Chronic Recurrent Vogt–Koyanagi–Harada Disease and Development of ‘Sunset Glow Fundus’ Predict Worse Retinal Sensitivity

This is the authors' abstract. We don't add key points for this paper.

PURPOSE: To investigate prognostic factors for retinal sensitivity assessed by microperimetry in patients with Vogt-Koyanagi-Harada (VKH) disease. METHODS: In total, 34 patients with initial-onset acute disease and 19 patients with chronic recurrent disease were retrospectively evaluated. RESULTS: The mean follow-up period was 40.4 ± 40.5 months. Sensitivity was significantly worse in eyes with more severe anterior segment inflammation at presentation, as indicated by the presence of mutton-fat keratic precipitates, anterior chamber reaction ≥2+, and posterior synechiae. Chronic recurrent presentation, development of complications, and 'sunset glow fundus' were significantly associated with worse sensitivity. Using logistic regression analysis, better sensitivity was significantly associated with initial-onset acute presentation (odds ratio, OR = 6.9; 95% confidence interval, CI = 1.53-9.66). CONCLUSIONS: Chronic recurrent presentation and development of complications and 'sunset glow fundus' are associated with a worse sensitivity outcome.
