Bilateral cerebral ptosis.

We studied 13 patients with bilateral ptosis after acute right frontotemporoparietal lobe lesions. All patients had conjugate gaze deviation to the right. The ptosis persisted for about 5 days in five patients, or was still evident at the time of discharge or death. Other cranial nerve findings included lower facial weakness in five patients and both upper and lower facial weakness in eight patients. The transience of cerebral ptosis and conjugate gaze disturbance may imply ability of the intact hemisphere to assume control.
