Parasympathetic denervation of the iris sphincter muscle in Adie
syndrome results in an enlarged tonic right pupil reacting
poorly to light (A, B). Near response was also
impaired (C). It is supersensitive to cholinergic agents (pilocarpine
0.1%)
(D). Paralysis of the iris results in
characteristic segmental vermiform movements. These are visible
superolaterally acutely
and inferomedially 6 months later
