A 44-year-old female patient reported a "black dot" which had been in front of the right eye for more than 4 days and which moved together with eye movements. The optical coherence tomography (OCT) image of the right macula showed large cystic cavities and thickening within the retinal pigment epithelium (RPE) near the fovea centralis as well as small bore cystic alterations, which indicated an event in the region of the choroid. Fluorescein angiography and indocyanine green angiography excluded choroidal neovascularization (CNV). The diagnosis revealed a broad superficial choroidal blood vessel mimicking a subretinal hemorrhage.
