Border Terrier Hereditary Cataract

Hereditary cataract. Last year the Border Terrier was removed from the list due to the low number of affected dogs which had been found.

This might sound like a positive move but in reality so few dogs were actually screened that it probably did not give a true representation of the possible incidence of this condition within the breed.

Hereditary cataracts are known to be present in many breeds and although there is some difference in the appearance of the cataract and the means of inheritance between breeds they can be broadly divided into two categories; juvenile where the changes can be seen within the first few months of life and late onset where changes aren’t usually present until between 3 and 7 years of age. Juvenile cataracts will usually be present and of similar size in both eyes and will often lead to significant sight loss or total blindness by 2 to 3 years of age if left untreated. Late onset hereditary cataracts may be unilateral or bilateral, vary in shape and in the speed at which they progress often taking quite a few years before they significantly interfere with vision. By the time they become apparent affected animals may well already have been bred from.
