Optical Coherence Tomography (OCT)
The OCT system is a new, non-invasive technology used for producing detailed cross-sectional images of the retina. This is the first instrument to assist doctors in revolutionizing the early detection and treatment of eye conditions such as macular holes, pre-retinal membranes, macular swelling and even optic nerve damage. OCT technology is also useful in diagnosing and monitoring glaucoma.
The OCT is much like ultrasound, except that it uses light beams instead of sound waves to rapidly scan the eye and describe a pixel representation of the anatomic layers within the retina. Each of the ten important layers of the retina can be differentiated and their thickness can be measured. These measurements assist the doctor in distinguishing a multitude of retinal diseases and related conditions.
