This happened back in March, I just haven't gotten around to sharing this story. My sweet little pony Peter got kicked in the eye by one of the other, more dominant horses in his pasture.
It is amazing how well Peter healed himself in just over a week, going from a painful looking eye to normal. For an older pony like him, it's good to know that he is still able to heal himself. We did not use any antiseptics or anything to help it heal or to fight infections, as we risked getting some in his eye and doing more damage. This was all on his own.
