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.
