Bo's eyes

[velessa]

I'm posting this as a photographic record of just how far from normal the corpora nigra in Bo's eyes are. I had seen these things in horses' eyes before, of course, but I never really noticed or thought about how big his were until the vet pointed it out and I started really taking a look at those of other horses. Here I want to show you a comparison with Glory, one of the Paints I looked at last weekend; she also has a blue eye. After seeing these it definitely makes sense that much of his vision is being blocked out and he probably just kind of sees fuzzy stuff.


First here's Glory, with normal eyes




In this one I've circled the small corpora nigrum she has in this eye


Now let's look at Bo's eyes. These are in daylight without his pupils dilated.

Right








I don't know if you can see the slight variation in contrast, but basically his corpora nigra cover nearly the entire pupils. Here I've circled them:




Here are some more angles of his right eye, this time taken in the dark with his pupils dilated.






And now with the corpora nigrum circled:






Now compare these to Glory's eyes again. Is it any wonder the poor guy has trouble knowing what's coming at him? =(

Thank you for sharing these- maybe that will be useful to someone else at some point too. Poor Bo. It seems so unfair.

Wow! i've never seen anything like that and I've been in horses for 30 years. I would bet, the problem isn't a matter of blurry but rather more like wlking around with a hand in front of your eye where you can only catch small glimpses of stuff. Given the way horse can react to stuff that suddenly appears it's amazing he's not spookier than he is since much of the time it must seem to him as if stuff appears out of nowhere into his very limited field of vision.

My thoughts exactly. I'm astounded he's not much, MUCH spookier than he is and that I've had so few incidents with him.

um. oh dear. liberty definitely has one like what glory has. i've always noticed it but never worried about it bc she doesn't have any problems to speak of. is glory's normal???

[velessa.livejournal.com]

Yeah, hers is what a normal one would look like.

Poor Bo. I noticed Wave's and worried about it, but then I noticed all the horses have them. I didn't really even know what they were.
