Conure Squinting or Keeping One Eye Closed: Causes & What to Do

Conures may squint or hold one eye shut when the eye is painful, irritated, or inflamed. Common causes include dust, seed hulls, dander, grooming products, cleaning fumes, or minor trauma from toys, cage bars, or another bird. Birds with conjunctivitis often show blinking, squinting, redness, swelling, or discharge. Merck notes that swelling, redness, discharge, excessive blinking, or holding the eye closed should prompt veterinary attention, because eye inflammation in birds may be limited to the eye or tied to a broader illness.

A scratch on the cornea can be especially painful and may make your conure keep the eye tightly closed. Corneal injury can happen after rubbing the face on a perch, bumping into an object during flight, or getting poked by a toy or cage accessory. Chemical irritation is another concern. Household cleaners, aerosols, smoke, and other fumes can irritate delicate avian eyes and airways.

Sometimes the eye is not the only problem. In birds, eye signs can occur with respiratory or sinus disease, including infections that cause nasal discharge, facial swelling, or lethargy. Deeper inflammation inside the eye, called uveitis, is less common but more serious and may be linked to systemic disease. Cataracts, masses, and eyelid abnormalities are also possible, though they are less common than irritation, trauma, or conjunctivitis.

Because birds are good at masking illness, even a "small" eye change deserves attention. A conure that keeps one eye closed for more than a brief moment after waking, bathing, or preening should be watched closely and usually examined by your vet the same day or within 24 hours.

See your vet immediately if your conure has eye swelling, redness, discharge, cloudiness, visible injury, bleeding, a bulging eye, sudden vision changes, or severe pain. Go the same day if your bird is fluffed, weak, sitting low, not eating, breathing harder, or keeping the eye closed most of the time. In birds, eye problems can progress quickly, and eye inflammation may be part of a respiratory or whole-body illness.

It is reasonable to monitor briefly at home only if the squinting happened once after a bath, a nap, or a short burst of dust exposure, and your conure is otherwise bright, active, eating normally, and opening the eye comfortably within a short time. Even then, if the behavior returns, lasts more than a few hours, or you notice any discharge or swelling, schedule an exam.

Do not try to diagnose the cause by looking alone. A painful corneal ulcer, conjunctivitis, foreign material under the eyelid, and deeper eye disease can look similar to a pet parent. Also avoid waiting several days to "see if it clears up" if one eye stays partly or fully closed. Birds often compensate until disease is advanced.

If you are unsure, call an avian or exotics clinic and describe exactly what you see: one eye versus both, any discharge color, whether the eye looks cloudy, and whether your conure is eating and perching normally. That helps your vet decide how urgently your bird should be seen.

Your vet will start with a careful history and physical exam. Expect questions about when the squinting started, whether there was trauma, any new cleaners or aerosols in the home, exposure to other birds, appetite changes, and whether there is nasal discharge or sneezing. In birds, eye signs can overlap with sinus and respiratory disease, so the exam usually goes beyond the eye itself.

The eye exam may include checking the eyelids, conjunctiva, cornea, pupil, and the tissues around the eye. Your vet may use fluorescein stain to look for a corneal scratch or ulcer, gently flush the eye if debris is suspected, and examine any discharge under magnification. Depending on findings, they may recommend cytology, culture, bloodwork, or imaging such as skull radiographs if sinus disease, trauma, or a deeper problem is suspected.

Treatment depends on the cause. Options may include prescription ophthalmic antibiotics, pain control, anti-inflammatory medication when appropriate, supportive care, and treatment for any underlying respiratory or systemic disease. If the eye is severely injured or the bird is unstable, hospitalization, oxygen support, fluids, or referral to an avian specialist may be needed.

Bird eyes are delicate, and medication choice matters. Some eye medications that are useful in one condition can be harmful in another, especially if the cornea is ulcerated. That is why your vet will usually want to stain the eye before choosing certain drops.

Home care should support your vet's plan, not replace it. Keep your conure in a warm, low-stress environment with easy access to food and water. Reduce dust, avoid aerosols and strong cleaners, and remove anything that may have poked or irritated the eye. If your bird shares space with other birds and infection is possible, ask your vet whether temporary separation is wise.

Do not use leftover pet medications or human eye drops unless your vet specifically approves them. Avoid ointments, redness-relief drops, steroid-containing products, and contact-lens solutions unless prescribed for this exact problem. These can interfere with diagnosis or worsen certain eye injuries.

If your vet advises gentle cleaning, use only sterile saline and only on discharge around the eye, not forcefully into the eye unless you were shown how. Never scrub. Watch appetite, droppings, activity, breathing, and whether the eye is opening more comfortably after treatment starts. Birds that stop eating can decline fast.

Call your vet sooner if the eye becomes more swollen, cloudy, or painful, if discharge increases, or if your conure becomes fluffed, sleepy, weak, or less interested in food. With eye problems in birds, early reassessment is often the safest choice.
