Optical Coherence Tomography (OCT)
High-resolution imaging of the retina, cornea, or other tissues using light waves.
OCT uses near-infrared light to produce cross-sectional images of biological tissue. It's standard in ophthalmology (retinal disease, glaucoma) and increasingly used in cardiology (coronary OCT).
What this means for you: for retinal disease and glaucoma decisions, OCT findings drive intervention timing. Bring recent OCT scans on disc.
What a term means for you depends on your own reports. Ask your treating doctor, or send your reports for a free review.
