Systemic lupus erythematosus (SLE) is an autoimmune disease that can have detrimental effects on many different systems in the body, including the central nervous system. Neuropsychiatric SLE (NPSLE) refers to several different neurological and/or behavioral clinical syndromes, and has been reported as having a prevalence rate of approximately 30−40%, while manifestation of myelitis or optic ne...

The diagnosis of optic neuritis and particularly retrobulbar optic neuritis when atypical and not responsive to corticosteroid treatment may need to be revised. This is now especially so in male patients who should be questioned regarding their taking a phosphodiasterase-5 inhibitor in particular Viagra. The case history of such a patient is presented who sustained posterior ischaemic optic neu...

The aim of this paper is to compare diameter of healthy and affected optic nerve determined by ultrasound with brain lesions in acute retrobulbar neuritis in patients with multiple sclerosis. In this prospective study 20 patients with multiple sclerosis and acute retrobulbar neuritis were examined. Optic nerve diameter was measured by ultrasound. Brain lesions were detected by magnetic resonanc...

Multiple sclerosis (MS) is considered to be an autoimmune disease of the central nervous system (CNS) that in many patients first presents clinically as optic neuritis. The relationship of optic neuritis to MS is not well understood. We have generated novel T cell receptor (TCR) transgenic mice specific for myelin oligodendrocyte glycoprotein (MOG). MOG-specific transgenic T cells are not delet...

IMPORTANCE Retrospective studies have demonstrated disparate outcomes following acute optic neuritis in individuals of African descent compared with individuals of white race/ethnicity. However, published analyses of the prospectively collected Optic Neuritis Treatment Trial (ONTT) data identified no association between worse visual outcomes and black race/ethnicity. OBJECTIVES To investigate t...

One hundred and one of 146 patients presenting with isolated idiopathic optic neuritis, previously reviewed in 1978, were reassessed clinically, and retyped for HLA antigens and Factor B alleles, after a mean follow-up of 11.6 years. Fifty eight patients (57%) had developed multiple sclerosis at the time of reassessment in the present study, of whom 51 (88%) had clinically definite disease. Thi...

110 cases of optic neuritis were prospectively studied. 62 (56%) developed multiple sclerosis, 13 were lost to survey. However, eight of these had recurrent episodes of optic neuritis. If recurrent episodes of optic neuritis are accorded the same significance as demyelination elsewhere in the CNS, then the incidence of multiple sclerosis in the series rose to 71%, similar to that predicted on a...

Purpose. To report a case of unilateral optic neuritis following Measles-Mumps-Rubella (MMR) vaccination. Methods. A 30-year-old female developed unilateral optic neuritis five days after a Measles-Mumps-Rubella (MMR) booster vaccination. The patient displayed unilateral involvement, with severe visual loss. However, visual acuity improved significantly after four days of intravenous steroid th...

PURPOSE. To examine the biomechanical deformation of load bearing structures of the optic nerve head (ONH) resulting from raised intracranial pressure, using high definition optical coherence tomography (HD-OCT). The authors postulate that elevated intracranial pressure induces forces in the retrolaminar subarachnoid space that can deform ONH structures, particularly the peripapillary Bruch's m...

Purpose: To study the frequency and characteristics of ocular manifestations in patients with multiple sclerosis (MS) in the state of São Paulo. Methods: From March, 1996 to November, 1998, 64 patients (48 females, 16 males, age 17 59 years) with MS underwent ophthalmologic examination and computerized visual field perimeter testing. Results: Forty-four (68.75%) of the 64 examined patients pres...
