The aim of this study is to evaluate the efficacy and safety of corticosteroidcombining noncorticosteroid systemic immunomodulatory therapy (NCSIT) for the treatment of Vogt Koyanagi Harada disease (VKH).

Vogt Koyanagi Harada disease (VKH) is a sort of autoimmune disease directed against uveal melanocytes, which is a common vision-threatening noninfectious uveitis in colored people. VKH patients given prednisone monotherapy are prone to relapse.

Noncorticosteroid systemic immunomodulatory therapy (NCSIT) demonstrated inflammation control and steroid-sparing effect in autoimmune diseases. Methotrexate as an antifolate metabolite has been widely used for its anti-inflammatory and immunomodulating properties. Adalimumab, humanized monoclonal anti-TNF-α antibody, have demonstrated the efficacy of noninfectious uveitis. Several randomized controlled trials have proved the efficacy and safety of NCSIT such as antimetabolite and biologics in non-infectious uveitis, while the optimal dose and treatment course remain unknown.

The investigators propose to explore the effect, safety and optimal dose of prednisone combining NCSIT in the treatment of VKH.

Inclusion Criteria:

• Diagnosis is based on Revised International Diagnostic Criteria (Read et al. 2001b).
• Age from 12 to 70 years old.
• Patients have no contraindication of prednisone and immunosuppressive therapy, as determined by the investigator based on the results of laboratory and physical examinations.
• Written informed consent is provided.

Exclusion Criteria:

• Patients with other ocular diseases or fundus diseases: diabetic retinopathy, neovascular/wet age-related macular degeneration
• History of renal or hepatic insufficiency, heart failure, systemic inflammatory disease or any other condition that, in the opinion of the investigator, would put the patients at risk by participating in the protocol.
• History of infectious disease like chronic or active hepatitis B infection, HIV infection, immunodeficiency syndrome, chronic recurring infections, or active tuberculosis.
• Female patients who were pregnant or considering becoming pregnant during the study.

VKH patients treated at Zhongshan Ophthalmic Center between October 2021 and October 2025.

The aim of this study is to evaluate the efficacy and safety of prednisone combining noncorticosteroid systemic immunomodulatory therapy (NCSIT) for the treatment of Vogt Koyanagi Harada disease (VKH).
