    Managing glaucoma with OCTA

    How can OCTA be employed in routine glaucoma management?

    Optical coherence tomography angiography (OCTA) is a new imaging technique that has the potential to move rapidly into routine clinical practice. OCTA comprises different OCT-based technologies, which enable the non-invasive assessment of retinal perfusion, based on red blood cell movement in the optic nerve head, the peripapillary and the macular retina.

    In addition to the benefits offered by the non-invasive nature of OCTA over invasive fluorescein angiography in macular diseases, including age-related macular degeneration and diabetic macula oedema, OCTA has been increasingly investigated for use in the detection of glaucoma and understanding the role of vascular alterations in the development of open-angle glaucoma.

    OCTA of the disc and peripapillary retina is available with a variety of OCTA instruments, although measurement results are currently not provided by all systems and it is not possible to convert results between the different systems.
