Fig 6. Electron microscopic findings of the photoreceptor inner and outer segment layer and the retinal pigment epithelial cells (RPE) of C57BL/6J (A) and Rdh5-/- (B) mice at PM4, and C57BL/6J (C) and Rdh5-/- (D) mice at PM6, respectively.
The arrows indicate low electron-density vacuoles in the RPE of Rdh5-/- mice. Bars indicate 10 μm.
