EDI-OCT as an auxiliary examination for the differential diagnosis of bullous CSC and Vogt-Koyanagi-Harada: A case report.

ABSTRACT

A 46-year-old male patient visited our clinic with a complaint of blurred vision in the right eye accompanied by headache and insomnia. The fundus examination showed three bullous retinal detachments in the right eye. Considering the prodromal symptoms and other fundus characteristics such as vitreous cells in the posterior pole and multifocal fluorescence leakages on fundus fluorescein angiography (FFA), initial diagnosis was considered as Vogt-Koyanagi-Harada (VKH). However, oral glucocorticoids didn't improve patient's vision. Further enhanced depth imaging (EDI)-optical coherence tomography (OCT) scan displayed hyper-reflective lesions at the choroidal layer. We proposed that hyper-reflective lesions at the choroidal layer on EDI-OCT may characterize the bullous variant of central serous chorioretinopathy (CSC). After fundus photocoagulation treatment, the patient's vision improved.
