Figure 2
Representative case showing the parafoveal cystoid space at Segment 1/no fluid at Segment 2 type of diabetic macular edema. (A–C) En face images of the retinal surface (A), Segment 1 (B), and Segment 2 (C) are presented. Epiretinal membrane (arrowheads in A) and associated retinal folds (arrows in A) can be observed at the surface of the retina (A). There are cystoid spaces at Segment 1, with fluid remaining within the parafovea (arrowheads, B). There is no fluid at Segment 2 (C). (D–F) B-scan images and the green lines show the locations at which the en face images of the retinal surface (D), Segment 1 (E), and Segment 2 (F) were generated. The scan depth, indicated by the distance between the green line and green dotted line, was set to 0 μm for the en face image of the retinal surface (D) and 50 μm for the en face images of both Segments 1 and 2 (E,F, respectively). (G) A horizontal B-scan image centered at the fovea is presented. Parafoveal cystoid spaces are located at both Henle’s fiber layer (arrows) and the inner nuclear layer (dotted arrows). The arrowheads in (G) indicate the epiretinal membrane.
