傍乳頭網膜血管腫の1症例

A case of juxtapapillary retinal hemangioma

　45歳，男性の左眼乳頭耳側下方に隣接して，約1／2乳頭径大の赤澄色のendo—phyticな網膜血管腫を認め，腫瘍の周囲には新生血管網を認めた。3年間の経過観察で，腫瘍の拡大はなく，3年目に新生血管網由来と考えられる硝子体出血をきたしたため，新生血管に対して直接的光凝固を施行した。その後，硝子体出血の再発および腫瘍の増大なく経過している。

A 45-year-old male manifested an endophyticcapillary angioma adjacent to and temporal to the optic nerve head in his left eye. The angioma was 1/2 DD in size and was surrounded by neovascular membrane. No treatment was performed because of the location of the angioma, normal visual acuity and little tendency for enlargement over a period of 2 years. Vitreous hemorrhage developed 2 years after, apparently originating from the neovascualar membrane. Direct photocoagulation applied to the neovascular membrane prevented recurrence of vitreous hemorrhage.
