What Is Glaucoma? Why I Encourage Early Eye Screening

One of the most common concerns I hear in my clinic is, "What is glaucoma?" Many people assume that if they can see clearly, their eyes are healthy. However, glaucoma is a condition that often develops silently, causing damage before any symptoms become noticeable.

As an ophthalmologist in Dadar, Mumbai, I believe that understanding this condition is the first step towards protecting your eyesight.

What Is Glaucoma?

If you're wondering what is glaucoma, it is a group of eye diseases that gradually damage the optic nerve, which is responsible for sending visual signals from the eye to the brain. In many cases, this damage is associated with increased pressure inside the eye, although glaucoma can also occur with normal eye pressure.

The vision lost due to glaucoma cannot usually be restored, making early diagnosis extremely important.

Why Early Detection Is So Important

One of the biggest challenges with glaucoma is that it rarely causes pain or noticeable vision changes in its early stages. Patients often continue with their daily routine without realising that their peripheral vision is slowly being affected.

This is why I advise regular comprehensive eye examinations, especially for adults over 40 and individuals with known risk factors.

Who Should Be More Careful?

I recommend glaucoma screening if you:

• Have a family history of glaucoma
• Are over 40 years of age
• Have diabetes or hypertension
• Have high eye pressure
• Have a history of eye injury
• Use steroid medications for extended periods

Even if you don't have symptoms, regular check-ups can help detect glaucoma before significant vision loss occurs.

How Glaucoma Is Diagnosed

When I evaluate a patient for glaucoma, I perform several specialised tests rather than relying on a vision chart alone. These may include measuring eye pressure, examining the optic nerve, checking peripheral vision, and performing retinal imaging when necessary.

Together, these tests provide a clear picture of your eye health and help determine whether treatment is needed.

Can Glaucoma Be Treated?

Although glaucoma cannot be cured, it can usually be controlled with timely treatment. Depending on the stage of the disease, treatment may involve medicated eye drops, laser therapy, or surgery to reduce eye pressure and protect the optic nerve.

Regular follow-up appointments are equally important, as glaucoma requires lifelong monitoring.

Protect Your Vision Before Symptoms Appear

As an ophthalmologist in Dadar, Mumbai, I often remind my patients that prevention is far better than dealing with permanent vision loss. If you've ever asked yourself what glaucoma is, don't stop at finding the answer—take the next step by scheduling a comprehensive eye examination. Detecting glaucoma early can make all the difference in preserving healthy vision for years to come.
