The effect of panretinal photocoagulation (PRP) on mean circulation time (MCT) was investigated in a main nasal superior artery and vein of 13 eyes with proliferative diabetic retinopathy, using fluorescein video angiography and an image analysis system. MCT before photocoagulation averaged 5.67 +/- 1.40 seconds. Two weeks after PRP, MCT averaged 4.29 +/- 0.89 sec., one month after, 4.29 +/- 0.88 sec., three months after, 4.03 +/- 0.86 sec., and six months after, 3.61 +/- 0.31 sec. The MCTs after PRP were shorter than MCT before PRP (p less than 0.01). These results suggest that MCTs in proliferative diabetic retinopathy shortened soon after PRP.
利用荧光素视频血管造影术和图像分析系统，在13只患有增殖性糖尿病视网膜病变眼睛的鼻上主血管中，研究了全视网膜光凝术（PRP）对平均循环时间（MCT）的影响。光凝术前MCT平均为5.67±1.40秒。PRP术后两周，MCT平均为4.29±0.89秒，术后1个月为4.29±0.88秒，术后3个月为4.03±0.86秒，术后6个月为3.61±0.31秒。PRP术后的MCT比术前短（p<0.01）。这些结果表明，增殖性糖尿病视网膜病变的MCT在PRP术后很快缩短。
