    Quantitative topographic curvature maps of the posterior eye utilizing optical coherence tomography

    Purpose: Deformations of the retina such as staphylomas in myopia or scleral flattening in high intracranial pressure can be challenging to quantify with en face imaging. We describe an OCT based method for the generation of quantitative posterior eye topography maps in normal and pathologic eyes. Methods: Utilizing “ whole eye ” OCT we corrected for subjects’ optical distortions to generate spatially accurate posterior eye OCT volumes and created local curvature ( K M , mm -1 ) topography maps for each consented subject. We imaged nine subjects, three normal, two with myopic degeneration (MD), and four with papilledema including one that was imaged longitudinally ...
