Ophthalmic ultrasound uses sound waves to reflect images off the surfaces of the eye such as the retina. In similar fashion, OCT uses light waves to accomplish the same thing, only with a resolution that is several hundred times greater. This has been likened to looking at the retina under a microscope, only it can be done in real time with the living eye.
OCT has completely revolutionized the way retina specialists diagnose, treat, and monitor diseases such as macular degeneration and diabetic retinopathy, among others. New England Retina Associates specializes in using the most up-to-date high-resolution OCTs and software available for cutting-edge imaging.
