N normal phenotype
vision/eye
• photoreceptors show a slow and progressive loss of 3 or 4 nuclear layers by P160
• however, photoreceptor development is normal
• slow and progressive photoreceptor degeneration by P160
• ERG shows that light-evoked response is progressively reduced in retinas by P160
• cones exhibit a greater functional loss than rods
• however, no changes in rod or cone responses are seen at P24
• rod responses progressively decline with age, with maximal rod responses reduced by 82% at P160
• cone responses are reduced by 92% at P160
• progressive loss of vision

nervous system
• slow and progressive photoreceptor degeneration by P160
