Glaucoma

Overview

Glaucoma refers to a group of eye diseases that cause progressive damage to the optic nerve. Glaucoma is one of the leading causes of blindness in the India. The damage caused by glaucoma is permanent, but early diagnosis and treatment can usually prevent vision-threatening damage.

The key to successfully treating glaucoma is diagnosing it early, before extensive damage has occurred. In the most common form of glaucoma, open-angle glaucoma, there are no symptoms of the disease until the damage is very advanced. That's why it's so important to have periodic eye check-ups, particularly if you are at high risk for developing glaucoma.

 
What is Glaucoma?  

The eyes have its own internal “plumbing” system that circulates a fluid called aqueous through the eye around the human lens and iris (coloured circle of the eye).

 

Aqueous nourishes the front parts of the internal eye and helps to maintain normal pressure which is needed for the normal shape and function of the eye. This aqueous has nothing to do with tears produced by the eye.

Aqueous is constantly produced by the ciliary body in the eye and drained out via the angle of the eye into the general blood stream. When something goes wrong with this plumbing system – usually because of drainage system block or too much fluid build up in the eye, the intraocular pressure rises.


This high pressure produced due to the imbalance in the amount of fluid produced and the amount drained out, puts a strain on the delicate nerve structures in the back of the eye called the optic nerve.


The optic nerve is like an electric cable containing a million wires. Each wire or nerve fibre carries messages to the brain and these messages join together and are interpreted as vision by the brain. Glaucoma can damage these nerve fibres, causing blind spots to develop.
