[Long-term results of goniotrepanation with scleral flap].

Between 1970 and 1977 407 eyes were operated on for glaucoma of different origins, the procedure used being goniotrepanation with scleral flap. Ninety of these eyes were followed up for more than 5 years (7.2 years on average) with regard to long term effects of the operation. Open-angle glaucoma accounted for 73% of the cases. IOP was normal without drug treatment in 68 eyes (76%), and with drugs in a further 19 (21%). In other words, IOP was regulated for 5 years or more postoperatively in 97%. The investigation also covered the condition of the lens, (extension of cataract?), visual acuity and the morphology of the bleb.
