Increased field-of-view full-field OCT for 3D high-resolution retinal imaging (Conference Presentation)

Paper Abstract

To achieve 3D high-cellular resolution, a great effort, in the past years, was made to develop Adaptive Optics (AO)-OCT systems. However, such systems require quite complex, expensive and cumbersome hardware, making clinical transfer challenging. Moreover, conventional AO correction is limited to the retina isoplanatic patch (about 1deg), reducing the useful field of view (FOV). Recently, we showed the potential of Time Domain Full-Field-OCT (FF-OCT) to achieve 2deg FOV high-cellular-resolution in-vivo retinal imaging without using AO. Nevertheless, the technique was still facing some challenges in providing consistent and reproducible images (mainly due to axial eye motion), and it presented a reduced signal and FOV. Here, we present the new generation of FF-OCT system with axial eye motion tracking. We show new results and methods to minimize dispersion and coherence gate curvature enabling achieving 4deg (potentially 8deg) FOV high-cellular-resolution retinal images.
