Glaucoma is a disease in which elevation of eye pressure causes damage to the nerve and subsequent loss of vision. The condition can usually be managed with drops and in office laser treatment. In more advanced cases, surgical treatment is necessary to control the pressure and preserve vision.
Trabeculectomy surgery is a technique in which the surgeon creates a partial thickness drainage hole in the sclera. The drainage hole allows the slow filtration of fluid from the eye. This lowers eye pressure and prevents further vision loss from glaucoma.
The majority of patients experience a reduction in eye pressure and preservation of vision following trabeculectomy.
Complications include loss of vision, bleeding, infection, corneal edema, cataract, ocular misalignment causing double vision, low eye pressure, or serous choroidal detachment. Serious complications are uncommon, but patients undergoing trabeculectomy surgery do require careful management and close follow up.
Glaucoma can cause permanent loss of vision. Topical drops and laser treatment are usually adequate to lower eye pressure and preserve vision. In more advanced cases, surgical treatment is necessary to control the disease. Trabeculectomy is an effective technique to lower eye pressure in selected patients.
