Locked-in syndrome with bilateral ptosis: combination of bilateral horizontal pontine gaze paralysis and nuclear oculomotor nerve paralysis.

A patient with a classical locked-in syndrome is described, in whom bilateral ptosis was observed on the 2nd day. On the 4th day, ophthalmoplegia was complete with the exception of a voluntary downward movement of the right eye. The syndrome can be explained by the association of bilateral horizontal pontine gaze palsy and a unilateral nuclear oculomotor nerve palsy, and approximates the "total locked-in syndrome".
