要約 目的:高度硝子体出血に対して行った硝子体手術の結果の報告。症例:過去5年間の自験例24例24眼を検索した。外傷や糖尿病など,原因が推定できる症例は除外した。男性14例,女性10例であり,年齢は34~88歳(平均63歳)であった。発症から手術までの期間は1~110日,(平均25日)であり,19例(79%)では発症から30日以内に手術を行った。結果:14例(58%)で1.0以上の最終視力が得られた。再手術を必要とする重大な合併症はなかった。手術中に判明した原因疾患は,網膜静脈分枝閉塞症9例,網膜裂孔7例,加齢黄斑変性症2例,裂孔原性網膜剝離2例,網膜細動脈瘤2例,網膜中心静脈閉塞症2例であった。結論:原因が同定できない高度硝子体出血には早期に硝子体手術を行うべきである。
Abstract. Purpose:To report the outcome of early vitrectomy for idiopathic vitreous hemorrhage. Cases:This retrospective study was made on 24 eyes of 24 patients who received vitrectomy during the past 5 years. The series comprised 14 males and 10 females. The ages ranged from 34 to 88 years,average 63 years. The interval from onset to surgery ranged from 1 to 110 days,average 25 days. Surgery was performed within 30 days after onset in 19 cases(79%). Results:Final visual acuity of 1.0 or over was obtained in 14 cases(58%). Severe intra- or postoperative complications were absent throughout. Causes of vitreous hemorrhage were identified in all cases during surgery. They included branch retinal vein occlusion 9 eyes,retinal break 7 eyes,and 2 eyes each of rhegmatogenous retinal detachment,age-related macular degeneration and retinal macroaneurysm. Conclusion:Early vitrectomy is indicated for dense vitreous hemorrhage of unidentified origin.
