Optical Coherence Tomography Angiography of Diabetic Retinopathy

Purpose: To describe the optical coherence tomography angiography (OCTA) features of diabetic retinopathy.

Methods: Literature review and case series.

Results: Four cases are presented.

Conclusion: OCTA is an effective method for evaluating retinal changes in diabetic retinopathy and represents a novel complement or alternative to fluorescein angiography. Although OCTA should currently be considered an investigational technique, in the near future, it may play key roles in the diagnosis and management of diabetic retinopathy.
