Cone-Rod Dystrophy (Progressive Retinal Atrophy)(crd-PRA)
Also known as: Cone-Rod Dystrophy · Zapfen-Stäbchen-Dystrophie · Progressive Retinal Atrophy cone-rod dystrophy
Overview
What it is
Cone-Rod Dystrophy (crd-PRA) is an inherited eye disease that causes the progressive degeneration of the retina, the light-sensitive tissue at the back of the eye. It specifically damages the photoreceptor cells, starting with the cones, which detect bright light and detail, and eventually spreading to the rods, which are responsible for night vision.
How it presents
Symptoms usually appear during puppyhood or adolescence, with owners first noticing their dog squinting, showing sensitivity to bright light, or bumping into things in the daytime. Over time, this vision loss progresses to complete blindness.
Treatment
This condition is currently incurable, but it is painless and dogs can adapt well to gradual vision loss. Lifetime management, including regular veterinary ophthalmology check-ups and home safety adjustments, typically costs between 500 and 2000 EUR.
