Figure Lengend Snippet: (A–E) Hypertonic buffer robustly outperforms untreated and vector-treated eyes in light-adapted ERGs. Cone-dependent retina function was measured using two separate light-adapted ERG assays—the 5 Hz flicker (A) and 3.0 flash (B) . ERG amplitudes are shown from 1-month post injection (MPI) to 5 MPI for vector-treated, hypertonic buffer-injected, and untreated eyes in Rs1 -KO mice, and representative ERG traces at 5 MPI are illustrated. In response to both light-adapted assays, hypertonic buffer-injected eyes showed higher amplitudes than untreated and vector-treated eyes to 5 MPI (A) . The combined rod-cone function was measured by the 3.0 cd·s/m 2 standard combined response (SCR) under dark-adapted conditions (C) . At 1, 3, and 5-MPI, there was no difference between vector-treated, hypertonic buffer-injected, or untreated eyes. Isolated rod function was measured using 0.01 cd·s/m 2 dim flash after dark adaptation (D) . There was no persistent significant difference between hypertonic buffer-injected, isotonic buffer-injected, or untreated eyes in rod dominant ERG settings.
