要約 目的:術中または術後に発症した脈絡膜出血への手術成績の検討。対象と方法:過去2年間に脈絡膜出血に対して手術を行った7例7眼につき,発症の危険因子,術後の網膜復位率,術後視力を検討した。年齢は49~89(平均70)歳であった。結果:脈絡膜出血の発症時期は,硝子体手術中2眼,硝子体手術後3眼,白内障手術中1眼,白内障手術後1眼であった。危険因子は,65歳以上の高齢6例,高血圧6例,糖尿病3眼,26mm以上の眼軸長1例,術中低眼圧2例であった。脈絡膜出血の除去は5眼で硝子体手術の強膜創を通じてのみ行い,2眼ではさらに強膜切開を加えた。7眼中6眼で網膜復位が得られた。最終視力は,術前に比べて5眼で維持または改善した。結論:術中生じた脈絡膜出血には積極的に手術を行うべきである。
Abstract. Purpose:To review the outcome of surgery for intra-or postoperative choroidal hemorrhage. Cases and Methods:Seven eyes of 7 cases received surgery for choroidal hemorrhage during a two-year period. Their ages ranged from 49 to 89 years,average 70 years. They were evaluated regarding risk factors,retinal reattachment,and visual outcome. Results:Choroidal hemorrhage developed during vitrectomy 2 eyes,after vitrectomy 3 eyes,and during or after cataract surgery 1 eye respectively. Following features appeared to be risk factors:age over 65 years 6 cases,systemic hypertension 6 cases,diabetes mellitus 3 cases,axial length over 26mm one case,and intraoperative ocular hypotony 2 cases. Choroidal hemorrhage was drained through the scleral port in 5 eyes. Additional sclerotomy had to be performed in the other 2 eyes. The retinal became reattached in 6 out of 7 eyes. Final visual acuity was the same or better than the preoperative value in 5 eyes. Conclusion:Surgical intervention is indicated for surgery-related choroidal hemorrhage.
