Prevalence of Prepapillary Vascular Loop
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2015, Vol 3, Issue 2
Abstract
The purpose of the study was to evaluate the prevalence of a prepapillary vascular loop. We retrospectively analyzed 7,856 patients at our hospital for health screening during the 1-year period. All patients, including 4,421 men and 3,435 women, were analyzed using fundus photographs. The overall prevalence of prepapillary vascular loop was found to be 0.115% (9/7,856). Out of nine patients with prepapillary vascular loops, two were men (2/4,421; 0.045%) and seven were women (7/3,435; 0.204%). Four patients had arterial loops, while another four had venous loops. Seven loops were located in the upper optic disc region, while one was located in the lower region. In one patient, multiple loops were detected, and one patient had a prepapillary vascular loop in both eyes. Among the patients who underwent health screening, the prevalence of prepapillary vascular loop was found to be 0.115%. These results may aid in explaining clinically rare conditions.
