목적 : To report a case of hemi-central retinal artery occlusion presumably due to bifurcation of central retinal artery behind the lamina cribrosa
방법 : A 12-year-old girl with 6 months of history of decreased visual acuity visited our clinic. She was taking medication for vitamin D deficiency. She had a history of syncope and spinning sensation. Her tests performed by otolaryngologist were normal. On examinations her corrected visual acuity was 20/50 in each eye. Both anterior segments were normal. On fundus examinations superior and inferior hemi-trunks of central retinal artery were emerging separately in both eyes. We performed multifocal-ERG, visual field test, macular OCT and FAG
결과 : Both eyes showed decreased amplitude in multifocal-ERG, macular thinning in OCT and visual field constriction in Humphrey visual field(central 30-2). In FAG, inferior branch of retinal artery of right eye showed delayed filling
결론 : Unusual bifurcation of central retinal artery behind the lamina cribrosa coupled with the unique histological features of the retinal arterioles (hemi-trunks) may predispose to the development of ‘hemi-central retinal artery occlusion’ in young patients
