coherence tomography

Optical coherence tomography (OCT) is a non-invasive imaging technique that uses light waves to capture detailed, cross-sectional images of the internal structures of the eye, particularly the retina. It works like an ultrasound but with light instead of sound, providing high-resolution images that help eye doctors assess and diagnose conditions such as macular degeneration, glaucoma, or diabetic retinopathy. OCT allows for precise measurement of retinal layers and tissue thickness, enabling early detection and effective monitoring of eye diseases without discomfort or the need for invasive procedures.
