Giant cell arteritis with ocular involvement is an ocular emergency. Arteritic anterior ischaemic optic neuropathy (AAION) is the most common ophthalmological manifestation associated with this disease. Visual loss is usually permanent with rare cases showing visual recovery. Visual improvement, if it occurs, is generally limited, and the visual field defects are persistent and severe. The main goal of AAION treatment is the preservation of vision in the fellow eye. In patients with neurophthalmological manifestations, high-dose corticosteroids should be initiated immediately and aggressively, and maintained thereafter...

Cerebral visual impairment is a visual function deficit caused by damage to the retrogeniculate visual pathways in the absence of any major ocular disease. It is the main visual deficit in children in the developed world. Preperinatal hypoxic-ischemic damage is the most frequent cause of cerebral visual impairment, but the etiology is variable. The authors set out to evaluate the presence of visual disorders not attributable to any major ocular pathology in a sample of children with central nervous system disease and to describe the clinical picture of cerebral visual impairment in this cohort...

OBJECTIVE: Paraneoplastic neurologic syndrome with otoneurophthalmologic manifestations is much less common than direct, metastatic, and treatment-related complications of cancer. Few studies have focused on patients presenting with paraneoplastic syndrome before a cancer is identified. PATIENT: We describe a case of combined paraneoplastic brainstem/limbic encephalitis and Lambert-Eaton myasthenic syndrome in a patient with small cell lung cancer and positive antiamphiphysin antibodies who initially presented with otoneurophthalmologic signs and symptoms to the ears, nose, and throat clinic...

OBJECTIVE: To determine the causative factors and epidemiology of bilateral vestibulopathy (BV). METHODS: This is a retrospective review of 255 patients (mean age, 62 +/- 16 years) with BV diagnosed in our dizziness unit between 1988 and 2005. All patients had undergone a standardized neurophthalmological and neurootological examination, electronystagmography with caloric irrigation, cranial magnetic resonance imaging or computed tomography (n = 214), and laboratory tests...

Sensory deficits have been documented in Parkinson's disease, in particular within the visual domain. However, ageing factors related to the brain and to neural and non-neural ocular structures could explain some of the previously reported results, in particular the claimed impairment within the koniocellular pathway. This study addressed visual impairment attributable to the magno- (luminance), parvo- (red-green) and koniocellular (blue-yellow) pathways in a population of Parkinson's disease patients. To avoid potentially confounding factors, all subjects underwent a full neurophthalmological assessment which led to exclusion of subjects with increased intraocular pressure, diabetes even in the absence of retinopathy, and ocular abnormalities (from a total of 72 patients' eyes, 12 were excluded)...

Leber congenital amaurosis (LCA) is the most severe form of inherited retinal dystrophy that presents in infancy. LCA is both clinically and genetically heterogeneous. The aim of our study was to clarify the clinical aspects of LCA and to contribute to improved characterization of the disorder. We studied 40 children affected by LCA (mean age at first observation: 19 months, range: 8-50 months), who underwent a comprehensive evaluation that included: neurophthalmological evaluation, electroretinogram (ERG), and visual evoked potentials (VEPs), general and neurological examinations, developmental assessment using scales for visually impaired children, neuroradiological examinations, hepatic and renal function and metabolic investigations, brainstem auditory evoked potentials (BAEPs), EEG, and hand radiographs...

We set out to define visuo-perceptual impairment related to periventricular leukomalacia (PVL) using the Developmental Test of Visual Perception (DTVP). Correlations were sought between visual-perceptual deficits and DTVP profile and neuroradiological and neurophthalmological findings. The DTVP was administered to 20 children (m/f: 10/10), aged between 5 and 8 years (mean: 6.95 years), presenting with: spastic diplegia; PVL documented by brain MRI; normal or mildly impaired visual acuity; mild-moderate upper limb functional impairment...

REVIEW

OBJECTIVE: This report describes two shunted patients evaluated with continuous intracranial pressure (ICP) monitors for worsening headaches and subsequently diagnosed with obstructive sleep apnea. CLINICAL PRESENTATION AND INTERVENTION: ICPs were monitored with strain-gauge sensors inserted into the frontal cortex. After the initial diagnosis of sleep apnea, 8-hour attended polysomnography was performed in each patient. Both patients showed apnea-hypopnea indices greater than 15...

MULTICENTER STUDY
B Girard, F Bourcier, I Agdabede, L Laroche
PURPOSE: To investigate the numbers and characteristics of patients with ophthalmological emergencies presenting at a general hospital. METHODS: Retrospective analysis of ophthalmological emergencies over 11 years included comparison with demographic changes and, over the last 2 years, analysis of the patients treated (age, sex, and pathology, according to 23 preselected pathologies). Ophthalmological examinations were done by a senior ophthalmologist. RESULTS: The activity rose from 396 patients in 1989 to 2,793 in 2000...

OBJECTIVE: Resection of benign cavernous sinus tumors with minimum morbidity and mortality is increasingly more common. Although meningiomas have dominated most discussions, numerous nonmeningeal tumors also deserve attention because they are generally more amenable to radical surgical resection. METHODS: We reviewed the records of 40 patients (19 female and 21 male patients) who were treated surgically during a 15-year period for benign, nonmeningeal tumors of the cavernous sinus...

COMPARATIVE STUDY
A Alcalá, O Fernández, C Juárez
With the aim of defining the neuro-ophthalmological alterations in multiple sclerosis, both with respect to visual and oculomotor aspects, we have studied a sample of 100 clinically definite multiple sclerosis patients, all in the remittent phase of the disease. We compared them with a sample of 100 unrelated healthy controls, matched for age and sex. Visuomotor alterations were found in 99%, purely visual alterations in 38%, purely oculomotor alterations in 3%, and mixed alterations in 58% of the MS patients...

PURPOSE: To determine whether the "gatekeeper physician system" for evaluating neuro-ophthalmologic problems is cost effective. METHODS: The authors retrospectively reviewed the records of 588 patients referred for neuro-ophthalmologic evaluation between July and December 1989 to determine the frequency and cost of unnecessary diagnostic testing ordered by "gatekeeper physicians." Pre-referral diagnostic testing costs were compared with the cost of neurophthalmologic consultation for four common problems: (1) optic neuropathy; (2) diplopia; (3) ptosis; and (4) proptosis...

Visual and oculomotor changes may be the only abnormalities in patients complaining of headache. Ocular signs are common during episodes of migraine and cluster headache. Temporal arteritis may be an extracranial cause of ocular signs. Intracranial disorders include painful ophthalmoplegia, pseudotumor cerebri and various causes of increased intracranial pressure. Neurophthalmologic evaluation in headache patients must include assessment of visual acuity and visual fields, examination of pupils (including pharmacologic testing), ophthalmoscopic examination and auscultation for bruits...

R G Curless
Acute, vestibular symptoms in childhood are primarily caused by acute labyrinthitis (end organ dysfunction) or central nervous system diseases such as neoplasia involving the pons or cerebellar nuclei or infection manifested by pontine encephalitis. The evaluation, treatment, and prognosis of end organ versus central disease is so different that the ability to make a bedside, presumptive diagnosis provides an important advance. Both patients presented here had a central vestibulopathy. By paying particular attention to the character of the nystagmus and past pointing, the Romberg test, and the details of the vertiginous history, central disease was the presumptive diagnosis prior to invasive procedures...
