What Is It: A cataract is any opacity which develops in the crystalline lens of the eye or in its envelope. The opacity ranges from small marks that barely interfere with vision to deeply clouded lenses that cause blindness. High blood pressure, diabetes, and eye inflammation or trauma can cause cataracts and blindness at any age; otherwise, normal aging can also result in a gradual loss of vision. Cataracts are inherited. Tear production also diminishes with age, leading to other vision problems, such as dry eye (keratoconjunctivitis sicca).
Symptoms: Blue-gray tinted eye lens
Treatment: A veterinary ophthalmologist can surgically remove most cataracts with a success rate of 90 percent in dogs (somewhat less in cats). Intraocular lenses can now be implanted to help with vision focus and acuity. Oral and localized medication is compulsory after surgery to prevent infections. As cataracts are closely connected to diabetes, treating this disease will reduce the chances of your pet developing cataracts in the first place.
