Rabbit Squinting: Why One or Both Eyes May Be Closed or Painful

Squinting in rabbits usually means the eye is painful or irritated. One of the most common causes is a corneal ulcer, which is a scratch or sore on the clear surface of the eye. Rabbits are especially prone to corneal injury because their eyes are large and prominent, and they blink less often than many other species. Hay stems, bedding, dust, rough grooming, or a scuffle with another rabbit can all injure the cornea.

Other common causes include conjunctivitis and dacryocystitis, which is inflammation or infection involving the tear duct. These problems may cause redness, tearing, white or yellow discharge, crusting, and repeated pawing at the face. In rabbits, tear duct disease is often tied to dental disease, especially overgrown or infected tooth roots that press on nearby structures.

Some rabbits squint because of deeper eye disease, such as uveitis, glaucoma, or trauma. These conditions can cause severe pain, cloudiness, light sensitivity, or a bulging eye. Facial nerve problems can also reduce blinking and tear production, which leaves the eye dry and vulnerable to injury.

If only one eye is affected, a local problem like a scratch, foreign material, blocked tear duct, or tooth root issue is more likely. If both eyes are involved, your vet may also think about environmental irritants, infection, or a broader health problem.

For most rabbits, squinting is a same-day vet problem. Rabbits hide pain well, so a half-closed eye can be the visible part of a more serious issue. If your rabbit is holding the eye shut, rubbing at it, has discharge, redness, swelling, cloudiness, a blue or white spot on the eye, or seems less interested in food, call your vet promptly.

Seek urgent or emergency care right away if there was trauma, the eye looks suddenly enlarged or bulging, the surface looks cloudy or damaged, there is blood, or your rabbit is also lethargic, grinding teeth, or not eating. Eye pain can quickly lead to stress, reduced appetite, and gastrointestinal slowdown in rabbits.

Brief monitoring at home may be reasonable only if your rabbit had a very short episode of mild tearing after obvious dust or hay exposure, is otherwise acting normal, and the eye returns to normal quickly. Even then, if squinting lasts more than a few hours, comes back, or you see any discharge or redness, your rabbit should be examined.

Do not wait several days to see if it clears on its own. Eye disease in rabbits can worsen fast, and problems that look superficial can turn out to involve the cornea, tear duct, or tooth roots.

Your vet will start with a full history and a careful eye exam. They will look for discharge, eyelid swelling, corneal damage, reduced blinking, facial asymmetry, and signs of pain. In many cases, your vet will use fluorescein stain to check for a corneal ulcer and may measure eye pressure with tonometry if glaucoma or uveitis is a concern.

Because rabbit eye problems are often linked to the tear duct and teeth, your vet may also examine the mouth and skull shape, and may recommend skull radiographs or advanced imaging if dental disease, tooth root elongation, or an abscess is suspected. If dacryocystitis is present, your vet may flush the tear duct and collect material for testing in some cases.

Treatment depends on the cause. Options may include rabbit-safe pain control, antibiotic eye medication, lubrication, tear duct flushing, treatment for dental disease, or surgery for severe ulcers, abscesses, or a nonfunctional painful eye. Your vet will choose medications carefully because some antibiotics and some eye products are not appropriate for rabbits.

If your rabbit is painful or eating less, your vet may also address hydration, nutrition support, and gut motility concerns. With rabbits, treating the eye and protecting appetite often need to happen at the same time.

Home care should support, not replace, veterinary treatment. Keep your rabbit in a clean, low-dust, low-stress area with easy access to hay, water, and favorite greens approved by your vet. If discharge is collecting on the fur, you can gently wipe the area with sterile saline or a soft damp cotton pad, but do not press on the eye.

Give all medications exactly as prescribed. Do not use leftover pet medications, human eye drops, or steroid-containing eye products unless your vet specifically says they are appropriate. Some eye medications can make ulcers worse or delay healing.

Watch appetite closely. A painful rabbit may eat less, and that can quickly become a bigger problem. If your rabbit is reluctant to eat, producing fewer droppings, hiding, or grinding teeth, contact your vet right away.

Try to prevent repeat irritation by checking hay racks, bedding, and the environment for dust or sharp stems. If your rabbit has recurring squinting or discharge, ask your vet whether tear duct disease or dental disease could be driving the problem, because repeated flare-ups often need more than surface treatment.
