Purpose:
To compare the visual evoked potentials (VEPs) of optic neuritis (ON) patients with multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and controls. To evaluate correlations between VEP and optical coherence tomography (OCT), contrast sensitivity (CS), and automated perimetry.
Methods:
Fifty-five eyes with ON from...
Purpose: To evaluate the intermediate and outer retina of patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) using OCT and multifocal electroretinography (mf-ERG).
Methods: Patients with MS (n = 30), NMOSD (n = 30), and healthy controls (n = 29) underwent visual field (VF), OCT, and mf-ERG testing. The eyes wer...

... Saidha et al. (2011), in line with our finding, demonstrated abnormal distal retinal responses, i.e., reduced mfERG-P1 peak time in NON, but found, in contrast to our and others' findings (Hanson et al., 2018;Al-Nosairy et al., 2021b), a thinned distal retina. In contrast to the present study, others have also demonstrated abnormal distal retinal layer responses in HON, i.e., reduced mfERG-N1 and -P1 peak times (Filgueiras et al., 2019) or delayed mfERG-P1 peaks (Hanson et al., 2018). Whether the reduced peak times of the distal retina are due to hyperexcitable inflammatory neurons or due to loss of specific cell components generating the responses (Ikeda et al., 1989;Hood et al., 2002;Filgueiras et al., 2019) is still unresolved. ...
