A 50 year old man developed tonic-clonic seizures while receiving cyclosporin A after orthotopic cardiac transplant. The seizures resolved after cessation of cyclosporin A. Thirteen months later, he developed diplopia from bilateral internuclear ophthalmoplegia while receiving intravenous FK506. A temporal association was found between his symptoms and the serum FK506 concentrations. Withdrawal...

Brainstem strokes affecting the periaqueductal gray matter of the midbrain can cause vertical ophthalmoplegia. Accompanying clinical features are frequently associated and reflect the involvement of other brainstem structures. We report on an adolescent presenting with vertical gaze palsy and left mydriatic pupil as the only clinical expression of a small infarct located in the left periaqueduc...

Wall-eyed monocular internuclear ophthalmoplegia (WEMINO) with contraversive ocular tilt reaction has not been previously reported. A 71-year-old woman suddenly developed blurred vision. Examination revealed left internuclear ophthalmoplegia, left exotropia, right hypotropia, and rightward head tilt. Magnetic resonance imaging showed a tiny infarction at the area of the left medial longitudinal...

Orbital apex syndrome (OAS) is a rare disease that presents with a complex of symptoms, including ophthalmoplegia, ptosis and visual loss. Due to the poor prognosis, making a prompt diagnosis and administering the appropriate treatment must be initiated without delay if OAS is suspected. We report here on a case of a patient with sphenoid fungal balls, and he presented with acute visual loss an...

Article abstract-To determine the significance of serum anti-GQlb IgG antibody, we studied the disease spectrum associated with this antibody and GQlh epitope in the human nervous system. We examined sera from 19 patients with typical Miller Fisher syndrome (MFS), five patients with acute postinfectious ophthalmoplegia without ataxia (atypical MFS), six patients with Guillain-Bad syndrome (GBS)...

OBJECTIVE To derive a reliable estimate of the frequency of pupil involvement in patients with diabetes-associated oculomotor nerve palsy. PATIENTS AND METHODS In this prospective study, standardized enrollment criteria were employed to identify 26 consecutive patients with diabetes-associated oculomotor nerve palsy who were evaluated in a referral-based, outpatient neuro-ophthalmology practi...

Internuclear ophthalmoplegia is a rare condition caused by injury to the medial longitudinal fasciculus in the brainstem. It usually occurs in conditions such as stroke or multiple sclerosis and is extremely rare after head injury. We report a case of unilateral internuclear ophthalmoplegia, which occurred after a minor head injury in a young male. His only symptoms were headache and diplopia. ...

Only a few cases with unilateral internuclear ophthalmoplegia have been reported presenting vertical nystagmus, and few of them provides convincing evidence for the paramedian tract neuron to be a vertical neural integrator. We report a patient who suffered from confined dorsal mid-upper pontine infarction showing unilateral internuclear ophthalmoplegia with upbeat nystagmus in primary position...

Bickerstaff's brainstem encephalitis is characterized by ophthalmoplegia, ataxia, and disturbance of consciousness. It is similar to Miller Fisher syndrome, a variant of Guillain-Barre syndrome, in that they share features such as ophthalmoplegia and ataxia. The difference is that patients with Bickerstaff's brainstem encephalitis have impaired consciousness, whereas patients with Miller Fisher...

Isolated bilateral internal ophthalmoplegia is a rare and problematic condition affecting activities of daily living. Herein, we describe the cases of 2 patients with postinfectious isolated bilateral internal ophthalmoplegia, i.e., mydriasis without external ophthalmoplegia. One patient demonstrated no other neurological symptom, while the other patient showed mild gait ataxia. Magnetic resona...
