Just love every update on this guy!
When I volunteered at a therapy barn in North Carolina many years ago, they had a retired eventer who was completely blind (appy mare who had moonblindness)- one eye had been removed, the other had no vision. She was still an amazingly trustworthy therapy horse, and taught many small kids how to ride. She had been so fiercely competitive during her show days, I don't think she would have been ok without a job. She had a "seeing eye pony" with her in the fields, but was great in the ring or on trails for lessons.
