**4. Conclusions**

OCTA is a very promising image technique that is continually improving and offers numerous advantages over FA in DR management. Many clinical studies indicate their usefulness in early diagnosis, follow-up, identification of prognostic factors, and treatment of DR and related complications. Nevertheless, OCTA is a relatively new technique and the usefulness of most of the quantitative data it allows to obtain needs to be investigated. Finally, it would be important to have greater interchangeability between data offered by different software and improve image quality by reducing artifacts.
