Abstract

Purpose
To compare clinical outcomes of Korean patients with seropositive myelin oligodendrocyte glycoprotein antibody (MOG-IgG)-related optic neuritis (ON) and those with neuromyelitis optica antibody (NMO-IgG)-related ON.
Methods
Medical records were analyzed retrospectively among patients diagnosed with ON from January 2018 to June 2020, who were positive for MOG-IgG or NMO-IgG on serological tests. Clinical manifestations and outcomes were collected and compared between the two groups.
Results
The study included 14 eyes of 10 MOG-IgG positive patients, and 38 eyes of 25 NMO-IgG positive patients. Final visual acuity differed significantly between the two groups (p = 0.002), and the proportion of patients with no light perception was higher in the NMO-ON group (11%) compared with the MOG-ON group (0%). The mean deviation value on visual field tests also showed a significant difference between NMO-ON and MOG-ON groups (-18.98 ± 12.36 dB versus -10.17 ± 10.03 dB, respectively; p = 0.018). The recurrence rate was 42% in the NMO-ON group and 79% in the MOG-ON group (p = 0.020).
Conclusions
The clinical outcomes of NMO-ON and MOG-ON patients differed significantly. MOG-ON patients were more likely to experience a relapse. Patients with NMO-ON were given a poor visual prognosis despite having a lower recurrence rate than those with MOG-ON.
