VKH Syndrome
Conditions
Keywords
VKH; immune profile;
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.
Interventions
IV and oral steroids

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| T/B /NK(natural killer )/monocyte...etc, cell numbers of blood samples in VKH patients | one year | 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 | one year | use flow cytometry to measure T/B /NK/monocyte...etc cell subtype proportion |
| T/B /NK/monocyte...etc cell functional change in VKH patients | one year | use ELISA(enzyme linked immunosorbent assay) to measure inflammatory cytokines level in peripheral blood |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| choroid and retinal thickness change in different course of VKH patients | one year | Use OCT(optical coherence tomography) to measure choroid and retina thickness changes in macular zone of different course VKH patients |
| measure the Injury degree of choroid and retinal vessels | one year | Use FFA(fluorescein fundus angiography)/ICG(Indocyanine Green Angiography) to measure the Injury degree of choroid and retinal vessels |
| Use OCTA(optical coherence tomography angiography) to measure macular and optic disc vascular index | one year | Use OCTA to measure macular and optic disc vascular index in different course VKH patients |
| Use Maia perimeter to measure macular integrality | one year | Use Maia perimeter to measure macular integrality including light threshold and central fixation. |
