Yes, exactly! I didn't mean there were peripheral abnormalities, rather
an abnormality in the higher-level processing of sensory information,
although re-reading what I wrote, I realise this may not have been
clear. My original point was that abnormalities of visual perception did
not necessarily imply abnormalities of the peripheral apparatus of
vision. Similarly the raised pain threshold does not imply peripheral
sensory disturbance.
