Eye Injury
Damage to a pet's eye from scratches, debris, or trauma that can quickly worsen and threatens vision without prompt veterinary care.
Also known as Corneal Ulcer, Corneal Abrasion, Scratched Eye, Eye Trauma
A pet's eye can go from mildly irritated to seriously damaged in a matter of hours, which is part of what makes eye injuries so easy to underestimate. They can happen in all kinds of ordinary ways: a scratch from a housemate cat during play, a stray branch on a walk, a foreign bit of grass seed or dust that gets trapped under the eyelid, or a knock from blunt contact like a ball or another animal's paw. Because the surface of the eye, the cornea, is only about half a millimetre thick in dogs and cats, even small scrapes can turn into deeper wounds if they're not caught early.
The clearest sign something is wrong is a change in how the eye looks or how your pet uses it. Watch for squinting or holding the eye shut, redness or a bloodshot look to the white part of the eye, unusual tearing, or discharge that's green or yellow rather than clear. A cloudy or bluish haze over the normally clear surface, pawing at the face, or head-shyness on one side can also point to an injury underneath the surface. Any bleeding from the eye, or an eye that looks like it's bulging or sunken, is a sign of a more serious injury and needs same-day emergency care.
One of the most common outcomes of a scratch or scrape is a corneal ulcer, essentially an open wound on that thin outer layer of the eye. A superficial ulcer often heals quickly with the right treatment, but if it becomes infected or goes untreated, it can deepen into the tissue below, and in the worst cases progress to a condition where the cornea softens and thins to the point of rupture. Flat-faced (brachycephalic) breeds such as pugs, Shih Tzus, and Pekingese have prominent eyes that make them more prone to this kind of injury. Vets typically confirm an ulcer using a harmless orange dye called fluorescein, which glows green under a special light wherever the surface has been broken.
What makes eye injuries different from many other minor wounds is how quickly a small problem can escalate and how much is at stake. A scratch that looks trivial today can threaten your pet's sight within days if the wrong bacteria take hold or the wound doesn't heal cleanly. Never reach for human eye drops or ointments at home, since some ingredients that are fine for people can actually worsen certain pet eye conditions. If you notice any of the signs above, the safest move is always a same-day vet visit rather than a wait-and-see approach, since the guides and clinics listed below can help you figure out exactly what type of care your pet needs and how urgently.
