WebA major cause of vision loss in patients with diabetes is diabetic macular edema (DME) and diabetic macular ischemia (DMI). DME can manifest itself on OCT in a variety of ways, including sponge-like swelling, cystoid macular edema, and subfoveal neuroretinal detachment. Macular perfusion status is important for visual function. WebThe cause of foveal atrophy is multifactorial and may include dysfunction and atrophy of the retinal pigment epithelium and choroid, cystoid macular edema, macular ischemia secondary to occlusive retinal vasculitis, choroidal neovascularization, retinal detachment, and possibly antibody-mediated damage directed against photoreceptors.
