A 44-YEAR-OLD woman complained of sudden visual loss in her right eye, which again deteriorated 2 days later. A month after the episode, she had a visual acuity of counting fingers at 15 cm OU and was diagnosed as having a central retinal artery occlusion. The retinal nerve fiber layer was attenuated and the optic disc was slightly pale. Mild capillary dilation was present in several segments of the disc rim (Figure 1). Blood pressure was 160/104 mm Hg and examination results revealed calcific aortic valvular stenosis. Seven months later, the retinal nerve fiber layer was absent and large cilioretinal anastomoses surrounded the optic disc (Figure 2).
