Glaucoma is a group of conditions resulting in optic nerve damage that diminishes sight. High pressure inside the eye can cause this damage. Glaucoma can damage one’s vision so gradually it is not evident until the disease is at an advanced stage. There are two types of glaucoma, the most common being open-angle glaucoma and other, acute angle-closure glaucoma.
Symptoms may include:
- acute angle-closure glaucoma:
- severe eye pain
- nausea and vomiting
- sudden onset of visual disturbance
- blurred vision
- halos around lights
- reddening of the eye
Causes may include:
- increased intraocular pressure - this pressure comes from a buildup of aqueous humor - a fluid naturally and continuously produced in the front of the eye
- heredity
- damage to the eye caused by infection or inflammation
- tumor
- cataracts
- cataract surgery
Treatment may include:
- reducing intraocular pressure by improving aqueous outflow
- reducing the production of aqueous
- medicated eye-drops
- medication
Types include:
- acute angle-closure glaucoma - the drainage canals in the eyes becomes blocked because the angle between the iris and cornea is too narrow. The blockage and the pressure occurs rapidly.
- open-angle glaucoma - the drainage canals in the eyes becomes blocked because the angle between the iris and cornea is too narrow. The blockage and pressure in the eye builds slowly.
