[A case of nonarteritic anterior ischemic optic neuropathy with cilioretinal artery occlusion].
We report a case of nonarteritic anterior ischemic optic neuropathy (AION) with cilioretinal artery occlusion. The patient was a 61-year-old man with sudden visual loss in his right eye. Funduscopy showed pale swelling of the entire optic disc with retinal ischemic edema of the upper half of the retina, and fluorescein angiography revealed faint filling of the dye in the optic disc in the retinal arterial phase, and dye staining of the optic disc in the late phase. We initially diagnosed the disease as AION with branch retinal artery occlusion, but systemic administration of a corticosteroid and urokinase were ineffective and the optic disc became atrophic. As the optic disc swelling decreased and the course of arteries in the optic disc became clear, we repeated fluorescein angiography which proved that the involved upper retinal artery was a cilioretinal artery having earlier dye appearance than the lower retinal artery. Thus, we finally diagnosed the disease as AION with cilioretinal artery occlusion. We believe that Hayreh's view that AION may result from occlusion of the posterior ciliary artery is supported by the intraocular findings in this case.
