Opsin- and S-antigen-like immunoreactions in photoreceptors of the tree shrew retina.

abstract：Purpose:RPE65-associated Leber congenital amaurosis (RPE65-LCA) is a progressive severe retinal dystrophy with early profound dysfunction of rod photoreceptors followed by progressive cone photoreceptor degeneration. We aim to provide detailed information about how cone dysfunction affects color discrimination. Method...
