The Science Behind Optical Coherence Tomography in Modern Eye Care
Optical coherence tomography has changed the way eye doctors see the retina, the optic nerve, and the delicate layers that sit at the back of the eye. A generation ago, much of that work depended on indirect clues, photographs, and clinical experience stitched together over time. Today, optical coherence tomography, often shortened to OCT, gives a cross-sectional view of tissue in seconds. It does not replace a careful exam, but it adds a level of precision that has become
