Figure 3. The effect of blue light exposure on the cell death of the retina in C57BL/6J mice. C57BL/6 mice were exposed to different intensities of blue light (10,000, 15,000, and 20,000 lux) for 5 days, and terminal-deoxynucleotidyl transferase 24 (TdT)-mediated nick-end labeling (TUNEL) assay was used to evaluate the cell death of the mouse retinas (TUNEL: red fluorescence, 2-(4-Amidinophenyl)-6-indolecarbamidine dihydrochloride [DAPI]: blue fluorescence). INL: inner nuclear layer, ONL: outer nuclear layer, GCL: ganglion cell layer.
