Fujimoto, PhD, by David Huang, MD, PhD, then a Harvard Medical School, Cambridge, Massachusetts, and Massachusetts Institute of Technology, Cambridge, Massachusetts, Health Sciences Technology (HST) MD, PhD candidate, and Joel S. The first retinal imaging was performed in 1989 in the laboratory of James G. Given how pervasive OCT is in the clinical practice of ophthalmology, it is sobering to realize that the development of ophthalmic OCT began just under 20 years ago. A variety of case studies from glaucomatous and healthy eyes is also presented to illustrate the clinical utility and potential value of SD-OCT. To investigate the use of spectral domain OCT (SD-OCT), the most advanced OCT method available commercially for clinical use, a study was performed comparing the reproducibility and glaucoma discriminating ability of SD-OCT to time domain OCT (TD-OCT). This thesis aims to discuss the history and use of OCT as well as the future of OCT research.

3, 6 – 8, 10 – 31 It has also been used in the anterior segment of the eye 32 – 35 as well as to view the structure of nonocular tissues, including breast, 36 kidney, 37 and skin lesions, 38 – 43 among others. Because of the unique optically clear pathway through the eye, OCT has been used most extensively for imaging disorders affecting the retina. This method can be used to scan through the layers of a structured tissue sample such as the retina with very high axial resolution (3 to 15 μm), 1 – 10 providing images demonstrating 3D structure. Optical coherence tomography is a method of using low-coherence interferometry to determine the echo time delay and magnitude of backscattered light reflected off an object of interest. Many changes to the technology are still being made, improving axial and transverse resolution of the images and decreasing the time necessary for image acquisition. Out of a variety of techniques such as scanning laser polarimetry and confocal scanning laser ophthalmoscopy, optical coherence tomography (OCT) has emerged to the forefront of ocular imaging because of the wide variety of information it can provide, its high resolution, and the complex 3-dimensional (3D) data it is able to gather. Imaging of the eye has grown significantly in importance for the diagnosis of ocular diseases over the last 20 years.
