Pachychoroid neovasculopathy in extramacular choroidal neovascularization

摘要

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.
