Diabetic corneal epithelial cells increase the generation of intracellular reactive oxygen species (ROS). Representative images were observed and captured after 24 h of culture (a), and the ROS Brite intensity was analyzed by ImageJ software (b). n = 4 independent experiments. In cultured stratified human primary CEC (hCEC), ROS production was significantly increased (c). n = 3 or 6 independent experiments. Mean ± S.D. **P < 0.01
