Glaucoma: The Silent Thief of Vision You Shouldn’t Ignore

by

Glaucoma is often called the “silent thief of sight”—and for good reason. It creeps up slowly, damaging the eye without showing obvious warning signs in the beginning. By the time a person realizes something is wrong, permanent vision loss may have already set in. Unlike many other eye problems that can be corrected with glasses, surgery, or medication, glaucoma-related vision loss is irreversible.

This naturally raises questions: What exactly is glaucoma? Who gets it? Is it only about high eye pressure? Can it really make me go blind without symptoms? These are the doubts most people have, and they’re the right ones to ask.

Globally, glaucoma is one of the leading causes of blindness. But in India, the situation is even more worrying. Studies estimate that over 12 million Indians live with glaucoma, and nearly 1.5 million have already lost their eyesight because of it. Even more concerning is that nine out of ten cases remain undiagnosed. The reason is simple—most people don’t make routine eye check-ups a priority. Instead, they wait until symptoms interfere with daily life, and by then, it’s often too late.

The good news? With timely eye examinations, early diagnosis, and the right treatment, vision loss from glaucoma can almost always be prevented.

Understanding Glaucoma: Symptoms, Causes, and Treatment

What is Glaucoma?

Glaucoma isn’t a single disease—it’s a group of eye conditions that share one thing in common: damage to the optic nerve. This nerve acts like a communication cable, carrying visual information from your eyes to your brain. When it’s damaged, that pathway breaks down, and parts of your vision start to fade.

The primary culprit is usually increased intraocular pressure (IOP)—too much fluid building up inside the eye. Over time, this pressure silently erodes the optic nerve, leading to gradual and permanent loss of vision, often without any early symptoms.

Symptoms of Glaucoma

The early stages of glaucoma usually have no symptoms, which is why it’s often called the “silent thief of sight.”

As the disease progresses, you may experience:

  • Gradual loss of peripheral (side) vision, leading to tunnel vision
  • Blurred or hazy vision
  • Red or irritated eyes
  • Eye pressure or discomfort
  • Headaches or mild eye pain
  • Double vision in some cases

In certain types like acute angle-closure glaucoma symptoms can appear suddenly and require emergency treatment. These include:

  • Severe eye pain
  • Headache with nausea or vomiting
  • Sudden blurred vision or halos around lights
  • Rapid loss of vision

If you ever experience these symptoms, it’s a red flag to see an eye specialist immediately.

Causes and Risk Factors

Glaucoma develops when the fluid inside the eye, called aqueous humor, doesn’t drain properly. This leads to fluid buildup and increased eye pressure. But the story isn’t that simple. Not everyone with high eye pressure develops glaucoma, and sometimes glaucoma can occur even with normal pressure.

Common risk factors include:

  • Age: Risk rises after 40, and increases sharply after 60.
  • Family history: If someone in your family has glaucoma, your risk is higher.
  • Ethnicity: Asians (including Indians) are more prone to angle-closure glaucoma.
  • Medical conditions: Diabetes and high blood pressure increase risk.
  • Refractive errors: Severe myopia (nearsightedness) or hyperopia (farsightedness).
  • Steroid use: Long-term use of corticosteroid medications can trigger secondary glaucoma.
  • Eye injuries: Trauma can damage drainage structures, leading to glaucoma.

In India, where diabetes and hypertension are already widespread, the risk of glaucoma is even higher.

Types of Glaucoma

Glaucoma is not one-size-fits-all. The main types include:

  1. Open-Angle Glaucoma:
    • The most common type.
    • Develops slowly over years.
    • Often symptomless until vision loss occurs.
  2. Angle-Closure Glaucoma:
    • Less common, but more dangerous.
    • Happens when the drainage angle in the eye gets blocked.
    • Can cause sudden, severe symptoms and requires immediate treatment.
  3. Secondary Glaucoma:
    • Caused by other conditions like diabetes, eye injury, inflammation, or steroid use.
  4. Congenital Glaucoma:
    • Rare, but present at birth.
    • Caused by developmental problems in the eye’s drainage system.

How Glaucoma is Diagnosed

Because glaucoma is silent in the early stages, the only reliable way to catch it early is through regular eye checkups. At Innocent Hearts Eye Centre, Jalandhar, we use advanced diagnostic tools to detect glaucoma at the earliest possible stage.

Tests include:

  • Tonometry: Measures eye pressure.
  • Visual field test: Detects blind spots or loss of side vision.
  • Optical Coherence Tomography (OCT): Provides detailed images of the optic nerve and retinal layers.
  • Gonioscopy: Examines the drainage angle of the eye.
  • Slit-lamp exam: For detailed evaluation of eye structures.
  • Pachymetry: Measures corneal thickness, which influences pressure readings.

Regular screening is especially important for those above 40, people with diabetes, or those with a family history of glaucoma.

Treatment Options for Glaucoma

Glaucoma can’t be cured, but it can be controlled. The goal of treatment is to lower eye pressure and prevent further optic nerve damage.

1. Medications:

  • Prescription eye drops are the most common treatment.
  • These work by either reducing fluid production or improving fluid drainage.

2. Laser Treatment:

  • Procedures like selective laser trabeculoplasty (SLT) can help open drainage channels.
  • Useful in both open-angle and angle-closure glaucoma.

3. Surgery:
 When medicines or lasers aren’t enough, surgery may be recommended:

  • Trabeculectomy: Creates a new drainage pathway.
  • Tube shunt surgery: Implants a device to drain excess fluid.
  • Minimally Invasive Glaucoma Surgeries (MIGS): Safer, quicker procedures with faster recovery.

At Innocent Hearts Eye Centre, we use advanced surgical techniques and state-of-the-art equipment to manage even the most complex cases.

Living with Glaucoma

A glaucoma diagnosis doesn’t mean you’ll lose your vision. With timely treatment and consistent care, most people retain useful vision throughout their lives.

Here’s how you can manage it:

  • Stick to your treatment plan. Use your drops and medicines regularly.
  • Don’t skip follow-ups. Regular monitoring is key to adjusting treatment.
  • Manage systemic health. Control blood sugar and blood pressure.
  • Protect your eyes. Wear protective eyewear to avoid injury.
  • Be aware. Any new symptoms should be reported immediately.

When to Seek Immediate Medical Help

Glaucoma is a slow disease in most cases, but sometimes it strikes fast. Seek urgent help if you have:

  • Sudden, severe eye pain
  • Blurred or lost vision
  • Halos around lights
  • Eye pain with nausea or vomiting

Delaying care in such situations can mean permanent vision loss.

Frequently Asked Questions (FAQs) About Glaucoma

1. What is the main cause of glaucoma?
The main cause of glaucoma is damage to the optic nerve, usually due to increased intraocular pressure (IOP). This happens when fluid inside the eye doesn’t drain properly, creating pressure that slowly harms the nerve. Other risk factors like age, family history, diabetes, and eye injuries can also contribute.

2. Can glaucoma be cured?
Glaucoma cannot be reversed once the optic nerve is damaged. However, the disease can be managed with timely treatment. Eye drops, laser therapy, and surgeries are effective in lowering eye pressure, helping preserve vision for years. Early diagnosis is the key to preventing severe vision loss.

3. What are two common signs of glaucoma?
Most early cases show no symptoms. But two of the earliest signs are gradual loss of side (peripheral) vision and seeing halos around lights. Some patients may also notice blurry vision or frequent changes in eyeglass prescriptions.

4. What is first stage glaucoma?
In the first stage, glaucoma causes mild damage to the optic nerve that usually goes unnoticed. Vision often looks normal to the patient, but eye exams may reveal small blind spots or pressure changes. This stage is when treatment is most effective.

5. How can I check for glaucoma at home?
You cannot diagnose glaucoma at home. While you may notice blurred vision, headaches, or tunnel vision in later stages, only a doctor can confirm glaucoma through pressure tests and optic nerve scans. Regular screenings are the only reliable way to detect it early.

6. Can stress cause glaucoma?
Stress itself does not directly cause glaucoma, but it may raise eye pressure temporarily in some people. Long-term stress can also affect blood circulation to the optic nerve. While managing stress is healthy, it should not replace medical treatment or eye exams.

7. How is glaucoma confirmed?
Doctors use several tests to confirm glaucoma: measuring eye pressure (tonometry), examining the drainage angle (gonioscopy), imaging the optic nerve (OCT), and checking for blind spots with visual field testing. A combination of these results helps diagnose the disease accurately.

8. At what age does glaucoma usually start?
Glaucoma risk rises significantly after age 40, though it can appear earlier. People with a family history, diabetes, or high eye pressure are more likely to develop it sooner. Babies and children can also have rare forms like congenital glaucoma.

9. What are signs of optic nerve damage?
Signs include blind spots in your vision, fading colors, difficulty seeing in low light, and eventually tunnel vision. Since nerve damage is permanent, early detection is critical to preserving sight.

10. Which vitamin deficiency causes glaucoma?
No single vitamin deficiency directly causes glaucoma. However, poor nutrition may worsen optic nerve health. Antioxidants like vitamins A, C, E, and B12 support healthy eyes and may reduce the risk of nerve damage.

11. What habits can increase glaucoma risk?
Habits like smoking, heavy alcohol use, excessive caffeine, poor sleep, and long-term steroid use can worsen eye pressure. Skipping regular check-ups also increases risk, since glaucoma often develops silently.

12. Is glaucoma related to the brain?
Yes. Glaucoma damages the optic nerve, which connects the eye directly to the brain. When nerve fibers die, the brain doesn’t receive clear signals, leading to vision loss. Some researchers compare glaucoma to neurodegenerative conditions like Alzheimer’s.

13. What is the best treatment for glaucoma?
The best treatment depends on the patient. Doctors may prescribe eye drops to reduce pressure, perform laser treatments, or suggest surgeries. Minimally invasive procedures (MIGS) are newer options that help lower pressure with faster recovery times.

14. How quickly can glaucoma cause blindness?
It varies by person. In aggressive cases, untreated glaucoma may lead to blindness in just a few years, while slower cases may take decades. With proper treatment and follow-ups, most people retain useful vision for life.

15. Can I still drive with glaucoma?
Yes, if the disease is detected early and vision remains stable. Advanced glaucoma may reduce side vision and make driving unsafe. Patients should get regular eye checks and follow local driving laws.

16. How can I prevent glaucoma naturally?
You can’t fully prevent glaucoma, but you can lower risk with regular eye exams, healthy diet, exercise, and protecting your eyes from injuries. Avoid smoking, manage chronic conditions like diabetes, and stay consistent with prescribed treatments.

17. What are the new treatments for glaucoma?
Innovations include minimally invasive glaucoma surgeries (MIGS), sustained-release drug implants, and advanced laser therapies. These newer treatments reduce the need for daily drops and lower long-term eye pressure more effectively.

18. Is glaucoma linked to diabetes?
Yes. Diabetes increases the risk of developing glaucoma, particularly open-angle glaucoma. High blood sugar can damage eye blood vessels and drainage channels. Diabetic patients should have annual comprehensive eye exams.

19. Who gets glaucoma the most?
People over 40, those with a family history of glaucoma, diabetics, and people of African or Asian descent are at the highest risk. Individuals with high eye pressure or past eye injuries are also more likely to develop it.

20. What is the end stage of glaucoma?
In end-stage glaucoma, most vision is lost, leaving only small central vision or total blindness. At this stage, treatment focuses on maintaining quality of life and preventing discomfort rather than restoring vision.

21. What is the difference between glaucoma and cataracts?
Glaucoma damages the optic nerve due to high eye pressure, causing permanent vision loss. Cataracts, on the other hand, cloud the eye’s natural lens, leading to blurry vision. Cataracts can be cured with surgery, but glaucoma damage cannot be reversed.

22. How long can I live with glaucoma?
Glaucoma itself doesn’t shorten lifespan. People can live a full life if the disease is managed properly. The key is early diagnosis and lifelong treatment to preserve vision and independence.

23. How to sleep with glaucoma?
Sleeping with your head slightly elevated on a pillow can help reduce eye pressure at night. Avoid sleeping face-down or on the same side as your affected eye. Consistent sleep routines and managing sleep apnea also support better eye health.

24. How to check eye pressure with fingers?
You cannot accurately check eye pressure with your fingers. While doctors sometimes gently press the eye to compare firmness, only proper tools like a tonometer give reliable results. Self-checking at home is not safe or accurate.
