三井記念病院眼科および東大眼科糖尿病専門外来における糖尿病性網膜症のうち,黄斑浮腫を呈した51症例59眼に対して格子状網膜光凝固を施行し,視力検査,静的中心視野検査,眼底検査,螢光眼底検査にて検討を加えた.
術後2段階以上の視力改善は22眼(37%)にみられ,33眼(56%)は不変で,悪化は4眼(7%)であった.螢光眼底所見において,60%に改善がみられ,静的中心視野における悪化は3%であった.
術後の視力改善は,術前における視力,黄斑部の浮腫,硬性白斑の程度に左右され,全身的には,高血圧の既往のないものに良好であった.また,術後の抗炎症剤の併用が有用であることが示唆された.
We treated a consecutive series of 59 diabetic eyes with diffuse macular edema by means of grid pattern argon green or krypton red laser photocoagulation.
Visual acuity improved by 2 lines or more in 22 eyes (37%), remained unchanged in 33 (56%) and turned worse in 4 (7%). No central scotoma couldbe detected in all the 59 eyes.
Poor visual acuity due to severe edema and exudate in the macula before the treatment was a risk factor for poor prognosis after the treatment. Systemic hypertension was another poor prognostic sign for visual improvement. Systemic administra-tion of anti-inflammatory drugs after photocoa-gulation appeared to be effective in alleviating diffuse diabetic macular edema.
