Ellipsoid Zone Integrity and Visual Acuity Changes during Diabetic Macular Edema Therapy: A Longitudinal Study

Figure 1

(a) Overview of regions of interest (ROI). In total, 27 measurements in 200 μm distance of each OCT B-scan were obtained and analyzed. (b) shows a representative longitudinal reflectance profile at each ROI. Pixel intensity values ranged from 0 (black) to 255 (white) on gray scale. Maxima values (“peaks”) are represented by red dots and minima values between the peaks that are represented by blue dots.
