Testing new diagnostic criteria for sudden vision loss from optic nerve inflammation

This study is testing whether new international diagnostic criteria work well for identifying optic neuritis—a condition where the nerve connecting your eye to your brain becomes inflamed, causing sudden vision loss. Researchers are evaluating these criteria in real patients in China and also studying how antibody blood tests might help confirm the diagnosis, especially when certain types of optic neuritis are more common in your region.

Optic neuritis can be caused by different underlying conditions, some of which need very different treatments. Better diagnostic tools can help doctors identify the exact cause more quickly and accurately, so patients get the right care faster.
