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.
一名81岁女性在发生视网膜中央动脉阻塞(CRAO)后,左眼出现了视网膜中央静脉阻塞(CRVO)。她注意到左眼突然视力丧失。初次检查时,她的左眼视力为0.03,仅颞侧保留了一小片视野。左眼眼底显示轻度非缺血性CRVO的表现。此外,在左后极可见视网膜呈白色混浊,提示CRAO。荧光素血管造影(FAG)显示动脉循环明显延长,但无视网膜毛细血管闭塞。随后视网膜出血迅速增加,左眼发展为出血性视网膜病变。初次检查两周后,FAG显示广泛的视网膜毛细血管闭塞。在这种情况下,推测由于动脉硬化导致的视网膜中央动脉阻塞产生了缺血性毛细血管病变和静脉血栓形成,之后动脉循环的恢复导致了出血性视网膜病变。
