Long-term recurrence interval of Vogt–Koyanagi–Harada disease post-COVID-19 vaccination: A case study

Abstract

Purpose This study aimed to report a case of Vogt–Koyanagi–Harada (VKH) disease that recurred 46 years after initial treatment; the recurrence occurred 2 months after the third dose of coronavirus disease 2019 vaccination.Case report: A 59-year-old female patient had bilateral blurring for 2 months; she received her third dose of coronavirus disease 2019 vaccine 4 months before the onset of blurring. The best-corrected visual acuity was 1.0 in the right eye and 0.15 he left eye at the initial visit. Iritis and synechia between lens and iris were observed bilaterally. Sunset glow fundus was found in both eyes with no serous retinal detachments or disk hyperemia. She had a history of VKH disease and was treated with whole-body corticosteroid administration at another hospital when she was 13 years old. She was diagnosed with VKH disease recurrence, and oral corticosteroid intake and corticosteroid eyedrop treatments were initiated. The treatment response was good, but left synechia remained between the lens and iris in the left eye. Recurrence was not observed for 10 months until this study, and her best-corrected visual acuity was 1.0 in both eyes.Conclusion To our knowledge, this case represents the longest recorded interval of VKH disease recurrence in the literature.
