Spectral-domain OCT

Spectral-domain optical coherence tomography (SD-OCT) is a medical imaging technique that uses light to capture detailed images of internal structures in the eye, such as the retina. It works by splitting a light beam into two: one directed at the eye and the other as a reference. The reflected light is then analyzed to create cross-sectional images, allowing doctors to see layers within the eye with high resolution. This non-invasive approach helps in diagnosing and monitoring conditions like glaucoma and macular degeneration, ultimately aiding in better treatment decisions.
