Postoperative changes in central macular thickness (a, b) and average, horizontal, and vertical metamorphopsia scores (c-h) according to the active peeling of residual ILM (group 2, active peeling; group 3, non-peeling) in eyes with residual ILM not involving the fovea (pattern B) and involving the fovea (pattern C and D). Blue asterisks indicate significant differences between Group 2 and Group 3, and black hashes indicate significant differences between Group 2 and Group 3 patients without ERM recurrence (p < 0.05). Error bar indicates standard deviation.
