Background: Canine progressive retinal atrophies are a group of hereditary retinal degenerations in dogs characterised by depletion of photoreceptor cells in the retina, which ultimately leads to blindness. PRA in the Lhasa Apso (LA) dog has not previously been clinically characterised or described ...

Cataracts are the leading cause of vision loss in dogs. Once they impair sight, there is no other recourse than to have phacoemulsification cataract removal with intraocular lens placement to restore optimal sight. Even early cataracts cause inflammation (lens-induced uveitis) and oxidative stress...
