This is an inherited eye disease where a genetic mutation in the CNGB1 gene causes the light-sensitive cells of the retina at the back of the eye to slowly degenerate. Over time, these photoreceptor cells, which are responsible for capturing light and sending visual signals to the brain, stop functioning and die off. This leads to a progressive and permanent loss of vision in both eyes.
Owners typically first notice night blindness or difficulty navigating in dim light during early to middle adulthood. As the disease advances, the dog's daytime vision also deteriorates, eventually leading to complete blindness.
There is no cure for this condition, and the resulting blindness is permanent but painless. Management focuses on supportive care and regular veterinary ophthalmologist exams, with lifetime costs typically ranging from 500 to 2000 EUR.
Estimated range of typical treatment cost. Actual cost depends on severity, clinic and region.
