Abstract : The research results, supported by Air Force Grant #F49620-93-1-0337 (1), have been successful in obtaining the above objectives. Research supported by this grant has lead to significant advancement in the area of optical coherence tomography (OCT). In brief, OCT represents a new and valuable diagnostic technique for high-resolution; noncontact imaging of the human eye including the retina and cross-sectional imaging of structures in the anterior segment. Optical coherence tomography is analogous to ultrasound, except that optical rather than acoustic reflectivity is measured. This new optical imaging modality has spatial resolution superior to that of conventional clinical ultrasonography (<20un) and high sensitivity (dynamic range,>90db). OCT is proving to be a powerful tool for detecting and monitoring a variety of diseases of the eye including a variety of macular diseases, such as macular edema, macular holes, and detachments of the neurosensory retina and pigment epithelium.
