Abstract

Purpose: To measure changes in the choroidal vascularity index (CVI) in chronic Vogt-Koyanagi-Harada (VKH) disease during a recurrent anterior uveitis attack.

Methods: Forty VKH patients and 40 normal controls were included in this study. Choroidal images were recorded before and during a recurrent anterior uveitis attack, as well as after appropriate treatment. CVI was measured by the binarization technique using ImageJ software (Bethesda, MD).

Results: The CVI was 0.75 +/- 0.09 in quiescent VKH patients, which was significantly higher compared to healthy controls (0.70 +/- 0.05, p <0.0001). The CVI significantly decreased to 0.72 +/- 0.09 when granulomatous anterior uveitis appeared in these patients. However, it returned to 0.75 +/- 0.08 after uveitis resolved.

Conclusions: A significant decrease of the CVI occurred during recurrent anterior uveitis in chronic VKH. CVI may provide a novel parameter to guide the treatment of VKH disease.
