Glaucoma is a condition that causes damage to the eyes optic nerve. There are two main forms of glaucoma, open angle and closed angle. The difference between the two is in the relationship between the colored part of your eye (iris) and the drainage system (trabecular meshwork). In closed angle glaucoma, the drainage system is blocked anatomically by the eye's own structures such as the iris. Treatments for open angle and angle closure are different.
Treatment for angle closure glaucoma typically includes a laser procedure, and topical medications to control the eye pressure. Depending on your eyes anatomy, your surgeon might also recommend other surgical intervention.
Although the exact cause of open angle glaucoma is not known, its progression can be slowed by reducing the pressure inside the eye. Pressure reduction is often achived with the use of topical medications that are used on a daily basis. When eyedrops can no longer control the rate of loss, surgical intervention is recommended.
