Details about the disease
This disease causes day blindness due to retinal cone degeneration. Cones in the retina are cells that respond mainly to bright daylight. Unlike PRA (progressive retinal atrophy), cone degeneration does not affect night vision.
Clinical signs
Signs of vision problems are noticeable between 8 and 12 weeks of age. Exposure to bright light will be irritating or painful, but their vision in dim light remains normal.
How is it inherited?
The disease is described as an autosomal-recessive condition. This means that a dog must inherit two copies of an abnormal gene (one from its mother and one from its father) before its health is affected. A dog that inherits only one copy of the abnormal gene (from its mother or its father) will have no signs of the disease, but will be a carrier and may pass the gene on to any offspring.
