Tension or “Worry Wrinkles” Above the Eye
Look at the signal, then look at the whole horse and the situation around it.
NOTICE
Wrinkles or muscle tension above the eye look more noticeable than usual.
The area may appear tighter, more angled, or more drawn than it normally does for that horse.
WHAT IT MAY TELL YOU
Tension above the eye can show up with pain, increased tension, or heightened arousal.
The familiar phrase “worry wrinkles” can be a useful visual description, but it should not be treated as a direct translation of what the horse is feeling.
DON'T ASSUME
Eye wrinkles don't automatically mean the horse is worried, frightened, or in pain.
Instead, ask: “Is this different from the horse's normal face, and what else is happening?”
LOOK AGAIN
Compare the area above the eye with the horse's usual expression. Notice whether you also see tightening around the eye, tension in the mouth or nostrils, changes in ear position, or more tension through the body.
Then think about what happened just before the expression changed.

What research suggests
Tension above the eye is included in equine pain assessment. Research on eye wrinkles has also found some changes across different emotional conditions.
What that does not mean
The evidence does not support using wrinkles as a simple “worry meter.” Studies have found mixed results, and individual differences can affect how wrinkles appear.
