My pet keeps having eye discharge — could it be Sjögren-like syndrome?

Eye discharge is a common symptom but can have many causes, including tear film problems, infection, or a foreign body. It is best to photograph the discharge and have a vet examine your pet to determine the exact cause before starting any treatment.

What simple steps can I take at home to help relieve the symptoms?

You can gently wipe the area around the eyes and any crusting with a clean, damp cloth moistened with warm water, and prevent your pet from rubbing or scratching the eyes. If symptoms persist or worsen, seek veterinary attention as soon as possible.

What information or materials should I bring to the eye examination?

It helps to bring the date symptoms began, a list of recent medications and known allergies, and close-up photos or short videos of the eyes — these allow the vet to assess the progression of the condition more accurately.

Should I seek immediate veterinary care for red or swollen eyes?

If your pet has copious purulent discharge, keeps its eyes persistently closed, or shows obvious changes in vision, seek veterinary care immediately. For mild redness only, you can monitor briefly and schedule a clinic appointment soon.

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)

•One or both eyes remain completely closed for an extended period
•A large amount of yellow-green pus-like discharge is coming from the eye
•Frequent bumping into objects while moving, suggesting a marked decline in vision

Schedule a clinic visit as soon as possible (within 24-72 hours)

•Persistent red eye with discharge that has not clearly improved
•Continued frequent pawing at or rubbing of the eye with obvious discomfort
•Obvious cloudiness or white spots on the surface of the cornea

01What signs indicate something is wrong?

Red, swollen eyes, discharge, and frequent eye-rubbing are the most common signs of Sjögren-like syndrome in dogs and cats; corneal cloudiness or dry, flaky periocular skin may also be present.

Red eyes, visible blood vessels, or conjunctival congestion
Increased eye discharge that is thick, sticky, or crusted
Frequent blinking or pawing and rubbing at the eyes
Cloudy patches, white spots, or erosions on the corneal surface
Dry, flaky skin around the eyes or abnormal coat texture in the periocular area

Seek emergency care immediately if you notice the following symptoms:

⚠️ Eyes completely closed or the pet refuses to open them
⚠️ Copious yellow-green purulent discharge
⚠️ Obvious vision loss or frequent bumping into objects

02What should you watch for at home? Key observation points and when to seek emergency care

Observing and recording signs at home gives your vet valuable clues; photos and short videos help the clinician assess the situation quickly.

Note when symptoms first appeared and how they have changed over time
Observe whether your pet's alertness and activity level have changed
Track appetite, water intake, and any short-term weight changes
Take close-up photos and short videos of the affected eye (front and side views)
Monitor litter-box or toilet habits and watch for any other whole-body symptoms

03How will the vet diagnose this condition? Common examination steps

The vet will perform a systematic ophthalmic and full-body examination to rule out other systemic conditions that can cause eye symptoms.

Ophthalmic physical examination

assessment of the conjunctiva, cornea, and eyelid margins

Tear film and ocular surface function tests

evaluation of tear production and corneal moisture

Fluorescein staining or slit-lamp examination

detection of corneal damage or ulceration

Blood biochemistry and complete blood count

to rule out systemic disease contributing to eye signs

Advanced imaging (X-ray or CT)

assessment of the orbit, sinuses, and surrounding structures if indicated

04How should the condition be treated and managed after diagnosis? Medications, dietary adjustments, and home care guide

Treatment must be tailored to the underlying cause; medical management and home care go hand in hand, supported by regular follow-up visits and any necessary additional tests.

Follow the vet's instructions for medications or topical treatments and attend scheduled rechecks
If an allergic or immune-mediated cause is suspected, consider dietary and environmental adjustments
Keep the periocular area clean at home and prevent your pet from rubbing or scratching the eyes
Return for regular rechecks to monitor corneal health, discharge changes, and treatment response
Arrange a specialist referral or further imaging when indicated
Contact your vet immediately if symptoms worsen or emergency signs appear

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

Record when symptoms started, how often they occur, and how they have changed

List any recent changes in diet, treats, plants your pet may have contacted, or cleaning products used at home

Compile notes on weight, appetite, water intake, and any changes in urination or defecation

Bring a list of current medications, supplements, and known allergies

Prepare close-up photos and short videos of the eyes to show details that may be hard to observe during the appointment

It is recommended to book a clinic with ophthalmic assessment capability in advance
