Abstract
- Purpose
We report the estimated incidence of, and risk factors for, recurrent anterior uveitis in patients with initial acute-onset Vogt-Koyanagi-Harada (VKH) disease using survival analyses.
Methods
Patients who were diagnosed with initial acute-onset VKH disease during 2003–2022 at two university hospitals were included. Recurrent anterior uveitis was defined as the first occurrence of the granulomatous anterior uveitis with anterior chamber cells and flare of 2+ or more by the Standardization of Uveitis Nomenclature (SUN) Working Group grading scheme, after the disappearance of conspicuous uveitis and serous retinal detachment for at least 3 months, regardless of systemic or local treatment. The univariate log-rank test and multivariate Cox regression analyses were performed, including patients’ demographic characteristics, underlying diseases, presence of prodromal symptoms, duration of visual symptoms, visual acuity, slit-lamp and fundus findings, and height of serous retinal detachment. The treatment method and response to treatment were also included.
Results
The estimated incidence was 39.3% at 10 years. Fifteen of 55 patients (27.3%) had recurrent anterior uveitis during the mean follow-up of 4.5 years. The presence of focal posterior synechiae at the diagnosis increased the risk of recurrent anterior uveitis 6.97-fold compared to the absence of synechiae (95% confidence interval [CI], 2.20–22.11; p < 0.001). Use of systemic high-dose steroid therapy more than 7 days after the development of visual symptoms resulted in a hazard ratio of 4.55 (95% CI, 1.27–16.40; p = 0.020).
Conclusions
This study reports the estimated incidence and risk factors of recurrent anterior uveitis in VKH disease from survival analyses. However, because of the retrospective nature of this study, it is hard to confirm the consistency of the medical records regarding risk factors, thus, the presence of focal posterior synechiae can be inconclusive as a risk factor. Further studies are warranted.
