[Long-term observation of ablatio-prophylaxis with kryopexy (author's transl)].

Prophylactic cryo coagulation is especially suitable when there is cloudy media, e.g. blood in the vitreous body or a cataract which would prevent light or laser coagulation. Cryo lesions applied under ophthalmoscopic control are without complication. The paper reviews the 116 eyes collected in 1971 and augments it with 202 eyes treated by 1975. Retinal detachment occured in 1.3% and new breaks occurred in 4%.
