Fukushima A, Maruko I, Chujo K, et al. - In the present study, the researchers sought to discover the characteristics of eyes with treatment-naïve quiescent choroidal neovascularization (CNV) detected by optical coherence tomography angiography (OCTA). A total of 38 eyes from 37 treatment-naive patients (30 men, 7 women, average age 69.8 years) were examined. At the initial visit, all eyes with quiescent CNV were diagnosed with sub-retinal pigment epithelium CNVs, ie, type 1 CNV, from the OCT and OCTA images. During a two-year follow-up period, approximately 30% of the eyes with quiescent CNVs will develop exudation. Such findings must be remembered in the investigation of quiescent CNVs which could not be distinguished from eyes with former active CNV and naturally deactivated CNV.
