Typically afflicted children start life with poor vision, which worsens as more and
more photoreceptors die.

«This diversity will require
more research by tracking down the elusive
photoreceptor gene and examining the behavioural colour vision capabilities of other marsupials to confirm other species as trichromats.»
These findings have suggested the development stages at which to transplant cells — for instance,
photoreceptor cells need to be relatively
more mature than stem cells, according to Thomas Reh, who studies retinal development at the University of Washington.
Their group thinks they may need to treat
more of the retina and perhaps give patients another drug that slows
photoreceptor degeneration.
Only larger stimuli covering far
more than one cell's receptive field — the area where a bipolar cell collects
photoreceptor inputs — generated different signals across multiple channels.
We have identified over 1.2 million previously unknown genes represented in these samples, including
more than 782 new rhodopsin - like
photoreceptors.
More recently, her lab started working on the mechanisms that link oxidative stress and
photoreceptor loss and dysfunction, with the goal of identifying ways to target the underlying processes to prevent
photoreceptor and RPE loss in dry AMD.
This work, appearing March 23 in Science, also suggests that when the first ancestral primate inherited a new type of
photoreceptor more than 40 million years ago, it probably experienced immediate color enhancement, which may have allowed this trait to spread quickly.
Because this material appears to be
more abundant in affected Swedish vallhund dogs compared to other forms of PRA with primary
photoreceptor death or compared to the normal aging canine retinas, we suspect that the autofluorescent material is intimately associated with the disease - causing gene mutation.
