Quantitative Curvature Maps of the Ocular Posterior Segment Utilizing OCT with Demonstration of Local Shape Change over Time (conference Presentation)

Ocular morphological deformations, such as scleral flattening due to high intracranial pressure, result in both global and more difficult to detect local changes. Local curvature analysis of the retinal profile could help in the visualization of retinal morphological deformations. Using a wide-field, whole eye OCT system, we demonstrate quantitative local, meridional retinal curvature maps across a 12 mm field-of-view. Because our method provides absolute (instead of relative) quantitative maps of local curvature, comparisons can be made directly between individuals. Additionally, retinal topography could help clinicians detect subtle, local retinal deformations earlier in patients and track changes over time.
