Figure 2. Decrease RPE phagocytosis after light injury in vivo.

A: Dysfunction of RPE phagocytosis in vivo was evaluated by measuring the thickness of rhodopsin labelled POS. In normal retina, the average thickness of POS; B-D: Light injury induced a dose dependent accumulation of POS in mice retina. ^aP<0.05, ^bP<0.01, ^cP<0.001.
