Proptosis of the Eye – When Your Dog’s Eye Pops Out!
Eyes are beautiful, truly unique, and colorful.
Unfortunately, accidents involving the eyes happen. One of the more common mishaps
is proptosis of an eye. This week I’m sharing information about this unique
problem to help raise awareness. I hope you find the post insightful and
helpful. Happy reading!
Proptosis – What is it?
Proptosis is the term used to describe a scenario in which the eyeball moves forward beyond the borders of the eye socket and eyelids. In fact, the eyelids get stuck behind the globe, thus preventing the eyeball from returning to its normal position. The abnormally exposed eye subsequently becomes inflamed and dry, often resulting in ulcers of the cornea.
Proptosis of the eye is most commonly caused by trauma, most
commonly motor vehicle accidents, animal fights, choking accidents, and
aggressive scruffing. Small brachycephalic (flat-faced) dogs are
over-represented since they have naturally prominent eyes. There is no age or
Proptosis – What does it look like?
As mentioned earlier, the globe extends forward beyond the
borders of the eye socket. The conjunctiva is typically reddened and swollen.
Blood may be present in the anterior chamber of the eye (the area between
cornea and the iris). The cornea may be discolored, and the muscles that
control eye movement are often torn.
Proptosis – How is it diagnosed?
Diagnosis of eye proptosis is straightforward and based on
the appearance of the globe protruding out of the eye socket. Given proptosis
is often the result of trauma, a veterinarian will perform a thorough physical
examination in an attempt to identify other injuries. Blood and urine, as well
as diagnostic imaging tests, may be recommended to evaluate the health of major
Proptosis – How is it treated?
Proptosis of the eye is considered a surgical emergency. Given this condition is typically the result of a traumatic accident, patients must be appropriately stabilized prior to anesthesia, potentially necessitating a delay of surgery. The severity of the proptosis and the length of time to surgery dictates the type of surgical intervention. Those without severe injuries may be treated by a veterinarian replacing the eye in the socket. The doctor temporarily closes the eyelids via a procedure called a temporary tarsorrhaphy and prescribes ophthalmic antibiotics and multimodal pain medications. See the video below to watch this procedure.
A veterinarian will often treat severely damaged eyes (or
patients for whom surgery had to be delayed due to a need for stabilization) via
surgical removal of the globe (called enucleation). The eye and orbit tissues
are removed, and the eyelids are permanently sewn closed. Prognosis for vision
is always poor. Patients who have surgery within a couple of hours of the accident
have the best chance for having their vision saved.
The take-away message about proptosis in dogs…
Proptosis of the eye is a common ophthalmic injury most often
due to a traumatic accident. Although prognosis for vision is always poor, stabilization
and timely surgery are the best strategies for potentially saving vision.
