増殖糖尿病網膜症に伴う血管新生緑内障に対する手術治療の長期成績

Long-term outcome of surgery for neovascular glaucoma secondary to proliferative diabetic retinopathy

　過去5年間に，増殖糖尿病網膜症に併発した血管新生緑内障10例13眼に対して手術を行った。いずれも初回手術であり，硝子体手術と水晶体切除を基本とし，症例に応じて毛様体濾過手術やcyclophotocoaguiation ab externo，線維柱帯切除術を併用した。手術回数は1回から6回，平均3.3回であり，最終手術から9ないし50か月，平均19.1か月の問経過を観察した。11眼（85％）で眼圧は正常化した。0.1以上の視力が6眼（46％）で得られ，2眼が0となった。

We reviewed 13 eyes of 10 patients with proliferative diabetic retinopathy which underwent surgery for neovascular glauoma during the past 5 years. The initial surgery comprised vitrectomy with lensectomy. Pars plana filtering procedure or cylophtocoagulation ab externo or trabeculectomy was additionally performed depending on the clinical features. Surgery was repeated one to 6 times, average 3.3 times. Cases were followed up for 9 to 50 months after the last surgery, average 19.1 months. The intraocular pressure was normalized in 11 eyes (95%). The final visual acuity was 0.1 or better in 6 eyes (46%). Two eyes became blind.
