Longitudinal changes in the thickness of the retinal sublayers on OCT in P23H (closed circle) and SD (open circle) rats.

<p>A, changes in the thickness of the retinal sublayer A, which consists of the retinal nerve fiber layer, retinal ganglion cell layer, the inner plexiform layer, and the INL. B, changes in thickness of retinal sublayer B, which consists of the OPL and the ONL. C, changes in thickness of retinal sublayer C, which consists of the IS/OS layer. D, changes in thickness of the retinal sublayer D, which consists of the RPE and choroid. Tukey’s <i>t</i>-test was performed for statistical comparisons between the two groups. Significance level: **, <i>P</i> < 0.01; ***, <i>P</i> < 0.001). Values are indicated by mean ± standard error.
