Role of optical coherence tomography angiography in Vogt-Koyanagi-Harada disease

Vogt-Koyanagi-Harada disease (VKH) is an autoimmune severe multisystem condition characterized by both ocular and systemic findings that should be promptly recognized and treated. Although invasive imaging modalities, namely fluorescein angiography and indocyanine green angiography, are still the gold standard for the diagnosis and follow-up of the ocular findings in VKH, the role of retinal non-invasive imaging including optical coherence tomography angiography (OCTA) is under investigation and is not mentioned in the current diagnostic criteria of VKH. The aim of this manuscript was to report the clinical course and the multimodal retinal imaging of a VKH case and to discuss the role of OCTA in this condition. Our case supports the evidence that OCTA is able to help determine disease activity and progression in VKH. We therefore contend that OCTA should be considered for future developing diagnostic criteria of this condition.
