網膜血管腫による網膜・硝子体病変への硝子体手術

Vitreous surgery for vitreoretinal changes in retinal hemangioma

　後天性網膜血管腫は硝子体手術を行わずとも比較的予後が良好とされているが，今回，硝子体手術を必要とした網膜・硝子体病変を伴う後天性網膜血管腫の2症例を経験した。症例1は92歳男性で，白内障と硝子体出血を認めたため，経毛様体扁平部前嚢温存超音波水晶体乳化吸引術，硝子体手術および光凝固を行った。血管腫は瘢痕化し，術後1年においても再発はみられない。症例2は49歳女性で，増殖組織を伴った強い硝子体牽引により進行性の牽引性網膜剥離を認めた。硝子体手術に加えて光凝固，冷凍凝固および強膜バックリングを施行して血管腫の癌痕化と，網膜の復位を得た。術後10か月においても再発はみられない。後天性血管腫の中には，積極的な硝子体手術が要求される症例が存在する。

We observed two cases of acquired retinal hemangioma in patients who needed vitreous surgery for vitreoretinal changes.

Case 1: A 92-year-old male presented with cataract and massive vitreous hemorrhage. We performed pars plana phacoemulsification preserving an intact anterior capsule, vitreous surgery, endophotocoagula-tion, and transpapillary photocoagulation. This therapeutic modality was effective in destroying the heman-gioma. One year after the operation, there has been no recurrence.

Case 2: A 49-year-old female presented with progressive traction retinal detachment caused by prolifer-ative changes. We performed vitreous surgery, endophotocoagulation, transscleral cryoapplication, and scleral buckling. This therapy was effective in destroying the hemangioma and stopping the retinal detach-ment. Ten months after the operation, there has been no recurrence.
