The surgical treatment of open-angle glaucoma in Nigerians.

The results of trabeculectomy and sclerectomy procedures for open-angle glaucoma in African Negroes are compared. Trabeculectomy produced fewer long-term complications, but otherwise there was little difference in their results. Excision of Tenon's capsule and the use of local corticosteroids postoperatively are probably significant in preventing failure of aqueous drainage from subconjunctival fibrosis.
