Swelling and inflammation of the eyelids, called conjunctivitis, can be caused in birds by infection with bacteria, viruses, or other organisms. It might be confined to the eye, or it can be part of a more extensive respiratory infection. If not treated, conjunctivitis in birds can lead to cataracts in the affected eye.
Inflammation of the inner structures of the eye is called uveitis. Uveitis often indicates more widespread disease outside of the eye, in the rest of the body.
If your pet bird shows any swelling, redness, discharge, excessive blinking, or prolonged closure of one or both eyes, which are serious symptoms, it should be examined by a veterinarian as soon as possible. Most eye infections of birds respond well to eye drops or ointments.
