I'm pretty much just asking this out of curiousity because this horse has long passed, but it never really was totally figured out.
I used to ride a big QH gelding in his 20s. When I met him, he had a cataract in one of his eyes. Over the years it became foggier and foggier, then slowly started turning in. His face also sunk in on just the one side, over the entire area, but without pain. It looked like this at the end:
The other eye was basically unharmed.
The horse saw a lot of vets, but it was never really totally figured out. I believe they kind of figured that he had a tumor behind his eye, but it didn't seem to cause him any kind of pain. I believe he could see a little bit out of it, but just the smallest bit. It seemed to be worsened by sunlight, so he wore a modified flymask at all times which had an added dark material over that eye to block out extra sun.
It turned out that they could take the eye out and look around, but since he was in his later years and didn't seem in pain the owner decided to let him be.
I'm curious to know if anyone else has ever encountered a situation like his and if they figured out what was happening in there. This old guy was extremely dear to me and I'd still like to know more about what happened.
Thanks so much :-)
I can tell you from experience with several blind horses that once the eye is blind, they no longer move the eyeball and the muscles atrophy and contract, rotating the eyeball into the socket.
Horses can move their eyes independently, whereas most people move their eyes together. A human blind in one eye will track the other one the same way as the sighted eye. But since a horse can't see out of their blind eye they have no reason to move it. The eyeball starts to shrivel sort of, and sucks inwards. Probably natures way of protecting the globe.
But I'm 99% sure he was not fully blind in the eye..could that have happened even just from losing only some sight? Also the sinking in of that side of his face was confusing, it was definitely related.
Sometimes the cause of blindness is loss of innervation to the eye and surrounding musculature which also causes a loss of vascularity. It sounds like maybe that is what was happening. Without being able to examine him, we'll never know the real cause- we can only make guesses. He looks like a real sweet pea though, I bet he was a terrific guy!
He truly was, a total sweetheart.
I am having a hard time seeing what you mean by sunken face......the indent about his eye is completely normal.
His entire cheek is sunken in, basically the entire side of his face lost all of its tone
If you notice around the back of his cheekline or jawline, where it's very bumpy, and how it kind of looks to just go down towards the bottom of his cheek
His other cheek was full and plump and you would not so much definition of the bones
You can see a little bit of a difference in this picture:
But not as clear as seeing him in person. In person it was immediately obvious. It would be a lot of help if I had a picture of his face straight on but unfortunately I don't.
Each side looked like the face of a completely different animal.
Thanks for trying to explain further.....its hard to pick up on the picture.
