Xerophthalmia in Conures: Dry, Damaged Eyes From Vitamin A Deficiency
- Xerophthalmia is severe eye dryness and damage that can happen when a conure has long-term vitamin A deficiency.
- Common early clues include swollen eyelids, eye discharge, crusting around the nostrils, squinting, and dull or thickened tissues around the eyes and mouth.
- Seed-heavy diets are a major risk factor in parrots, including conures. Many affected birds also have respiratory or mouth changes at the same time.
- Prompt veterinary care matters because untreated eye disease can lead to infection, corneal injury, vision loss, and whole-body illness.
- Typical 2025-2026 US cost range for exam, eye evaluation, and diet-based treatment planning is about $120-$450, with higher totals if cultures, imaging, hospitalization, or intensive care are needed.
What Is Xerophthalmia in Conures?
Xerophthalmia means abnormal dryness and damage of the eye surface. In conures, it is most often linked to vitamin A deficiency, also called hypovitaminosis A. Vitamin A helps maintain healthy epithelial tissues, including the delicate lining of the eyes, sinuses, mouth, and respiratory tract. When levels stay low for too long, those tissues become thickened, dry, and more vulnerable to debris and infection.
In parrots and other psittacines, vitamin A deficiency is classically associated with seed-heavy diets. Over time, the eye may look irritated, swollen, crusted, or cloudy. Some birds also develop white plaques or thick secretions around the eyes, nostrils, or mouth. Because the same deficiency affects more than the eyes, a conure with xerophthalmia may also have sneezing, noisy breathing, poor feather quality, or reduced appetite.
This is not a condition to diagnose at home. Several infections and injuries can look similar, and birds often hide illness until they are quite sick. Your vet can sort out whether the eye changes are mainly nutritional, infectious, traumatic, or a combination of problems.
Symptoms of Xerophthalmia in Conures
- Mild to moderate eye discharge, especially thick, white, tan, or crusty material
- Swollen eyelids or puffiness around one or both eyes
- Squinting, blinking more than usual, or keeping the eye partly closed
- Dry, dull, or cloudy-looking eye surface
- Redness or irritation of the tissues around the eye
- Rubbing the face on perches or scratching at the eye
- Crusting around the nostrils or nasal discharge
- White plaques or thickened tissue in the mouth or around the choana
- Sneezing, wheezing, tail bobbing, or other breathing changes
- Reduced appetite, weight loss, lethargy, or fluffed posture in more advanced cases
See your vet immediately if your conure has a closed eye, obvious pain, trouble breathing, marked swelling, thick pus-like discharge, or is not eating. Birds can decline quickly, and eye disease may be only one part of a larger vitamin A deficiency or respiratory problem.
Milder signs still deserve an appointment soon. A watery eye can progress to crusting, infection, corneal damage, and vision loss if the underlying cause is not addressed. If your conure is on a mostly seed diet, mention that to your vet right away because it can be an important clue.
What Causes Xerophthalmia in Conures?
The most common underlying cause is long-term vitamin A deficiency, especially in conures eating mostly seeds with few formulated pellets and limited vitamin A-rich produce. Psittacine birds naturally rely on dietary carotenoids and other vitamin A precursors from plant foods. When the diet is narrow, the tissues lining the eyes and upper airway can change from smooth, moist surfaces to dry, thickened tissue that traps debris and bacteria.
In many birds, xerophthalmia is not an isolated eye problem. The same deficiency can affect the sinuses, mouth, choana, and respiratory tract. That is why some conures show eye discharge along with nasal crusting, sneezing, bad breath, or white plaques in the mouth. Secondary bacterial infection is common once the normal tissue barrier is damaged.
Other conditions can mimic or worsen xerophthalmia, including conjunctivitis from infection, trauma, foreign material, chemical irritation, and less commonly systemic disease. Your vet may also consider chlamydial infection, sinus disease, or corneal injury depending on the exam findings. That is one reason home vitamin drops alone are not a safe substitute for a proper workup.
How Is Xerophthalmia in Conures Diagnosed?
Diagnosis starts with a detailed history and physical exam. Your vet will ask what your conure actually eats day to day, not just what is offered. A seed-selective diet is a major clue. During the exam, your vet may look closely at the eyes, nostrils, mouth, and choanal papillae for thickened tissue, plaques, discharge, swelling, or signs of secondary infection.
Eye testing may include a fluorescein stain to check for corneal injury, gentle flushing, and sampling of discharge for cytology or culture if infection is suspected. Because vitamin A deficiency often affects more than one body system, your vet may also recommend bloodwork, imaging, or additional infectious disease testing in birds with breathing changes, weight loss, or severe illness.
There is no single at-home sign that confirms xerophthalmia. In practice, diagnosis is often based on the combination of diet history, exam findings, and response to a carefully supervised treatment plan. Your vet will also rule out look-alike problems such as trauma, primary conjunctivitis, sinus infection, or other nutritional disease.
Treatment Options for Xerophthalmia in Conures
Spectrum of Care means you have options. Here are treatment tiers at different price points.

Recommended Standard Treatment
- Comprehensive avian exam
- Detailed ophthalmic evaluation, often including fluorescein stain
- Cytology and/or culture of eye or choanal discharge when indicated
- Targeted medications chosen by your vet for secondary infection or inflammation when appropriate
- Supervised vitamin A repletion strategy through diet and, in selected cases, veterinary supplementation
- Recheck visit to confirm the eye surface and upper airway tissues are improving

Questions to Ask Your Vet About Xerophthalmia in Conures
Bring these questions to your vet appointment to get the most out of your visit.
- Does my conure’s eye problem look most consistent with vitamin A deficiency, infection, trauma, or a mix of causes?
- What parts of my bird’s current diet are putting them at risk, and what exact diet transition do you recommend?
- Do you see mouth, choanal, or sinus changes that suggest this problem is affecting more than the eyes?
- Does my conure need an eye stain, culture, bloodwork, or imaging today, or can we start with a more conservative plan?
- Which eye medications are appropriate for this case, and are there any products I should avoid using at home?
- How quickly should I expect improvement, and what signs mean the treatment plan is not working?
- What is the safest way to add vitamin A-rich foods without causing stress or selective eating?
- When should we schedule a recheck to make sure the eyes and upper airway tissues are healing?
How to Prevent Xerophthalmia in Conures
Prevention centers on balanced nutrition. For most conures, that means avoiding a seed-only or seed-heavy diet and working with your vet to build a feeding plan around a quality formulated pellet plus appropriate vegetables and some fruit. Foods rich in vitamin A precursors often include dark leafy greens, carrots, sweet potato, winter squash, and red or orange peppers. Gradual transitions are usually more successful than sudden diet changes.
Do not start high-dose vitamin supplements on your own. Birds can also be harmed by oversupplementation, especially with fat-soluble vitamins. Your vet can help you decide whether your conure needs diet correction alone or a more structured supplementation plan.
Routine wellness visits matter too. Conures should have regular avian exams so subtle diet-related changes can be caught before they become severe eye or respiratory disease. At home, watch for early clues like eye discharge, nasal crusting, reduced appetite, weight loss, or changes in droppings and behavior, and bring those concerns to your vet promptly.
