What can cause eye proptosis in dogs and cats?

Eye proptosis is commonly caused by ocular trauma, orbital masses, or eyelid and eye infections; sometimes it is related to congenital anatomy or tumours. The specific cause needs to be confirmed by a vet through examination and imaging — please bring your pet in for an assessment.

Does eye proptosis always require surgery?

Not necessarily. Whether surgery is needed depends on the cause and severity of the proptosis. Mild or reversible cases may be managed conservatively. Your vet will recommend the best approach based on examination findings — please follow their advice.

Is there a chance of vision recovery after surgery?

The likelihood of vision recovery depends on the severity of the injury and the timing of treatment. Some cases may achieve partial recovery, while others may not fully recover. Post-operative follow-up is important — please discuss the prognosis with your vet.

How do I care for an eye with proptosis at home?

Home care should follow your vet's instructions — this may include using a protective eye shield, keeping the eye area clean, and attending scheduled follow-up appointments. Avoid self-medicating or putting pressure on the eye; contact your vet promptly if anything seems off.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek immediate veterinary care (emergency)

•Heavy bleeding from the eye that cannot be stopped at home
•The eyeball is clearly protruding with exposed tissue
•Sudden complete lack of response to light and not tracking objects

Schedule a veterinary appointment soon (within 24-72 hours)

•Eyelid swelling that prevents the eye from closing completely
•Pulls away when the eye is touched and continues to show discomfort
•Intermittent blood-tinged discharge or a small amount of bleeding

01What symptoms indicate a problem?

Eye proptosis refers to the forward displacement of the eyeball, often accompanied by pain, tearing, redness, swelling, or vision changes. Below are signs owners can easily observe and emergency warning signals to watch for.

Eyeball visibly protruding or changed in appearance
Persistent bleeding or blood-tinged discharge from the eye
Swollen eyelids, possibly unable to close completely
Flinching or visible discomfort when the area around the eye is touched
Suspected vision changes, light sensitivity, or failure to track moving objects

Seek emergency care immediately if you notice the following symptoms:

⚠️ Heavy bleeding that cannot be controlled at home
⚠️ Obvious deformation of the eyeball or exposed tissue
⚠️ Sudden complete loss of response to light

02How to assess the situation at home? Key observations before your vet visit

Before heading to the vet, you can observe and record information at home that will help with diagnosis and give the vet a clearer picture of how the condition started and progressed.

Note the time of onset, initial circumstances, and any history of trauma
Observe changes in alertness, appetite, and water intake
Record changes in elimination habits, activity level, and behaviour
Take close-up photos and videos of the affected eye with your phone for reference
If bleeding is present, note the volume, colour, and frequency
Bring all records and images to the consultation for the vet to review

03How will the vet make a diagnosis? Common diagnostic tests

At the clinic, the vet will perform an ophthalmic and full physical examination, and may order imaging or laboratory tests to identify the cause and determine the best course of treatment.

Physical ophthalmic examination

assessment of appearance, cornea, eyelids, and visual reflexes

Blood and biochemistry panel

evaluation of overall health, infection, or metabolic issues

Urinalysis

to rule out systemic disease or metabolic abnormalities

X-ray or orbital imaging

assessment of bone structure or changes to the orbit

CT scan or advanced imaging

to clarify deep orbital tumours or the extent of trauma

04How is the condition treated after diagnosis? Medications, diet, and home care guide

Treatment depends on the underlying cause and severity, and may include medical management or surgical intervention. Close follow-up and careful nursing are required during and after treatment.

Infections or inflammation are often managed with antimicrobial or anti-inflammatory medications
Severe trauma or recurrent proptosis may require surgical intervention
Regular follow-up visits and imaging are needed during and after treatment
Medications and care plans are adjusted based on blood work or imaging results
If a concurrent chronic condition is present, dietary and lifestyle management may be recommended

05What to prepare before the vet visit? Key information to help the vet identify the cause quickly

Bring a detailed log of the onset time and how symptoms have changed

Prepare notes on recent changes in diet, elimination, and behaviour

List all current medications and supplements

Bring any previous test reports or imaging files (if available)

Use a secure carrier and bring photos and videos of the eye for reference

When booking, mention whether eye trauma is suspected or whether imaging will be needed
