Optical coherence tomography (OCT) is a non-invasive imaging technique that uses light to capture high-resolution, cross-sectional images of biological tissues. It is commonly used in ophthalmology to visualize the layers of the retina, optic nerve head, and cornea, providing valuable information for diagnosing and monitoring eye diseases such as macular degeneration, glaucoma, and diabetic retinopathy. OCT is also used in other medical specialties, such as cardiology and dermatology, for imaging blood vessels and skin layers, respectively. The technology has revolutionized medical imaging by enabling detailed visualization of structures within the body without the need for invasive procedures.
