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.
Using laser energy, a small hole in the iris (colored part of your eye) is made. This small hole allows fluid to flow between the back and front part of the eye, reducing the risk of future angle closure events. In some cases additional medication or surgical intervention is needed for treatment.
Using laser energy, the trabecular meshwork (drainage system of the eye) is treated in patients with open angles. This typically results in a reduction in intraocular pressure in many patients. Laser treatment is typically recommended when medication use is not sufficient to control the rate of glaucoma loss.
Trabeculectomy is a surgical treatment for glaucoma, and recommended when topical medications or laser treatment are not sufficient to control a patient's rate of loss. In this process, a new drainage site is created to facilitate drainage fluid of fluid from the eye. The fluid is drained into a new space that is completely covered by white outer covering of the eye. This will lower the eye pressure. Since the surgery is performed near the top of the eyes, the area of surgery can't be seen afterward.
