B, C Representative Iba1 stainings of retinal flat mounts detecting microglia/macrophages in laser spots 3 days after laser coagulation in C57BL6/J controls (B) and Ifnar1-/- (C) mice. Scale bar: 20 µm.D Quantification of amoeboid-shaped mononuclear phagocytes in laser spots. Values show mean ± SD. (n = 11-12 retinas; unpaired Student's t-test: ***p = 0.0004).E Quantification of immune cell morphology in laser spots using a grid image analysis system. Values show mean ± SD. (n = 42-62 cells; unpaired Student's t-test: ***p < 0.0001).
