If your doctor suspects NTG, they may also recommend a 24-hour IOP profile to rule out pressure fluctuations.
How is NTG Treated?
Even though eye pressure is normal, lowering it further can still protect the optic nerve and slow down damage.
Treatment options include:
1. Medicated Eye Drops
The primary treatment to further reduce IOP by 20-30%.
2. Laser Therapy (SLT)
May be considered in some cases.
3. Surgical Intervention
Rarely required but may be necessary if progression continues.
4. Managing Systemic Risk Factors:
- Controlling blood pressure (especially nocturnal dips).
- Treating sleep apnea.
- Improving blood circulation to the optic nerve.
Why NTG is Often Missed — And Why You Should Care
Many patients assume they are “safe” if their eye pressure is normal. Unfortunately, Normal-Tension Glaucoma progresses silently, and by the time vision loss is noticed, significant and irreversible damage may have occurred.
This makes regular comprehensive eye examinations—not just pressure checks—absolutely essential, especially if you have risk factors.
Take-Home Message
Normal-Tension Glaucoma is a deceptive form of glaucoma that silently damages vision despite normal eye pressure readings. Early detection through detailed eye exams and proactive treatment is crucial to prevent vision loss. Don’t wait for symptoms—get your eyes evaluated regularly.
