Molecular features and neuroretinal function.

<p><b>(A)</b> Retinal VEGF was measured by qPCR at intervals (0,1,2,3,5 and 8 days) following exposure to hyperoxia (n = 4–7 per group. <b>(B)</b> GFAP expression measured by qPCR (n = 5–7 per group). <b>(C)</b> Representative images of GFAP immunostaining in retinal sections from mice after the conventional and the accelerated protocol. <b>(C)</b> and <b>(C’)</b> show the variability within the conventional OIR group. <b>(D to G)</b> Electroretinographic (ERG) a-wave and b-wave amplitudes in scotopic conditions were measured at P26-27 <b>(D, E)</b> and at P60 <b>(F, G)</b> in mice previously exposed to the conventional and accelerated OIR protocols, and in age-matched non-OIR controls (n = 4–13 per group). Data are expressed as means ± SEM.
