A horse's vision is an extremely important sense. Their range of vision allows them to see all around except directly in front or back. But even blind horses can adapt if they feel safe and secure. It's very important to keep a blind horse in a fenced-in area. Make the sure fence is injury-proof in case the horse bumps into it. Check the enclosure and keep anything away that might cause the horse to panic and run. Don't startle the horse and speak softly when approaching or if nearby. Water, feed, the salt block, should always be in the same place. If the horse has a friend horse, it will often adopt the blind horse and protect him/her. For your safety and the horse's use the same methods of communicating and be consistent.
