The fornix-based conjunctival flap in glaucoma filtration surgery.

The use of a fornix-based conjuctival flap in trabeculectomy and in the combined trabeculectomy and cataract operation is described. Of 105 eyes subjected to trabeculectomy, the intraocular pressure was maintained at less than 21 mm Hg in 97 (92%). Of these 97 eyes, 58 (60%) required medication following the surgery. There were ten eyes in which combined trabeculectomy and cataract surgery was performed. All ten eyes had normal intraocular pressures postoperation; five (50%) with medication. This method has many advantages when compared with the limbal-based flap and gives excellent surgical results with few complications. The advantages are enumerated and the results are reported on 115 eyes operated on over the past ten years.
