Effects of near-infrared light on retinal layer thickness. Rotenone induced a significant decrease in the RNFL + GCL and IPL thickness. NIL treatments prevented degeneration in the RNFL+GCL in a dose–response manner. Rot, Rotenone; NIL 1 = rotenone + 10.8 J/cm2 NIL postinjection; NIL 2 = rotenone + 21.6 J/cm2 postinjection; NIL 3 = rotenone + 10.8 J/cm2 preinjection + 10.8 J/cm2 postinjection. Significant difference compared with control at *p < 0.05; significant difference compared with control at **p < 0.01.
