Glaucoma Treatment Prayagraj (Allahabad)

What is Glaucoma (Kala Motia)?

Glaucoma is a group of eye conditions that damage the optic nerve, the vital connection between your eye and brain. In Hindi, glaucoma is commonly known as kala motia (काला मोतिया). It is often caused by abnormally high pressure inside the eye (intraocular pressure or IOP), though it can also occur with normal eye pressure.

Glaucoma is often called the "silent thief of sight" because it usually develops slowly and without noticeable symptoms in its early stages. By the time patients notice vision changes, significant and irreversible damage may have already occurred. This is why regular eye examinations are so important, especially after age 40.

The optic nerve is made up of more than a million tiny nerve fibres. When glaucoma damages these fibres, blind spots develop in your visual field. If left untreated, glaucoma can eventually lead to complete blindness. However, with early detection and proper treatment, most patients can preserve their remaining vision.

Why early detection is critical

Vision lost to glaucoma cannot be recovered. There is no way to restore nerve fibres once they are damaged. This is why screening is essential - catching glaucoma early means treatment can begin before significant vision loss occurs.

Types of Glaucoma

There are several types of glaucoma, each with different characteristics and treatment approaches.

Open-Angle Glaucoma

The most common type, accounting for about 90% of cases. The drainage angle of the eye remains open, but the trabecular meshwork becomes less efficient at draining fluid. Pressure builds up gradually, and vision loss occurs slowly over years. There are usually no early warning signs.

Angle-Closure Glaucoma

Occurs when the iris bulges forward and blocks the drainage angle. This can happen suddenly (acute attack) causing severe eye pain, headache, nausea, and blurred vision, which is a medical emergency. It can also develop gradually (chronic). More common in people with smaller eyes or farsightedness.

Normal-Tension Glaucoma

The optic nerve is damaged even though eye pressure remains within the normal range. The exact cause is not fully understood, but may be related to reduced blood flow to the optic nerve or increased nerve sensitivity. Requires regular monitoring and treatment to prevent progression.

Risk Factors for Glaucoma

While anyone can develop glaucoma, certain factors increase your risk. If you have one or more of these risk factors, regular eye exams become even more important.

Age over 40: Risk increases significantly with age, especially after 60
Family history: Having a parent or sibling with glaucoma increases your risk 4-9 times
Diabetes: Diabetic patients are at significantly higher risk of developing glaucoma
High myopia (nearsightedness): People with high minus power glasses are more susceptible
Previous eye injury or surgery: Trauma or certain surgeries can increase risk
Long-term steroid use: Prolonged use of corticosteroid medications (eye drops or oral)
High blood pressure: Both very high and very low blood pressure can be risk factors

How We Diagnose Glaucoma

A comprehensive glaucoma evaluation involves several tests. At Indumati Netralaya, we use modern diagnostic equipment to detect glaucoma at its earliest stage.

IOP Measurement (Tonometry)

We measure the pressure inside your eye using precise instruments. Elevated intraocular pressure is a key risk factor for glaucoma, though not all patients with high IOP will develop glaucoma.

Visual Field Testing (Perimetry)

This test maps your peripheral (side) vision to detect any blind spots or areas of reduced sensitivity. Visual field loss is one of the hallmark signs of glaucoma damage.

Optic Nerve Evaluation

Your doctor examines the optic nerve head (optic disc) using a special lens to look for characteristic changes such as cupping, which indicates nerve fibre loss from glaucoma.

Gonioscopy

A special lens is placed on the eye to examine the drainage angle, helping determine the type of glaucoma and the most appropriate treatment approach.

Treatment Options

The goal of glaucoma treatment is to lower eye pressure and prevent further damage to the optic nerve. Treatment typically starts with the least invasive option and escalates if needed.

Medicated Eye Drops

The most common first-line treatment. Prescription eye drops lower eye pressure by reducing fluid production or improving drainage. These must be used daily as prescribed. Regular follow-ups ensure the drops are working effectively.

Laser Treatment

Laser trabeculoplasty improves fluid drainage from the eye. It is a quick, outpatient procedure performed in the clinic. Effective for patients who cannot tolerate eye drops or need additional pressure reduction alongside medication.

Surgery (Trabeculectomy)

When eye drops and laser are insufficient, surgical options create a new drainage pathway for fluid to leave the eye. Trabeculectomy is the most common glaucoma surgery, providing long-term pressure control for advanced cases.

Why Early Detection Matters

Glaucoma is one of the leading causes of irreversible blindness worldwide. Unlike cataracts, where vision can be restored with surgery, vision lost to glaucoma is permanent. The optic nerve cannot regenerate once damaged.

This is why we strongly recommend regular eye pressure checks for everyone over 40, and especially for those with risk factors. Early glaucoma has no symptoms that you would notice on your own. By the time you notice vision changes, up to 40% of your optic nerve fibres may already be lost.

The good news is that with modern diagnostic tools, we can detect glaucoma much earlier than before. And when caught early, treatment is highly effective at preserving your remaining vision for a lifetime.

Our recommendation

Everyone over 40 should have a comprehensive eye exam that includes IOP measurement every 2-3 years. If you have risk factors, annual screening is recommended. If you have been diagnosed with glaucoma, follow your prescribed treatment plan carefully and never skip follow-up appointments.

Glaucoma cannot be cured, but it can be effectively managed with proper treatment. Vision lost to glaucoma cannot be recovered, which is why early detection is critical. With regular use of prescribed eye drops, laser treatment, or surgery, further vision loss can be prevented or significantly slowed.

People over 40, those with a family history of glaucoma, diabetics, individuals with high myopia (nearsightedness), people who have had eye injuries, and those on long-term steroid medications are at higher risk. Regular eye exams are recommended for all people over 40.

If you are over 40 with no risk factors, get tested every 2-3 years. If you have risk factors such as family history, diabetes, or high myopia, annual testing is recommended. If you have been diagnosed with glaucoma, follow your doctor's schedule which may include visits every 3-6 months.
