"A scotoma is a blind or blank spot in the visual field. " Oh, I've had those - though not as lasting or opaque as they sound for you. I always thought it was one step prior to the "blinding" pain level I'll get from different nerve compression syndromes and injuries I have/had; for obvious reasons I try to manage my life to limit agitating the nerves and to not reach the blinding pain level - where for at least a few moments I can't see or don't experience anything but the pain; quite the short circuit mechanism to grab one's full attention.
