Where Does OCT Go From Here?

BioPhotonics
Mar 2017
Ophthalmology remains the primary application, but promising new uses in cardiology and dermatology are on the horizon.

OCT-A — optical coherence tomography angioplasty — which allows imaging without dye, is a promising breakthrough in the detection of early-stage glaucoma. And swept-source OCT has opened new possibilities for diagnosing diabetic retinopathy and early macular degeneration.

GLOSSARY
swept-source laser
A type of laser in which the output wavelength is adjustable over a wide range of wavelengths. The laser is focused on a particular wavelength and is “swept” over a range of wavelengths. This is useful for rapidly capturing spectral data, such as in spectroscopy and (especially) in Fourier-domain optical coherence tomography.
