African Grey Parrot Swollen Eye or Eyelid: Sinus Disease, Injury or Infection?

A swollen eye or eyelid in an African Grey often starts with conjunctivitis, which means inflammation of the tissues around the eye. In birds, this can happen with bacterial, viral, fungal, or parasitic disease, but it can also follow irritation or trauma. Merck notes that swelling, redness, discharge, excessive blinking, and holding the eye closed all deserve prompt veterinary attention. PetMD also lists trauma, fume exposure, and vitamin A deficiency among common triggers in pet birds.

African Greys can also develop sinus or upper respiratory disease that shows up around the eyes. Birds have infraorbital sinuses close to the eye, so sinus inflammation may cause puffiness below or around the eyelids, nasal discharge, sneezing, or a change in breathing sounds. In parrots, infections such as chlamydiosis can sometimes involve the eyes and respiratory tract together, which is one reason your vet may ask about droppings, appetite, and any new bird exposure.

Injury is another important cause. A bird may scratch the eye, fly into a window or toy, get dust or bedding in the eye, or react to smoke, aerosols, cleaners, or overheated nonstick cookware fumes. VCA warns that birds are especially sensitive to airborne irritants and that oil-based products should not be used around them. Even mild-looking swelling can hide a corneal scratch or deeper damage.

Less commonly, swelling may be linked to nutritional problems, especially low vitamin A intake in birds eating mostly seed diets, or to masses, abscesses, or more serious infectious disease. Because the same outward sign can come from very different problems, your vet usually needs to examine the eye directly before treatment is chosen.

A mild, brief squint after a dusty bath or a tiny bit of irritation may improve quickly once the environment is cleaned up, but most swollen eyes in parrots should be checked by your vet within 24 hours. Birds can worsen fast, and eye problems may reflect sinus disease, infection, or injury rather than a surface irritation alone.

See your vet immediately if the eye is closed, cloudy, bleeding, or has thick discharge; if the swelling spreads into the face; if your African Grey is rubbing the eye constantly; or if there are whole-body signs like fluffed feathers, lethargy, poor appetite, weight loss, or breathing changes. Open-mouth breathing is especially urgent in birds. AVMA notes that birds are very sensitive to smoke and airborne irritants, and breathing difficulty with eye irritation should be treated as an emergency.

You can reasonably monitor only if the swelling is very mild, your bird is acting completely normal, eating well, breathing normally, and the eye looks clear with no discharge or trauma history. Even then, monitoring should be short. If the swelling lasts more than several hours, returns, or worsens by the same day or next morning, contact your vet.

Skip home treatment that could blur the picture. Do not apply human redness-relief drops, steroid creams, antibiotic ointments, or herbal products unless your vet has examined the eye and told you exactly what to use.

Your vet will start with a full history and physical exam, not just the eye. Expect questions about diet, cage hygiene, new birds, smoke or aerosol exposure, recent trauma, and whether you have noticed sneezing, nasal discharge, voice change, reduced appetite, or changes in droppings. In birds, eye swelling and sinus disease often overlap, so the exam may include the nares, mouth, choana, and breathing pattern.

For the eye itself, your vet may look for discharge, conjunctival redness, corneal injury, foreign material, eyelid damage, and swelling around the infraorbital sinus. Depending on what they find, they may recommend fluorescein stain to check for a corneal ulcer, cytology or culture of discharge, bloodwork, chlamydial testing, or imaging such as skull radiographs. In more complex cases, sedation may be needed for a safer and more complete exam.

Treatment depends on the cause. Options may include saline flushing, prescription ophthalmic medication, systemic antibiotics or antifungals, pain control, nutritional correction, or treatment directed at sinus disease. If there is an abscess, foreign body, or severe sinus blockage, your vet may recommend more advanced procedures or referral to an avian veterinarian.

Because some infectious causes in parrots can have public health implications, your vet may also discuss hygiene, isolation from other birds, and careful cleaning of the environment while test results are pending.

Home care should support your vet’s plan, not replace it. Keep your African Grey in a warm, clean, low-stress environment away from smoke, aerosols, scented sprays, candles, cooking fumes, and dust. Replace dirty cage paper daily, clean perches and food bowls well, and reduce anything that could poke or rub the face, such as frayed toys or sharp cage hardware.

If your vet recommends it, you may use sterile saline flush or prescribed eye medication exactly as directed. PetMD notes that saline flushes can be used in birds when recommended by a veterinarian. Use only products your vet approves. Avoid human eye drops that “get the red out,” oil-based ointments, essential oils, or leftover medications from another pet.

Watch closely for appetite, droppings, activity, and breathing. A bird with an eye problem that also becomes fluffed, sleepy, quieter than normal, or less interested in food needs a faster recheck. Weighing your bird daily on a gram scale can help catch early decline, especially if the swelling is part of a broader illness.

Offer easy access to familiar food and water, and minimize handling if your bird is stressed. If medication is difficult to give, tell your vet early. There may be other options, including a different formulation, a demonstration visit, or a treatment plan that better fits your bird and your budget.
