Brachycephalic Globe Proptosis: A Complete Guide from Emergency Response to Lifelong Eye Care

Eye HealthBreed HealthMeongsiljang Veterinary Advisory Board

Brachycephalic breeds such as Pugs, Shih Tzus, and Pekingese are at high risk for globe proptosis and exposure keratitis due to their shallow orbits and wide palpebral fissures. This guide covers everything from recognizing emergencies to lifelong eye care.

Why Is Eye Care More Important for Brachycephalic Breeds?

Brachycephalic breeds have a shortened muzzle and flattened skull, which results in shallow eye sockets and wider eyelid openings, leaving their eyes more exposed. The most critical concern is that even minor trauma or excitement can cause proptosis, where the eyeball protrudes from the socket. Owners of Pugs, Shih Tzus, Pekingese, Lhasa Apsos, and Bulldogs should definitely learn how to recognize this emergency and how to provide lifelong protective care for their pets' safety.

Eye Conditions Brachycephalic Breeds Must Be Especially Cautious About

Brachycephalic breeds are predisposed to certain eye conditions at significantly higher rates than other breeds due to their unique facial structure. Recognizing early warning signs can help pet owners catch these issues sooner. - Proptosis: A medical emergency in which the eyeball protrudes from the socket. - Exposure Keratopathy: A chronic condition where the eyelids fail to fully cover the eye, causing the cornea to dry out and become damaged. - Corneal Ulcer: A condition characterized by deep lesions on the cornea caused by friction, dryness, or trauma. - Keratoconjunctivitis Sicca (Dry Eye): A condition resulting from insufficient tear production, leading to ocular dryness. - Entropion and Ectropion: Conditions where the eyelids roll inward or outward, causing eyelashes to irritate the cornea.

In What Situations Does Globe Proptosis Occur?

Ocular proptosis is the most common and most frightening emergency eye condition in brachycephalic breeds. Clinical data show it is most frequently reported in Shih Tzus, Pugs, and Lhasa Apsos. The common scenarios leading to this condition can be summarized as follows: - Neck pressure: When the leash is pulled tightly or the dog is lifted by the neck - Facial trauma: Fights with other dogs, falls, or vehicle impacts - Excessive excitement or struggling: Forceful restraint during grooming or bathing - Direct facial impact: Collisions with furniture corners or doors Ocular proptosis is mostly caused by trauma. Once the eye protrudes, it is often trapped by the swollen tissues around the eye, a condition known as "secondary entrapment," making it difficult for the eye to return to its normal position on its own. Additionally, if the extraocular muscles are torn (multiple extraocular muscle avulsions), the cornea or sclera is ruptured, or anterior chamber hemorrhage occurs, the prognosis worsens. Therefore, it is crucial to seek treatment as quickly as possible without delay.

Globe Proptosis — The Golden Time Is Within 1 Hour

If you notice your dog’s eyeball protruding from the eyelids, take them to a 24-hour emergency veterinary clinic immediately. The sooner surgical repositioning is performed, the higher the chance of preserving vision, so it’s crucial not to delay and to head straight to the clinic. On the way, keep the surface of the eye moist by gently applying sterile saline solution or artificial tears with clean gauze (avoid non-sterile tap water, as it poses a contamination risk even in emergencies). Never attempt to push the eyeball back into place with your hands, and prevent your dog from rubbing their eye by fitting them with an Elizabethan collar or lightly covering the area with a towel.

How Is It Treated at the Veterinary Clinic?

At the clinic, we first stabilize the pet’s overall condition and address any life-threatening injuries before proceeding with ophthalmic treatment. The process generally follows these steps: 1. Systemic evaluation: Check for shock, fractures, or concussions. 2. Corneal protection: Flush the surface with saline and apply antibiotic eye drops. 3. Reduction under general anesthesia: Incise the swollen eyelids to reposition the eyeball back into the orbit. 4. Temporary eyelid suturing (tarsorrhaphy): Suture the eyelids partially closed for a period to protect the eye. 5. Decision on enucleation: If severe damage to the extraocular muscles, corneal rupture, or optic nerve severance is confirmed, removal of the eyeball is recommended. Your veterinarian will assess the extent of the injury and inform you about the likelihood of preserving vision.

Post-Suture Recovery Care

Temporary eyelid suturing (temporary tarsorrhaphy) to protect the eye after corneal surgery is typically maintained for about 10 to 14 days, and the total recovery period varies depending on the severity of the injury. Proper care during this period is crucial for preserving vision. - Maintain sutures: Do not remove or touch them arbitrarily (usually removed by the veterinarian after 10–14 days). - Strictly follow eye drop schedule: Administer antibiotics and artificial tears regularly as prescribed by the veterinarian. - Wear an Elizabethan collar 24/7: Prevents rubbing and scratching. - Limit walks: For 1–2 weeks, restrict to short bathroom-only walks. - Adhere to recheck appointments: For suture removal and corneal healing assessment. Even after recovery, some dogs may experience residual effects such as eyelid paralysis, exposure keratitis, dry eye (keratoconjunctivitis sicca), or decreased vision, making regular ophthalmic examinations necessary.

Lifelong Eye Protection Care — Owner Daily Routine

Brachycephalic breeds are prone to severe eye injuries that are difficult to treat once they occur, making daily prevention essential. Here’s a routine for pet owners to follow daily and weekly: - Use a harness: Opt for a chest harness instead of a collar to avoid pressure on the neck. - Supplement with artificial tears: Apply 1–2 times daily in dry environments. - Clean around the eyes: Wipe away discharge and loose hair daily using saline-soaked gauze. - Trim facial hair: Regularly trim long hairs that may poke into the eyes. - Regular veterinary eye exams: Schedule check-ups every 6–12 months, including fluorescein staining and tear production tests. - Safe playtime: Avoid roughhousing or chasing in confined spaces.

Stop Walks and Play in These Situations

On hot days, vigorous walks while your dog is excited can lead not only to breathing difficulties but also to increased intraocular pressure and conjunctival redness. Rough play with other dogs, sharp turns in narrow passages, and sudden corrections on roads with cars or bicycles also increase the risk of globe proptosis. It’s safest to avoid the hottest parts of the day and to make sure everyone in your household knows not to pull or tug on your dog’s head or neck.

Frequently Asked Questions About Brachycephalic Eye Care

Do brachycephalic breeds inevitably experience at least one episode of exophthalmos during their lifetime?

Not necessarily. While the structural risk is higher, many dogs never experience any issues if you consistently use a harness, prevent injuries, and keep up with regular check-ups. However, since the likelihood of problems is still greater than in other breeds, it's important to know how to handle emergencies.

Will vision recover if the eye becomes protruded?

If reduction is performed as soon as possible after discovery, and if the pupillary light reflex (PLR) remains intact, there is minimal globe displacement, and damage to the extraocular muscles and optic nerve is limited, there is a possibility of preserving vision. However, if multiple extraocula

Is it safe to use artificial tears every day?

Preservative-free artificial tears are generally safe for supplemental eye drops. However, if a tear secretion test indicates dry keratoconjunctivitis, a separate prescription eye drop medication may be necessary. Please consult with your veterinarian to determine the appropriate dosage and frequency of administration.

Which harness is best for walks?

Brachycephalic breeds should avoid any pressure on the neck, so an H-shaped or Y-shaped harness with a D-ring on the chest is recommended. Avoid designs with thin straps or those that sit too high on the neck, and adjust the fit so that two fingers can comfortably slide underneath to ensure easy breathing.

When should I start getting my pet regular eye check-ups?

After the initial basic eye exam at six months of age, annual check-ups are recommended starting from one year old. If you notice signs such as eye rubbing, changes in tear color, or an increase in eye discharge, it’s safest to seek veterinary care immediately, regardless of the regular schedule.
