要約 目的:過去2年間の増殖糖尿病網膜症に対する硝子体手術の成績の報告。対象と方法:2008年までの2年間に20ゲージ硝子体手術を行った増殖糖尿病網膜症70例76眼を対象とした。男性44眼,女性32眼で,年齢は35~78歳(平均59歳)である。全例がインスリン非依存性糖尿病であり,術後6~30か月(平均11か月)の経過を追った。視力はlogMARで評価し,0.2以上の変化を改善または悪化とした。結果:術後視力は改善55眼(72%),不変19眼(25%),悪化2眼(3%)で,平均視力は有意に改善した(p=0.0005)。硝子体再手術は3眼に行われ,これを含めた解剖学的な手術成功率は98.7%であった。年齢が若いほど術後視力が良好であった(p=0.01)。結論:増殖糖尿病網膜症に対する20ゲージ硝子体手術で,視力の改善または維持が97%の症例で得られた。
Abstract. Purpose:To report the outcome of vitreous surgery for proliferative diabetic retinopathy in the past 2 years. Cases and Method:This retrospective study was made on 76 eyes of 70 cases who received 20-gauge vitrectomy in 2007 and 2008. All had non-insulin dependent diabetic retinopathy. The series comprised 44 male and 32 female eyes. The age ranged from 35 to 78 years,average 59 years. Cases were followed up for 6 to 30 months,average 11 months. Results:Visual acuity improved in 55 eyes(72%),remained unchanged in 19 eyes(25%),and deteriorated in 2 eyes(3%). Averaged visual acuity showed significant improvement(p=0.0005). Repeat vitreous surgery was performed in 3 eyes(4%). Anatomical improvement was obtained in 98.7% of eyes. Visual outcome was better in younger patients(p=0.01). Conclusion:Visual acuity improved or was maintained in 97% of eyes after 20G vitreous surgery for proliferative diabetic retinopathy.
