[The electro-oculogram in the early postoperative period following fistulizing operations (author's transl)].

EOGs were obtained from 2 groups of patients suffering from glaucoma chronicum simplex the day before surgery and 3, 5, 8, 11 and 14 days after trephining or fistulizing operation after Scheie. Though and peak potentials of the treated eyes were significantly less than those of the untreated fellow eyes five days after surgery. In addition on the 11. postoperative day after Scheie a second potential decrease was seen. The EOG-changes observed appear to reflect disturbances of the choroidal circulation after fistulizing operations.
