There are several diseases and disorders that can cause a dog's eyes to become discolored or cloudy. Some of these are cause for immediate medical attention, while others are of less concern.
-
Disorder Detection
-
According to ThePetCenter.com, many internal canine problems can be detected through examination of the eyes. Organ failure or other diseases often manifest themselves through eye discoloration.
Yellow Eyes
-
A yellow tint to the normally white part of a dog's eye often suggests dysfunction of either the liver or red blood cells.
Cloudiness
-
Cloudiness in a dog's eye can signify several different things, and it may or may not cause reduced vision. According to PetPlace.com, some causes could be the accumulation of "white blood cells, protein, fatty lipids or blood." It could also be caused by cataract formation, which is the leading cause of blindness.
Redness
-
Redness in canine eyes can be a symptom of glaucoma, a condition that causes intraocular pressure to build in the eye. This often leads to loss of vision.
Home and Veterinary Treatment
-
According to ThePetCenter.com, there are home eye wash products on the market that can be beneficial to dogs. Human products like Visine, though, should never be used on dogs as they may temporarily decrease redness, but will not help in any other way. Redness of the eyes should always be checked on by a veterinarian.
