We evaluated the circulation of the posterior retina in a case of acute retinal necrosis syndrome through repeated fluorescein angiography for eight months. The patient was 24-year-old man. His left fundus showed typical acute retinal necrosis syndrome, that is, yellowish-white opacity in all the circum-stance of the peripheral fundus, retinal artery whitening, retinal vein dilation and tortuosity, and optic neuritis. Fluorescein angiography showed no occlusion of vessels in the posterior retina. Two weeks after onset, we performed vitrectomy. But we needed re-vitrectomy and silicone oil tamponade because of increasing vitreal opacity. Four weeks after onset, fluorescein angiography showed broad occluded capillary bed in the posterior retina.

Four months after onset, most of these non-perfused areas disappeared and were replaced by rough capillary network and coil-like pattern vessels surrounding residual occluded area. We concluded these vessels were intraretinal neovascularization judging from its fluorescein angiographic findings. All occluded areas were replaced by newly-formed capillary network. We emphasized the importance of the microcircula-tion of the posterior retina as well as the finding of the peripheral fundus in acute retinal necrosis syndrome.
