GLAUCOMA

 

Glaucoma is a group of conditions where the optic nerve inside the eye is damaged, often associated with raised pressure inside the eye. There are different types of Glaucoma, and often will not cause any symptoms in the early stages.

THERE ARE 4 MAIN TYPES OF GLAUCOMA

 

Chronic open-angle glaucoma – This is the most common type that develops slowly.. Pressure within the eye increases when the tubes that allow fluid to flow naturally from the eye become slightly blocked. Possible signs include tunnel vision, and a gradual loss of peripheral (side) vision. Many people are diagnosed at a regular eye examination.

 

Acute angle-closure glaucoma – This is a medical emergency and often occurs rapidly, with a sudden and more acute blockage to the flow of fluid from the eye. Symptoms include severe pain, blurred vision (especially in dim light) halos around lights , red eyes, headaches, nausea and vomiting.

 

Secondary glaucoma – Certain eye conditions, or after eye surgery, trauma to the eye or medication can also raise the pressure within the eye.

 

Developmental glaucoma (congenital glaucoma) – This is usually present at birth or shortly after. The child might not want to open their eyes in the light, and the eye may look cloudy or teary. It is rare, but can be serious, as it is caused by an abnormality of the eye.
