BACKGROUND Neuromyelitis optica (NMO) is an inflammatory disease with combined features of optic neuritis and myelitis. This pathologic entity may induce severe disability, including visual loss and paraplegia. Other than clinical follow-up, there is no marker for severity of the disease. OBJECTIVES To evaluate the use of optical coherence tomography(More)
The impact of climate on the vector behaviour of the worldwide dog tick Rhipicephalus sanguineus is a cause of concern. This tick is a vector for life-threatening organisms including Rickettsia rickettsii, the agent of Rocky Mountain spotted fever, R. conorii, the agent of Mediterranean spotted fever, and the ubiquitous emerging pathogen R. massiliae.

INTRODUCTION Multiple sclerosis is a common disabling progressive neurological disorder. Axonal loss is thought to be a likely cause of persistent disability after a multiple sclerosis relapse. Retinal nerve fiber layer (RNFL) imaging by optical coherence tomography (OCT) seems to be a non-invasive way of detecting optical axonal loss following optic(More)
INTRODUCTION Mild ophthalmoparesis can be seen in oculopharyngeal muscular dystrophy (OPMD). METHODS Orthoptic analysis included assessment of phoria/tropia, eye excursion, saccades, pursuit, stereoacuity, and Hess-Lancaster screen test. Video-oculography included fixation, horizontal and vertical saccades, and pursuit. RESULTS Orthoptic abnormalities(More)
Functional or non-organic visual loss is a common problem in neuro-ophthalmologic consultation. There is a mismatch between visual acuity and/or visual field and the relative normality of the clinical examination. It is important to identify these patients so as not to prescribe unnecessary ancillary testing and so as to refer patients for a treatment of a(More)
A 72-year-old patient presented with a left-sided Wal-lenberg syndrome, including thermoalgic anesthesia associated with severe itching leading to ulcerations in the left trigeminal area (Fig. 1). Few cases of so-called ''neurotrophic'' ulcerations in the trigeminal area (sometimes with corneal involvement) following lateral med-ullary infarction have been(More)
