[A case of Duane's syndrome with ocular melanosis]

Duane's syndrome has various ocular and systemic abnormalities. We report a Duane's syndrome patient with ocular melanosis. Duane's syndrome has many complications, but ocular melanosis has never been reported previously. It is possible that there is a similar mechanism between the ocular melanosis and misdirection of the oculomotor nerve to the external rectus in this case, but it is more probable that it is simply coincidental.
