2.1. Images Detection

After completing OCT scans of the entire area within the vascular arcades, the fundus was investigated using fundus photography, FAF and retromode imaging. The OCT acquisition protocol consisted of a 6 × 6 mm (mm) three-dimensional vertical scanning area, centered on the fovea comprising 512 × 128 scans. Color photos from Nidek Mirante had a 45-degree field of view with a resolution of 1024 × 720 pixels. Three separate laser wavelengths (red—670 nm, green—532 nm, blue—488 nm) are combined to create color pictures, which are then connected to a specific sensor for each wavelength. A blue-light excitation wavelength of 488 nm (emission > 500 nm) is used to obtain fundus autofluorescence (FAF), whereas the retromode imaging system uses an infrared laser light (790 nm). A right-deviated aperture and a left-deviated aperture were used to obtain two separate retromode pictures per eye. All the tomographic images were acquired, averaging up to 30 frames per image.
