Optical Coherence Tomography (OCT)

Optical Coherence Tomography (OCT) is a diagnostic imaging technology that provides high-resolution, cross-sectional images of ocular tissues in real time. OCT works in a manner similar to ultrasound imaging, but instead of sound waves, it uses light waves to capture microscopic details of eye structures in fine detail. OCT systems image at high speed, taking many thousands of scans per second. This high speed enables precise three-dimensional and high-density mapping of the retina, macula, optic nerve, and cornea, supporting accurate diagnosis and monitoring of eye conditions. With a resolution reaching the micron level, OCT allows detailed evaluation of retinal layers, macular health, optic nerve integrity, and corneal measurements. Specialized imaging modes enhance visualization of different ocular tissues, making OCT an essential tool in diagnosing and following conditions such as glaucoma, macular degeneration, diabetic retinopathy, retinal edema, and in assessing patients after refractive eye procedures.
