There Is a double blue eye'd horse at my stable. She's only two and her owners are just starting to work with her...But she absolutly freaks out when you even walk over to her left side. I know that blue eye'd horses carry this gene but how can tell that this horse is blind? She's fine on her right side but if you even attempt to ask her to change directions she freaks out quite dangerously. She has had conjunctivitis in both eyes but all the horses were spreading around, and she got over it quickly. Everyone is stumped because she's fine on one side but not the other...? So any tips on how to tell if a horse is blind would be great! Thank!
