Adult parrot has one swollen, teary eye, with no obvious drop in appetite
Expert Answer
Hello. Because the photo you uploaded is too blurry, it is impossible to determine the specific situation of the parrot’s eye inflammation. But based on your description, the cockatiel’s eye inflammation is likely caused by a bacterial or viral infection. You can try cleaning its eyes with a pet eye-care solution once in the morning and once in the evening every day. After cleaning, apply a little anti-inflammatory eye drops, then put on a suitable amount of chlortetracycline or erythromycin eye ointment to reduce inflammation.
If you later notice other symptoms in the cockatiel — such as increased nasal discharge or a loss of appetite — it is recommended to take it to a veterinary clinic promptly to determine whether it is a chlamydia infection or another viral infection.
