Neurological outcome and predictive factors of idiopathic optic neuritis in China

The combined conversion rate for ION to MS/NMO in Chinese population was lower than the reported rate for Western countries. In addition to some previously reported high risk factors, white matter lesions on the brain MRI at baseline and good visual recovery were found to be good predictors for Chinese ION converting into MS whereas poor visual recovery with a normal brain MRI suggested a higher likelihood of the ION converting into NMOSD.
