Abstract
INTRODUCTION To evaluate real-world efficacy, safety, and treatment patterns with the dexamethasone intravitreal implant (DEX) in diabetic macular edema (DME) in France. METHODS In this prospective, multicenter, observational, noncomparative, post-reimbursement study, consecutively enrolled patients with DME had a baseline evaluation on day 0. Those treated with DEX on day 0 were to be reevaluated at week 6 and months 6, 12, 18, and 24. DEX retreatment and/or alternative therapies were allowed during follow-up. The primary outcome measure was the maximum best corrected visual acuity (BCVA) gain from baseline during follow-up. Secondary outcome measures included time to maximum BCVA gain, patients (%) with prespecified BCVA gains from baseline at each visit, maximum central retinal thickness (CRT) reduction from baseline, patients (%) with CRT reduction ≥ 20% from baseline at each visit, patients (%) with DME resolution (per investigator judgement), and adverse events (AEs). RESULTS Of 112 patients/eyes with DME for 3.5 years (mean) at baseline, 80 (including 86.1% previously treated) received DEX on day 0 and were analyzed for efficacy. Early study termination precluded collection of ≥ 12-month efficacy data. Patients received 1.4 DEX injections over 8.3 months (averages). The maximum BCVA gain from baseline was 3.6 letters, reached after 77.2 days (averages); 24.6% (week 6) and 15.0% (month 6) of patients experienced ≥ 10-letter BCVA gains from baseline. The mean maximum CRT reduction from baseline was -146.4 µm; 61.4% (week 6) and 36.0% (month 6) of patients had CRT reductions ≥ 20% from baseline, and 68.1% reported DME resolution at least once during follow-up. Ocular hypertension (n = 8, 12.1%) was the most frequent treatment-related AE. CONCLUSIONS LOUVRE 3 confirmed that DEX improves BCVA and CRT, even in a patient population that had predominantly received DEX before enrollment in the study, and showed that DME resolution was observed during follow-up. DEX tolerability was consistent with published data, supporting treatment benefits in DME. CLINICALTRIALS GOV IDENTIFIER NCT03003416.

Abstract
PURPOSE Comparison of the efficacy of monthly anti-VEGF versus dexamethasone (DEX) implant in patients with diabetic macular edema (DME) whose macular edema persists despite three doses of anti-VEGF therapy. MATERIALS AND METHODS This retrospective study included 94 eyes of 94 patients with central macular thickness (CMT) > 300 μm despite previously receiving three doses of anti-VGEF (aflibercept or ranibizumab) injections between January 2014 and January 2019. The patients were divided into four groups. The first and second groups were the patients who received three more doses of initial anti-VGEF treatment after the initial anti-VGEF treatment. The third and fourth groups were patients switched to intravitreal dexamethasone implants. Patients were followed up every month for six months after the injection. The primary outcome measures were best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) at six months. RESULTS The mean age of the patients included in the study was 64.64 ± 7; there were 58 men (61.7%) and 36 women (38.3%). There was no statistically significant difference between the groups regarding age, stage of retinopathy, and lens status. When CMT, BCVA, and IOP were assessed among the four groups at the end of the sixth month, no statistical difference between the groups was found. There was no need for medical intervention despite the statistically significant increase in IOP at the end of the sixth month compared to the third month in the dexamethasone implanted groups. In contrast to the decrease in CMT, which was statistically significant in all four groups at the end of the sixth month compared to the third month, the increase in BCVA was not statistically significant in any of the four groups at the end of the sixth month. CONCLUSION According to the results of our study, there is no superiority between continuing with existing anti-VEGF or switching to a dexamethasone implant after three doses of anti-VEGF.

Effect of intravitreal dexamethasone implant in treatment-naive and previously-treated patients with diabetic macular edema. Eur J Ophthalmol 2022; 33:11206721221143166.

Abstract
PURPOSE To document the effects of intravitreal dexamethasone implant on retinal microvasculature in patients with diabetic retinopathy complicated by center-involving macular edema. METHODS 35 eyes of 35 patients affected by retinopathy due to type 2 diabetes (15 treatment-naïve and 20 previously treated) were included in this retrospective study with a follow-up of 4 months. Foveal avascular zone (FAZ) area and superficial capillary plexus (SCP) and deep capillary plexus (DCP) densities in the foveal and parafoveal areas were measured by optical coherence tomography angiography (OCTA) at baseline and 2 and 4 months post-injection. Intraocular pressure, morphological and functional parameters were evaluated. RESULTS a significant difference was found in both groups at 2 months after injection in terms of functional (BCVA, p < 0.05) and morphological (CMT, p < 0.05) parameters. During follow-up, FAZ area, SCP, and DCP in the foveal and parafoveal areas did not change significantly. CONCLUSIONS intravitreal dexamethasone implant is effective in the treatment of diabetic center-involving macular edema and was associated with significant improvements in BCVA and CMT at 2 months after injection. After a single dexamethasone implant injection, FAZ area and retinal vascular density does not show significant variations in both naive and non-naive DME patients subgroups.

Efficacy and safety of single-dose dexamethasone implantation for patients with persistent diabetic macular edema: a systematic review and meta-analysis. Graefes Arch Clin Exp Ophthalmol 2021; 260:405-413. [PMID: 34550419 DOI: 10.1007/s00417-021-05369-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 07/15/2021] [Accepted: 08/05/2021] [Indexed: 02/05/2023] Open
Abstract
PURPOSE This meta-analysis was conducted to evaluate the efficacy and safety of single-dose dexamethasone implantation for treating persistent DME (diabetic macular edema) refractory to anti-VEGF (anti-vascular endothelial growth factor) drugs over a period of 6 months. METHODS All related clinical trials were reviewed by searching electronic databases of PubMed, Medline, Web of Science, Cochrane Library, and EMBASE. The primary outcome parameters were best-corrected visual acuity (BCVA) and central macular thickness (CMT). We performed this meta-analysis by using Stata15.0. RESULTS Ten clinical trials involving 362 eyes from 328 patients were eligible in the final analysis. After single-dose dexamethasone implantation, there was a significant improvement in BCVA from baseline to 1, 3, and 6 months with an average increase of - 0.15 logMAR (p < 0.001), - 0.14 logMAR (p < 0.001), and - 0.07 logMAR (p = 0.004), respectively. Further, mean CMT decreased significantly with an average reduction of 249.18 μm (p < 0.001), 217.66 μm (p < 0.001), and 91.56 μm (p < 0.001) at months 1, 3, and 6, respectively. CONCLUSIONS Our results indicate that switching to a dexamethasone implant could achieve significant anatomical and functional improvement among patients with refractory DME. Clinicians should be aware of this treatment option in refractory DME.
