Optical frequency domain imaging of human retina and choroid

Optical coherence tomography (OCT) has emerged as a practical noninvasive technology for imaging the microstructure of the human eye in vivo. Using optical interferometry to spatially-resolve backreflections from within tissue, this high-resolution technique provides cross-sectional images of the anterior and posterior eye segments that had previously only been possible with histology. Current commercially-available OCT systems suffer limitations in speed and sensitivity, preventing them from effective screening of the retina and having a larger impact on the clinical environment. While other technological advances have addressed this problem, they are inadequate for imaging the choroid, which can be useful for evaluating choroidal disorders as well as early stages of retinal diseases. The objective of this thesis was to develop a new ophthalmic imaging method, termed optical frequency domain imaging (OFDI), to overcome these limitations. Preliminary imaging of the posterior segment of human eyes in vivo was performed to evaluate the utility of this instrument for comprehensive ophthalmic examination.
