I just got a call from the owner. I need to go look at Sarah Lee. She said she got poked by something, maybe a thorn above her eye and it was bleeding. She says it isn't the eyeball itself and doesn't think anything still in there and "at this time " we may not need to call the vet but wants me to see what I think. Getting dressed. Anything particular I should look for?
Cuts and things near the eye need to be looked at more carefully than the same cut somewhere else. Clean it out really good, treat it with antibiotic topical so it doesn't get infected, and take the judgment of the stable owner... she's seen more injuries than you have, and probably has a good feel for which ones need to be vetted. If it's debatable either way, you may want to err on have it vetted just so there is no infection, and it gets sutured if necessary, because no one likes for there to be ugly scars on a horse's face.
Take pictures.
I'm late getting on - please update. If it's a puncture wound, keep it open.
