Canine and Feline Globe Prolapse (Eye Protrusion)

1 Symptoms

Dogs and cats of any breed can be affected, but short-nosed (brachycephalic) breeds such as Pekingese and Shih Tzu are most prone because their shallow eye sockets offer little protection. In a mild displacement the eye bulges forward and cannot retract on its own; in severe cases the entire globe hangs outside the lids.

The conjunctival blood vessels become congested, and bruising or a collection of blood (hematoma) may appear. After some time the exposed globe looks purple, dry, and shrunken, the pupil narrows, and blood may pool in the front chamber of the eye (hyphema).

The conjunctiva and cornea are often damaged. Left unmanaged, the trapped veins can cause congestive glaucoma, exposure keratitis, corneal death, iritis, retinitis, retinal detachment, lens displacement, and even tearing of the optic nerve.

2 Causes and Transmission

The usual cause is a fight with another animal or a blunt impact that pushes the eye forward out of its socket. Breed conformation — particularly the prominent eyes of brachycephalic dogs — is a major risk factor.

Any event that suddenly raises pressure behind the eye or pulls on the surrounding tissue can precipitate prolapse, so prevention focuses on limiting rough play and trauma to the head and face.

3 Diagnosis

Diagnosis is clinical and based on the visible position of the globe. A veterinarian assesses whether the eye structures are intact and checks the cornea, pupil response, and intraocular pressure to judge how salvageable the eye is.

Because delay worsens the outlook, the eye is evaluated and stabilized as an emergency rather than waiting for extensive testing.

4 Treatment

If the eye structures are intact, the globe should be returned to the socket as soon as possible — the longer it stays out, the worse the prognosis. Mild displacements are replaced under anesthesia and held with tension-relieving sutures at the eyelid.

Severe swelling may require a lateral canthotomy (a small cut at the corner of the eye) to allow repositioning. Anti-inflammatory and antibiotic medication, including corticosteroid eye drops, supports healing and controls infection.

If the trauma is severe and the orbit is already infected or necrotic, surgical replacement is not appropriate and the eye must be removed (enucleation) to protect the animal’s health.

5 Prevention and Home Care

Prevent fighting and rough head play, especially in short-nosed breeds, and supervise interactions with other animals.

If you notice the eye bulging even partially, seek veterinary care immediately to avoid infection and tissue death. While transporting the pet, protect the eye, apply gentle pressure to limit bleeding, and keep the surface moist with a sterile saline-soaked cloth.

After replacement surgery, hospitalized monitoring and an Elizabethan collar help prevent self-trauma, and any prescribed eye medication should be used for the full course.
