Approval of the study was obtained from the hospital's ethical committee. The study design and methodology followed the tenets of Declaration of Helsinki. All patients were provided with written informed consent and received a thorough explanation of the use of Mycophenolate Mofetil, its potential risks and benefits. This is a monocenter, cohort, observational study evaluating patients with relapse VKH divided into two groups: Mycophenolate Mofetil therapy group and traditional therapy group.~For Mycophenolate Mofetil therapy group, an initial dose of 0.5-1.0g bid MMF was orally administered every day, glucocorticoid was started at a dose of 0.5-0.8 mg/kg/day and no more than 60 mg/day. For the traditional therapy group, patients were treated with glucocorticoids alone or glucocorticoids combined with Cyclosporine. Study participants will be followed for up to one year to determine efficacy and side effects.~According to best corrected visual acuity (BCVA), anterior chamber and vitreous inflammation, optical coherence tomography (OCT), change in corticosteroid dose during the study period and so on. The investigators evaluate the anti-inflammatory and immunosuppressive effects of MMF in treatment of relapse VKH.
This project is designed to test the hypothesis that Mycophenolate Mofetil is clinically useful for patients with relapse Vogt-Koyanagi-Harada disease
