This is seen in older dogs but has cropped up occasionally on dogs under 5 years of age. It is a growth that can range from a small speck to completly covering the eye. Depending on the size, vision can be greatly impaired. A surgical proceedure can remove the cataract.
This is the most common eye problem in the breed. Also called "loose lids", simply put the eyelids hang or are looser than normal. While not life threatening, dust and other foreign items can enter the eye causing mild to severe infections. Mild cases can be treated with eye ointment or creams from a veterinarian. Severe cases require ean eye "tuck" where the lids are tightened. This condition can be both hereditary and enviromental.
PROGRESSIVE RETINAL ATROPHY(PRA)
This is a touchy subject in Field circles. This disease appears mainly in older dogs although there have been two cases in Canada where it was detected in dogs under the age of 3 years. Symptoms start as nightblindness and gradually progress into total blindness. Unlike most other eye disorders there is NO cure for PRA.
There have been "whispers" of cases in the USA but NO ONE has admitted to it. The three cases in Canada were all from the SAME dam that was imported from the UK. And I owned one of these dogs.
Many USA breeders will say that this was a Canadain bred problem or only found in Canada. Make sure ANY puppy you buy comes from parents AND grandparents that were cleared by CERF* from age 2 years and up. Because this is generally a late developing condition, a 4 year old bitch that was cleared at age 2 and not checked again is no beter than a bitch that has never been checked.
Simply put, "folds" are small blind spots in the eye whereas "dysplasia" are larger and more severe. With folds a dog can live a normal life and never notice the slight distortoin in his vision. Dysplasia can lead to retinal detachment causing blindness.
This can be detected in puppies as early as 8 weeks of age. CERF* strongly suggests that ALL puppies be checked at 6 months also.
It should be noted that adults that have retinal folds CAN produce blind puppies so ANY dog with these problems should never be bred.
