Cataract is a cloudiness of the lens of the eye, that is the transparent structure in the eye which allows light to pass through the eye and focus on the retina at the back of the eyes.
Glaucoma (Silent thief of sight)
- What is glaucoma?
It is a group of diseases that result in damage to the main nerve of the eye responsible for vision- the optic nerve. This nerve is located at the back of the eye.
It is a type of cancer that affects the back of the eye (retina) in young children. It is the commonest cancer of the eye in children, affecting about one in about 15,000 -18,000 live births worldwide. It can affect one (unilateral) or both (bilateral) eyes.
Normally, when a person is trying to do near work (for instance threading a needle, reading a book, etc), the eyes accommodate. This simply means that a muscle in the eye (ciliary muscle) contracts, making the lens broader and shifting it forwards.
