RetGen

Now, investigators from the University of Pennsylvania and Cornell University provide evidence for retinal injury caused by moderate light exposure in dogs with a mutation in the rhodopsin gene. Since the blindness in these dogs mimics that observed in human RP caused by mutations in the rhodopsin gene, the investigators strongly recommend limiting excess light exposure in these patients.
