Details about the disease
In the Shar Pei, both POAG and PLL appear to be caused by the same mutation. Primary glaucoma is a painful and blinding disease associated with high pressure inside the eye. In POAG/PLL, glaucoma results from reduced drainage of fluid from the eye, causing a build-up of pressure which then leads to pain and blindness.
Most dogs become affected at approximately 4-6 years of age. The eyes become enlarged and the lens of the eye becomes wobbly and can even fall out of its normal position.
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.
