Summary
This will be a hospital-based retrospective multi-center study on epidemiologic and clinical
characteristics of
Description
This national investigation will be conducted to describe the epidemiology and clinical
characteristics of
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 theoptic nerve lesions in T2 weight images and T1 enhanced MRI); - Results of
optical coherence tomography (OCT) (including peripapillaryretinal nerve fiber layer, macular thickness ,andganglion 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.
