Retinal atrophy - Rod-cone dysplasia 1(rcd1)
Also known as: Rod-cone dysplasia 1 · rcd1-PRA · Progressive Retinal Atrophy rcd1 · Stäbchen-Zapfen-Dysplasie 1 · PDE6B-PRA · …
Overview
What it is
This is an inherited eye disease affecting the retina, which is the light-sensitive layer at the back of the eye. In affected dogs, the specialized photoreceptor cells—specifically the rods, which detect dim light, and the cones, which detect color and bright light—do not develop properly and prematurely break down. This progressive degeneration ultimately leads to a complete loss of vision.
How it presents
Owners typically first notice night blindness or difficulty navigating in the dark when puppies are as young as six weeks old. As the disease progresses, daytime vision also deteriorates, usually resulting in complete blindness by one year of age.
Treatment
There is no cure or effective medical treatment to reverse or stop this condition. Lifetime costs of 300 to 1,500 EUR are primarily spent on supportive veterinary care, regular eye examinations, and adapting the home environment to help a blind dog navigate safely.
