The effect of panretinal laser scatter treatment on visual fields, visual acuity and subjective complaints was assessed in 11 patients with severe nonproliferative or early proliferative diabetic retinopathy. Patients were prospectively examined before and after panretinal treatment using automated static threshold perimetry with program 30-2 on the Humphrey perimeter, and they were interviewed. Visual field sensitivity was often depressed even before treatment with mean MD -4.3 (-1, -11.6) dB, but was significantly lower (p < 0.01, ANOVA) 2 weeks after treatment with mean MD -8.6 dB. Visual fields remained stable 4 months later. Treatment increased the number of eyes with visual fields as defined by abnormal MD values at the p < 0.05 level from 8 to 16 among the 17 treated. In spite of considerable impairment of visual fields after treatment, subjective problems were small and the visual field impairment seemed to have little influence on everyday life.
对11例患有严重非增殖性或早期增殖性糖尿病视网膜病变的患者评估了全视网膜激光光凝治疗对视野、视力和主观症状的影响。使用Humphrey视野计上的程序30-2对患者在全视网膜治疗前后进行前瞻性自动静态阈值视野检查，并对他们进行访谈。即使在治疗前视野敏感度也常降低，平均MD为-4.3（-1，-11.6）dB，但在治疗2周后显著更低（p<0.01，方差分析），平均MD为-8.6dB。4个月后视野保持稳定。在17例接受治疗的患者中，治疗使MD值异常所定义的视野异常眼数在p<0.05水平从8只增加到16只。尽管治疗后视野有相当程度的损害，但主观问题较小，且视野损害似乎对日常生活影响不大。
