Summary PURPOSE:To determine the characteristics of eyes with treatment-naïve quiescent choroidal neovascularization (CNV) detected by optical coherence tomography angiography (OCTA).METHODS:Thirty-eight eyes of 37 treatment-naïve consecutive patients (30 men, 7 women, average 69.8 years) were studied. Quiescent CNVs were detected by OCTA (RTVue XR Avanti, Optovue, Fremont, CA) in all eyes. Swept-source OCT (SS-OCT; DRI-OCT, Topcon, Japan) confirmed the absence of exudation. The symptoms, visual acuity, CNV size, and status of the fellow eye were evaluated. Patients were followed longitudinally and the length of follow-up period and development of exudation were recorded for each patient. We also investigated patients' medical records from their referral hospitals in search of prior exudation.RESULTS:All eyes with quiescent CNV were diagnosed at the initial visit with sub-retinal pigment epithelium CNVs, i.e., type 1 CNV, from the OCT and OCTA images. Prior exudation was confirmed in 15 eyes (39.5%) from their medical records of the referral hospitals. Symptoms were present in 18 eyes (47.3%). An exudative CNV was present in 12 of the fellow eyes. Exudation developed in 12 eyes (31.6%) during an average follow-up period of 25.1 months. One-half of the eyes had a prior exudation. The CNV at the baseline in eyes that developed exudation during the follow-up period was larger than eyes without exudation; however, the difference was not significant (0.59±0.47 vs 0.48±0.32 mm2, P = 0.50).CONCLUSION:Quiescent CNVs will develop exudation in approximately 30% of the eyes during a mean 2-year follow-up period. These findings must be remembered when investigating quiescent CNVs that could not be distinguished from eyes with former active CNV and naturally deactivate CNV.
