New Diagnostics: What Is the Role of OCT Angiography in Assessing Glaucoma?

OCT-A is a novel, noninvasive imaging technology that allows glaucoma clinicians to evaluate tissue perfusion with high precision. OCT-A is implemented on ordinary OCT devices, which are economical and widely accessible. This technology could be used to measure glaucomatous changes in the perfusion of the macular and peripapillary retina. Although clinical data on this new technology are still limited, preliminary results show the potential for earlier glaucoma diagnosis and improved monitoring of disease progression rate. Recent advances in commercial instrumentation have made it possible for any clinician to begin using this powerful new tool in their practice.
