Overview
A horse eye injury is an emergency if the eye looks damaged, the horse is in obvious pain, or the injury is getting worse quickly. Eye problems can change fast, so it’s best to take them seriously rather than wait and see.
Some eye injuries are minor surface scratches, but others can involve the cornea, eyelids, or deeper parts of the eye. You can't tell which it is with certainty just by looking, so the safest approach is to check for warning signs and speak to a vet promptly if anything seems off.
Things To Check
1. Look for obvious pain signs such as keeping the eye shut, blinking a lot, rubbing the face, or flinching when you come near.
2. Check whether the eye is cloudy, blue, very red, swollen, or looks different from the other eye.
3. See if there is discharge, bleeding, a cut to the eyelid, or any object stuck around or in the eye.
4. Notice whether the pupil looks unusual, the eye seems sunken, or the horse is squinting more in bright light.
5. Check if the horse is dull, hard to handle, off its feed, or showing signs of a head injury as well as the eye problem.
6. Think about what happened just before it started, such as turnout, a kick, a branch, dust, bedding, or a grooming accident.
7. Watch whether the eye is staying the same, improving, or becoming more swollen or painful over a short time.
Common Causes
The most common causes are scratches to the cornea, irritation from dust or bedding, a minor knock, or a small foreign body like grass seed or grit.
Eye trauma can also involve a cut to the eyelid, a more serious injury to the surface of the eye, or inflammation developing after the initial injury.
Less commonly, what looks like a simple eye injury may be linked to a deeper problem, such as a puncture wound or damage to structures inside the eye.
What To Do
Keep the horse as calm as you can and move them somewhere quiet, with low light if possible.
Do not rub the eye, pull at anything sticking out, or put drops, ointments, or cleaning products in unless a vet has told you to.
If the horse is willing, you can gently observe from a distance and note what you’re seeing, including when it started and whether it is changing.
Keep the area free from dust and try to reduce flies, flying bedding, and other irritants around the horse.
If the eye looks painful, cloudy, badly swollen, bleeding, or the horse is repeatedly shutting it, contact a vet promptly.
When To Contact A Vet
Contact a vet urgently if the eye is closed, badly swollen, bleeding, cloudy, misshapen, or looks like there may be a cut or puncture. You should also call quickly if the horse is very painful, the eye problem is worsening, or you’re not sure whether the surface of the eye is damaged.
Eye injuries can become more serious without prompt treatment, so it’s better to get advice early rather than wait for it to settle.
