Methods To observe the changes of psoterior po lar of retina in 7 eyes of 7 patients,which were retinal edema,haemor rhage,vessel occlusion and later optic atrophy.5 eyes were given exami nations of fundus fluorescein angiography(FFA). Results The FFA showed large non-perfusion area, staining and leakage of vessel wall, and later hyperfluorescence of optic disc. Visual progjosis is very terrible.
