Optical Coherence Tomography (OCT) is a non-invasive imaging test that provides highly detailed, cross-sectional images of the retina. At Dr. Poonam Acharya’s clinic, this advanced diagnostic technology helps in the early detection and precise monitoring of eye conditions affecting the retina, macula, and optic nerve. By using light waves instead of sound or radiation, OCT delivers micrometer-level accuracy — allowing Dr. Acharya to visualize every retinal layer and detect changes long before symptoms appear.
