Optical coherence tomographic angiography (OCTA) is the most important new clinical OCT technology in the past decade. It became available as a clinical instrument in 2014. Since then it has been applied to a wide range of retinal and optic nerve diseases. This presentation will review the current state of the art and key clinical applications. I will also report on the development of several novel OCT technologies in our laboratory that may have important clinical applications in the near future.
