NCT04025476

Brief Summary

The investigators will collect blood samples of different courses of VKH patients for investigating immune profile, observe major immune cells number ,functional and membrane molecular changes in the course of treatment, to investigate pathogenesis of VKH. Meanwhile, the investigators will collect clinical data of VKH patients to observe choroid and retina change in different courses.

Outcome Measures

Primary Outcomes (3)

  • T/B /NK(natural killer )/monocyte...etc, cell numbers of blood samples in VKH patients

    use flow cytometry to count T/B /NK/monocyte...etc, cell numbers

  • T/B /NK/monocyte...etc cell subtype proportion in blood samples in VKH patients

    use flow cytometry to measure T/B /NK/monocyte...etc cell subtype proportion

    one year

  • T/B /NK/monocyte...etc cell functional change in VKH patients

    use ELISA(enzyme linked immunosorbent assay) to measure inflammatory cytokines level in peripheral blood

    one year
