Collateral Vessel Development in Central and Branch Retinal Vein Occlusions Are Associated With Worse Visual and Anatomic Outcomes.

ABSTRACT:

Purpose

The purpose of this study was to investigate the effects of the extension of collateral vessels on the outcomes of eyes affected by central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO).

Methods

The study was designed as a cross-sectional case series. Patients affected by CRVO and BRVO were progressively recruited, along with an age- and sex-matched control group of healthy subjects. Structural optical coherence tomography (OCT) and OCT angiography (OCTA; 4.5 × 4.5 mm and 9.0 × 9.0 mm acquisitions) were performed on all participants in order to assess the relationship between the presence of collateral vessels and final anatomical outcomes - central macular thickness (CMT), foveal avascular zone - and functional outcomes - best corrected visu
