Structural Changes in Individual Retinal Layers in Diabetic Macular Edema
Figure 1
(a) Retinal sections of the physiologic macula dissecting along the green line on fundus photography using SD-OCT. (b) The magnified image at the fovea shows three lines over the retinal pigment epithelium (RPE), that is, the external limiting membrane (ELM), the junction between inner and outer segments (IS/OS), and the cone outer segment tips (COST). (c) A magnified parafoveal image shows the individual retinal layers. NFL: nerve fiber layer; GCL: ganglion cell layer; IPL: inner plexiform layer; INL: inner nuclear layer; OPL: outer plexiform layer; ONL: outer nuclear layer.
