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.

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.

Objective: To evaluate, in the setting of persistent diabetic macular edema, the impact that continuous fluocinolone acetonide delivery has on treatment burden, visual acuity, central retinal thickness, and intraocular pressure. Materials and methods: A single-center, retrospective, cohort study of patients with persistent diabetic macular edema, previously treated with anti–vascular endothelial growth factor injections, dexamethasone implants, or focal laser, who were subsequently treated with fluocinolone acetonide was conducted. All retinal visits were analyzed prior to fluocinolone acetonide, until the most recent follow-up visit. Primary outcomes were pre– and post–fluocinolone acetonide changes in the best-corrected visual acuity and number of treatments required for diabetic macular edema. Secondary outcomes included changes in the central retinal thickness and intraocular pressure. Results: A total of 19 eyes with persistent diabetic macular edema were included and followed for a mean (SD) of 399.3 (222.9) days. Post–fluocinolone acetonide, the mean best-corrected visual acuity improved by 0.4 ETDRS letters for all eyes ( p = 0.895) and the central retinal thickness decreased by 34.2 µm ( p = 0.077). After fluocinolone acetonide, the number of treatments decreased from an average of one treatment every 2.7 months to one every 6 months ( p = 0.009). Furthermore, post–fluocinolone acetonide, 10/19 eyes (52.6%) did not require additional treatment due to a dry macula, and those who did experienced a non-statistically significant reduction of treatments, from one every 2.6 months pre–fluocinolone acetonide, to one every 2.8 months post–fluocinolone acetonide ( p = 0.622). Conclusions: In the setting of persistent diabetic macular edema, fluocinolone acetonide significantly reduces the therapeutic burden, while maintaining best-corrected visual acuity and improving the central retinal thickness. In patient-centered discussions, judiciously employing fluocinolone acetonide should be performed to mitigate this therapeutic burden for patients.

Despite the vitrectomy performed for diabetic macular edema (DME), some patients still have symptoms of the disease due to overproduction of VEGF by the ischemic retina, which requires regular administration of an antiangiogenic drug. Studies of the pharmacokinetics of antiangiogenic drugs after vitrectomy in humans have not been carried out. Data from the DRCR.net (Post-Hawk Protocol I) study and real-life clinical practice studies show similar results for anti-VEGF DMO therapy in vitreous eyes and after vitrectomy (2, 7). Purpose. To assess the effectiveness of antiangiogenic therapy with aflibercept for DMO in avitreal eyes in real clinical practice. Methods. The initial and after vitrectomy best corrected visual acuity (BCVA) and central retinal thickness (CRT) were determined according to OCT data, then these parameters were monitored by 1, 3, 6 and 12 months after the start of antiangiogenic therapy with aflibercept. 14 patients (14 eyes) with persistent DME underwent vitrectomy with removal of the internal limiting membrane, in 5 of them the epiretinal fibrosis was removed and 3 of them with a traction retinal detachment that was also removed with air tamponade. Results. Aflibercept intravitreal injections were started with 5 loading doses by 1-11 months after vitrectomy. On average, after 12 months, patients received 7.2 injections, while there was no need for laser surgery of the macular zone. By the end of the study, the CRT decreased by 255 ±86 µm, the BCVA was 0.35 ± 0.2 in comparison with the initial 0.07±0.03 (on a decimal scale). Conclusions. The effectiveness of the anti-VEGF therapy with aflibercept for DME in avitreal eyes was confirmed by an increase in functional (BCVA) and normalization of morphological (CRT on OCT) parameters after the first injections during the period of loading doses. Previous vitrectomies in patients with DMO do not affect the long-term favorable clinical outcomes of anti-VEGF therapy with aflibercept. Key words: vitrectomy, diabetic macular edema, aflibercept, anti-VEGF, OCT, best corrected visual acuity, central retinal thickness.

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.

AbstractThis study aimed to assess detection rate of telangiectatic capillaries (TelCaps) with infrared reflectance (IR) and optical coherence tomography (OCT) images and to evaluate the clinical efficacy of IR image-guided focal laser photocoagulation of TelCaps in persistent diabetic macular edema (DME). This retrospective case series included 28 eyes of 28 patients with TelCap and persistent DME refractory to intravitreal anti-vascular endothelial growth factor or corticosteroids. The presence of TelCaps was confirmed using IR and OCT images. All patients were followed up for more than 12 months after direct focal laser photocoagulation of the TelCaps. The TelCap closure rate, changes in best-corrected visual acuity, and central subfield thickness were analyzed. On IR imaging, TelCap appeared as a characteristic hyperreflectivity within a hyporeflective spherical lesion in 85.7% of the eyes. After focal laser photocoagulation, the TelCap closure rate was 57.1% at 3 months and 71.4% at 12 months. A significant improvement in visual acuity and reduction in central subfield thickness were observed at three and 12 months after focal laser photocoagulation (all p < 0.05). The characteristic hyperreflectivity within hyporeflective lesions on the IR image in conjunction with OCT helps identify the TelCap. Our results suggest that IR imaging and OCT-guided focal laser photocoagulation of TelCaps can improve functional and anatomical outcomes in persistent DME.

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 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.

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.
