Delayed-onset unilateral Vogt-Koyanagi-Harada syndrome: a multimodal imaging appraisal

A 38-year-old woman who had previously been diagnosed and treated for unilateral Vogt-Koyanagi-Harada syndrome (VKH) and had undergone multiple intravitreal bevacizumab injections to manage inflammatory choroidal neovascularisation in her right eye, presented 2 years later with visual complains in left eye. Clinical examination, fluorescein angiography, indocyanine green angiography (ICGA) and enhanced depth imaging optical coherence tomography (EDI-OCT) assisted evaluation confirmed active inflammation of left eye along with absence of any inflammation in the right eye. Unilateral active inflammation can be seen in the setting of VKH. To our best knowledge, ours is the first case of VKH in which unilateral active inflammation has been proven based on ICGA and EDI OCT analysis.
