Retinal atrophy - Rod-cone dysplasia 1a(rcd1a)
Also known as: Rod-cone dysplasia 1a · rcd1a-PRA · Progressive Retinal Atrophy rcd1a · Stäbchen-Zapfen-Dysplasie 1a · PDE6B-associated PRA
Overview
What it is
This is an inherited eye disease affecting the retina, which is the light-sensitive tissue at the back of the eye. It is caused by a genetic defect that prevents the eye's light receptors, called rods and cones, from developing properly. As these essential cells prematurely break down and die, the dog progressively loses its sight.
How it presents
Owners typically first notice night blindness in puppies around six weeks of age, characterized by bumping into objects or hesitating in the dark. The disease progresses rapidly, usually resulting in complete blindness by one year of age.
Treatment
There is no cure for this condition, and management focuses on helping the dog adapt to its vision loss. Veterinary costs for the initial diagnosis and supportive care typically range from 150 to 800 EUR.
