AUTOMATED RETINAL LAYER SEGMENTATION AND THEIR THICKNESS PROFILES IN HEALTHY SUBJECTS: A Comparison of 55° Wide-field and Conventional 30° Spectral Domain-Optical Coherence Tomography

Purpose: To assess whether retinal thickness measurements with a standard 30° spectral domain optical coherence tomography (SD- OCT ) are comparable with wide-field 55° SD- OCT . Methods: Thirty-three healthy individuals were scanned using 55° as well as 30° SD- OCT according to a standardized protocol. Automated retinal layer segmentation of standard and wide-field SD-OCTs was assessed using customized software. Results: Both lenses showed a high correlation when analyzing total retinal thickness within the central, the inner, and the outer retinal ring (r = > 0.9). Automated thickness measurements with the 55° system were marginally higher compared with the 30° lens. The thickness ...
