Synergistic Divergence: A Rare Variant of Duaneʹs Syndrome

Purpose: To report and review a rare variant of Duaneʹs syndrome named synergistic divergence and its surgical results. Patient and findings: A 16-year-old girl presented with left face turn and reduced vision in both eyes. Best corrected vision was OD: 3110 and OS: 10/10. There was severe adduction deficiency of the RE with simultaneous abduction of the RE in left gaze. She had XT= 35 in primary position. She underwent subtotal RLR extirpation with a diagnosis of synergistic divergence. XT, abnormal head posture, and simultaneous divergence improved satisfactorily. Conclusion: LR extirpation should be considered in the surgical planning of synergistic divergence. In the present case this procedure satisfactorily improved symptoms.
