ABSTRACT
Purpose
To evaluate multifocal evanescent white dot syndrome (MEWDS) patients with and without overlapping multifocal choroiditis (MFC).
Methods
Thirty-four patients diagnosed between November 2008 and August 2018 at 2 hospitals were retrospectively reviewed. Multimodal imaging including optical coherence tomography angiography (OCTA) was assessed.
Results
Twenty-seven (79%) patients were women (overall mean age, 30 years). Five developed MFC lesions in the affected eyes, and one developed MFC in the unaffected fellow eye. Another developed combined MEWDS and MFC in the fellow eye during follow-up. Eyes with MFC had thicker choroids (316.5 and 197.3 µm, respectively; P = .001) at presentation, which became thinner after resolution (P = .043). Those with subfoveal MFC had poor visual prognosis (P = .019). Areas of suspected choriocapillaris flow deficit were identified on OCTA.
Conclusion
Some MEWDS patients may develop overlapping MFC in the same or fellow eyes, presenting with increased choroidal thickness which decreased after resolution.
