Autoantibodies have defined two paraneoplastic visual disorders related to small-cell lung carcinoma: retinopathy ("CAR"-IgG [23kDa, recoverin]) and optic neuritis collapsin response-mediated protein 5 (CRMP-5-IgG [62kDa]). Among 16 patients with CRMP-5-IgG and optic neuritis (aged 52-74 years; all smokers, 9 women), we documented coexisting retinitis in 5.(More)
BACKGROUND Since they were first derived more than three decades ago, embryonic stem cells have been proposed as a source of replacement cells in regenerative medicine, but their plasticity and unlimited capacity for self-renewal raises concerns about their safety, including tumour formation ability, potential immune rejection, and the risk of(More)
PURPOSE To assess the allelic variation of the ATP-binding transporter protein (ABCA4). METHODS A combination of single-strand conformation polymorphism (SSCP) and automated DNA sequencing was used to systematically screen this gene for sequence variations in 374 unrelated probands with a clinical diagnosis of Stargardt disease, 182 patients with(More)
Increasingly, mutations in genes causing Mendelian disease will be supported by individual and small families only; however, exome sequencing studies have thus far focused on syndromic phenotypes characterized by low locus heterogeneity. In contrast, retinitis pigmentosa (RP) is caused by >50 known genes, which still explain only half of the clinical cases.(More)
An otherwise healthy 6-week-old girl who presented with an isolated left third cranial nerve palsy underwent MRI that revealed an enhancing mass intrinsic to the left third cranial nerve. Rapid enlargement of the lesion over 1 month led to subtotal neurosurgical resection of an atypical teratoid/rhabdoid tumor (AT/RT), a rare, highly aggressive malignancy(More)
OBJECTIVE To determine the frequency of the association between tonic spasms and neuromyelitis optica (NMO) at our center. DESIGN An institutional review board-approved retrospective study of clinical, serological, and radiographic characteristics of patients with NMO. SETTING Multiple sclerosis center. PATIENTS Patients with NMO treated at our center(More)
We report three patients with chronic headaches and optic neuropathy due to widespread meningeal thickening shown on enhanced MRI; all had biopsy-proven intracranial pachymeningitis (fibrosclerosis of the meninges). Two patients had bilateral optic neuropathy, elevated CSF protein, and polyclonal serum hypergammaglobulinemia. They developed temporal lobe(More)
PURPOSE The diagnoses of both anterior ischemic optic neuropathy (AION) and optic neuritis are clinical ones with significant overlap of symptoms and signs. This study investigates the presence and character of pain at the onset of AION, in order to evaluate this symptom as a differentiating diagnostic feature between optic neuritis and AION. METHODS(More)
PURPOSE Because palpebral fissure asymmetry in horizontal gaze is reportedly common in otherwise normal persons, we determined the prevalence of physiologic palpebral fissure asymmetry for primary and horizontal gazes. METHODS We measured the palpebral fissure height of both eyes of 88 healthy white subjects. Measurements were obtained with(More)
