简介：目的：观察糖尿病视网膜病变（diabeticretinopathy,DR）患者行全视网膜光凝（panretinalphotocoagulation,PRP）后服药前及服药2mo后患眼的全视野视网膜电图（fullfieldelectroretinogram,ERG）变化,探讨递法明片对DR暗适应功能的保护作用。方法：选择在我医院就诊的重度非增殖性糖尿病视网膜病变（nonproliferativediabeticretinopathy,NPDR）患者55例55眼,随机分为治疗组和对照组。两组均行全视网膜光凝,治疗组光凝后口服递法明片,对照组口服维生素B1片2次/d,10mg/次。PRP后服药前及服药2mo后行全视野视网膜电图检查,观察其暗视视杆反应的变化并进行统计学处理。结果：两组患者服药前及服药2mo后,暗视视杆反应bT值组内及组间比较差异均无统计学意义（P〉0.05）;治疗组bA值服药2mo后与服药前相比振幅升高,差异有统计学意义（P〈0.05）,与对照组相比治疗组振幅升高较大,差异有统计学意义（P〈0.05）。结论：递法明片可减轻PRP治疗对视网膜的损害,改善患者的暗适应功能。
