    OCTA: Future Is bright, fast, and wide in ROP

    Optical coherence tomography angiography (OCTA) is a new technology that is gaining importance in ophthalmology clinics as new capabilities are being determined.

    Dr. Campbell

    Patients with diabetic macular edema and macular degeneration have benefited from its use, and interest is focusing on the use of OCTA in patients with retinopathy of prematurity (ROP).

    OCTA has several advantages over fluorescein angiography (FA), in that the former is noninvasive, can resolve the macular plexuses in better resolution than FA, and can provide objective metrics of disease severity, most commonly vessel density or areas of flow void, according to J. Peter Campbell, MD, MPH.

    However, no technology is the be all and end all, and OCTA is no exception. Dr. Campbell pointed out that the commercially available OCTA devices provide only a narrow field of view, are limited by artifact, and hand-held OCTA devices are unavailable, which has limited the use of OCTA in children.

    Dr. Campbell is assistant professor of ophthalmology, Casey Eye Institute, Oregon Health & Science University, Portland.
