Multimodal Imaging of Annular Choroidal Detachment in a Patient with Vogt–Koyanagi–Harada Disease

ABSTRACT

Purpose: To report a rare case of Vogt-Koyanagi-Harada (VKH) patient with bilateral annular choroidal detachment and describe ultra-widefield angiographic findings.

Method: Case report.

Results: A 61-year-old male was diagnosed as VKH based on ocular signs and neurologic findings. Annular choroidal detachment anterior to the equator was noted in both eyes. Ultra-wide field (UWF) fluorescein angiography revealed multiple leakages at posterior pole and disc with dye pooling at the margin of choroidal detachment. Late-phase UWF indocyanine green angiography (ICGA) revealed hyperpermeability with dilated veins and many vortex ampullae obscured by detached choroid. Choroidal detachment and other manifestations improved after a high-dose systemic steroid treatment. UWF ICGA after the treatment revealed decreased choroidal vessel caliber with visible vortex ampullae.

Conclusion: Vortex obstruction and choroidal vein dilatation were observed in a VKH patient with choroidal detachment, which might be related to its pathophysiology.
