[Is a general operative prophylaxis of the fellow eye in cases of acute glaucoma necessary? (author's transl)].

The fellow eyes of 136 patients suffering from acute glaucoma were checked during their hospitalization by means of provocation-tests and gonioscopy. Ten cases had a simultaneous attack of both eyes, and 27 were submitted to a peripheral iridectomy prophylactically after a positive provocation-test. Of the remaining 99 patients observed up to 12 years after the operation only 22 developed an attack in the fellow eye; 11 of them were below the age of 60 years, and only 4 over 70.
