简介：
Overview
This article presents a method for recording light-evoked electrical responses of the retinal pigment epithelium (RPE) in mice using the DC-ERG technique. This non-invasive method allows for the evaluation of RPE function, monitoring age-related changes, disease progression, and assessing pharmacological interventions.
