Figure 8. Assessment of retinal wholemount vaso-obliteration and neovascularization. A: Retinal wholemounts in RA mice (n = 4) and OIR mice (n = 4). The white arrow denotes activated microglia. B: Quantification of vaso-obliteration and neovascularization in retinal wholemounts. RA = room air; OIR = oxygen-induced ischemic retinopathy; P = postnatal day age; VO = vaso-obliteration; NV = neovascularization. At P19, four RA mice and four OIR mice were examined; at P24, three RA mice and four OIR mice; at P32, four RA mice and four OIR mice; and at P47, four RA mice and five OIR mice.
