OCT angiography has improved the ability to identify silent or nonexudative neovessels in age-related macular degeneration. This promotes a rapid advancement in the diagnosis and in the necessity to expand our management decisions. This context is presented and the biomarkers are discussed.

Chronic central serous chorioretinopathy (cCSC) can produce an overlap of signs that can be difficult to distinguish from cases with non-exudative neovascular age-related macular degeneration (nneAMD). Around 2-10% of the patients with cCSC will develop neovascularization. Sometimes both diseases could be present at the same individual. The purpose of this narrative review is to discuss the current information concerning the signs in OCT angiography that eventually could help to differentiate these situations and analyze the best diagnostic evidence.

Fellow Eyes

We evaluated the spectrum of choriocapillaris (CC) abnormalities in the fellow eyes of unilateral exudative age-related macular degeneration (AMD) patients using swept-source optical coherence tomography angiography (SS-OCTA). Fellow eyes of unilateral exudative AMD patients were prospectively included between May 2018 and October 2018. Patients underwent a multimodal imaging including a SS-OCTA. Demographics and clinical findings were analyzed. The estimated prevalence of macular neovascularization (MNV) was computed. Number and size of flow deficits (FDs) and percentage of flow deficits (FD%) were computed on the compensated CC flow images with the Fiji software. We included 97 eyes of 97 patients (mean age was 80 ± 7.66 years, 39 males, 58 females). The prevalence of MNV in the studied eyes was 8.25% (8/97 eyes). In the 89 non-neovascular eyes, FD% averaged 45.84% ± 11.63%, with a corresponding total area of FDs of 4.19 ± 1.12 mm2. There was a higher prevalence of drusenoid pigment epithelial detachment in eyes with subclinical neovascularization (p = 0.021). Fellow eyes with unilateral exudative AMD encompassed a series of CC abnormalities, from FDs of the aging CC to subclinical non-exudative MNV.
