Abstract :
Synergistic divergence (SD) is a rare congenital ocular motility pattern, characterized by paradoxical abduction
during attempted horizontal gaze to the contralateral side. SD is generally unilateral and always associated with
limited adduction of the affected eye. The present study introduces a case report on a bilateral congenital adduction
palsy with synergistic divergence. The case was a ten year old boy with a unique case of synergistic divergence and
normal monocular movement, which has not been documented before. The case was a Middle Eastern ethnicity,
referred to the ophthalmology clinic in Ahvaz Imam Khomeini Hospital, Ahvaz, Iran with complaints of eyelid
drooping, squinting and abnormal eye movements of both eyes. The study presents the findings of complete
orthoptic and ophthalmologic examinations including dilated fundoscopy.
