Well I'm happy.
This boarder that I have has had horses for 6 years and not one time has she had a horse checked by a vet for anything. So this little eye problem was quite the blessing, IMO.
The vet did a full exam, dyed the eye and concluded that she likely had a bee sting which contributed to the swelling. He saw fluid in the eye and she did have a light scratch on her eye so he gave an antibiotic cream. He went against giving a cortizone shot because he said that while those help with pain and discomfort, it can lengthen the healing time. That was something I didn't know...
He also grilled my boarder about her horse's breathing problem.
He said she has an obvious heave line and you can hear her struggling to breathe. He informed her that there is an additive you can get for their feed that is basically sudafed. He can provide it monthly but she just has to pay for it and pick it up.
I think my boarder got a good understanding of just how important vet care is...both maintenance, preventative and general care. So I was happy to have that finally "click" for her. And the horse got some much needed attention that she has been needing for quite awhile now.
As of this morning, there is still some light swelling and the cloudiness has almost gone away. She just has a small spot towards the back of the eye.
