Increase in Capillary Plexus Density Level Following the Use of Ozurdex for the Treatment of DME

Increase in Capillary Plexus Density Level Following the Use of Ozurdex for the Treatment of DME (RMSM ICOD STUDY)

The objective of this study is to test the hypothesis that following the use of intravitreal dexamethasone implant for the treatment of DME, there will be an observable increase in the capillary density plexus as denoted by the quantitative assessment of the superficial capillary plexus on OCTA, as well as a decrease in size of the foveal avascular zone (FAZ).
