Spectral domain-Optical coherence tomography (SD-OCT) provides information about the in-vivo histology of the retina. Diabetic retinopathy is associated with structural changes within the retina. Recently, disorganization of the inner retinal layers has also been shown to correlate with the final visual outcome.These changes can be observed by OCT, and correlate with the visual acuity. Accurate evaluation of the second hyper reflective band in the macular region, Ellipsoid Zone, on OCT is highly significant for providing valuable information regarding disease state and visual prognosis in diabetic
