Spectral Domain Optical Coherence Tomography-Based Imaging Biomarkers and Hyperspectral Imaging
Biomarkers, are biochemical or imaging parameters, that objectively indicate the state of health of an individual. These are measurable by laboratory assay or medical imaging and are useful in prognosticating the disease and monitoring the effects of therapeutic interventions. Spectral domain optical coherence tomography has proved useful in identifying various imaging biomarkers in a range of ocular diseases. Hyperspectral imaging, a novel technology, collects information from across the electromagnetic spectrum for every pixel in an image. Hyperspectral imaging of the retina identifies materials or detects biochemical and metabolic processes within the retina. It provides a feasible method for measurement and analysis of vascular oxygen content in healthy and diseased retina.
