[A case of central retinal vein occlusion accompanied by central retinal artery occlusion].

A 81-year-old woman developed central retinal vein occlusion (CRVO) in her left eye subsequent to central retinal artery occlusion (CRAO). She noticed sudden visual loss in the left eye. At initial examination, her left visual acuity was 0.03, and only a small visual field was preserved at temporal area. The left fundus showed findings of mild non-ischemic CRVO. In addition white clouded retina was recognized at the left posterior pole which indicated CRAO. FAG showed remarkably prolonged arterial circulation, but no retinal capillary obliteration. Then retinal hemorrhage increased rapidly and her left eye developed hemorrhagic retinopathy. Two weeks after initial examination, FAG showed extensive retinal capillary obliteration. In this case it was supposed that central retinal artery occlusion due to arteriosclerosis produced ischemic capillaropathy and venous thrombosis, after which restoration of arterial circulation caused hemorrhagic retinopathy.
