Red, weepy eyes in a rabbit can signal conjunctivitis — but rabbit eye infections are often more complicated than they first appear. In many cases, a rabbit's eye problem stems not from the eye itself, but from an underlying dental condition, a blocked tear duct, or an infectious disease. In 2026, conjunctivitis remains one of the more common presentations in rabbits seen by exotic vets, and untreated cases can escalate to serious eye damage within days.
What Is Conjunctivitis in Rabbits?
Conjunctivitis is inflammation of the conjunctiva — the thin, transparent tissue that lines the inner eyelids and covers the white of the eye. When inflamed, it causes redness, swelling, and discharge. In rabbits, conjunctivitis can be unilateral (one eye) or bilateral (both eyes), and this distinction matters for diagnosis.
Signs of Rabbit Eye Infection
According to the PDSA, signs of conjunctivitis and eye infection in rabbits include:
- Red or pink whites of the eye — the most obvious sign
- Discharge from the corner of the eye — ranging from clear and watery to thick white, yellow, or green
- Squinting or partially closed eye — indicates pain or discomfort
- Crusting around the eyelid — discharge that dries and mats the fur
- Wet fur on the face or inside of the front legs — from rubbing the eye
- Fur loss below the eye — from constant moisture and friction
What Causes Rabbit Conjunctivitis?
Dental Disease (Very Common — and Often Overlooked)
This is one of the most important causes unique to rabbits. Rabbit tooth roots grow very close to the tear ducts and nasal passages. Overgrown or abscessed teeth — particularly the upper premolars and molars — can physically compress the nasolacrimal duct (the channel that drains tears from the eye into the nasal passage), causing tears to overflow and the eye to become infected.
If a rabbit has dental problems AND an eye discharge, the dental condition is likely driving the eye problem. Treating the eye alone without addressing the dental issue will not resolve it.
Bacterial Infection
Pasteurella multocida — the same bacteria that causes snuffles — is a common cause of conjunctivitis in rabbits. The infection often spreads from the upper respiratory tract to the nasolacrimal duct and conjunctiva. Both eyes are commonly affected.
Foreign Body
Hay, dust, or bedding particles lodged under the eyelid cause acute-onset inflammation and discharge, often unilateral.
Myxomatosis
In countries where myxomatosis is present (common in Europe, rare in the US), this viral disease causes severe bilateral conjunctivitis and swelling. Vaccination is available and strongly recommended in endemic areas.
Trauma or Eyelash Abnormality
A scratch to the eye, or abnormal eyelashes (entropion) that rub against the cornea, can cause secondary conjunctivitis.
When to See an Exotic Vet — and How Quickly
The PDSA and House Rabbit Society recommend seeing a vet within 24 hours of noticing any eye signs in a rabbit, because:
- Eye conditions in rabbits can progress to corneal ulceration very quickly
- Dental-related causes require veterinary diagnosis and treatment (not just eye drops)
- Pasteurella infections often require systemic antibiotics
Seek emergency exotic vet care if:
- The eye is bulging, sunken, or grossly abnormal in appearance
- Your rabbit is in obvious pain and pawing at the eye constantly
- There is blood or brown/red discharge suggesting injury
- Your rabbit has stopped eating (potentially from pain)
Treatment
Treatment depends entirely on the underlying cause:
- Antibiotic eye drops — for bacterial conjunctivitis; vet-prescribed only
- Nasolacrimal duct flushing — to clear a blocked tear duct
- Dental treatment — if overgrown teeth are the root cause
- Foreign body removal — by your vet under magnification
- Artificial tears — to keep the eye moist while healing
Never use over-the-counter human eye drops on rabbits without veterinary guidance.

Frequently Asked Questions
Q: Can I use human eye drops on my rabbit? A: No — many human eye preparations contain ingredients that are not safe for rabbits. Only use products specifically prescribed or recommended by a rabbit-savvy vet.
Q: My rabbit has discharge from one eye only — what does that mean? A: Unilateral (one-sided) discharge often points to a blocked nasolacrimal duct, dental disease affecting one side, or a local foreign body. Bilateral (both eyes) discharge more often suggests systemic infection like Pasteurella.
Q: How can I clean my rabbit's eye at home while waiting for the vet? A: Gently wipe discharge away using a soft cloth or cotton ball dampened with sterile saline solution, wiping from the inner corner outward. Do not rub or press on the eyeball. This provides temporary comfort but does not treat the underlying cause.
Q: Can rabbit eye infections spread to other rabbits? A: Bacterial infections like Pasteurella can spread between rabbits in close contact. If you have a multi-rabbit household, isolate the affected rabbit until evaluated by a vet.
