In the published article, there are few changes requested by the author. The changes are as follows: In section “Multifocal electroretinogram (mfERG) and its responses in myopia”—last sentence of 2nd paragraph should read as: “In humans, the N1 component primarily originates from the ON- and OFF-cone bipolar cells with minimal contribution from the cone photoreceptors.” In addition, the following figure captions and table footntoes should read as follows: Figure 2: Panel A: The b-wave amplitudes plotted against the moderate (MM) and high myopia (HM) are those associated with moderate and advanced chorioretinal degeneration, respectively, within the group of pathological myopes (PM) studied [119]. Panel A and B: These older studies used non-standard stimuli, strong flashes in dark-adapted participants, and such amplitudes are more comparable to those in panels G and H dark-adapted ‘combined’ ERGs. Panel D: Should be labeled “Combined ERG” as Wan et al [122] used the ISCEV Standard dark-adapted 3.0 stimulus. A revised figure (2S) with corrected labels is available in the electronic supplemental material. Figure 4: Panels E, H, and I: The y-axis in these panels is microvolt (μV), not conventional density units (nV/deg 2). (The angular size of the stimulus elements for conversion to density are not available.) Table 1: Several studies in this table used nonstandard ERG protocols or extended protocols [119, 112, 113, 122]; The study by Ishikawa et al. [120] used a focal macular ERG protocol Tables 1–3: Some details of the stimuli and participants are omitted from tables. Tables 1S, 2S and 3S in the electronic supplement include the omitted information to allow clearer comparisons between studies.
