Number one rule, imo, don't lead the horse on their blind side. If the horse were to spook away from something on their seeing side, you would be right in the "danger zone" since you're technically invisible to the horse.
It's important to get the horse used to be led/worked with on both sides but I would keep leading on the blind side to when the horse is unlikely to spook (or hold the halter under the chin/be lightly touching the horse at all times, so she knows where you are).
It's the same with lunging/roundpenning, on the blind side, the horse has zero clue where you are so do those things with caution.
Another thing I do with my nearly blind girl (functionally blind in the right eye, very little sight in her left) is I wear my keys on a carabiner attached to a belt loop on my jeans. That way she can always hear me (due to the jingling of the keys) so I don't ever surprise her with my presence and, other bonus of that, it cuts down on how much blabbering I have to do to her since I do use words with her to describe important things and I don't want to make things harder for her that necessary by blabbering along, then suddenly saying an "important" word and expecting her to tune in right at the correct time. With the keys, every word I say has worth and it's therefore easier for her to figure out what's important ie, keys=location of human, words=cues).
Other than that sort of stuff, treat her like a normal horse! Don't chastise her too much for getting into your space on her blind side (cuz, again, she can't see you and doesn't know she's even in your space) and spend a lot of time touching her (at least with my girl, touch is SO important) but treat her normally. Don't baby her because she's "impaired".
