All values are expressed in μm (mean±SD).
*Statistically significant changes compared with controls.
CHM, choroideremia; EZ-RPE, ellipsoid zone–retinal pigment epithelium layer; GCL, ganglion cell layer; INL, inner nuclear layer; IPL, inner plexiform layer; ONL, outer nuclear layer; OPL, outer plexiform layer.
