In what year was OCT introduced?

• A. 1981
• B. 1991
• C. 2001
• D. 2011

Answer: (B)

OCT was introduced in 1991 through the first demonstration of time-domain optical coherence tomography, which produced the first cross-sectional, in vivo images of tissue. This milestone established OCT as a real imaging modality and opened the door to its rapid use in ophthalmology and other fields. Earlier years didn’t have a viable OCT technique, while later years reflect major improvements (like spectral-domain or swept-source OCT) that came after the initial introduction.
