Associations of retinal oximetry in healthy young adults

Abstract

Purpose. To assess factors associated with retinal oximetry values in healthy young adults. Methods. Retinal oximetry readings were assessed using the oximetry module of the Vesselmap System in 100 eyes of 50 healthy subjects aged 18 to 58 years. Generalized estimating equation models were used to estimate the associations of candidate variables (age, sex, retinal capillary flow, HbA1c, triglyceride, total cholesterol, ocular perfusion pressure, and finger oxygen saturation [SO2]) with retinal oximetry measures (arteriolar SO2, venular SO2, and the arterio-venous [A-V] difference). Results. Of the candidate factors assessed, only age and finger SO2 were found to be significantly associated w..
