I have done a eye check. He sees out of both eyes, but is overly reactive to movement on his right. He simply blinks with movement on his left, but jerks his head with movement on the right. He has never been head or ear shy. The reaction is not normal for him.
I also noticed this afternoon a very yellow discharge from his nose. Which very new development.
Thank you all for your help. I took Swazy to the vet and asked him to a head to tail check on him. I also asked him to run a complete blood test on him.
I found out he has the start of uveitis (moon blindness). My vet stated that we caught it really early and we should be able to treat it with no lasting damage. Boy am I glad I took him in. From my research horses can lose the eye sight to it if it is not treat.
I guess this is a good leason for us all. If your horse is not acting normal, take them in and have them checked out. It may be the start of something serious.
