Correlation of retinopathy with leukoaraiosis in patients with anterior circulation infarcts

Although retinal and cerebral microvessels share similar embryological, anatomical and physiological characteristics, the correlation between retinopathy and leukoaraiosis (LA), a type of brain microvascular disease, is unclear. In the present study, the sample included 213 patients admitted to the department of neurology from January 2012 through October 2012. MRI and retinal photography were performed within 48 hours of hospitalization, and patient demographics, comorbidities, preadmission medications and laboratory data were collected. MRI images were used to divide the patients into LA and non-LA groups. Using multivariate binary logistic regression, the effects of retinopathy on LA were investigated. Of the 213 patients enrolled, 168 were included in this study (LA, n = 108; non-LA, n = 60). Hypertension, coronary heart disease and carotid artery plaque were more common in the LA group, and these patients showed higher blood levels of C-reactive protein, homocysteine and triglycerides. The incidence of retinopathy was significantly increased in the LA group compared with the non-LA group, and there was a significant correlation between the severity of LA and incidence of retinopathy. Retinopathy is an independent risk factor for LA and can significantly increase the risk of LA when combined with age, coronary heart disease, C-reactive protein, carotid artery plaque or systolic pressure. Taken together, retinopathy is associated with LA in patients with anterior circulation infarcts. Retinopathy is an independent risk factor for LA and an increase the risk of LA, and thus facilitating the evaluation of LA. (C) 2016 Published by Elsevier Ltd.
