DNA test - PLL
Primary Lens Luxation
Details about the disease
In affected dogs, the zonular fibres which support the lens in the eye, breakdown or disintegrate, causing the lens to fall into the wrong position within the eye. If the lens falls into the anterior chamber of the eye, glaucoma and loss of vision can quickly result. PLL is a well-recognised, painful and blinding inherited eye condition that affects many breeds of dog.
Glaucoma (increased pressure within the eyeball) and loss of vision
How it is 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.
