    Description

    Glaucoma causes fluid to build up in the eye, which increases pressure in the eye. This damages the optic nerve, which connects the eye to the brain, and can lead to permanent sight loss. In this procedure, a small flap is cut in the white of the eye (a trabeculectomy) and sewn up with loose stitches. A tiny patch (collagen matrix) is put over the flap to help healing and prevent scarring. Fluid slowly drains out of the flap and the patch dissolves over time (biodegradable). The aim is to reduce pressure in the eye and slow or stop damage to sight.
