KNOW ABOUT GLAUCOMA

You need to be aware of this thieve of the eye known as GLAUCOMA. Glaucoma is a degenerative disease of the eye, which is caused as a result of build up pressure in the eye leading to damage of the optic nerve. 

There are three main types of glaucoma:
1. Open angle glaucoma
2. Closed-angle glaucoma
3. Congenital glaucoma

1
Open-angle glaucoma occurs when intraocular pressure builds up because fluids fail to drain from the eye normally. This additional pressure inside the eye may damage the nerves and lead to blindness, but not every case of open-angle glaucoma has excessive intraocular pressure.

2
Closed-angle glaucoma, also know as narrow -angle glaucoma occurs when the eye's drainage angle is blocked. The blockage creates increased intraocular pressure and nerve damage.

There are few reasons for this.
i. The iris and lens can be incorrectly positioned and block fluids from moving normally inside the eye chambers.
ii. If the iris is damaged, it can fall forward and block the drainage system.
iii. Following illness or injury, scar tissue can form between the cornea and iris and block the drainage system.

Congenital glaucoma is a form detected from birth. It is usually inherited from parents.

Secondary causes are also suspect in cases of glaucoma. It can be caused by an injury to the eye, following eye surgery, after a cataract forms, or after certain medications are administered, such as corticosteroids.
