Cataracts in Senior Pets

There are many causes for vision loss in older dogs, the most probable being cataracts. Inside the eye is a structure called the lens. When light enters the eye, the lens focuses the light on the back of the retina. When a cataract forms, the lens becomes opaque and does not permit an image to form on the retina which will cause either partial or complete vision loss. The lens of the eye will appear to have a hazy or opaque growth and the eye will look cloudy.

Cataracts are common in older dogs but can occur at any age. Factors that can lead to the development of cataracts in dogs include diabetes mellitus, some type of trauma to the eye, hereditary or genetics, or inflammation and other eye disorders such as glaucoma. Due to inflammation cataracts may be painful, and if left untreated, can cause blindness.Dog Cataracts
