Ah, okay, now I found it!
hemianopsia, right? I totally wasn't hearing the "hemi," so it made it really hard to find the word.
I'm using older equipment for this job, but my DH hooked up his good stereo headphones and they are better than my MT headphones (who knew), so things are going more smoothly now. I still needed guidance on this word, though. I just wasn't getting it.
Anyway, thanks a bunch for the help!!
