A consecutive series of 121 subcleral trepanations was studied for one year after surgery. The intraocular pressure in glaucoma simplex was less than 21 mm without therapy in 91% of Dutch white cases and in 71% of black Surinam cases. Histological examination revealed that corneal trepanations also gave good results.
