Cataracts in Birds

What is a cataract?

A normal eye lens in any animal is clear and colorless. A cataract is an increase in the density or opacity of the lens. It is often seen as whiteness within the pupil. The pupil is the space the lens occupies in the center of the eye and is surrounded by the iris, the colored portion of the eye.

What causes cataracts?

Common causes of cataracts include nutritional problems, traumatic events, metabolic diseases (e.g., diabetes), inflammatory problems, and infections.

Cataracts are often seen in canaries and are thought to be inherited. Cataracts occur less commonly in most species of parrots. Cataracts in parrots are usually age-related and often involve both eyes.

How are cataracts in birds treated?

Depending on the size of your bird, it may be possible for a cataract to be surgically removed, although the procedure can be difficult. Discuss this treatment option with your avian veterinarian or a veterinary ophthalmologist.

Will a cataract affect my bird’s vision?

Cataracts will decrease your bird’s visual acuity and may eventually lead to blindness. Many birds with cataracts can still see, although with blurred vision. Even with cataracts, your bird can still live a happy life.

What should I do if my bird becomes blind?

Many owners do not realize their bird is blind until a veterinarian points it out. In general, a healthy pet bird that is blind does well, as long as the owner does not change the bird’s routine or cage setup. It is essential not to rearrange perches, toys, or food dishes in a blind bird’s cage, since they know exactly where everything is and may have difficulty finding items in new locations.

Birds with cataracts may startle easily if you approach too fast, so you should verbally announce when you are approaching. Consult your veterinarian if you are concerned your bird may have cataracts or if you have questions about the condition.
