It may be some days before
relatives or nursing staff
stumble onto the fact that the patient
has actually become sightless.
The patient ordinarily does not
volunteer the information
that he has become blind,
but he furthermore misleads
his entourage by behaving
and talking as though he were sighted.
Attention is aroused, however,
when the patient is found to collide
with pieces of furniture, to fall
over objects, and to experience
difficulty in finding his way around.
He may try to walk through a wall
on his way from one room to another.
Suspicion is still further alerted
when he begins to describe people
and objects around him, which,
as a matter of fact, are not there at all.
