The purpose of this study was to compare the efficacies of one initial intravitreal injection of aflibercept followed by a pro re nata (PRN; 1+PRN) regimen to those of three consecutive monthly injections followed by the PRN (3+PRN) regimen for diabetic macular edema (DME) with practical protocols. The medical records of 95 eyes of 71 cases that were diagnosed with DME and had received intravitreal aflibercept (IVA) injections were reviewed. Fifty-seven eyes had received IVA with the 1+PRN regimen, and 38 eyes had received IVA with the 3+PRN regimen. The best-corrected visual acuity (BCVA) and the central macular thickness (CMT) were measured at the baseline and at 1, 3, 6, and 12 months after the IVA. The mean number of injections of the 1+PRN group was 2.9 ± 1.7 , which was significantly fewer than that of the 3+PRN group at 4.6 ± 1.4 ( P < 0.001 ). The change of the mean BCVA before and after the IVA at 12 months of the 3+PRN group was − 0.14 ± 0.17 logMAR units which was significantly better than that of the 1+PRN group of − 0.045 ± 0.25 logMAR units ( P = 0.02 ). The change of the CMT before and after the IVA at 6 months of the 3+PRN group was − 141.3 ± 152.4   μ m which was significantly more than that of the 1+PRN group at − 86.1 ± 117.8   μ m ( P = 0.013 ). Although the mean number of injections was more than that in the 1+PRN regimen, the 3+PRN regimen had better visual outcomes at 12 months. In a practical protocol, we recommend the 3+PRN regimen for patients with DME (IRB#3541).

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).

Purpose. To compare the visual and anatomic outcomes in patients with persistent diabetic macular edema (DME) who switched from ranibizumab to aflibercept with those who continued with previous ranibizumab therapy. Methods. In this retrospective comparative study, medical records of consecutive patients with center-involved DME ≥ 350 μm who had at least three recent consecutive monthly ranibizumab injections followed by as-needed therapy with either aflibercept or ranibizumab were reviewed. Data were collected at presentation (preinjection), at the intermediary visit, and at the last visit (at the end of the follow-up period). Results. Forty-three eyes of 43 patients were divided into two groups: the switch group (n=20) and the ranibizumab group (n=23). Though no significant improvement was found in the mean BCVA from the intermediary visit to the last visit, there was a difference in the mean CMT in the switch group and the ranibizumab group (p<0.001 and p=0.03, resp.). The mean CMT decreased after the intermediary visit by 188.6 ± 120.5 μm in the switch group and by 60.3 ± 117.1 μm in the ranibizumab group (p=0.003). Conclusions. Both aflibercept and ranibizumab decreased CMT in patients with persistent DME who showed a poor response to ranibizumab injections. However, switching to aflibercept provided only morphologic improvement.

AIM: To evaluate the two-year outcomes of patients treated for diabetic macular edema (DME) with intravitreal Conbercept (IVC). METHODS: The clinical data of 30 DME patients (36 eyes) were retrospectively reviewed. The patients were treated with IVC for 3mo. Additional IVC was given at subsequent monthly visits, if needed (3+PRN). The patients were followed up for 24mo. RESULTS: The best-corrected visual acuity (BCVA) at 24mo significantly increased (66.7±15.3 letters) in comparison with the baseline (54.4±15.4 letters, P<0.0001). The mean improvement in BCVA was 11.0±2.9 letters. At 24mo, 44.1% of the eyes surveyed gained ≥15 letters, 52.9% of the eyes gained ≥10 letters, and 70.6% of the eyes gained ≥5 letters. No vision loss was noted in 96.8% of the eyes, and 5.9% of the eyes lost ≥5 letters, but ≤10 letters. The central retinal thickness (CRT) at 24mo was significantly reduced (277.1±122.9 μm) in comparison with the baseline (510.9±186.1 μm, P<0.0001). At 24mo, 43.3% of the patients had a CRT ≤250 μm. The mean number of injections over 24mo was 10.6±2.0. No severe eye or systemic adverse events related to either the drug or injection were noted. CONCLUSION: IVC is safe and effective for the treatment of DME.

Abstract Background: Calcium dobesilate (CaD) had been used in the treatment of diabetic retinopathy (DR) due to its potential in protecting against retinal vascular damage. However, it did not reduce the risk of development of diabetic macular edema (DME). The aim of this study was to investigate the effect of CaD plus intravitreal ranibizumab in the treatment of DME.Methods: This retrospective, observational, consecutive case control study enrolled patients newly diagnosed with DME who received intravitreal ranibizumab (IVR) administration with 3-monthly loading dose injection followed by pro re nata (3+PRN) regimen with or without CaD orally daily for at least 12-month follow-up. Medical records and optical coherence tomography (OCT) results were reviewed and compared at baseline and at 3, 6, and 12 months after injection.Results: A total of 102 eyes from 102 patients were enrolled in this study. Fifty-four patients received IVR combined with CaD orally (IVR+CaD group), while forty-eight patients received IVR solely (IVR group). No statistically significant differences were found in the general condition of patients between the two groups at baseline (P > 0.05). At every follow-up, 3, 6 and 12 months after injection, the best corrected visual acuity (BCVA) improved and the central macular thickness (CMT) decreased in both groups when compared with those at baseline (P < 0.05), while there were no significant differences in BCVA improvement and CMT reduction between the two groups (P > 0.05). The mean number of ranibizumab injections in R+C group was significantly lower than that in R group (5.4 ± 1.1 injections versus 6.7 ± 1.6 injections, P<0.05) within 1-year treatment. No adverse events were found in neither groups.Conclusions: Adding oral CaD to intravitreal ranibizumab was demonstrated to have similar effectiveness and safety for improving visual function and restoring the anatomy of the retina in macular with fewer injections in DME patients.

Abstract Background To compare the effectiveness of intravitreal ranibizumab (IVR) and aflibercept (IVA) with the Treat-and-Extend (TAE) regimen for diabetic macular edema (DME).Patients and methods Thirteen eyes received an intravitreal injection of 0.5 mg ranibizumab (mean age, 70.9±6.0 years) and 13 eyes received 2 mg aflibercept (65.9±8.6 years). After 3 consecutive monthly injections, they received additional injections with the TAE regimen. The changes in the best-corrected visual acuity (BCVA), CRT, and total number of injections were compared.Results No significant differences were detected in the baseline demographics. The BCVA was significantly improved for both groups; 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 at 24 months ( P <0.01). The 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 at 24 months ( P <0.01). No significant differences were detected in the improvements of the BCVA and reduction in the CRT between them. The total number injections were significant fewer for the IVA group (11.0±1.2) than the IVR group (12.0±1.0) at 24 months ( P =0.02).Conclusion The results showed that the TAE regimen was effective. The IVA group required fewer injections to attain the same improvements.

The purpose of this study was to determine the efficacy of one-year treatment of diabetic macular edema (DME) with intravitreal aflibercept (IVA) injections on a practical protocol. The medical records of 51 eyes of 43 patients who were diagnosed with DME and had received IVA treatments were reviewed. The best-corrected visual acuity (BCVA) and the central macular thickness (CMT) were measured at the baseline and at 1, 3, 6, and 12 months after the IVA. The mean number of IVA injections was 3.8±2.4. The mean BCVA was significantly better and the CMT was thinner after the IVA at all follow-up times (P<0.05). The BCVA was better in eyes with a serous retinal detachment (SRD) than without a SRD (P<0.01). There was a significant correlation between the photoreceptor outer segment (PROS) length and BCVA at the baseline and at 12 months after the IVA (P<0.05). A fewer number of IVA injections significantly improved the BCVA and the CMT in eyes with DME after one-year treatment. IVA was more effective in the SRD+ group than in the SRD− group. The PROS length may be a predictive marker for visual outcomes after one-year treatment with IVA for DME (IRB#2272).

The aim of this study was to compare the effectiveness of intravitreal ranibizumab (IVR) injections for the treatment of diabetic macular edema (DME) in eyes with and without previous vitrectomy. The medical records of 28 eyes (11 vitrectomized and 17 nonvitrectomized) of 28 patients (mean age, 59.0 ± 9.6 years; male to female ratio 1 : 1) who were diagnosed with DME and had received IVR treatment were reviewed retrospectively. The indications of vitrectomy in 11 vitrectomized eyes were intravitreal hemorrhage (n = 8) and epiretinal membrane (n = 3). The best-corrected visual acuity (BCVA), central macular thickness (CMT), and total macular volume (TMV) were measured at baseline and at months 6, 12, 18, and 24 of the follow-up. The number of IVR injections, the duration between diagnosis of DME and IVR injection, and the hemoglobin A1c (HbA1c) level at baseline were also recorded. Baseline demographics, HbA1c, BCVA, CMT, and TMV values were similar between two groups (p>0.05). The duration between diagnosis of DME and IVR injections was similar in both groups (16 ± 5 months vs. 13 ± 4 months, respectively; p=0.11). IVR injection was performed 6.3 times in vitrectomized eyes and 6.1 times in nonvitrectomized eyes during the 24-month period (p>0.05). The mean BCVA improved significantly during the 24-month period in both groups. The improvements in BCVA, in CMT, and in TMV were more significant at month 6 (p=0.036) group, at month 12 (p=0.013), at month 12 (p=0.021), and month 24 (p=0.021) in nonvitrectomized eyes, respectively, while there was no difference in improvements of BCVA, CMT, and TMV in vitrectomized group at each visit. Treatment effected by time in terms of BCVA, CMT, and TMV values in all groups (p=0.0004, p<0.0001, p<0.0001, respectively), not by time-group interaction and group (all p values >0.05). In conclusion, IVR treatment for DME is equally effective in both groups. However, the response to treatment is seen earlier in nonvitrectomized eyes compared to vitrectomized eyes.

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.

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.

Purpose: To assess the efficacy and safety of a modified treat-and-extend (mTAE) regimen of aflibercept for macular edema (ME) due to branch retinal vein occlusion (BRVO). Methods: This prospective multicentre intervention study evaluated 50 eyes of 50 patients enrolled from October 2016 to September 2017. The patients received intravitreal aflibercept (IVA) injections on an mTAE regimen for a total of 12 months. The main outcome measures were best-corrected visual acuity (BCVA) and central subfield thickness (CST) at 12 months. Results: The baseline BCVA and CST were 0.33 (0.27) and 488 (171) µm (mean (standard deviation)), respectively. The BCVA and CST were significantly improved at month 12 (0.067 (0.19) LogMAR and 295 (110) µm; both p < 0.0001, paired t-test). The mean number of clinic visits and IVA injections was 6.71 (1.41) and 4.26 (0.71), respectively. The time to first recurrence from the first injection was most frequently 3 months. Conclusion: The mTAE regimen of IVA injections for ME due to BRVO effectively improved BCVA and reduced CST, and thus might be an effective therapy to reduce the number of injections and visits.
