Objective: To determine the types and frequency of symptomatic ocular motility disturbances following head trauma and their association with severity of trauma.
Design: Retrospective study of patients with (1) diplopia unless visual loss is present, (2) heterotropia for far or near targets, and (3) prior head injury.
Setting: Office and in-hospital consulting practice of a university neuro-ophthalmologist.
Subjects: Sixty patients with posttraumatic ophthalmoplegia.
Main outcome measures: Paralytic and nonparalytic heterotropias were quantitated in prism diopters or percentage limitation of ductions. Convergence insufficiency was assessed by determining the near point of convergence.
