According to the American Animal Hospital Association (AAHA), cataracts are a common disorder in all dogs, regardless of breed. While cataracts can be controlled and slowed in some cases, there is no cure.

Definition
-
A cataract develops when the lens fibers begin to breakdown in the eye. This causes the normally transparent lens to become clouded, which in turn reduces vision.
Categories
-
Cataracts are categorized by their level of severity as immature, mature and hypermature. An immature cataract is one that is newly formed and may cause some blurred vision. One that is mature covers more of the lens surface and causes a cloudiness of the lens that interferes significantly with vision. A hypermature cataract is advanced and may also be smaller in size than during the mature stage due to a loss of lens moisture and proteins.
Causes
-
Cataracts may be inherited, though the Pug does not fall into the category of breeds that are most often associated with this type of cataract. Cataracts may also be caused by injury to the eye, diabetes, drug reactions and infection.
Cure
-
Nutritional supplements may aid in preventing and diminishing the development of cataracts; however, there is currently no way to reverse the damage caused by cataracts.
Treatment
-
The only treatment for cataracts is to have them surgically removed. This is a common procedure and usually very successful. Cataracts that go untreated may progress into more severe conditions of the eye and eventually cause blindness.
Important Note
-
Before you decide on surgery for your Pug, discuss it in detail with your veterinarian. Many factors should be considered depending on your specific circumstances.
