I don't know anything about those things in your diagnosis, but it seems to me that vision troubles of that level of significance would be likely to contribute to anxiety.
If you didn't know who people were, and couldn't read their faces before they got within three feet of you, it would likely be frightening. Someone prone to anxiety would not be at all out of line in deciding to ascribe terrible motives to people by default -- who knows what those people are up to, I'm going to assume the worst, just in case. And it seems reasonable to make monster noises at them and run and hide, in self defense.
