Eye Infections in Rabbits: Conjunctivitis & Treatment

Quick Answer
  • Rabbit conjunctivitis means inflammation of the tissues around the eye. It can be caused by irritation, bacteria, viruses, blocked tear ducts, or dental disease.
  • Common signs include red or swollen eyelids, watery or thick discharge, squinting, pawing at the face, and fur loss or matting under the eye.
  • Eye discharge in rabbits is not always a simple infection. Dental root problems and tear duct disease are common underlying causes, so a full exam matters.
  • See your vet promptly if your rabbit keeps an eye closed, has thick white or yellow discharge, seems painful, stops eating, or has swelling around the eye.
  • Typical 2025-2026 U.S. veterinary cost range is about $90-$450 for exam and medical treatment, with dental imaging, tear duct flushing, sedation, or surgery increasing total costs.
Estimated cost: $90–$450

What Is Eye Infections in Rabbits?

Eye infections in rabbits usually refer to conjunctivitis, which is inflammation of the pink tissues lining the eyelids and surrounding the eye. Pet parents may notice this as a "weepy eye," pink eye, or sticky discharge. In some rabbits, the problem stays limited to the surface of the eye. In others, it is tied to a blocked tear duct, corneal injury, respiratory infection, or dental disease.

Rabbits are a little different from dogs and cats. Their tear ducts run close to the tooth roots, so eye discharge can sometimes be the first sign of a deeper dental problem rather than a stand-alone eye infection. That is why recurring or one-sided discharge deserves a careful exam.

Some cases are mild and respond well to cleaning, medication, and follow-up. Others need more investigation to find the true cause. Early care matters because rabbits can develop pain, corneal ulcers, or chronic tear duct problems if irritation and infection continue.

Symptoms of Eye Infections in Rabbits

  • Watery eye or tears running down the face
  • White, yellow, or green eye discharge
  • Red or inflamed conjunctiva
  • Swollen eyelids or puffy tissue around the eye
  • Squinting, blinking more than usual, or holding the eye partly closed
  • Pawing at the eye or rubbing the face with the front feet
  • Crusts, matted fur, or hair loss below the eye
  • Cloudiness of the eye or a visible surface defect, which can suggest a corneal ulcer
  • Bulging eye, facial swelling, or nasal discharge, which can point to dental root disease or deeper infection
  • Reduced appetite or quieter behavior, which may mean pain

Mild tearing can happen with dust or hay irritation, but persistent discharge is not normal in rabbits. Thick discharge, obvious redness, swelling, or repeated squinting should be checked by your vet. If your rabbit stops eating, keeps the eye closed, has a cloudy eye, or develops swelling around the eye or cheek, treat it as more urgent. Rabbits can hide pain well, and eye disease can worsen quickly.

What Causes Eye Infections in Rabbits?

Rabbit conjunctivitis has several possible causes. Irritants are common and include dusty bedding, poor ventilation, hay pokes, and debris trapped around the eye. Bacterial infection can also occur, sometimes along with respiratory disease. Merck notes that conjunctivitis in rabbits may be associated with irritants, eyelid disorders, and dental disease, and that dacryocystitis, or tear duct inflammation, often occurs at the same time.

A very important rabbit-specific cause is dental disease. Overgrown or infected tooth roots can narrow or block the nasolacrimal duct, causing chronic tearing, discharge, and repeated infection. This is one reason one-sided eye discharge should not be dismissed as a minor problem.

Other causes include corneal ulcers or trauma, eyelid abnormalities, viral disease, and less commonly systemic infectious disease. In outdoor rabbits or rabbits exposed to insects or infected rabbits, serious infectious diseases can also involve the eyes. Your vet may need to sort out whether the eye itself is infected, the tear duct is blocked, or the eye signs are secondary to another condition.

How Is Eye Infections in Rabbits Diagnosed?

Diagnosis starts with a hands-on exam and a close look at the eye, eyelids, and surrounding fur. Your vet will ask when the discharge started, whether one or both eyes are affected, and whether your rabbit is eating normally. They will also look for signs of pain, facial asymmetry, nasal discharge, and dental disease.

Depending on the findings, your vet may recommend fluorescein staining to check for a corneal ulcer, a tear duct flush to look for blockage, and a sample of discharge for cytology or culture if infection is suspected. A mouth exam is important, but rabbits can have significant tooth root disease even when the front teeth look normal.

If the problem keeps coming back, is one-sided, or comes with facial swelling, your vet may suggest skull radiographs or advanced imaging to evaluate the tooth roots, jaw, and tear duct area. That extra step can change treatment a lot, because recurring eye discharge often will not fully resolve unless the underlying dental or tear duct problem is addressed.

Treatment Options for Eye Infections in Rabbits

Spectrum of Care means you have options. Here are treatment tiers at different price points.

Budget-Conscious Care

$90–$220
Best for: Mild, first-time eye discharge in a rabbit that is still eating well, bright, and without facial swelling or obvious corneal injury.
  • Office exam with eye assessment
  • Basic eye cleaning and home-care instructions
  • Topical ophthalmic medication if your vet feels it is appropriate
  • Recheck if signs are not improving quickly
  • Environmental changes such as lower-dust bedding and cleaner hay setup
Expected outcome: Often good if the problem is a mild irritant or uncomplicated conjunctivitis and treatment starts early.
Consider: Lower upfront cost, but it may miss deeper causes like tear duct blockage or dental root disease. If signs recur, more testing is usually needed.
Most Common

Recommended Standard Treatment

$220–$650
Best for: Most rabbits with persistent discharge, redness, squinting, recurrent symptoms, or suspected tear duct involvement.
  • Full exam with fluorescein stain to rule out corneal ulcer
  • Targeted eye medication and pain control when indicated
  • Tear duct flush if blockage or dacryocystitis is suspected
  • Oral medication if infection extends beyond the eye or tear duct
  • Dental assessment and follow-up plan
Expected outcome: Good to fair, depending on the underlying cause. Many rabbits improve well, but chronic tear duct or dental disease can require repeated care.
Consider: More complete and often more effective than minimal care, but costs rise with procedures, repeat visits, and medications.

Advanced / Critical Care

$650–$1,500
Best for: Rabbits with recurrent one-sided discharge, facial swelling, bulging eye, severe pain, poor appetite, corneal ulceration, or suspected dental root abscess.
  • Sedated oral exam and skull radiographs or CT imaging
  • Culture and sensitivity testing for resistant or recurrent infection
  • Treatment of dental root disease, abscess, or severe tear duct disease
  • Management of corneal ulcer, severe pain, or orbital involvement
  • Hospitalization, assisted feeding, or surgery in complex cases
Expected outcome: Variable. Some rabbits do very well once the root cause is treated, while chronic dental or tear duct disease may need long-term management.
Consider: Highest cost and may require sedation or anesthesia, but it gives the best chance of identifying complicated underlying disease and tailoring treatment.

Questions to Ask Your Vet About Eye Infections in Rabbits

Bring these questions to your vet appointment to get the most out of your visit.

  1. Does this look like simple conjunctivitis, a blocked tear duct, or a dental-related eye problem?
  2. Is there any sign of a corneal ulcer or scratch that changes which eye medications are safe?
  3. Should my rabbit have a tear duct flush, culture, or imaging if this keeps coming back?
  4. Do you see any signs of tooth root disease even if the front teeth look normal?
  5. What home cleaning is safe around the eye, and what products should I avoid?
  6. How soon should I expect improvement, and what signs mean I should come back sooner?
  7. What is the likely cost range for the next step if the first treatment does not work?
  8. Could pain be affecting my rabbit's appetite, and what supportive care should I watch for at home?

How to Prevent Eye Infections in Rabbits

Prevention starts with good daily rabbit care. Keep your rabbit's housing clean, dry, and well ventilated, and use bedding that is low in dust and fragrance. Hay should be fresh and clean, but it also helps to place it in a way that reduces constant poking into the eyes. If your rabbit gets debris around the face often, mention that to your vet.

Diet matters too. Rabbits need a hay-based diet to support normal tooth wear. Because dental disease is a common driver of chronic eye discharge, preventing tooth overgrowth can also help prevent repeat eye problems. Regular wellness visits are useful, especially for rabbits with flat faces, prior tear duct issues, or a history of dental disease.

At home, check your rabbit's eyes and face regularly for tearing, crusting, redness, or fur loss under the eye. Early changes are easier to treat than long-standing ones. Avoid using leftover eye medications or human eye drops unless your vet specifically recommends them, because the wrong product can make some eye conditions worse.
