Abstract
We examined improvement of ocular ischemia in patients with carotid endarterectomy (CEA) with chorioretinal blood flow measurements using laser speckle flowgraphy (LSFG). LSFG allowed the quantitative measurement of chorioretinal blood flow. Five CEA patients, 4 men and 1 women ranging in age from 59 to 79 years, with carotid stenosis were examined. Three patients were symptomatic, and 2 patients were asymptomatic. The ratio of carotid stenosis was 68% to 98%. None of the patients presented delayed arm-to-retina circulation by fluorescein angiography. Four of 5 patients presented a mean increase in chorioretinal blood flow. The mean increase ratio of blood flow was 7.84%. LSFG was useful to evaluate peripheral blood flow in CEA patients and revealed that CEA may improve ocular ischemia.
