pigmentation
• the fundus appears grainy, and there is rapid photoreceptor degeneration and thinning of the retinal pigment epithelium, with a slightly thinned outer nuclear layer at 14 days of age and only 3 to 4 rows of photoreceptor nuclei at 21 days of age
• rhodopsin is mislocalized to the soma of photoreceptor cells

• rhodopsin is mislocalized to the soma of photoreceptor cells
• although light adapted (cone) ERG readings are normal at 21 days of age, dark-adapted ERG shows severely diminished rod function
