Keratitis in Rabbits: Corneal Inflammation, Cloudiness, and Treatment

Quick Answer
  • Keratitis means inflammation of the cornea, the clear front surface of your rabbit's eye. It can make the eye look cloudy, blue-white, red, or watery.
  • Common triggers include corneal scratches, hay or bedding irritation, low tear production, eyelid problems, and infection after eye injury.
  • Rabbits with squinting, a closed eye, thick discharge, a suddenly cloudy cornea, or signs of pain should be seen promptly because corneal disease can worsen fast.
  • Your vet may use fluorescein stain, magnification, tear testing, and eye pressure testing to look for ulcers, infection, or deeper eye disease.
  • Many rabbits improve with topical medication and rechecks, but deep ulcers or severe corneal damage may need referral or surgery to protect vision and comfort.

What Is Keratitis in Rabbits?

Keratitis is inflammation of the cornea, the clear outer layer at the front of the eye. In rabbits, this inflammation often shows up as cloudiness, a bluish or white haze, tearing, squinting, or a painful eye that stays partly closed. Because rabbits have large, prominent eyes and blink less often than many other species, their corneas are more exposed to drying and injury.

Keratitis is not one single disease. It is a description of what is happening in the cornea. In some rabbits, the problem is a superficial scratch or irritation. In others, it may involve a corneal ulcer, deeper inflammation, infection, or scarring. The cornea can also become swollen, which makes the eye look milky or foggy.

This matters because the cornea needs to stay smooth and clear for normal vision. When it becomes inflamed, painful, or damaged, rabbits may rub the eye, stop eating normally, or become less active. Early veterinary care can help protect comfort and reduce the risk of scarring or vision loss.

Symptoms of Keratitis in Rabbits

  • Cloudy, blue, gray, or white-looking cornea
  • Squinting or keeping one eye partly or fully closed
  • Excess tearing or wet fur around the eye
  • Redness of tissues around the eye
  • Eye rubbing with front paws or rubbing the face on surfaces
  • Light sensitivity or avoiding bright areas
  • Mucus or pus-like discharge
  • Visible spot, pit, or defect on the cornea
  • Sudden worsening cloudiness, bulging, or a very painful eye
  • Reduced appetite or quieter behavior from pain

See your vet immediately if your rabbit has a suddenly cloudy eye, obvious pain, a closed eye, thick discharge, a visible corneal defect, or stops eating. Rabbits can hide pain well, and eye disease may progress quickly. Even milder signs like tearing or intermittent squinting are worth a prompt exam, especially if they last more than a day or keep coming back.

What Causes Keratitis in Rabbits?

In rabbits, keratitis often starts with corneal trauma or irritation. A piece of hay, rough bedding, dust, grooming injury, or rubbing at the eye can scratch the cornea. Merck notes that corneal ulceration is the most common eye problem in rabbits, in part because their eyes are prominent and they do not blink as often, so the cornea may be less moist and more vulnerable to injury.

Other causes include low tear production, eyelid or eyelash problems, and conditions that interfere with normal blinking. If the cornea dries out or is repeatedly irritated, inflammation can develop and the surface may break down into an ulcer. Secondary bacterial contamination can then make the problem more painful and harder to treat.

Keratitis may also occur alongside other eye problems, including conjunctivitis, dacryocystitis, deeper inflammation inside the eye, or dental disease that affects nearby structures. In some rabbits, what looks like a simple cloudy eye is actually part of a more complex issue. That is why a hands-on exam matters before choosing treatment.

How Is Keratitis in Rabbits Diagnosed?

Your vet will usually start with a careful eye exam and a full history. They will ask when the cloudiness started, whether your rabbit is squinting or rubbing the eye, and whether there has been any recent trauma, dusty bedding, hay poke, or change in appetite. Because rabbits can develop more than one eye problem at the same time, your vet may also look at the eyelids, tear drainage, teeth, and overall health.

A fluorescein stain is commonly used to check for a corneal ulcer or surface defect. This dye highlights damaged areas of the cornea. Your vet may also use magnification, tear testing, and tonometry to measure eye pressure when it is safe and appropriate. These tests help separate keratitis from other causes of a red or cloudy eye, such as glaucoma or uveitis.

If the eye problem is recurrent, severe, or not healing as expected, your vet may recommend additional workup. That can include culture, imaging, or evaluation for dental disease or deeper eye inflammation. The goal is not only to confirm corneal inflammation, but also to identify the underlying reason so treatment matches the situation.

Treatment Options for Keratitis in Rabbits

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

Budget-Conscious Care

$120–$300
Best for: Mild to moderate keratitis, superficial corneal irritation, or an uncomplicated ulcer in a stable rabbit that is still eating and can be medicated at home.
  • Sick-pet or exotic exam
  • Basic eye exam with fluorescein stain
  • Topical medication selected by your vet, often an antibiotic ointment or drops if an ulcer or surface injury is present
  • Home nursing care, including gentle cleaning of discharge and environmental cleanup
  • Short-term recheck if the eye is improving
Expected outcome: Often good when treated early and rechecked as directed. Many superficial corneal problems improve within days to a couple of weeks.
Consider: This approach keeps testing focused, but it may miss deeper causes such as tear film problems, dental disease, or internal eye inflammation if the eye does not improve quickly.

Advanced / Critical Care

$800–$2,500
Best for: Deep ulcers, rapidly worsening keratitis, severe pain, nonhealing corneal disease, suspected perforation, or cases with possible vision-threatening complications.
  • Referral to an exotics-focused vet or veterinary ophthalmologist
  • Advanced diagnostics, culture, imaging, or workup for underlying disease
  • Intensive medical therapy for deep, infected, or melting ulcers
  • Procedures or surgery when the cornea is at risk of perforation or vision is threatened
  • Hospitalization or very frequent rechecks for severe cases
Expected outcome: Variable. Some rabbits keep a comfortable, visual eye with aggressive care, while others heal with scarring or need salvage procedures to control pain.
Consider: This tier offers the broadest options, but it requires more visits, more intensive home care, and a higher cost range. Not every rabbit needs this level of treatment.

Questions to Ask Your Vet About Keratitis in Rabbits

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

  1. Does my rabbit have keratitis alone, or is there also a corneal ulcer, conjunctivitis, or deeper eye inflammation?
  2. What did the fluorescein stain show, and how deep does the corneal damage appear to be?
  3. What treatment options fit my rabbit's case, and which approach is the most practical for home care?
  4. How often do I need to give the eye medication, and what is the best way to apply it safely?
  5. What signs would mean the eye is getting worse and needs an urgent recheck?
  6. Could hay, bedding, tear duct problems, eyelid issues, or dental disease be contributing to this eye problem?
  7. How much scarring or vision change do you expect if healing goes well?
  8. When should we schedule the next recheck to make sure the cornea is healing?

How to Prevent Keratitis in Rabbits

You cannot prevent every eye problem, but you can lower risk by keeping your rabbit's environment clean, low-dust, and safe for the eyes. Choose bedding with minimal dust, store hay so it stays dry and clean, and watch for sharp enclosure edges or objects that could poke the eye. If your rabbit tends to bury their face in hay, offering hay in a way that reduces direct eye contact may help.

Daily observation matters. Check for tearing, squinting, redness, or a new cloudy look to the eye. Rabbits often hide discomfort, so subtle changes count. Early care is especially important because a small corneal injury can become a more serious ulcer if it is missed.

Routine veterinary visits also help with prevention. Your vet can look for eyelid problems, tear drainage issues, dental disease, or other conditions that may contribute to repeated eye inflammation. If your rabbit has had keratitis before, ask your vet what home monitoring plan makes sense and when a recheck should happen at the first sign of recurrence.
