Behavior of SD-OCT Detectable Hyperreflective Foci in Diabetic Macular Edema Patients after Therapy with Anti-VEGF Agents and Dexamethasone Implants

Figure 4

Treatment response of hyperreflective foci (HF) after dexamethasone implantation in a patient with diabetic macular edema (DME). Color fundus photograph (CFP), spectral-domain optical coherence tomography (SD-OCT) B-scan, and infrared image with Early Treatment Diabetic Retinopathy Study (EDTRS) grid depicting extent of DME (red and grey color) at baseline (left panel, day 0) and one month after dexamethasone injection (right panel, day 30) in the same patient as in Figure 1. HF are found adjacent to cystoid spaces in the outer retinal layers. After therapy, the DME resolved and the number of HF clearly decreased.
