Glaucoma
Glaucoma is a disease of the eye in which fluid pressure within the eye rises - if left untreated the patient may lose vision, and even become blind. The optic nerve receives light-generated nerve impulses from the retina and transmits these to the brain, where we recognize those electrical signals as vision. Glaucoma is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision (peripheral vision). If glaucoma is not diagnosed and treated, it can progress to loss of central vision and blindness.
There are two main types of glaucoma
1.) Open angle glaucoma 2.) Closed angle (angle closure) glaucoma.
Symptoms of Glaucoma
* Sudden sight loss.
* Hazy or blurred vision.
* Severe eye and head pain.
* Nausea or vomiting (accompanying severe eye pain).
* The appearance of rainbow-colored circles around bright lights.
