To determine the ability of optical coherence tomography angiography (OCTA) to detect choroidal neovascularization (CNV) in the pseudohypopyon stage of adult-onset foveomacular vitelliform dystrophy. ⋯ Optical coherence tomography angiography may be superior to flourescein angiography in detecting CNV in adult-onset foveomacular vitelliform dystrophy, especially in the pseudohypopyon stage. There are common artifacts that must be considered when analyzing vitelliform lesions with OCTA, including segmentation errors and inability to visualize flow under the vitelliform lesion in the choriocapillaris.
