[Effect of photocoagulation on retinal mean circulation time in proliferative diabetic retinopathy by use of fluorescein video angiography and image analysis system]. 1991

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.
