Glaucoma

Types of Glaucoma

Open Angle Glaucoma

This is the commonest form of glaucoma. It can cause a gradual loss of vision, leading eventually to blindness. It is a slowly progressive disease. Open angle glaucoma causes no symptoms until the disease is very advanced, when sufferers began to lose even their central vision.

Open angle glaucoma occurs when the trabecular meshwork, through which the fluid inside the eye drains, becomes partially blocked. The pump which pumps fluid into the eye continues to pump at the same rate. The additional fluid, which cannot drain away, raises the pressure inside the eye. This raised pressure damages the optic nerve, ultimately causing loss of sight.

Narrow Angle Glaucoma

A small number of people with slowly progressive, symptomless glaucoma will have narrow angle glaucoma. People with narrow angle glaucoma tend to have shorter eyes than average and therfore tend to have hyperopia (or long-sightedness).

If untreated narrow angle glaucoma can suddenly progress to closed angle glaucoma, an acute glaucoma causing pain and sudden loss of vision..

It is important that narrow angles ar detected, because the treatment differs from open angle glaucoma. Only a thorough examination of the eye can detect narrow angles.

Closed Angle Glaucoma

This condition can lead to pain rapid loss of sight and ultimately blindness if not treated quickly. Closed Angle Glaucoma requires emergency treatment with drops and sometimes tablets, or even injections of drugs to reduce the eye pressure.
