Causes
Ageing, genetic predisposition (breeds such as the Poodle, Cocker Spaniel and Husky), diabetes (which causes rapidly developing cataracts) and trauma. Not to be confused with senile sclerosis (normal with age and without serious loss of vision).
Diagnosis
Ophthalmic examination. The vet distinguishes a cataract from senile sclerosis and assesses the rest of the eye.
Treatment
The only effective treatment is SURGERY (replacing the lens), with very good results if the eye is otherwise healthy. Not all cases are operable.
Prevention
Hereditary cataracts cannot be prevented. Controlling diabetes to avoid diabetic cataracts. Eye check-ups in senior pets.
