Layer-specific optimization of focusing using sensor-less AO with real-time image processing segmentation of retinal layers. (A) Focusing with a figure of merit based on the inner retina layers produces a cross-sectional OCT image with bright inner layers. (B) A figure of merit based on the entire B-frame bring the focus to the outer retina with its highly backscattering ellipsoid zone – retinal pigment epithelium complex. (C) Focusing on the inner retina optimizes the sharpness of retinal OCTA. (D) Focusing on the outer retina blurs the retinal OCTA. Field of view is 3.3×3.3 mm.
