What happens during a trabeculectomy for glaucoma?

In performing a trabeculectomy, your ophthalmologist (Eye M.D.) makes a small flap in the white of the eye, called the sclera. A filtration bleb, or reservoir, is created under the conjunctiva, the thin and clear coating that covers the sclera. The aqueous humor inside the eye can then drain through the flap to collect in the bleb, where it is absorbed into the lymph and blood vessels around the eye.

After the bleb is carefully constructed, the incision is closed with tiny stitches. Some of these stitches may be removed after surgery to increase fluid drainage.

Drugs to reduce scarring are often applied during and after surgery.
