Abstract

Uveitis is a complex disease with many complications that threaten vision. Among them, Vogt-Koyanagi-Harada syndrome is a fairly common autoimmune uveitis. The diagnostic criteria for VKH syndrome are mainly based on clinical features, however, paraclinical tests also play an important role in guiding diagnosis and prognosis. OCT not only helps to assess subretinal fluid, retinal detachment, and retinal pigment epithelium folds but also helps to assess below the retinal pigment epithelium such as measuring the choroidal thickness. The choroidal thickness at different stages in VKH patients varies. The choroid thickens in the acute stage and thins in the chronic stage. Assessing the choroidal thickness in VKH patients helps in accurate diagnosis as well as monitoring the course, treatment, and prognosis of recurrence.
