X-linked progressive retinal atrophy 3 · X-linked PRA type 3 · X-chromosomale progressive Retinaatrophie Typ 3 · Geschlechtsgebundene progressive Retinaatrophie 3 · Retinal atrophy, progressive, X-linked, type 3
This is an inherited eye disease where the light-sensitive cells of the retina, which is the back part of the eye, gradually break down. Because the genetic defect is carried on the X chromosome, male dogs are primarily affected by vision loss, while female dogs are typically unaffected carriers. Since the specific genetic mutation is currently unknown, there is no DNA test, and diagnosis relies on specialist clinical eye examinations.
Owners typically first notice signs of night blindness, such as hesitancy or bumping into objects in the dark, starting in early to middle adulthood. As the disease progresses, the vision loss extends to daylight hours, eventually leading to complete blindness.
There is no cure for this progressive condition, and management focuses on supportive care to help the dog adapt to vision loss. Lifetime costs for diagnostic eye examinations and supportive aids typically range from 400 to 1500 EUR.
