Abstract :
Purpose: To report two cases of typical multiple evanescent white dot syndrome (MEWDS), in which swept‑source optical coherence
tomography angiography (SS‑OCTA) revealed transient areas of flow deficit at the level of the choriocapillaris.
Methods: The SS‑OCTA images of two female patients with typical MEWDS were analyzed at the onset of the disease and during
follow‑up.
Results: The patients were aged 24 and 25 years, respectively. Previous medical history was unremarkable in both cases. The diagnosis
of MEWDS was made on the basis of typical clinical findings and results of fundus autofluorescence, fluorescein angiography, and optical
coherence tomography. At presentation, SS‑OCTA showed a few small hypointense areas of flow deficit at the level of the choriocapillaris in
both cases. During follow‑up, SS‑OCTA showed complete resolution of choriocapillaris flow voids.
Conclusion: Both our patients with typical acute MEWDS showed SS‑OCTA multifocal small areas of flow reduction at the level of the
choriocapillaris, with full recovery during the follow‑up. This finding supports the hypothesis of transient, primary, or secondary choriocapillaris
hypoperfusion in typical MEWDS.
