われわれは過去6年間に10例のperipheral exudative hemorrhagic choriOretinopathy (PEHCR)を経験した。本症は,黄斑外の網膜下または色素上皮下に滲出や出血が生じる高齢者の疾患であり,加齢黄斑変性症に類似する。男性7例,女性3例であり,すべて片眼性であった。年齢は60歳から80歳,平均71歳であった。7眼では硝子体出血が初発症状であり,硝子体手術後に診断が確定した。病巣は4眼で耳側周辺部にあり,4眼に加齢黄斑変性が併発していた。新生血管は,フルオレセイン螢光造影では証明できず,インドシアニングリーン螢光造影で2眼にこれが検出された。本症が硝子体出血の原因になりうることが留意されるべきである。
We observed ten cases of peripheral exudative hemorrhagic chorioretinopathy (PEHCR) during the past six years. This disease is characterized by exudation and hemorrhage in the subretinal space or posterior to the retinal pigment epithelium in extramacular area. It is prone to involve age persons and may simulate age-related macular degeneration. The present series comprised 7 males and 3 females. Only one eye was involved in all the cases. The ages ranged from 60 to 80 years, average 71 years. Vitreous hemorrhage was the initial presenting symptom and the PEHCR was identified after vitreous surgery. The lesion was located temporal to the macula in 4 eyes. Age-related macular degeneration was also present in 4 eyes. Neovascularization was identified only by indocyanine green angiography in 2 eyes. PEHCR may be one of the causative lesions in vitreous hemorrhage of unidentified nature.
