A prospective case-control study was undertaken to evaluate the association of inner segment-ellipsoid (ISel) band disruption with severity of diabetic retinopathy on spectral-domain optical coherence tomography. ISel disruption was graded as - grade 0: intact ISel; grade 1: focal disruption (subfoveal ISel disruption) and grade 2: global disruption (ISel disruption involving macular cube). Increased severity of diabetic retinopathy was found to be associated with increase in disruption of ISel (r = 0.49, p < 0.001).
