Purpose. Inflammation plays a key role in the pathogenesis of diabetic macular edema (DME), and intravitreal corticosteroids are among the recommended therapies. The goal of this retrospective analysis was to describe outcomes with dexamethasone intravitreal implant (DEX implant) in real life. Methods. Medical digital records of DME patients treated with DEX implant and followed up for 3 years were analyzed. Treatment with DEX implant was started either as first-line therapy in pseudophakic patients and in patients with cardiovascular comorbidities or as second-line therapy in patients refractory to the inhibitor of the vascular endothelial growth factor (anti-VEGF) therapy. Analyzed outcomes included central macular thickness (CMT) and best-corrected visual acuity (BCVA). Mean number of implant injections per patient and mean duration of the interval between injections were also estimated. Results. Seventy-five patients (mean age 65.7 (±12.3) years; 53 phakic and 22 pseudophakic) with DME were included. Overall, 84 eyes were treated. Mean CMT improved from 380.1 (±100.3) µm at baseline to 306.8 (±77.0) µm at 36 months (p=0.0003). Mean BCVA improved for up to 6 months (p=0.08) and then started to decrease reaching values lower than baseline after 24 months. In pseudophakic patients, BCVA improvements were more pronounced and sustained up to 36 months (p=0.6). Over 36 months, each patient received on average 2.4 (±1.6) intravitreal injections of DEX implant. The time interval between consecutive injections was included between 180 and 240 days. No unexpected safety issues were reported. Conclusions. With fewer than 3 injections per patient over a 3-year period, DEX implant was able to improve anatomic outcomes in DME patients. Only pseudophakic eyes showed also a long lasting functional benefit at 36 months.

AIM: To investigate the safety and efficacy of intravitreal dexamethasone implants (Ozurdex®/DEX) in patients with diabetic macular edema (DME) either naïve or non-naïve to anti-VEGF therapies who switched to DEX implant independent of response to anti-vascular endothelial growth factors (anti-VEGFs). METHODS: This was an audit retrospective review of medical records of patients with DME who switched to the DEX intravitreal implant. Patients were divided into 2 groups: patients naïve to antiangiogenic therapy and patients who were previously treated with anti-VEGFs. Data regarding demographics, changes in mean best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) was collected over 6mo. The demographic data mean changes in BCVA, CMT, and IOP were compared. Six-month follow-up data of 47 patients (57 eyes), who either switched to DEX implant irrespective of response to previous treatments or were treatment naïve before receiving DEX implant, was collected. RESULTS: Improvement in mean BCVA was observed from 1-4mo after injection with a decreased effect at month 6 as expected, with better outcomes in naïve compared to non-naïve patients. A statistically relevant decrease in mean CMT was observed during the follow-up period. An increase in mean IOP was observed in the first 2mo after DEX therapy. The mean number of injections of the overall population during the 6mo was 1.3. A subgroup analysis showed no relevant difference between phakic versus pseudophakic patients relative to measured outcomes. There was no cataract progression during the follow-up period and no adverse events reported. CONCLUSION: This real-life setting study shows that intravitreal DEX implant is effective and safe. The timings of greater therapeutic impact are concordant with previous studies and suggest that earlier treatment with corticosteroids may have an additional benefit in naïve patients.

Intravitreal Implant

Observational studies are needed to confirm the long-term efficacy and safety of Ozurdex® intravitreal implant in real life. Among 29 patients with persistent diabetic macular edema (DME), of whom 14 (48%) patients did not have any previous treatments and 22 (76%) any previous antivascular endothelial growth factor (anti-VEGF) injections, significant visual acuity (VA) improvement was observed with a mean gain of 13.8 letters at month 6 (p < 0.0001), 12.7 letters at month 12 (p = 0.0032) and 16.5 letters at month 18 (p = 0.0313). During the follow-up, a total of 17 (59%) patients had a VA improvement of ≥15 letters. Significant central macular thickness decrease was observed with a mean reduction of 159.07 μm at month 6 (p < 0.0001), 181.8 μm at month 12 (p < 0.0001) and 236.17 μm at month 18 (p = 0.0313). No serious adverse events were reported. With a good efficacy and safety, manageable adverse events and an injection rate much lower compared to that of anti-VEGF, this study confirms the use of Ozurdex® for the treatment of persistent DME.

Purpose: To evaluate the early effects of dexamethasone (DEX) intravitreal implants in patients with diabetic macular edema (DME). Methods: This was a prospective, single-arm, interventional clinical series. Eighteen patients (18 eyes) with chronic/recalcitrant or naive DME were included. Patients underwent single DEX intravitreal implant. Clinical assessments, including ophthalmologic examination, central retinal thickness (CRT) measurement by spectral-domain optical coherence tomography (SD-OCT) scan, best-corrected visual acuity (BCVA), and intraocular pressure (IOP) were carried out at baseline, 1-3 hours, and then 3, 7, and 30 days after treatment. The main outcome was change in CRT on SD-OCT, while secondary outcome measures included visual acuity (VA) and changes in IOP following implant. Results: Mean CRT significantly decreased from 565 ± 171 µm at baseline to 310 ± 89 µm at end of follow-up (p<0.001), with reduction becoming evident 1-3 hours after injection. Mean BCVA also significantly improved 7 days and 30 days after treatment up to 0.14 logMAR (p<0.05). All patients had a controlled IOP after the injection with only 1/18 eyes having a transient increase in IOP during follow-up. Conclusions: This is the first study showing very early effects of DEX implants on CRT reduction and VA improvement in DME.
