Glaucoma implants. Their use in difficult cases of glaucoma.

Implants with a regime of fibrosis suppression (prednisolone 30 mg daily plus fluphenamic acid 200 mg three times a day for 6 to 8 weeks) controlled the intraocular pressure (applanation tonometry (AT) less than 21 mm Hg) in seven out of ten patients with different types of glaucoma. One implant was removed after erosion of the conjunctiva and sclera; there were no other serious complications. Use of the implant is indicated after failed drainage operations or as a primary procedure in glaucoma associated with aphakia, chronic uveitis, vitreous in the anterior chamber, and scarring of the conjunctiva.
