Study summary

This will be a hospital-based retrospective multi-center study on epidemiologic and clinical characteristics of optic neuritis among Chinese. The investigation will cover about 29 provinces or municipalities all around China.

Read the detailed description

This national investigation will be conducted to describe the epidemiology and clinical characteristics of optic neuritis in China. All the patients will be divided into 3 groups according to the serum demyelinating antibodies (Aquaporin-4 antibody seropositive group, Myelin oligodendrocyte glycoprotein antibody seropositive group and double seronegative group). The investigator will analyze the differences among the three groups.

Primary outcomes:

  • To dig out the different visual acuity (VA, LogMAR) prognosis among the three groups;

    • To calculate the annual relapse rate (ARR) differences among the three groups (relapse times in all the follow-up time in each group/ follow-up time (years) in all in each group).

Secondary outcomes:

  • Other epidemiological and clinical characteristics of optic neuritis patients will be analyzed among the three groups;

    • Orbital or Brain MRI is required in this study, which could avoid the misdiagnosis. We will collect and analyze these MRI data too (including the optic nerve lesions in T2 weight images and T1 enhanced MRI);

      • Results of optical coherence tomography (OCT) (including peripapillary retinal nerve fiber layer, macular thickness ,and ganglion cell and inner plexiform layer complex) at different time point are also needed in this study. However, OCT is not necessarily required;

        • Visual fields at different time points are also encouraged to provide if they are available.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 20, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
