title: Restrictive strabismus in Parry-Romberg syndrome.
abstract: Forced duction and generation testing of a patient with Parry-Romberg syndrome (progressive hemifacial atrophy) confirmed that his incomitant hypotropia and esotropia were restrictive and not due to nerve paresis. This suggests that an orbital inflammatory process (causing extraocular muscle fibrosis) is part of this rare and poorly understood syndrome.
