Sexual Dimorphism of the Adult Human Retina Assessed by Optical Coherence Tomography

Abstract

In this work, we imaged the retina of healthy age-matched female and male subjects with optical coherence tomography to assess the existence of localised sex-related differences in the retina. Texture analysis revealed statistically significant differences spread over the different layers of the neuroretina, particularly at the ganglion cell, inner plexiform and inner nuclear layers, and also spread in the macula. These results suggest that sexual dimorphism is expressed in the retina at the microstructural level.
