Progressive retinal atrophy (PRA) is a hereditary disease that affects dogs' eyes, leading to gradual vision loss and eventual blindness. This condition is also known as progressive rod-cone degeneration, degenerative retinal atrophy, and progressive retinal degeneration. PRA primarily affects the photoreceptor cells in the retina, leading to their gradual degeneration and dysfunction. Although there is no cure for PRA, early detection through comprehensive eye exams can help manage the condition and slow the progression of vision loss. Therefore, it is essential for pet owners to be aware of this disease and take preventative measures by regularly monitoring their pet's eye health.
