No Difference Between Age-Matched Male and Female C57BL/6J Mice in Photopic and Scotopic Electroretinogram a- and b-Wave Amplitudes or in Peak Diurnal Outer Segment Phagocytosis by the Retinal Pigment Epithelium.

Mice provide informative models of enormous utility for eye research. Sex as biological variable must be considered when conducting studies exploring mouse models. To determine if sex confounds neural retina or retinal pigment epithelium (RPE) activity in wild-type C57BL/6J mice, we compared male and female mice with respect to retinal light response and RPE phagocytosis.
