Posterior cortical atrophy is a striking clinical syndrome in which a dementing illness begins with visual symptoms. Initially, the problem may seem to be loss of elementary vision, but over time the patient develops features of visual agnosia, topographical difficulty, optic ataxia, simultanagnosia, ocular apraxia (Balint's syndrome), alexia, acalculia,(More)
BACKGROUND Selective amygdalohippocampectomy (SelAH) is increasingly performed in patients with mesial temporal lobe epilepsy and hippocampal sclerosis. To determine whether visual field defects are less pronounced after SelAH than after standard temporal lobectomy (StTL), we retrospectively analyzed postoperative quantitative visual fields after the 2(More)
Conditions associated with nausea and vomiting, such as motion sickness or side effects of medications, are commonly associated with a clinical picture consistent with parasympathetic activation and sympathetic withdrawal. It can be postulated, therefore, that vestibular stimulation contributes to sympathetic withdrawal. To test this hypothesis five normal(More)
Four patients each developed a reversible homonymous hemianopia caused by non-ketotic hyperglycemia. In two patients the homonymous hemianopia was the first manifestation of diabetes mellitus type 2. All four patients had abnormal MRI scans; in the three patients who had late follow-up scans the abnormalities resolved completely. In one patient the(More)
OBJECTIVE To describe the incidence and characteristics of acute and rapidly progressive visual loss in idiopathic intracranial hypertension (IIH). METHODS We reviewed the medical records of all patients with IIH seen at two institutions. "Fulminant IIH" was defined as the acute onset of symptoms and signs of intracranial hypertension (less than 4 weeks(More)
OBJECTIVE To evaluate and quantify prospectively visual field changes in patients undergoing temporal lobe resections for intractable epilepsy. BACKGROUND Visual field abnormalities occur after temporal lobe resections for epilepsy; however, we have not encountered published reports using automated static visual field analysis. METHODS Humphrey visual(More)
BACKGROUND The tonic ocular tilt reaction (OTR) consists of vertical divergence of the eyes (skew deviation), bilateral conjugate ocular torsion, and paradoxical head tilt. The head and superior pole of both eyes are rotated toward the hypotropic eye. OBJECTIVE To describe ocular motility and torsion findings in 5 patients with OTRs that mimicked superior(More)

The Arnold-Chiari malfomation is typically associated with downbeat nystagmus. Eye movement recordings in two patients with Arnold-Chiari malfomation type 1 showed, in addition to downbeat and gaze evoked nystagmus, intermittent nystagmus of skew. To date this finding has not been reported in association with Arnold-Chiari malfomation. Nystagmus of skew(More)
PURPOSE The one-and-a-half syndrome is an eye movement disorder characterized by a unilateral gaze palsy and an ipsilateral internuclear ophthalmoplegia. The authors describe a previously unrecognized association between the one-and-a-half syndrome and oculopalatal myoclonus (OPM). METHODS Five clinical cases are presented, with pertinent physical(More)
