Pachychoroid neovasculopathy in extramacular choroidal neovascularization

PURPOSE To review a series of extramacular choroidal neovascular membranes (CNVMs) in the context of their choroidal features, as determined by optical coherence tomography (OCT). METHODS Patients with extramacular CNVMs were identified from a tertiary care center through a review of records. The charts and cases were reviewed using multimodal imaging including fundus photography, OCT, fluorescein angiography (FA), and indocyanine angio-graphy (ICG). RESULTS Of six patients with extramacular CNVMs evaluated in this series, four patients (66.7%) exhibited pachychoroidopathy on OCT imaging under or adjacent to the extramacular CNVM. All four of these patients also exhibited pachychoroidopathy in the macular OCT distant from the CNVM. CONCLUSION Pachychoroidopathy is implicated in some cases of extramacular CNVMs. This represents the first report, to our knowledge, of pachychoroidopathy in extramacular CNVM.
