Abstract

Purpose To describe the characteristics and natural history of quiescent choroidal neovascularization (CNV) in geographic atrophy (GA) secondary to nonexudative age-related macular degeneration (AMD) through multimodal imaging. Design Retrospective observational case series. Methods Patients diagnosed with quiescent CNV were analyzed in 2 high-volume referral centers. Imaging features obtained using fluorescein angiography (FA), indocyanine green angiography (ICGA), structural optical coherence tomography (OCT), and OCT angiography (OCT-A) were noted at first presentation and during the study period. Results Nineteen eyes of 19 patients were included. Mean (+SD) follow-up was 45.7 ± 14.7 months. Quiescent CNV appeared as an ill-defined hyperfluorescent lesion without leakage or pooling of dye in the late phase of FA. On ICGA, quiescent CNV appeared as a distinct area of hyperfluorescence (vascular network) in early to intermediate frames and as a hyperfluorescent plaque in the late frame (late plaque). OCT-A revealed a flow signal beneath the small irregular elevation of the retinal pigment epithelium at the site of the quiescent CNV visualized by structural OCT. During the study period, 5 of the 19 CNV patients developed exudation. The remainder showed specific alterations in both structural OCT and OCT-A imaging. At last follow-up, 92% of the quiescent CNV seemed to cover the area spared from atrophy. Conclusions The characteristics of the quiescent CNVs were very similar to those already described for intermediate AMD, although they had several specific features in the context of GA. © 2017 Elsevier Inc.
