Cellular and Functional Optical Coherence Tomography of the Human Retina (The Cogan Lecture)

submitted by: arvojenny
An imaging modality that allows for fast, simultaneous, noninvasive probing of both three-dimensional (3D) cellular resolution retinal morphology and depth-resolved function could substantially improve the early diagnosis of various retinal diseases that are the leading causes of blindness worldwide and could contribute to a better understanding of retinal pathogenesis and enhanced therapy monitoring. In addition to user friendliness, reliability, and cost, the key technological parameters...
