PURPOSE: To evaluate the long-term outcomes of adjunctive surgical procedures during pars plana vitrectomy (PPV) for the treatment of diabetic macular edema (DME). METHODS: In this nonrandomized study, we retrospectively analyzed 57 eyes of 54 patients who had DME and had undergone PPV. We performed PPV using three different surgical procedures: conventional PPV (group PVD; 13 eyes), triamcinolone acetonide (TA)-assisted PPV (group TA; 22 eyes), and TA-assisted PPV combined with internal limiting membrane (ILM) peeling (group ILM; 22 eyes). We also evaluated the preoperative and postoperative best-corrected visual acuity (BCVA) results. RESULTS: The overall mean preoperative BCVA was 0.86 logarithm of the minimal angle of resolution unit. In groups PVD, TA, and ILM, BCVAs were 0.99, 0.90, and 0.74 (P = 0.310), respectively. The mean postoperative BCVA for all patients improved to 0.68 (P = 0.005). The postoperative BCVA improved in 47% of the treated eyes, it remained unchanged in 37% of the treated eyes, and it deteriorated in 16% of the treated eyes. However, we observed no significant difference in the mean postoperative BCVAs between the three groups. Furthermore, we found that there was no significant difference in postoperative BCVA improvements between any of the groups (P = 0.450). CONCLUSION: The present study suggests that these 3 PPV approaches do not significantly affect postoperative BCVAs after 18 months of DME treatment.
