Kim Boyer, The Ohio State University Automatic Measurement of Retinal Thickness and Optical Nervehead Geometry in Optical Coherence Tomography Abstract: Optical coherence tomography is a relatively new imaging technique providing high resolution, but noisy, cross sectional views of the retina. These images detail microscopic retinal pathology and provide objective, numerical measurements of retinal features in vivo. This talk describes our work over the past several years in the automated analysis of such images to characterize retinal thickness and to track thickness changes over time. We have also automated the extraction of optic nervehead geometry. Retinal thickness, and changes in the thickness over time, provide significant clues regarding ocular health and are especially important in the treatment of macular edema and glaucoma, both leading causes of preventible blindness. The optic nervehead geometry is also a strong indicator of eye health, particularly with respect to intraocular pressure and glaucoma. By bringing sophisticated models and computer vision techniques to bear on this problem, we have positioned Ohio State as the world leader in the automated analysis of retinal OCT.
