[Prophylactic lasercoagulation of senile retinoschisis (author's transl)]

135 patients with senile retinoschisis were treated by argon laser coagulation. 73 of them were reexamined after an average interval of 15 months. The treatment consisted of a posterior demarcation by 2-3 lasercoagulation series in the area of the normal retina and in addition treatment of the entire area of retinoschisis. Lasercoagulation was performed, when: 1. the retinoschisis reached the equator or extended postequatorially, 2. a hole in the outer layer was detected, 3. a retinal detachment proceeded from a retinoschisis in the other eye.
