4. OCT (Optical Coherence Tomography)
OCT is probably one of the most (if not the most) significant advances in ophthalmic imaging in our recent history. Incredibly, we are able to capture anatomical images from basically every part of the eye with OCT technology including the retina, optic nerve, and anterior segment.
While initially conceived in 1991, it wasn’t until 2002 when time-domain OCT was introduced that this imaging modality truly started its journey to clinical utility.3 Later, with the advent of spectral domain OCT (2004-2007), widespread usage among ophthalmologists rose considerably and now is one of the most common ophthalmic imaging tests performed in the world.
