Optical coherence tomography for assessment ofdiabetic macular edema

Optical coherence tomography (OCT) is a noninvasive objective diagnostic technique that has become a powerful method for the clinical assessment of diabetic macular edema. It is a very useful imaging technique to diagnose and follow-up diabetic macular edema (DME). The present paper aims to present an overview of the principles, progress, and uses of OCT in the diagnosis and management of DME.
