rabbit eye discharge and runny eye, SG troubleshooting

updated 13 May 2026

eye discharge in rabbits is a sign that needs investigating, not waiting out. rabbits hide pain so well that visible eye issues often indicate the problem has been developing for days. this guide walks through what the discharge looks like, what causes are most likely in SG, and when to head to the vet.

the at-home assessment

before vet, observe:

1. one eye or both?

one eye usually points to a localised cause (foreign body, corneal ulcer, dental root abscess on that side). both eyes points to systemic causes (infection, allergy, environmental irritant).

2. what colour and consistency?

  • clear, watery, intermittent — often blocked tear duct, mild irritation, early stage
  • white, milky, sticky — bacterial infection
  • yellow or green, thick — established bacterial infection, possibly severe
  • bloody or brown — trauma or advanced infection, emergency
  • mucus-like, stringy — allergic or chemical irritation

3. is the eye itself looking different?

  • redness in the eye membrane — irritation or infection
  • cloudiness over the eye surface — corneal damage
  • bulging or protrusion — emergency, likely a serious internal issue
  • one pupil different from the other — possible neurological or eye-pressure issue

4. is the rabbit’s behaviour normal?

  • eating, drinking, droppings normal? then less urgent
  • eating poorly, hunched, hiding? more urgent

the four most common causes in SG

1. blocked tear duct (nasolacrimal duct obstruction)

the duct that drains tears from the eye to the nose can become blocked, especially in dwarf and lop breeds with their flatter face structure. tears overflow onto the face, causing the chronic “wet cheek” appearance.

signs:

  • clear, watery discharge from one or both eyes
  • fur staining (brown) below the eye
  • worse during stress or temperature changes
  • otherwise normal behaviour

treatment: vet flushes the duct under mild sedation. some cases need repeated flushing. SGD 100-250 per procedure depending on clinic.

2. corneal ulcer or scratch

physical damage to the eye surface, often from a hay strand, scratch from a cage corner, or play injury. common because rabbits often poke their eyes into things.

signs:

  • one eye affected
  • watery discharge initially, can become thicker
  • the eye stays partially closed (squinting)
  • light sensitivity (rabbit retreats from bright spaces)
  • visible scratch or cloudiness on the eye surface

treatment: ophthalmic ointment for 7-14 days. healing is usually complete if caught early. requires vet diagnosis to confirm not deeper damage.

3. dental root abscess presenting through eye

rabbit tooth roots extend toward the eye socket. an abscessed molar root can drain through the tear duct, presenting as chronic eye discharge.

signs:

  • thick yellow or white discharge from one eye, persistent
  • other dental signs (drooling, weight loss, selective eating)
  • possible swelling of the cheek or jaw
  • standard antibiotics for “eye infection” not improving the symptom

treatment: dental imaging required (X-ray or CT). often requires extraction of the affected tooth. SGD 800-2500 for the full procedure including hospitalisation.

4. allergic/irritant reactions

dust, smoke, cleaning products, aerosols. clear watery discharge from both eyes, no other systemic signs.

treatment: remove the irritant. eye irrigation with saline. usually resolves within 1-3 days.

the SG-specific notes

three things particularly common in SG:

haze season effects. during haze, fine particulates irritate rabbit eyes. some sensitive rabbits develop watery eyes that resolve when air quality improves. see our haze guide.

aircon allergic reactions. rabbits in continuously AC’d rooms can develop dry eye, which can cycle into infection. balance AC use.

lop breed predisposition. Holland Lop, Mini Lop, and similar have higher tear duct issue rates because of facial structure. see our Holland Lop guide.

when it’s an emergency

go to the vet same-day if you see:

  • bulging eye (one eye protruding more than the other)
  • bloody discharge
  • significant swelling around the eye
  • the rabbit is rubbing or pawing at the eye constantly
  • combined eye discharge plus loss of appetite or lethargy
  • cloudy patches or significant vision impairment

these all suggest urgent issues that worsen quickly.

at-home interim care

before vet:

  • gently wipe discharge from the area with a damp cloth (boiled then cooled water, no antiseptic)
  • do not apply any eye drops or ointments without vet direction (some human eye products contain ingredients toxic to rabbits)
  • keep the rabbit’s enclosure clean and dust-free
  • handle gently — avoid contact near the affected eye

the cost reality

eye conditions can be cheap to fix or expensive depending on cause:

  • blocked tear duct flush: SGD 100-250
  • corneal ulcer treatment: SGD 150-300
  • bacterial conjunctivitis: SGD 100-200
  • dental root abscess treatment: SGD 800-2500
  • complex internal eye issues: SGD 500-2000+ depending on diagnostics

the difference is the underlying cause, not the eye treatment itself. early vet visit usually keeps costs at the lower end because the underlying issue gets caught early.

what owners often get wrong

three patterns:

  • using human eye drops like contact lens solution or saline drops. some are safe, many aren’t. always vet first
  • waiting 2-3 weeks to see if it clears up. by then, infections can be deeply established
  • treating the eye symptom and missing the dental cause. chronic eye discharge that doesn’t respond to antibiotics is dental until proven otherwise. ensure the vet imaging includes the head
