vision/eye
• attenuated retinal vessels at 5 months of age
|
• by 5 months of age there is a loss of 20-30% of photoreceptors and rapid loss after that with no photoreceptors found at 7 months of age
|
• homozygotes develop late onset retinal degeneration with rapid progression, which leads to retinal detachment
|
• presenting at approximately 7 months of age
|
• dark-adapted ERG responses begin to decrease after 4 months of age while the loss of light-adapted ERG responses is slightly delayed beyond that, but by 8 months there are no ERG responses
|
• although the cone ERG response are approximately normal at 5 months of age there is no rod or cone ERG response at 8 months of age
|
• at 4 months of age the rod ERG is near normal, but at 5 months of age there is a lower ERG a-wave and almost normal b-wave, and at 8 months of age there is no ERG a-wave or b-wave
|
• no cone or rod ERG waveform is detectable at 8 months of age
|
nervous system
• by 5 months of age there is a loss of 20-30% of photoreceptors and rapid loss after that with no photoreceptors found at 7 months of age
|
cardiovascular system
• attenuated retinal vessels at 5 months of age
