Lens Disorders in Cats*

Lens Disorders in Cats

This article focuses on the differences in the presentation of lens disorders in cats. Pathology can be grossly separated into disorders characterised by opacification or by loss of stability, but typically the aetiopathogenesis of these disorders is quite different to that of dogs (see: Lens disorders in dogs – VetCPD Journal Vol 4, Issue 2, 2017). Primary, hereditary disorders of the lens are rare and instead both cataracts and lens luxation are typically secondary to other ocular disease. The management of traumatic lens rupture due to penetrating injury is also covered here, which although a common presentation for both dogs and cats, it is the cat claw which typically is most adept at inflicting the damage.
