Glaucoma: Protecting Your Vision for the Future

Glaucoma is often called the "silent thief of sight." This is because it usually develops slowly and without pain, affecting your side vision first. Because the changes are so gradual, many people don't realize their vision is at risk until a specialist identifies it.
‍
Mr. Mrinal Rana provides a supportive, expert environment to help you manage glaucoma. Using the latest technology, his goal is simple: to lower your eye pressure and protect your optic nerve so that your vision stays clear for life.

What causes Glaucoma?

Inside your eye, a clear fluid is constantly being produced and drained away. Think of it like a sink with a tap running: if the "drain" becomes slightly blocked, the water level doesn't overflow, but the pressure inside the sink builds up.
‍
In the eye, this Intraocular Pressure (IOP) puts stress on the optic nerve—the "cable" that connects your eye to your brain. Over time, this pressure can damage the delicate nerve fibers.

Are there different types?

Yes. Glaucoma is generally divided into two main categories based on how the fluid is being blocked:

• Open-Angle Glaucoma: This is the most common version. The drain looks open, but it doesn't work efficiently. It is a slow, lifelong condition that requires steady management.
• Angle-Closure Glaucoma: This happens when the "drain" is physically narrowed or blocked by the iris (the colored part of the eye). This can happen slowly, or it can happen very suddenly—which is a medical emergency that causes pain and blurred vision.
• Glaucoma associated with other eye diseases: This can happen after chronic inflammatory disorders or complex eye surgery leadind to damage to the drainage systems. 

What are the symptoms?

In the early stages, there are usually no symptoms. As the condition progresses, you might notice:

• A subtle loss of peripheral (side) vision.
• Difficulty seeing in dim light or "missing" objects to your side.
• In rare, sudden cases (Acute Glaucoma): Severe eye pain, headache, nausea, and seeing rainbow-colored halos around lights.

How do we treat it? (The "Stepped" Approach)

The primary goal of treatment is to lower the pressure in your eye to a "safe zone." Based on the latest medical evidence (specifically the LiGHT Trial), Mr. Rana follows a modern, patient-friendly path:

1. Selective Laser Treatment (SLT)

This is now often recommended as the first step. It is a gentle, 5-minute office-based laser treatment that helps the eye’s natural drain work better. It is painless, safe, and can often mean you don’t need to use daily eye drops.


2. Medicated Eye Drops

If laser treatment isn't enough, we use high-quality eye drops. Mr. Rana prioritizes preservative-free drops, which are much gentler on the eye and prevent the stinging or dryness often associated with older medications.



3. Modern "Micro-Surgery" (MIGS)

For patients who don't respond the medical management then may require to have these new tiny microscopic stents ( a MIGS Device) to make a new drainage pathway and improve circulation and control the pressure.

4. Trabeculectomy or Valve Implants:

This is the last resort or in complex eyes where standard management fails. Complex surgeries like Trabeculectomy or Glaucoma Valve implants may be needed and are performed by Super-specialists in Glaucoma.
