Purpose: To evaluate the 1-year results of 25-gauge microincision vitrectomy surgery (MIVS25) combined with intraoperative dexamethasone (DEX) implant for persistent diabetic macular edema (DME). Methods: This study enrolled patients who had a history of DME for ≥12 months and underwent MIVS25 and DEX implant injection. Best corrected visual acuity (BCVA) and central retinal thickness (CRT) were assessed postoperatively. Results: Eighteen eyes were included in the analysis. Preoperatively, logMAR BCVA was 0.90 and CRT was 594 µm on average. CRT decreased until the 3-month follow-up visit and tended to increase at 6 months, but stabilized at 12 months with additional treatments in five eyes at 5 months postoperatively. Statistically significant improvement in BCVA was noted 1 month after treatment and at each subsequent follow-up visit (p < 0.001). Conclusion: MIVS25 combined with DEX implant injection might be utilized as an effective and safe alternative treatment for intractable DME.

Abstract Background The purpose of this study was to evaluate the incidence of vitreomacular adhesion (VMA) release after anti-VEGF therapy for the treatment of diabetic macular edema (DME) and to evaluate further changes in outcome. Methods This was a retrospective study that enrolled 66 eyes of 66 patients with DME who presented with VMA diagnosed by spectral-domain optical coherence tomography (OCT) at baseline. VMA was classified as focal (attachment: ≤ 1500 μm) or broad (attachment: > 1500 μm). All patients received at least three monthly intravitreal injections of an anti-VEGF agent. Follow-up visits were performed 1 month after each injection to evaluate the incidence of VMA release. Results The mean patient age was 61.4 years (range: 29 to 78 years), and 72.7 % were male. The mean best-corrected visual acuity was 0.62 logMAR, and the mean central retinal thickness (CRT) was 473 μm at baseline. The mean length of follow-up was 18.5 months, and the mean number of injections was 5.8. The intravitreal drugs used were aflibercept (40.9 %), ranibizumab (37.9 %) and bevacizumab (21.2 %). Forty-seven eyes had broad VMA, and 19 had focal VMA. Twenty-two eyes (33.3 %) developed VMA release following a mean of 5.7 injections (range: 3–13). Sixteen eyes (72.7 %) with focal VMA and 6 eyes (27.3 %) with broad VMA at baseline developed VMA release. Twenty-one eyes that developed VMA release showed an improvement in CRT following VMA release (mean: -106 μm; range: 22 to 289 μm). Conclusions VMA release occurs in approximately 1/3 of patients with DME following anti-VEGF therapy. Most of them show a short-term decrease in CRT.

Purpose: To report visual and anatomical outcomes of chronic/refractory diabetic macular edema (DME) treated with intravitreal fluocinolone acetonide implant. Setting: Retrospective, one arm, multicentric study. Method: Between 2013 and 2018, 27 consecutive eyes of 25 patients with chronic/refractory DME were treated with a fluocinolone acetonide intravitreal implant. Best registered visual acuity (BRVA), central retinal thickness (CRT), and Goldmann tonometry intraocular pressure (IOP) were assessed at 12 and 24 months. The need for IOP lowering treatment as well as top-up therapy during the follow-up were also assessed. Results: The duration of DME prior to treatment in our study was 54 ± 24 months. The baseline mean BRVA of 0.7 ± 0.34 logMAR improved to 0.5 ± 0.3 ( p = 0.01) at 12 months and 0.46 ± 0.3 ( p = 0.04) at 24 months. At 12 months, BRVA improved in 14 eyes (52%), stabilized in 5 eyes (20%), and decreased in 3 eyes (11%). At 24 months, BRVA improved further in 6 eyes (24%), stabilized in 3 eyes (12%), and decreased in 6 eyes (24 %). Mean CRT decreased from 497 ± 176 to 349 ± 186 μm at 12 months ( p = 0.0005) and to 267 ± 104 μm at 24 months ( p = 0.001). Only five eyes required additional treatment for DME and only three eyes required treatment for raised IOP. Discussion: Our results show that the visual and the anatomical improvements achieved by a single injection of a fluocinolone acetonide implant were maintained up to 24 months with minimal additional therapy even in eyes with a long and heavy history; however, IOP monitoring remains essential.

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.

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 evaluate the efficacy of switching from bevacizumab to ranibizumab in patients with diabetic macular edema (DME). Methods This was a retrospective study of patients with DME initially treated with bevacizumab and switched to ranibizumab. Visual acuity (VA) and central retinal thickness (CRT) were retrieved at fixed timepoints prior to and after the switch. Results Forty eyes of 32 patients were included in the study. The difference in VA between any of these fixed timepoints was not statistically significant. A significant gain in VA was found in eyes that lost more than 0.1 logMAR during treatment with the last 3 bevacizumab injections. The mean CRT was significantly lower after the first 3 ranibizumab injections and at the final follow-up (p<0.001), a 67 ± 14 μm and 78 ± 18 μm reduction in thickness, respectively. Conclusions Switching to ranibizumab resulted in a significant decrease in the CRT of eyes with DME, and should be considered when there is a lack of response or deterioration while on bevacizumab injections. A significant gain in VA was observed in a subgroup of eyes that lost more than one line while receiving the last 3 bevacizumab injections prior to the switch.

Abstract 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 was a retrospective study of 125 eyes of 125 treatment naïve DME patients who received anti-VEGF injections at 3 consecutive monthly intervals as the loading phase. Of these 125 eyes, 26 eyes completed the treatment with the TAE regimen for at least 24 months. Among the 26 eyes, 13 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. The changes in the best-corrected visual acuity (BCVA), central retinal thickness (CRT), diabetic retinopathy severity (DRS), and total injection numbers were compared between the two anti-VEGF agents.Results No significant differences were detected in the baseline demographics. At 24 months, the 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=1.29x10 -9 ). 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 ( P=3.55x10 -9 ). No significant differences were detected in the improvements of the BCVA and the CRT in both groups, and the total injection numbers were significant fewer for the IVA group (11.0±1.2) than the IVR group (12.0±1.0). The DRS 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 the BCVA or CRT and injection numbers between 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.

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) injections for the treatment of diabetic macular edema (DME) in eyes with and without previous vitrectomy. Methods: The medical records of 30 eyes (13 vitrectomized, 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 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 hemoglobin A1c (HbA1c) level at baseline were also recorded. Results: Baseline demographics, HbA1c, BCVA, CMT, and TMV values were similar between the vitrectomized and nonvitrectomized groups (p>0.05). The duration between diagnosis of DME and IVR injections was longer in the nonvitrectomized group than in the vitrectomized group (165 years vs. 134 years, respectively; p=0.045). 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). BCVA improved significantly during the 24-month period in both groups. The improvement in BCVA was significant at month 6 in nonvitrectomized eyes, while there was no significant improvement in vitrectomized eyes before month 18. Compared to the baseline values, the decrease in both CMT and TMV was significant in months 6, 12, 18, and 24 in the nonvitrectomized group (p<0.05). In the vitrectomized group both CMT and TMV improved significantly only in months 18 and 24 (p<0.05). Conclusion: IVR treatment for DME is equally effective in both vitrectomized and nonvitrectomized eyes. However, the response to treatment is seen later in vitrectomized eyes compared to nonvitrectomized eyes.

Purpose. To introduce a novel laser photocoagulation (PC) protocol named merged image-guided PC (MIG-PC), which included merging the images of the fundus, optical coherence tomography (OCT) map, and fluorescein angiography (FA). We compared the anatomical and functional results between MIG-PC and FA-guided PC (FG-PC) for the treatment of focal diabetic macular edema (DME). Method. We examined the treatment outcomes in 27 consecutive eyes treated with MIG-PC compared with 28 matched eyes treated with FG-PC. We identified the microaneurysms (MAs) located in the focal edema areas and ablated them using focal PC. Best-corrected visual acuity (BCVA) and retinal thickness (RT) measured using OCT were compared between the groups at baseline and 2, 4, 8, 12, and 24 weeks after treatment. Results. The foveal and perifoveal RT were reduced after treatment in both the groups, and the perifoveal RT in the MIG-PC group was significantly lower than that in the FG-PC group at 4 weeks and thereafter. BCVA in the MIG-PC group was significantly higher than that in the FG-PC group at 12 and 24 weeks. The numbers of laser spots (p=0.0001), additional laser treatments (p=0.0121), and intravitreal injection of ranibizumab (p=0.0012) in the MIG-PC group were significantly lower than those in the FG-PC group (Mann–Whitney test). Conclusion. MIG-PC contributed to the improvement in BCVA and reduction in RT, number of laser shots required, and retreatment rates. Based on our data, MIG-PC can be recommended for the treatment of focal DME. This trial is registered with ID UMIN000030390.

Aims. To investigate the correlations between renal biomarkers and the treatment outcomes of ranibizumab for diabetic macular edema (DME). Methods. This hospital-based study retrospectively enrolled 88 eyes from 67 patients who had received one-year intravitreal ranibizumab treatment for DME. Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) at baseline and during the follow-up period were recorded. BCVA and OCT characteristics at baseline and their changes after ranibizumab treatment were compared between different proteinuria and estimated glomerular filtration rate (eGFR) groups. Results. Of the 88 eyes studied, those with moderately increased proteinuria had a thicker central subfield foveal thickness (CFT) and a higher proportion of intraretinal cysts than those with no proteinuria (P=0.012 and 0.045, respectively) at baseline. After one year of ranibizumab treatment, the reduction in CFT was greater in patients with severely increased proteinuria than those with normal to mildly increased proteinuria (P=0.030). On the other hand, patients with an eGFR <30 tended to have poorer visual improvements than those with normal eGFR (P=0.044). Conclusions. After ranibizumab treatment for DME, patients with severe proteinuria tended to gain better anatomical improvement, while those with poor eGFR tended to have poorer visual improvement.
