Details about the disease
PRA (Progressive Retinal Atrophy) is a condition that causes the parts of the eye that are sensitive to light to break down. PRA produces a gradual loss of vision in both eyes, eventually leading to total blindness. A number of breeds are affected by PRA, and although the clinical effects are usually the same, each breeds version of PRA is often caused by a different genetic mutation. Sadly there is no cure for PRA.
Clinical signs
Vision loss and eventual blindness.
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.
