BackgroundThe clinical characteristics of pediatric optic neuritis (ON) patients with seropositive myelin oligodendrocyte glycoprotein (MOG) antibodies in Asian have not been reported.Main proceduresAcute onset ON patients ≤ 18-years-old were enrolled.Serum MOG and aquaporin-4 (AQP4) antibodies were detected and patients were followed-up for at least 6 months. The demographic, clinical and radiological features, together with optical coherence tomography (OCT) were evaluated among MOG-seropositive ON (MOG-ON), AQP4-seropositive ON (AQP4-ON) and double seronegative ON (seronegative-ON). Best corrected visual acuity (BCVA), thickness of optic disc retinal nerve fiber layer (RNFL) and macular ganglion cell complex (GCC) measured by OCT at 6 months after an acute attack. The clinical features in MOG seropositive pediatric ON were compared with other phenotypes.Main findingsAmong MOG-ON (n=10, eyes=19), AQP4-ON (n=9, eyes=15) and seronegative-ON (n=40, eyes=62), the percentages of BCVA measured better than 0.8 (20/25) at the 6-month visit were 89.47%, 33.33% and 82.26% respectively, which were significantly better in MOG-ON and seronegative-ON patients than that of AQP4-ON patients (p=0.02). The average peripapillary RNFL were 58.03±8.73µm, 64.34±12.88µm and 78.12±13.34µm for the MOG-ON, AQP4-ON and seronegative-ON patients respectively, which showed no statistic difference between MOG-ON and AQP4-ON patients (p=0.089), but were both thinner than seronegative-ON patients (p=0.001).ConclusionsThe recovery of visual acuity in MOG-ON patients was as good as in seronegative-ON patients, and the RNFL of the optic nerve head showed thinning as severe as the AQP4-ON patients.
