Purpose. To report the ocular findings in patients with hematopoietic malignancy with optic nerve involvement and abducens nerve palsy. Methods. The medical records of all cases of hematopoietic cancer with ophthalmic involvements seen in the Department of Ophthalmology of the National Center for Global Health and Medicine between 2009 and 2014 were reviewed. Results. Eight patients with hemato...

intracranial course. The sixth nerve occupies a superficial position in relation to the fourth ventricle, which communicates directly through the foramina of Magendie and Luschka with the subarachnoid space. Dye studies have shown that agents introduced into the spinal canal frequently reach the medulla, which may explain the peculiar affinity of the sixth nerve to palsy.4 The contrast agents i...

Traumatic unilateral sixth nerve palsy is a relatively rare occurrence, with an estimated incidence between 1% and 2.7% of all head traumas. Bilateral sixth nerve palsies following trauma is even rarer and is often accompanied by additional neurological injury and fractures of the skull or cervical spine. Here, we describe an illustrative case of bilateral sixth nerve palsies following a motor ...

a twelve year old girl, an established case of systemic lupus erythematosus, was referred to us suffering from diplopia and nasal speech for a period of 3 months. neurological examination was conducted which revealed a right-sided sixth nerve palsy and a pulsatile nasopharyngeal mass. neurodiagnostic imaging studies confirmed a giant intracavernous internal carotid aneurysm. the malady of the a...

The abducens is the motor nerve with the most substantial course, both within and outside the brain and it innervates only one muscle. Sixth nerve palsy affords an opportunity to compare recovery after central versus peripheral nerve damage by assessing the dynamics of abduction. Horizontal saccade peak velocities and durations in 14 patients with unilateral peripheral sixth nerve palsies (5 ac...

OBJECTIVE Microvascular decompression (MVD) for hemifacial spasm (HFS) is a safe and effective treatment with favorable outcomes. The purpose of this study was to evaluate the incidence of delayed cranirve ( VI, VII, and VIII ) palsy following MVD and its clinical courses. METHODS Between January 1998 and December 2009, 1354 patients underwent MVD for HFS at our institution. Of them, 100 pati...
