Cats can suffer from several eye conditions that can affect or impair their vision. A condition that can affect cats as well as people is known as cataracts. Cataracts result in a clouding of the lens or surrounding tissue, and may eventually result in blindness. Cataracts may be age-related, but may also be caused by several other factors such as damage from trauma or infection. Nutritional deficiency and abnormal development of the lens may also be underlying factors in the development of cataracts.

Appearance
-
The most notable symptom is a spot over the pupil. A slight color change within the eye may be noticed at first. The color change may be white, yellowish-white, bluish or gray. As the condition progresses, the eye may take on a milky appearance. It may appear as if there is a film over the eye.
Redness
-
Cataracts caused by infection will display signs of redness and inflammation. There may be slight swelling as well.
Pain
-
The condition can be painful, especially when infection is present. The cat may display symptoms of pain such as squinting or holding the eye partially closed.
Impaired vision
-
If the condition has progressed enough to hinder the eyesight, you may notice the cat bumping into furniture, hesitating to climb stairs, going outside or engaging in normal activities.
Discharge
-
A runny discharge may drain from the eye. Although drainage does not occur in all cases of cataracts, it may appear in some instances especially when cataracts are caused by an underlying infection. Discharge may be clear or cloudy.
Age
-
Cataracts may be age-related in felines just as they are in humans. An older cat is more likely to develop cataracts.
Treatment
-
Cataracts can cause permanent damage to the eye. Although cataracts cannot be prevented, early diagnosis is key to treating the underlying causes and preventing further damage and/or blindness. Professional treatment is necessary, and surgery may be an option.
