Changes in Relative Position of Choroidal Versus Retinal Vessels in Preterm Infants.

ABSTRACT: Purpose:The purpose of this study was to characterize a novel finding that relative positions of choroidal and retinal vessels change over time in preterm infants and to identify factors associated with this finding using quantitative analysis. Methods:Fundus images were obtained prospectively through a retinopathy of prematurity (ROP) cohort study. Images were excluded if choroidal vessels could not be identified. Changes in relative position of characteristic choroidal landmarks with respect to retinal vessels between two time points 5 to 7 weeks apart were measured. Univariate and multivariate regression analyses were performed to identify associated factors with the amount of change. Results:The discovery and replication cohorts included 45 and 58 patients, respectively. Ninety-two of
