Abstract
PURPOSE
We explore the choroid vasculature changes of acute Vogt-Koyanagi-Harada (VKH) disease using widefield optical coherence tomography angiography (OCTA).
METHODS
In this retrospective, observational, longitudinal study, 16 patients with acute VKH disease (32 eyes, mean age: 42.19 ±13.66 years) were measured using widefield OCTA.
RESULTS
In this study, we first described the multiple dark foci in choriocapillaris and Sattler's layer in the panoramic montage of the five 12x12mm images in 30 eyes (93.8%) of acute VKH disease. OCTA follow-up in these 30 eyes demonstrated the diminished size and number of these dark foci in choriocapillaris and Sattler's layer after the initiation of treatment.
CONCLUSIONS
Widefield OCTA enables noninvasive identification of characteristics of flow void at the level of superficial choroidal vessels in the acute phase and may be a novel valuable tool for diagnosis and monitoring of disease progression in VKH disease in the future.
