Comparative analysis of retinal damage at 7 or 30 days after Light Emitting Diode-induced phototoxicity (LIP). The number of L- or S-cones quantified in the predetermined fixed-size circular areas PCA, as well as the area lacking L- or S-cones (Damaged area) measured over flat-mounted retinas reveals that neither the area of the focal lesion nor the number of lost cones progress further between 7 and 30 days after LIP. Statistical analysis, T-test: * p = 0.579; † p = 0.253; ‡ p = 0.562; § p = 0.973.
