Abstract

We present here a study of blood oxygen saturation (sO2) in the parafoveal region from healthy subjects using visible light optical coherence tomography. Sixteen eyes of the normal subjects were analyzed. The sO2 of arterioles was significantly higher than the venules’ (92.1 ± 7.1 (vol %) for arterioles, 48.4 ± 5.0 (vol %) for venules, p<0.001), indicating that VIS-OCT can be a powerful tool to investigate the retinal sO2 in parafoveal micro-vessels in pathological conditions.
