ABSTRACT:
An iris scraping surgical method treats pigmentary glaucoma in which the pigment attaches to the underside of the iris. An incision is made in the sclera. The iris is lifted and pigment and/or cellular debris is scraped with a scalpel from the bottom layer (pigment epithelium) of the iris. The iris lifted up from the lens to remove the build up of escaping pigment on that layer to let the fluid flow out at a normal rate to drain out of the trabecular meshwork and then the iris is lowered and the incision in the sclera is closed.
