Neovessel as first manifestation of relapse of associated multifocal choroiditis and MEWDS

PURPOSE: To report a case of multifocal choroiditis (MC) that has relapsed as choroidal neovascularization in the contralateral eye followed by a mixed aspect of multiple evanescent white dot syndrome (MEWDS) and MC. METHODS: Retrospective case report and literature review. The clinical findings were documented by fluorescein angiography, optical coherence tomography, and optical coherence tomography angiography (OCT-A). RESULTS: The authors describe the case of a 39-year-old woman with prior ocular history of presumed MEWDS in her left eye, which developed into MC 7 years later in the same eye and 11 years later in the right eye, starting as choroidal neovascularization and developing into MEWDS. OCT-A showed neovessel in a supposedly active MC area outside the macular region in right and left eyes. OCT showed increased choroidal thickness in both eyes and a choroidal neovascularization in the right eye, treated using anti- VEGF therapy. CONCLUSION: This case corroborates the proximity of some inflammatory diseases such as MC and MEWDS. OCT-A has opened new horizons for the better understanding of some retinal diseases by providing more thorough and promising morphological analyses using enhanced tools.
