Characterization of Outer Retinal Morphology with High-Speed, Ultrahigh-Resolution Optical Coherence Tomography

1. purpose. To visualize, quantitatively assess, and interpret outer retinal morphology by using high-speed, ultrahigh-resolution (UHR) OCT.
   methods. Retinal imaging was performed in the ophthalmic clinic in a cross-section of 43 normal subjects with a 3.5-µm, axial-resolution, high-speed, UHR OCT prototype instrument, using a radial scan pattern (24 images, 1500 axial scans). Outer retinal layers were automatically segmented and measured. High-definition imaging was performed with a 2.8-µm axial-resolution, high-speed, UHR OCT research prototype instrument, to visualize the finer features in the outer retina.
   results. Quantitative maps of outer retinal layers showed clear differences between the cone-dominated fovea and the ... (Read Full Article)
