Llama Squinting: Eye Pain, Ulcer or Foreign Body?
- Squinting, a tightly closed eye, tearing, and light sensitivity are common signs of a painful eye problem, not a minor irritation.
- Important causes include corneal ulcer, hay or grass foreign body, eyelid injury, conjunctivitis, trauma, and less commonly deeper eye disease.
- Do not put human eye drops, steroid eye medications, or leftover ointments in the eye unless your vet has examined the cornea first.
- A same-day farm or clinic exam often includes an eye exam and fluorescein stain to look for an ulcer; deeper injuries may need sedation, eyelid eversion, or referral.
Common Causes of Llama Squinting
Llama squinting usually means the eye hurts. In camelids, pain can come from a corneal ulcer, a foreign body such as hay, seed heads, dust, or bedding, or trauma from fencing, herd mates, or rubbing. Merck notes that corneal foreign bodies and corneal ulcers are ophthalmic emergencies because rapid diagnosis and treatment help protect vision. Corneal ulcers are especially painful and may cause tearing, cloudiness, redness, and a llama that keeps the eye partly or fully closed.
Another possibility is conjunctivitis or pinkeye-like disease. In large animals, infectious keratoconjunctivitis causes blepharospasm, tearing, conjunctivitis, and corneal opacity. Even if the problem starts as irritation or infection, rubbing and delayed treatment can lead to an ulcer. Eyelid problems, abnormal hairs rubbing the cornea, and dry or exposed corneas can also keep the eye inflamed.
Less common but important causes include uveitis, deeper trauma, or a ruptured globe. If the eye looks blue-white, very cloudy, swollen, bleeding, or misshapen, that raises concern for a more serious injury. Because several different problems can look similar from the outside, your vet usually needs to stain the cornea and examine the eye closely before choosing treatment.
When to See the Vet vs. Monitor at Home
See your vet immediately if your llama is squinting hard, holding the eye shut, rubbing the face, showing marked tearing, or acting painful. Same-day care is also important if you see cloudiness, a blue or white spot on the cornea, blood, pus-like discharge, eyelid swelling, a visible foreign body, or any history of trauma. These signs fit with painful corneal disease or injury, and delays can make healing slower and vision loss more likely.
A short period of monitoring may be reasonable only if the eye opened again quickly after a brief dusty exposure, the llama is comfortable, vision seems normal, and there is no cloudiness, no discharge, and no ongoing squinting. Even then, recheck the eye often over the next few hours. If squinting returns, the eye waters, or the cornea looks dull instead of clear, call your vet.
Do not try to diagnose an ulcer at home. Steroid-containing eye medications can worsen some corneal ulcers, and human redness-relief drops are not a safe substitute for a veterinary eye exam. If you are unsure, it is safer to treat squinting as urgent.
What Your Vet Will Do
Your vet will start with a careful eye exam and look for obvious trauma, discharge, eyelid injury, or debris trapped under the lids. A fluorescein stain is commonly used to check for a corneal ulcer, and your vet may flush the eye with sterile solution to remove loose material. If the llama is painful or hard to examine safely, light sedation may be needed so the eyelids can be opened fully and the eye can be inspected without causing more stress or injury.
If your vet finds a superficial ulcer or foreign body, treatment often includes a topical antibiotic, pain control, and follow-up exams to make sure the cornea is healing. Merck describes superficial ulcers as commonly managed medically, while more complicated ulcers may need more frequent medication, correction of mechanical causes, and closer monitoring. Your vet may also check for deeper infection, melting ulcer changes, eyelid abnormalities, or signs that the inside of the eye is inflamed.
If the ulcer is deep, infected, melting, or the eye may be perforated, your vet may recommend referral for advanced ophthalmology care or surgery. Cornell’s camelid service includes ophthalmology support for llamas and alpacas, which can be important when vision is at risk or when the eye is not responding as expected.

Questions to Ask Your Vet About Llama Squinting
Bring these questions to your vet appointment to get the most out of your visit.
- Does this look like a corneal ulcer, a foreign body, conjunctivitis, or a deeper eye problem?
- Was a fluorescein stain done, and how deep or large is the corneal injury if one is present?
- Do you see hay, seed heads, abnormal hairs, or eyelid problems that could keep irritating the eye?
- Which medications are for infection control, which are for pain, and how often do they need to be given?
- Are any steroid-containing eye products unsafe for this specific eye problem?
- What changes would mean the eye is getting worse and needs recheck sooner?
- How soon should this eye be rechecked to confirm healing?
- At what point would referral or surgery be worth discussing for this llama?
Home Care & Comfort Measures
Home care should support, not replace, a veterinary exam. Keep your llama in a clean, low-dust area away from blowing bedding, seed heads, and bright sun if light seems painful. Reduce rubbing risks by removing sharp hay stems and checking fencing or feeders for anything that could poke the eye again. If your vet prescribed eye medication, give it exactly as directed and wash your hands before and after handling the eye area.
You can gently wipe discharge from the skin around the eye with clean gauze dampened with sterile saline or clean water, but do not press on the eyeball. Do not try to pull out a stuck foreign body, and do not use human eye drops unless your vet specifically says they are safe for this llama. ASPCA guidance for eye care in animals also warns against touching the eye surface while cleaning because the cornea can be scratched.
Call your vet sooner if the eye becomes more closed, more cloudy, more swollen, or starts producing thicker discharge. A llama that stops eating, isolates from the herd, or resists handling may be showing worsening pain. Even when the eye looks better, keep the scheduled recheck so your vet can confirm the cornea has truly healed.
