This course will provide an update and thorough understanding of the flash flicker electroretinogram (ffERG), proper indications and protocols, and how to interpret the results. Diabetic retinopathy has historically been evaluated and followed with structural tests (DFE's, OCT's and fundus photos), this lecture will explore functional testing (ERG) and newer OCT testing (OCT-A) that helps in the evaluation of diabetic patients, and will also discuss the newest literature in regards to supplementation of diabetic retinopathy patients.   

LEARNING OBJECTIVES:
• To become familiar with the flash flicker ERG (ffERG) and its role as an objective functional test in diabetic retinopathy

• To review the role of nutritional supplementation in diabetic retinopathy

• To review the DIvFUSS study

• To go through actual cases showing ffERG results and nutritional supplementation effects
