[Possibilities of the treatment of senile retinoschisis].
Photocoagulation and cryopexy were applied in 5 patients with retinoschisis; in 3 they were connected with a temporary invagination of the sclera by means of a Lincoff-Kreissig balloon. After the photocoagulation the authors attained the control of the increase of schisis in 3 patients; in 1 woman-patient a progress of pathological changes was seen. Cryopexy connected with a temporary invagination lead to a good result in a case not formerly treated. The same method in patients treated before by the photocoagulation of the detachment area was definitely less effective. It was suggested that the use of invagination and pressure upon the eye after the break of the choroi-retinal barrier may speed-up the absorption of the fluid from schisis cavity.
