If your father has had a complete arterial occlusion and the blood supply was blocked to the retina then, I'm sorry to say, but nothing can be done to restore the function of the retina or give him back his eyesight.

If, on the other hand, some of his vision loss is due to edema in the macula, without complete destruction of this part of his eye then, with treatment for this swelling, there might be something that can be done.

I suggest a consultation with an ophthalmologist, or possibly a retina specialist, so that all of your fathers options can be explored.

Does this make sense to you?
