Blast wave exposure causes early and late visual deficits. (A) Bar graph of the electroretinogram (ERG) a_max over light intensity. An early decrease in the a_max recovers over time. (B) Bar graph of ERG b_max over light intensity. The b_max recovers by 14 days post-blast wave exposure then decreases again at 28 days post-blast wave exposure. (C) Bar graph of the oscillatory potential (OP) peak amplitude at each time point. The OPs are decreased at seven and 28 days post-blast wave exposure. (D) Photopic spatial threshold (visual acuity) is significantly decreased at three, 14 and 28 days post-blast wave exposure. *P <0.05, **P <0.01. Error bars represent SEM for each graph.
