  1. Data are presented as mean ± standard deviation.
  2. BCVA best-corrected visual acuity, CMT central macular thickness, EIFL ectopic inner foveal layer.
  3. a Aniseikonia was analyzed for unilateral affected eyes; 7 patients (6 with epiretinal membrane (ERM) and 1 with branch retinal artery occlusion) in group 1, 9 patients (6 with ERM, 1 with neovascular age-related macular degeneration, 1 with central retinal vein occlusion, and 1 with anophthalmos) in group 2, and 7 patients (7 with ERM) in group 3 were excluded due to pathologic condition in the macula of the fellow eyes.
