The aim of this study was to compare retinal nerve fiber layer thickness (RNFLT) between spectral-domain (SD-) and time-domain optical coherence tomography (TD-OCT) in MS patients and healthy controls (HC). Furthermore, RNFLT between MS eyes with and without optic neuritis (ON) and HC should be explored. Finally, the relationship between RNFLT, disease duration, EDSS, and disease modifying therapy (DMT) should be established.<jats:italic>Design<\/jats:italic>. Prospective, cross-sectional study.<jats:italic>Participants<\/jats:italic>. 28 MS patients and 35 HC.<jats:italic>Methods<\/jats:italic>. Both groups underwent TD- and SD-OCT measurements. RFNLT was correlated between the two machines and between MS eyes with and without ON and HC. Furthermore, RNFLT was correlated to disease duration, EDSS and DMT.<jats:italic>Results<\/jats:italic>.
