My beautiful Appy mare has been blind from uveitis for 8 years, she is now 28. She went blind in both eyes within weeks of her diagnosis despite aggressive treatment. She adjusted very well almost immediately. She is pasture-kept and has companions. She is nervous with the other horses if she thins they might come after her (food or whatever) but otherwise she is happy and comfortable, fat and affectionate. She has gotten into a few muddles but never injured herself. She also gets the run of the property most of the day now that grass is in.
It all depends on the individual horse. My mare was such a wonderful riding horse in her time that I owed it to her to maintain her, but she was much younger when this happened.
Certainly at 34 no one would fault you for putting him down but you need'nt assume he won't be comfortable and able to enjoy a little more time on the planet, once he adjusts.
*I forgot to add she wears a fly mask all the time during the day, to keep flies out of her eyes and also to keep the sun out, as horses with uveitis are sensitive to light. You can make or buy masks with felt panels to totally block the sun, too.
