糖尿病性網膜症に対するpanretinal photocoagulationについて

Effect of panretinal photocoagulation for diabetic retinopathy

　糖尿病性増殖型網膜症23例（41眼）にpanretin-al photocoagulation（PRP）を行つた。

　乳頭新生血管の有無で，PRPの効果に著しい差があり，乳頭新生血管を伴わない症例では19眼中16眼（84％），乳頭新生血管を伴う症例では22眼中8眼（37％）に有効であつた。

　強い乳頭新生血管を伴う症例では，一時的には新生血管が減少するが，3カ月〜6カ月の経過で新生血管が再増殖する傾向があつた。また新生血管が再増殖し，硝子体出血を起こした5眼には冷凍凝固を併用したが，著効はみられなかつた。

Panretinal photocoagulation using argon laser was performed on 41 eyes (23 cases) with prolif-erative diabetic retinopathy and were followed up for 6 to 24 months after treatment. The cases included 19 eyes (13 cases) with retinal neovas-cularization and eyes (15 cases) with advanced proliferative retinopathy associated with optic disc neovascularization.

When judged in terms of visual acuity and fundus findings, panretinal photocoagulation was fairly effective (84%) for retinopathies without optic disc neovascularization. Lyes with optic disc neovascularization showed a tendency for recurrence 3 to 6 months after treatment.
