Overview
If your horse is rubbing its eye after a suspected injury, it usually means the eye is still sore, irritated or feeling unusual. Common reasons include a scratch on the eye, something stuck under the lid, dust or debris, or swelling around the eye after a knock. Because eye problems can change quickly, it’s worth checking the eye calmly and acting promptly if anything looks or feels wrong.
Things To Check
1. See whether the rubbing started straight after a knock, turnout, grooming or a windy, dusty spell.
2. Look for squinting, keeping the eye partly closed, or obvious sensitivity to light.
3. Check for redness, swelling, discharge, cloudiness or a change in the size or shape of the eye.
4. Notice whether there is any cut, scrape, scab or swelling around the eyelids or face.
5. Watch for tears running down the face, repeated blinking or the horse trying to rub on fences, walls or its leg.
6. If you can do so safely, look for visible dirt, hay, bedding or a lash or hair irritating the eye area.
7. Check whether the horse seems otherwise bright and comfortable, or whether it’s dull, painful or off its feed.
Common Causes
The most common reason is simple irritation after a knock, scratch or dust getting into the eye. A small graze on the cornea can make a horse rub a lot, even if the injury looked minor at first.
Something trapped under the eyelid, such as bedding, grit or a loose hair, is another common cause. Swelling around the eye after a bump can also make the area feel itchy or uncomfortable.
Less commonly, rubbing may be linked to a more significant eye injury, an ulcer, or an infection starting to develop. These can’t be ruled out just by looking from a distance, especially if the eye is cloudy, painful or worsening.
What To Do
Keep the horse somewhere calm and try to stop further rubbing if you can do so safely. A quiet stable or sheltered area may help reduce dust, flies and extra irritation.
Gently observe the eye in good light without touching it unless you’re sure you can do that safely. If there is obvious dirt on the outside of the face, you can carefully clean the surrounding skin with clean water and a soft cloth, but don’t put anything into the eye unless your vet has advised it.
Reduce dusty bedding, avoid turnout in very windy or dirty conditions if possible, and keep an eye on whether the rubbing settles or gets worse. If the horse is still rubbing, or the eye looks painful, cloudy, swollen or closed, veterinary advice is appropriate.
When To Contact A Vet
Contact your vet promptly if the horse is squinting, the eye is cloudy, there’s discharge, swelling is increasing, the eye looks different in shape or size, or the rubbing doesn’t settle quickly. Eye injuries can worsen fast, so it’s best not to wait if you’re unsure.
