Patch looks a lot like the other Kentucky Derby contenders — he’s a sleek, muscled, 3-year-old thoroughbred. On the left, where others have an eye, Patch has an empty, ping-pong ball-size socket. To correspond to where a horse’s eyes would be located, you would crease the cardboard down the middle, and add two long slots on either side. There are two kinds for equine eyes, Scherrer said. Scherrer has her own one-eyed horse, a former patient, and she initially rode his best friend and led her horse along from the saddle.
