High myopia as an unusual cause of restrictive motility disturbance.

Endocrine ophthalmopathy is a common cause of restrictive ocular motility disorder associated with abnormal forced duction testing. We report ultrasonographic and computed tomographic findings in a highly myopic patient without thyroid abnormality in whom the restrictive findings of endocrine ophthalmopathy were simulated by contact between elongated globes and the bones of the orbital apices.
