Ultra-Widefield Imaging of Presumed Vitreous Base-Associated Vasculopathy: Assessment of Peripheral Retinal Hemorrhages and Microaneurysms.

Abstract

Purpose: To describe cases of asymptomatic peripheral retinal hemorrhage attributed to presumed vitreous base traction seen on ultra-widefield (UWF) imaging. Methods: This retrospective consecutive series comprised asymptomatic patients with peripheral retinal hemorrhages, microaneurysms, or both. Imaging included UWF fundus photography, fundus autofluorescence, fluorescein angiography (FA), optical coherence tomography (OCT), or a combination. Results: The series included 9 adult patients. The findings were observed on a routine eye examination or as an incidental finding in the contralateral eye of patients presenting with a retinal break or detachment. On UWF imaging, the distinguishing features of the peripheral retinal hemorrhages and microaneurysms presumably caused by vitreous base traction were their pinpoint shape and location at the vitreous base, in particular in the far temporal and superior retinal periphery. UWF FA showed punctate hyperfluorescent spots with no leakage. OCT showed signs of evolving posterior vitreous detachment. Management was limited to observation; with time, the microaneurysms were stable and the hemorrhages resolved. Conclusions: UWF imaging has led to the identification of presumed vitreous base vasculopathy. After a targeted workup is unrevealing, observation is appropriate.
