Value of OCT Angiography in the Diagnosis of Choroidal Neovascularization Complicating Multiple Evanescence White Dot Syndrome.

This report describes a 19-year-old patient with the rare association of multiple evanescent white dot syndrome (MEWDS) and choroidal neovascularization (CNV). Despite the initial diagnosis of MEWDS, her vision significantly decreased. Fluorescein angiography showed dye leakage and pooling at the macula, whereas optical coherence tomography (OCT) showed cystoid macular edema and serous neuroepithelial elevation. The dye leakage and pooling made it impossible to diagnose CNV. However, OCT angiography (OCTA) revealed a vascular structure in the outer retina, thereby leading to the CNV diagnosis. Visual acuity improved after an anti-vascular endothelial growth factor injection. OCTA proved to be useful in the diagnosis of CNV. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:580-584.].
