糖尿病網膜症に対する汎網膜光凝固の長期予後—その2．眼合併症

Long-term follow-up in patients with diabetic retinopathy following panretinal photocoagulation. Part 2. Ocular complications

　汎網膜光凝固後の糖尿病網膜症眼の眼合併症を検討した。対象は43例73眼で，増殖前網膜症19例25眼，増殖網膜症31例48眼，年齢30〜76歳（平均51歳），観察期間60〜150か月（平均7年9か月）であった。増殖前網膜症で光凝固後に網膜新生血管の発現をみたのは25眼中9眼であった。硝子体出血は増殖前網膜症25眼中4眼，増殖網膜症48眼中33眼に発生した。光凝固後の初回硝子体出血は48.7％が6か月以内，73.0％が2年以内に生じた。牽引性網膜剥離は増殖前網膜症で1眼，増殖網膜症で10眼にみられ，光凝固前からの新生血管に線維増殖を伴うものに多く起こった。虹彩ルベオーシスは増殖網膜症の3眼に発生したが，血管新生緑内障はみられなかった。

We evaluated the ocular complications after panretinal photocoagulation (PRP) for diabetic retinopathy in 73 eyes, 43 patients. The series com-prised preproliferative diabetic retinopathy 25 eyes and proliferative one 48 eyes. The ages ranged from 30 to 76 years, mean 51 years. The follow-up period ranged from 60 to 150 months, mean 93 months. Retinal neovascularization developed in 9 of 25 eyes with preproliferative retinopathy. Vitreous hemorrhage occurred in 4 eyes with preprolifer-ative retinopathy and in 33 eyes with proliferative one. First vitreous hemorrhage after PRP occurred within 6 months in 49% of these 37 eyes and within 2 years in 73%. Traction retinal detachment devel-oped in one eye with preproliferative retinopathy and in 10 eyes with proliferative one. It was prone to develop in eyes manifesting fibrovascular mem-brane before PRP. Rubeosis iridis without glau-coma developed in 3 eyes with proliferative retinopathy.
