  1. OCT: Optical coherence tomography; SRF: Subretinal fluid; IHRF: Intraretinal hyper-reflective foci; EZ, Ellipsoid zone; ERM: Epiretinal membrane; ELM, External limiting membrane; DRIL: Disorganization of retinal inner layers
  2. Assessed with the Fleiss’ kappa (κ) statistic
  3. Strength of agreement was determined by the following scale: Poor < 0.20; Fair 0.21–0.40; Moderate 0.41–0.60; Good 0.61–0.80; Very good 0.81–1.00
