Purpose: To evaluate the effects of a single injection of Ozurdex over 6 months in eyes with persistent diabetic macular edema (DME). Methods: In this retrospective interventional study, 9 patients with decreased visual acuity, as a result of persistent DME, received Ozurdex (intravitreal dexamethasone implant 0.7 mg). Main outcome measures included changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT). Results: Nine eyes of 9 patients (5 males, 4 females; mean age 58 years) were included in the analysis. The mean duration of DME was 49.9 months (range 24-85). All patients had undergone previous treatments for DME (intravitreal injection of anti-vascular endothelial growth factor, steroids or laser photocoagulation) before entering the study. At baseline, the mean BCVA was 0.74 +/- 0.33 logMAR, and the mean CRT was 502 +/- 222.16 mu m. The mean BCVA was unchanged on the third day (0.74 +/- 0.38 logMAR, p = 0.5), improved to 0.62 +/- 0.32 logMAR (p = 0.02), 0.59 +/- 0.26 logMAR (p = 0.02) and 0.63 8 0.38 logMAR (p = 0.6) after the first, third and fourth months, respectively, and decreased again to 0.73 +/- 0.35 logMAR (p = 0.4) at 6 months. The mean CRT improved to 397 +/- 115.31 mu m (p = 0.17), 271 +/- 99.97 mu m (p = 0.007), 325 +/- 133.05 mu m (p = 0.03) and 462 +/- 176.48 mu m (p = 0.36) on the third day and after 1, 3 and 4 months of follow-up and then increased again to 537 +/- 265.42 mu m (p = 0.33) at 6 months. Eight patients needed retreatments in the sixth month. One eye developed a transient intraocular pressure (IOP) increase 1 month after injection, which was successfully managed with topical IOP-lowering medication. Conclusion: In eyes with persistent DME, Ozurdex produces improvement in BCVA and CRT as soon as the first days after the injection. Such improvement is maintained until the fourth month.
