What is it called if the brown part of the eyeball is small or smaller that what you think it should be? As in the entire eyeball that shows from the face and there is more white than one usually sees. Not talking cancer or cataracts just an anomoly. I have seen other horses with this and the vet has looked at my mares eyes. But I always passed horses up with this. But i totally fell for this girl and bought her in April.SHe has been wonderful!!! When i bought her she had a 21 month old foal at her side (yes you read that right).ANyway her foal had the same eyes. My mare is a grye and white pinto/arab. SHe has a HUGE white face almost bald. But her son was just a solid bay with the same small brown on his eyes.So is it a painti pinto thing? I don't think so.Is it an inheritable trait as her son had them also? Does ANYBODY know what I am talking about??
