Background: To compare the effectiveness of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) performed with the treat-and-extend (TAE) regimen on eyes with diabetic macular edema (DME). Patients and methods: This is a retrospective study of 125 eyes of 125 treatment-naïve DME patients who received anti-VEGF injections at three consecutive monthly intervals as the loading phase. The changes in the best-corrected visual acuity (BCVA), central retinal thickness (CRT), diabetic retinopathy severity scale (DRSS), and total injection numbers were compared between the two anti-VEGF agents. Results: Among 125 eyes, 26 eyes completed the treatment with the TAE regimen for 24 months (20.8%). Thirteen eyes of 13 patients (mean age, 70.9 ± 6.0 years) received intravitreal injections of 0.5 mg ranibizumab, and 13 eyes of 13 patients (65.9 ± 8.6 years) received 2 mg aflibercept. No significant differences were detected in the baseline demographics. At 24 months, BCVA was significantly improved in both groups; from 0.31 ± 0.19 to 0.10 ± 0.12 logMAR units for IVR and 0.41 ± 0.19 to 0.16 ± 0.28 logMAR units for IVA (p = 1.29 × 10−9). CRT was significantly reduced in both groups; 440.9 ± 69.3 to 307.5 ± 66.4 μm for IVR and 473.9 ± 71.5 to 317.8 ± 71.2 μm for IVA (p = 3.55 × 10−9). No significant differences were detected in the improvements of BCVA, CRT in both groups, and the total injection numbers for 24 months (11.0 ± 1.2 for the IVA group and 12.0 ± 1.0 the IVR group). DRSS was significantly improved in both groups (p = 0.0004 for IVR and p = 0.009 for IVA). Conclusion: No significant differences were detected in the improvements of BCVA or CRT and injection numbers between the IVR and IVA groups treated with the TAE regimen. These results indicate that the results of the treatment with both agents with the TAE regimen were equally effective, but only 20.8% of patients completed 24 months of continuous treatment with the TAE regimen. Synopsis: There are no significant differences regarding effectiveness between the IVR and IVA groups treated with the TAE regimen for DME eyes.

Purpose: To compare the efficacy of ranibizumab and aflibercept in the treatment of diabetic macular edema associated with subfoveal retinal detachment. Methods: This is a retrospective, comparative study. The treatment-naïve diabetic macular edema patients who had diabetic macular edema associated with subfoveal retinal detachment and underwent intravitreal aflibercept or intravitreal ranibizumab treatment were included. The patients were treated on a pro re nata treatment regimen after a loading dose of 3-monthly injections and the follow-up time was 12 months. The primary outcome measure of this study was the presence of subfoveal retinal detachment after treatment at different time points. The secondary outcome measures were the change in best corrected visual acuity and central retinal thickness. Results: A total of 46 eyes of 46 patients were included. The aflibercept group consisted of 20 and the ranibizumab group consisted of 26 eyes. During the follow-up period of 12 months, subfoveal retinal detachment was completely resolved in 75% versus 57.7% of the eyes at month 3 (p = 0.2), 90% versus 76.9% at month 6 (p = 0.2), 90% versus 65.4% at month 9 (p = 0.05), and 100% versus 80.8% at month 12 (p = 0.03) in the intravitreal aflibercept versus intravitreal ranibizumab groups. The change in best corrected visual acuity was not statistically different between the groups at months 3, 6, 9, and 12, respectively (p > 0.05 for all). Conclusion: Both intravitreal aflibercept and intravitreal ranibizumab were effective in regards to anatomical and functional outcomes of diabetic macular edema patients associated with subfoveal retinal detachment. Interestingly, intravitreal aflibercept seemed more effective than intravitreal ranibizumab in the resolution of subfoveal retinal detachment at month 12.

Abstract Purpose To report the effectiveness of intravitreal aflibercept (IVT-AFL) treatment for diabetic macular edema (DME) in French clinical practice. Methods APOLLON (NCT02924311) was a prospective, observational cohort study of patients with DME. Effectiveness was evaluated by change from baseline in best-corrected visual acuity (BCVA) at 12 months in treatment-naïve patients (i.e., had not received any anti-vascular endothelial growth factor [anti-VEGF] agent, laser, or steroid at IVT-AFL treatment start) and previously treated patients (i.e., previously treated with anti-VEGF agents other than IVT-AFL, laser, or steroids at IVT-AFL treatment start). Secondary endpoints included change in central retinal thickness (CRT) over 12 months, frequency of injections, and proportion of patients with safety events. Results Of the 147 patients followed for at least 12 months and included in the effectiveness analysis, 52.4% (n = 77) were treatment-naïve and 47.6% (n = 70) were previously treated. Mean (standard deviation [SD]) BCVA score at baseline was 62.7 (14.3) Early Treatment Diabetic Retinopathy Study (ETDRS) letters in treatment-naïve patients and 60.0 (13.7) ETDRS letters in previously treated patients. At month 12, mean (SD) change in BCVA was + 7.8 (12.3) letters in treatment-naïve patients and + 5.0 (11.3) letters in previously treated patients. Mean CRT decreased in both patient cohorts. The mean (SD) number of IVT-AFL injections at month 12 was 7.6 (2.5) for treatment-naïve patients and 7.6 (2.3) for previously treated patients. Of 388 patients included in the safety analysis, ocular treatment-emergent adverse events occurred in 54.1% (n = 210) of patients. Conclusion IVT-AFL treatment was associated with improvements in functional and anatomic outcomes in both treatment-naïve and previously treated patients with DME in France.

We compared the efficacy of intravitreal aflibercept (IVA) to intravitreal ranibizumab (IVR) injections in eyes with diabetic macular edema (DME). The medical records of 49 eyes of 36 patients who were diagnosed with DME and had received IVR and 46 eyes of 40 patients who had received IVA treatment were reviewed. The central macular thickness (CMT) and best-corrected visual acuity (BCVA) were measured at the baseline and at 1, 3, and 6 months after the IVR or IVA. The mean number of injections of IVR was 2.6±1.1 and of IVA was 2.7±1.4. At 6 months, the CMT was significantly thinner than the baseline after IVR and after IVA. The mean BCVA was significantly better than the baseline after IVR only at 1 and 3 months and after IVA at 1 and 6 months. The BCVA of eyes with serous retinal detachment (SRD) was significantly better at 1 month after the IVR and at 1 month and 6 months after the IVA. The BCVAs improved more significantly in the SRD+ group than in the SRD− group. The effects of IVA persist longer than that of IVR. The effectiveness of both IVR and IVA was not dependent on the presence of SRD (IRB#2107).

Abstract Purpose: To investigate longer-term functional and morphological outcomes and their predictors in diabetic macular edema (DME) following a treat and extend regimen (TER) without loading dose under ranibizumab. Methods: Patient data were reviewed and analyzed retrospectively over a period of 24 months after initiation of TER. Best-corrected visual acuity (BCVA), treatment frequency as well as quantitative and qualitative Spectral-domain Optical Coherence Tomography parameters were assessed. Results: 118 eyes of 87 patients were included. A mean of 9.742.13 injections in the first and 7.632.29 in the second year were applied. There were significant gains of BCVA and reductions in central retinal thickness from baseline to month 12 and 24 (all p<0.001). Percentage of eyes with an intact inner-/outer segment (IS/OS) junction increased from 15.3% at baseline to 42.1% at month 24 (p<0.001). An intact IS/OS junction at baseline increased the probability of having a dry retina after 12 months by 79.3% (p=0.017) and after 24 months by 88.1% (p=0.040). Less IS/OS disruption at baseline predicted longer maximum recurrence-free treatment intervals at 2 years (r=-0.345, p<0.001) and better BCVA at one year (r=-0.347, p<0.001). Baseline bigger intraretinal cysts were associated with more IS/OS disruption at 24 months (r=0.305, p=0.007). Younger age and lower BCVA at baseline were predictive for a higher BCVA gain at 24 months (p=0.046, p<0.001). Conclusion: Ranibizumab applied in a TER without loading dose in DME significantly improves visual acuity and retinal anatomical structure throughout two years. The evaluated predictors might help to guide routine clinical treatment in DME.

Purpose: To compare the effectiveness of intravitreal ranibizumab (IVR) for diabetic macular edema (DME) between eyes with and without previous vitrectomy. Procedures: We prospectively assessed the best-corrected visual acuity (BCVA) and central macular thickness (CMT) after IVR for 6 months. Results: There were no significant differences in the baseline BCVA and CMT between both groups. In the nonvitrectomized group (n = 15), the mean changes of BCVA and CMT from baseline to month 6 were significant (p < 0.01). In the vitrectomized group (n = 10), the improvement appeared to be slower, and the mean BCVA improvement was not significant (p = 0.5), although the mean CMT decrease was significant (p < 0.05). There were no significant differences in the mean changes of BCVA and CMT between both groups at 6 months. Conclusions: The difference in the effectiveness of IVR between both groups was not significant. IVR can be a treatment option even for vitrectomized DME eyes.
