This is an inherited eye disease that causes the gradual breakdown of the retina, which is the light-sensitive tissue at the back of the eye. A genetic defect in the IMPG2 gene impairs the photoreceptor cells, which are the specialized cells responsible for detecting light and enabling vision. In the Lhasa Apso breed, this specific condition is commonly referred to as PRA4.
Affected dogs typically begin showing signs of night blindness, such as bumping into objects or hesitating in dim light, during early to mid-adulthood. As the disease progresses, daytime vision also declines, eventually resulting in complete blindness.
There is no cure for this condition, and the resulting blindness is permanent. Managing the disease involves lifelong supportive care and environmental adjustments to keep the dog safe, with expected veterinary and management costs ranging from 500 to 2000 EUR.
