Acquired torticollis due to an ocular surface foreign body.

Ocular torticollis is traditionally attributed to eye misalignment, nystagmus, ptosis, or refractive error. We present 3 pediatric cases of acquired torticollis caused by a foreign body beneath the upper eyelid. The head posturing presumably developed to minimize contact of the foreign body with the corneal surface and mitigate ocular discomfort. Torticollis resolved in all cases after removal of the foreign bodies. These cases demonstrate that acquired torticollis in a child can be a clinical sign of an ocular surface foreign body.
