A patient with chronic schizophrenia who had visual hallucinations of
lilliputian nature is described. The authors review the studies on pre
valence of visual hallucinations in schizophrenic patients and suggest
that visual hallucinations may be more common in schizophrenia than p
reviously acknowledged. The authors suggest a routine enquiry about vi
sual hallucination in clinical practice and emphasize the need for fur
ther research under controlled conditions.
