Figure 13: (a and b) Spectral domain optical coherence tomography pre- and post-treatment for diffuse diabetic macular edema. There is diffuse intraretinal fluid with cysts and schisis (yellow arrow). Both the thickening and the detachment are seen to reduce after intravitreal anti vascular endothelial growth factor injection. (c and d) Spectral domain optical coherence tomography images of varying severity of diabetic macular edema. Intraretinal cystic spaces are seen in the inner nuclear layer and Henle's layer (yellow arrowhead) with subfoveal detachment (blue star). (e) Spectral domain optical coherence tomography image of diabetic macular edema with diffuse retinal thickening (yellow arrow), intraretinal hyper reflective echoes and a significant amount of subretinal fluid (blue star). There is an area of irregularly elevated retinal pigment epithelium in the subfoveal region which showed a central serous chorioretinopathy leak on fundus fluorescein angiography (yellow arrow) |
