Abstract Purpose:In Vogt-Koyanagi-Harada disease(VKHD), the choroid thickens rapidly during the active phase. In this study, we investigated the relationship between subfoveal choroidal thickness(SCT) measured using optical coherence tomography during treatment of VKHD and symptomatic relapse.

Subjects and methods:Patients with newly diagnosed VKHD who first visited SHOWA Medical University East Hospital between May 2019 and May 2023 were included, and were classified into a relapse group and a non-relapse group based on the presence or absence of symptomatic relapse. SCT values before the start of treatment, and 1 week, 2 weeks, 1 month, 3 months, 6 months, and 12 months after treatment were retrospectively examined in both groups.

Results:The mean SCT before the start of treatment was 848±132 μm in the relapse group and 680±234 μm in the non-relapse group, which was significantly higher in the relapse group(p<0.01). Logistic regression analysis was performed using the presence or absence of symptomatic relapse according to the SCT value before the start of treatment as the dependent variable, and the risk of symptomatic relapse was significantly higher with a higher SCT before the start of treatment(β=0.00567, p=0.008, odds ratio=1.0051, 95% CI:1.0013-1.0089).

Conclusion:It was suggested that patients with a thicker SCT before the start of treatment may have a higher risk of symptomatic relapse, but it was difficult to exclude various factors that affect choroidal thickness.
