OCT (Optical Coherence Tomography) system is a non-invasive ophthalmic imaging device used to capture high-resolution, cross-sectional images of the retina, optic nerve, and other structures within the eye. It uses light-based imaging technology to help eye-care professionals identify and monitor conditions such as glaucoma, macular degeneration, diabetic eye disease, and retinal disorders. OCT systems provide detailed structural information, supporting accurate diagnosis, treatment planning, and ongoing patient monitoring in ophthalmology and optometry practices.
