A standard look into the eye shows the surface of the retina. OCT, which stands for optical coherence tomography, goes further. It captures a detailed cross section so we can see the individual layers of the retina and the optic nerve, much like an ultrasound but using light.
That extra detail matters because many serious eye conditions cause no symptoms in their early stages. By the time vision is affected, more damage has often already happened. OCT lets us spot those changes early, when there is the most we can do to protect your sight.
