Hello Health Gurus, i'm posting a pic of my mare Chloe's eye, her right one. Only because of this huge brown spot in it, I can't remember what it is called, but I think it may affect her vision to an extent. She only spooks on her right side, especially if i'm riding. If it helps she is a Mountain Pleasure horse, double dilute black = Smoky Cream, if her color would have anything to do with it. Any thoughts on what could have caused it, and if it will get worse/better in time? Your help is much appreciated!! Thank you!
