(18-P3-22) 糖尿病網膜症による血管新生緑内障が片眼にある24例の経過を,平均31か月検索した。他眼には,増殖前糖尿病網膜症が4眼(17%),増殖網膜症が20眼(83%),隅角新生血管が7眼(29%),網膜光凝固の既往が16眼(67%),白内障手術の既往が7眼(29%),硝子体手術の既往が3眼(13%)にあった。1眼を除いた全眼に,初回または追加治療として汎網膜光凝固が行われた。白内障手術を8眼に,硝子体手術を9眼に行った。これら他眼には,当初から隅角新生血管があった7眼中4眼に,経過中に新生血管緑内障が生じた。当初に隅角新生血管のない17眼には血管新生緑内障の発症はなかった。片眼に血管新生緑内障があっても,汎網膜光凝固を行うことで他眼の発症を回避できると解釈された。
We observed 24 diabetic patients with unilateral neovascular glaucoma for an average of 31 months. The fellow eyes showed, initially, preproliferative retinopathy 4 eyes (17%) , proliferative retinopathy 20 eyes (83%), angle neovascularization 7 eyes (29%) , history of retinal photocoagulation 16 eyes (67%) , history of cataract surgery 7 eyes (29%) and history of vitrectomy 3 eyes (13%) . All the fellow eyes but one were treated by primary or additional panretinal photocoagulation. Cataract surgery was performed on 8 eyes and vitrectomy on 9 eyes. Angle neovascularization was initially present in 7 eyes, of which neovascular glaucoma developed in 4 eyes during the follow up. No neovascular glaucoma developed in 17 eyes without prior angle neovascularization. The findings show that panretinal photocoagulation would prevent neovascular glaucoma even when the other eye is already affected.
