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.
