In the original article, there was a mistake in [**Figure 2F**](#f2){ref-type="fig"} as published. The wrong image was included due to the incorrect labeling of a file. The correct [**Figure 2**](#f2){ref-type="fig"} appears below.

![FPR2 and RvD1 levels, cell viability, ROS content, NF-kb protein expression. **(A)** ELISA detecting the levels of FPR2 receptor and **(B)** constitutive Resolvin D1 before and after RvD1 addition to photoreceptors exposed to high glucose; **(C)** XTT assay for determination of total cell number; **(D, E)** average intensity from DCFH-DA for total intracellular ROS levels compared to a negative control (yellow) and a positive control (fill red, 100 μM H2O2). Green = normal glucose; black = high glucose; blue = HG + RvD1 and red = HG + RvD1 + Boc2; **(F)** Western Blotting determination and representative images of NFκB protein levels into photoreceptors stimulated with normal glucose (5 mM D-glucose); high glucose (30 mM D-glucose); HG + RvD1 (RvD1, 50 nM); HG + RvD1 + Boc2 (20 μM). Values are expressed as mean ± s.e.m. of n = 9 values, obtained from the triplicates of three independent experiments. They were analyzed by one-way ANOVA followed by Bonferroni's test for each panel, except for panel **(B)** were ANOVA for repeated measures was applied.

In addition, there was a mistake in [**Figure 7**](#f7){ref-type="fig"}. Incorrect panels were included in [**Figures 7B, C**](#f7){ref-type="fig"}. The corrected [**Figure 7**](#f7){ref-type="fig"} appears below.

Finally, there was a mistake in [**Figure 9**](#f9){ref-type="fig"} where the first two and last columns were mislabelled. The corrected [**Figure 9**](#f9){ref-type="fig"} appears below.

![Representative images of the tubular structures and node formation from transfected HUVEC cells. **(A)** Matrigel natural views, **(B)** dark field Matrigel views, and **(C)** Matrigel graphical images of HUVEC cells grown in normal glucose (NG, 5 mM) after the silencing of miR-20a-5p, miR-20a-3p, miR-20b, and miR-106a-5p in these cells.
