About Glaucoma Filtration Surgery
Glaucoma filtration surgery is also known as trabeculectomy. It is done as an outpatient surgery with a local anesthetic. You may be given a sedative to help you relax. The procedure is usually performed in less than an hour. Your Eye M.D. will make a small flap in the white of the eye (the sclera). This is followed by the creation of a reservoir called a filtration bleb. The aqueous humor can drain into this reservoir and be absorbed into the blood vessels around the eye. After carefully constructing the filtration bleb, your doctor will close the incision in the sclera with tiny stitches. Some of these stitches may be released after surgery to increase fluid drainage. Drugs to reduce scarring are often applied during and after surgery. Although the success rate is quite high, sometimes a single surgical procedure cannot halt the progression of glaucoma. Another surgery and/or continued treatment with medications may be necessary.
