PURPOSE To measure the thickness of retinal peripapillary nerve fibers throughout the course of neuromyelitis optica (NMO). METHODS This study was of a cross-sectional design, examining the thickness of the retinal peripapillary nerve fiber layer by optical coherence tomography, in patients with NMO (n = 15; 30 eyes), patients with multiple sclerosis (MS;(More)
To study the correlation between the results of frequency-doubling technology perimetry (FDTP), visual function (visual acuity, contrast vision, standard automated perimetry (SAP)) and the thickness of the retinal nerve fiber layer (RNFL) throughout the course of multiple sclerosis (MS). Sixty-six eyes of thirty-three patients suffering from MS were chosen.(More)
PURPOSE Optic neuritis (ON) observed during neuromyelitis optica (NMO) is in most cases very severe and with poor prognosis. This study's objective was to analyze visual field (VF) abnormalities observed in the absence of ON and post-ON episode. METHODS Twenty-seven cases of both NMO and multiple sclerosis (MS) were selected. Thorough ophthalmologic exam(More)
