[Photocoagulation for central vein occlusion (author's transl)].

27 patients with fully developed central vein occlusion were treated by means of photocoagulation. In all cases, a relatively quick regression of retinal hemorrhage and retinal edema occurred, as well as an extensive nomalisation of the caliber of the veins. In over 1/3 of cases, improvement of visual acuity could be achieved; acuity decreased in 1/3 of cases because of macula alterations (fibrosis, cystic edema, pigmentary dystrophy). The results, however, showed a general improvement as compared to disease courses left untreated. None of the patients developed secondary glaucoma during case control which can be assessed as the most significant result of photocoagulation.
