We measured retinal vessel diameter before and after panretinal photocoagulation in 59 eyes with diabetic retinopathy and moderate to severe optic disk neovascularization. Treatment significantly reduced mean arteriolar and venular diameter. The diameter of the retinal arterioles after treatment correlated significantly with the amount of regression in disk neovascularization. Eyes with large diameter vessels after treatment usually had little or no regression of proliferative retinopathy, whereas regression was more frequently seen in eyes with smaller diameter vessels after treatment.
我们测量了59例患有糖尿病性视网膜病变且伴有中度至重度视盘新生血管形成的患者，在全视网膜光凝治疗前后的视网膜血管直径。治疗显著降低了平均小动脉和小静脉直径。治疗后视网膜小动脉的直径与视盘新生血管的消退量显著相关。治疗后血管直径大的眼睛，增生性视网膜病变通常很少或没有消退，而治疗后血管直径小的眼睛更常出现消退。
