Report of Cases.
—This 33-year-old woman with mild myopia was evaluated at University Hospitals of Cleveland for a change in the prescription of her eyeglasses. Her best corrected acuity was 20/20 in each eye. Results of an external and anterior segment examination were normal. A fundus examination disclosed prepapillary vascular loops in each eye (Figs 1 and 2). On informing the patient of the presence of the prepapillary loops, she reported that her mother had similar findings.
