Abstract

To investigate retinal hemodynamics in branch retinal vein occlusion(BRVO), we measured retinal circulation times using scanning laser ophthalmoscope(SLO) and studied the relationships with clinical findings. Arm-retina time(ART) and arteriovenous passage time(AVP) were measured in 35 eyes of 35 patients. Mean ART was 13.05 sec. ART showed no difference with sex and systemic diseases, but increased withage. AVP of occluded branch was much longer than those of other branches. AVP was delayed according to the size of capillary nonperfusion area, but showed no difference according to the duration of disease and macular edema. These results suggest that SLO is an useful method for studying retinal hemodynamics in BRVO.
