Abstract

The effect of panretinal photocoagulation (PRP) on mean circulation time (MCT) and the diameter of the retinal vein was investigated in 12 eyes with proliferative diabetic retinopathy using fluorescein video angiography and an image analysis system. MCT before photocoagulation averaged 5.67±1.47 seconds, and 3 months after PRP it averaged 4.09±0.87 seconds, a significant difference (p< 0.01). The diameter of the retinal vein was narrower after PRP than before PRP (90.5±4.3%) (p< 0.01). These results suggest that PRP improves retinal circulation in eyes with proliferative diabetic retinopathy.
