Purpose. This retrospective study aimed to compare the efficacy of intravitreal ranibizumab (IVR) and intravitreal dexamethasone implant (IDI) for pseudophakic vitrectomized eyes with diabetic macular edema (DME) in a single institution. Methods. Pseudophakic vitrectomized eyes with treatment-naïve center-involved DME were enrolled, with one eye in each patient. They were divided into two groups: one group receiving IDI every 3 to 4 months and another group receiving IVR using 3 monthly plus treat-and-extend injections, all with monthly follow-up for 6 months. Switch of intravitreal drugs or deferred macular laser was not allowed. Primary outcome measures included change in central foveal thickness (CFT) in 1 mm by spectral-domain optical coherence tomography and best-corrected visual acuity (BCVA) at Month 6. Results. Twenty-two eyes were included in the IDI group and 26 eyes in the IVR group. The baseline demographics, glycosylated hemoglobin level, intraocular pressure (IOP), BCVA, and CFT did not significantly differ ( p > 0.05 ). Compared to baseline data, CFT decreased and BCVA improved significantly after either IDI or IVR at Month 6 ( p < 0.05 ). Significantly better mean final BCVA (0.38 logMAR vs. 0.62 logMAR, p = 0.04 ), more mean visual gain (−0.30 logMAR vs. −0.15 logMAR, p = 0.02 ), lower mean final CFT (310.9 μm vs. 384.2 μm, p = 0.04 ), and larger mean CFT decrease (−150.0 μm vs. −60.1 μm, p = 0.03 ) were found in the IDI group compared to those in the IVR group. A smaller mean treatment number (2.6 vs. 5.6, p < 0.001 ) and higher rate of postinjection ocular hypertension requiring topical hypotensive agent therapy (27.3% vs. 0%, p = 0.0002 ) were demonstrated in the IDI group than those in the IVR group. Conclusion. We concluded that IDI and IVR can both effectively treat vitrectomized eyes with DME. Dexamethasone implants had significantly better visual/anatomical improvement, smaller treatment number, and higher rate of elevated IOP after injection than IVR in pseudophakic vitrectomized eyes with DME in a 6-month period.

Introduction: In the working age population, Diabetic Macular Edema (DME) is the most common cause of visual loss. Purpose: The present study is aimed to assess the safety and efficacy of intravitreal injection of Ranibizumab (IVR) versus intravitreal Dexamethasone implant (IVD) in patients with DME in a tertiary care centre over 4 months. Methods: This is a comparative, prospective, randomized study that was done on 140 patients with macular edema confirmed on optical coherence tomography (OCT). IVD group received Ozurdex® (Allergan, Inc, Ireland) while the IVR group received Lucentis® (Novartis, Basel, Switzerland) followed up at day-1 and weeks 4, 8, 12,16. Patients were divided into Group A: patients were given 3 doses (monthly) of IVR 0.3 mg in 0.05 ml (n=70). Group B: patients given a single dose of IVD implant 0.7 mg (n=70). Results: The mean number of injections given was 1 Ozurdex® per patient Vs 3 Lucentis® per patient. The maximum reduction in central macular thickness (CMT) with IVD was 167.8 µm and 138.8µm in the 2nd and 3rd months, respectively with IVR. The Mean best-corrected visual acuity (BCVA) in the 4th month was 0.34 logMAR and 0.33 logMAR, in IVD and IVR group, respectively with consistent improvement. Patients with 0-5 letters, 6-10 letters and 10-15 letters, and >15 letters visibility in IVD group were 9.5, 20.6, 4.8, 6.4 %, and 20.4, 18.8, 20.3 20.3 % in IVR groups, respectively. The maximum intraocular pressure (IOP) rise with IVD was found to be 16 mmHg in 2 patients (3.17 %). The patients with IOP rise >10 mmHg was observed in 14/63 patients (22.22 %), the majority of patients indicated a high rise at 2nd month and all returning to baseline by 4th month. No reports of infectious endophthalmitis or new cataracts were detected in either treated groups. Conclusion: Both intravitreal Ranibizumab injection and Dexamethasone implants were found to be safe and effective in lowering CMT and improving BCVA at the 4-month follow up in patients with DME. Since there was no recurrence in CMT in the Dexamethasone implant group, we suggest that early administration before the 4th month may indicate superior efficacy over the ranibizumab injection. Further randomized trials in a large sample size with a longer period follow-up would be performed to justify the obtained results in the present study.

Aim To evaluate the efficacy of intravitreal dexamethasone injections in diabetic macular edema (DME). Methods A 700 μg slow-release intravitreal dexamethasone implant (Ozurdex®) was placed in the vitreal cavity of 17 patients (19 eyes) affected with persistent DME. Best corrected visual acuity (BCVA) was assessed through Early Treatment Diabetic Retinopathy Study (ETDRS). Central macular thickness (CMT) was measured by spectral-domain optical coherence tomography. BCVA and CMT examinations were carried out at baseline (TO) and repeated after three days, one month (T1), three months (T3), four months (T4), and six months (T6) post injection. Results Dexamethasone implant induced an improvement in ETDRS at T1, T3, T4, and T6 post injection. CMT was reduced at T1, T3, and T4, while at T6, CMT values were not statistically different from baseline. No complications were observed during the follow-up. Conclusion Our data suggest that dexamethasone implant is effective in reducing DME symptoms within a six-month frame.
