Abstract
- The most common type of ocular miswiring is Marcus Gunn jaw winking phenomenon and Duane's retraction syndrome and the next most common is pseudo inferior oblique overaction. The association of Marcus Gunn jaw winking and pseudo inferior oblique overaction has not been previously reported. The authors describe a 21-year-old woman with both Marcus Gunn jaw winking phenomenon and pseudo inferior oblique overaction. This coexistence in the present case may provide some support to the existing concept that both phenomena are caused by an ocular aberrant innervation. This unusual combination suggests that multiple aberrant innervation patterns can occur in the same patient. The occurrence of ocular miswiring is more common than is indicated by the few reports in the literature.
