To report the case of a patient who presented with idiopathic choroidal neovascularization (CNV) as the first sign of multiple evanescent white dot syndrome (MEWDS). A 25-year-old woman presented with recent onset of decreased vision and metamorphopsia in the right eye. The results of fundoscopic examination, fluorescein angiography, and optical coherence tomography (OCT) were compatible with a diagnosis of idiopathic CNV, which was treated with one intravitreal injection of bevacizumab. Five years later, the patient returned complaining of photopsia and decreased vision in the same eye. The fundoscopic examination showed typical signs of MEWDS. After 3 months, recurrence of CNV was observed in the same eye. In conclusion, idiopathic CNV might be the only manifestation of a subclinical occurrence of MEWDS. In this case, it was followed by a recurrence of MEWDS and subsequent reactivation of CNV.
