PLL - Primary Lens Luxation

Primary Lens Luxation (PLL) is an inherited condition that affects many breeds of dog. It is characterized my movement of the lens away from its normal location in the eye. This may result in blindness in affected adult dogs. A mutation has been identified by researchers at the Animal Health Trust which causes PLL. It is inherited as a recessive trait.



Affected

2 copies of the mutation and will likely develop PLL

Carrier

1 copy of mutation. Most carriers do not develop PLL but a small percentage will, and so these dogs should be periodically checked by an opthamologist.

Clear

No copies of the mutation
