Glaucoma is a group of eye diseases causing damage to the optic nerve that can lead to permanent vision loss and blindness if not treated.
- Increased intraocular pressure
Glaucoma is usually asymptomatic. Certain kinds may cause symptoms including:
- Sudden loss of vision
- Loss of peripheral vision
- Eye pain
- Sensitivity to light
- Lack of contrast sensitivity
- Nausea or vomiting
The damaged already caused by glaucoma is irreversible but if detected early, treatment can prevent further damage. It may include:
- Medication such as eye drops or pills to help drain the eye fluid to reduce pressure or to reduce the production of fluid
- Laser trabeculoplasty to help the fluid drain out
- Surgery to create a new opening for draining the fluid
There is no way to prevent glaucoma.
