What is Clinical and Morphologic Characteristics of Perivenular Fernlike Leakage on Ultrawide-field Fluorescein Angiography about?
## Purpose: To analyze the spectrum of the perivenular fernlike leakage on ultrawide-field fluorescein angiography (UWFA) and discuss its potential implications in the current understanding of the retinal venous outflow. Design: Retrospective, observational case series. Participants: Eyes presenting with fernlike patterns of dye leakage on UWFA were included in this study. Methods: Analysis of the clinical characteristics and multimodal imaging findings using UWFA and wideangle swept-source OCT-angiography (SS-OCTA). Main Outcome Measures: The disease spectrum, anatomic origin, and clinical implications of this fernlike leakage. Results: Multimodal retinal images from 40 eyes of 29 patients with fernlike leakage on UWFA were studied. The underlying etiologies included a wide range of inflammatory disorders, including pars planitis (18 eyes) and central retinal vein occlusion (2 eyes). On UWFA, the fernlike leakage originated from the retinal capillaries and venules directly adjacent to the veins and spared the periarterial zone. This perivenular fernlike leakage involved the far periphery in all cases and progressed more diffusely and centripetally in cases with more severe intraoc
