Description
Summary:To report a case of unilateral prepapillary vascular loop along with peripheral third order retinal arteriolar tortuosity in the same eye, and to discuss potential diagnostic considerations. Color fundus pictures and wide-angle fluorescein angiography (FA) demonstrated a pre-papillary vascular loop and a region of retinal arteriolar tortuosity in third order arterioles superotemporally in the left eye. The examination and ancillary testing on the right eye were normal. The vascular abnormality in this case does not fit a pattern present in other disease states both hereditary or acquired. The patient's immediate family do not demonstrate a similar abnormality and the patient remains visually asymptomatic upon one-year follow-up.
