Purpose To investigate the adjunct efficacy and safety of vitamin supplements, including resveratrol, in patients with diabetic macular edema (DME) treated with intravitreal anti-vascular endothelial factor (anti-VEGF) agents. Methods Participants in this prospective study were 45 patients with DME, who were treated with either intravitreal anti-VEGF injections (n = 23, Group I) or with combination of intravitreal anti-VEGF injections and vitamin supplements, including resveratrol (n = 22, Group II). All patients underwent visual acuity measurement, slit-lamp examination and spectral domain-optical coherence tomography (SD-OCT) at baseline and monthly after the loading phase of three-monthly anti-VEGF injections, following a PRN protocol. Results There was a statistically significant improvement in visual acuity in both groups at month 12 compared to baseline, although the mean change in visual acuity did not differ between the two groups (p = 0.183). Accordingly, there was a statistically significant decrease in central retinal thickness in both groups at month 12 compared to baseline, while the mean difference in central retinal thickness was significantly greater in the “combination” group. The mean number of intravitreal anti-VEGF injection was less in Group II (6.45 ± 1.12 in Group II vs. 7.39 ± 1.31 in Group I, p = 0.018). Conclusions Vitamin supplements with resveratrol was found to be an effective adjunct to intravitreal anti-VEGF injections in patients with DME, offering better anatomic restoration with less injections at the 12-month follow-up.

Purpose. The aim was to evaluate the efficacy of aflibercept in patients with diabetic macular edema (DME) unresponsive to prior anti-VEGF therapy. Methods. Retrospective review of DME unresponsive to previous anti-VEGF switched to aflibercept with 3 months of follow-up. Changes in best correct visual acuity (BCVA), central retinal thickness (CRT), and frequency of injections were analyzed. The percentage of subjects who had ≥20/40 (logMAR equivalent 0.3) and ≤20/200 (logMAR equivalent 1) was evaluated. Results. A total of 32 eyes from 26 patients were included. Mean age was 65 ± 10 years old. The mean number of previous anti-VEGF injections was 5.34 ± 2.38, and the mean number of aflibercept injections at the end of the study was 2.00 ± 0.00. The CRT at baseline was 501.47 ± 150.51 μm and 367.97 ± 124.61 μm at 3 months of follow-up (P<0.001). The logMAR BCVA at baseline was 0.71 ± 0.36 and 0.65 ± 0.33 at the end of the follow-up (P=0.037). At baseline, 12.5% of patients had ≥20/40 compared with 25% at the end of follow-up. At baseline, 28.13% of patients had 20/200 or inferior vision compared with 15.63% at the end of the follow-up. Conclusions. DME patients unresponsive to previous multiple ranibizumab injections demonstrate a significant anatomical and functional improvement with the switch to aflibercept.

Background: Subthreshold nondamaging retinal laser therapy (NRT) provides a greater safety profile than conventional laser methods, but more data is needed on the efficacy and safety of subthreshold NRT in diabetic macular edema. Purpose: To evaluate the efficacy and safety of NRT for the treatment of clinically significant macular edema (CSME) that is partially responsive or resistant to intravitreal anti-vascular endothelial growth factor (anti-VEGF) treatment. Methods: This was a retrospective case series study. Fifty eyes of 38 diabetic patients with CSME previously treated with at least 6-monthly intravitreal bevacizumab injections with/without intravitreal Ozurdex therapy were evaluated. The patients received 577-nm yellow wavelength laser therapy with PASCAL laser system (Topcon Medical Laser Systems, Santa Clara, CA, USA). Best-corrected visual acuity (BCVA) and central subfield thickness (CST) were evaluated before and 1, 3, 6, 12 and 24 months after laser treatment. Results: Baseline mean CST was 368.06 ± 86.9 µm. The mean CST values at the 1-, 3-, 6-, 12-, and 24-month visits were 336.93 ± 79.8, 352.40 ± 113.5, 336.36 ± 109.3, 325.10 ± 104 µm, and 310.08 ± 84.7 µm, respectively. The mean CST decreased significantly at the first ( p = 0.002) and second year visits ( p < 0.001) when compared with pretreatment values. Although visual acuity was improved at the first year compared with baseline, this difference was not statistically significant ( p = 0.03). There was no significant difference in visual acuities between pretreatment and posttreatment visits. During 24-month follow-up, while 37 eyes were treated with [mean: 5.7 ± 3.4 (1–14)] intravitreal anti-VEGF injections, 3 eyes were administered single-dose intravitreal steroids. Additional intravitreal injections were not required in 10 (20%) eyes. Conclusion: NRT is effective by itself or in combination with anti-VEGF agents in diabetic macular edema that is partially responsive or resistant to previous intravitreal injections. T role in treating this disorder should be assessed in more detail with prospective controlled studies.

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 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.

Aflibercept is the most recently approved vascular endothelial growth factor (anti-VEGF) inhibitor for the management of diabetic macular edema and diabetic retinopathy. The purpose of this article is to review the efficacy and safety of aflibercept in the management of diabetic eye complications and to describe its place in therapy. Anti-VEGF agents have been noted in clinical trials to be superior to laser photocoagulation, the standard therapy ( P < .0001, P ≤ .0085, respectively). Aflibercept has been comparatively studied with other anti-VEGF agents, namely, bevacizumab and ranibizumab, and noted to be equally efficacious and safe in patients with mild visual acuity loss ( P > .50). However, in the treatment of patients with diabetic macular edema having moderate to severe visual acuity loss, aflibercept outperformed the other 2 anti-VEGF agents (aflibercept vs bevacizumab, P < .001; aflibercept vs ranibizumab, P = .003). However, additional studies are needed to fully appreciate the long-term safety and efficacy of aflibercept and the anti-VEGF therapy class.

Összefoglaló. Bevezetés és célkitűzés: A Navilas® 577s mikropulzuslézerrel végzett kezelés biztonságosságának és hatásosságának vizsgálata diabeteses maculaoedemában. Módszer: Retrospektív vizsgálatunkba diabeteses maculaoedema miatt gondozott és legalább 6 hónapos utánkövetéssel rendelkező, korábban Navilas® 577s mikropulzuslézer-kezelésen átesett 28 beteg 46 szemét válogattuk be. Minden szemen optikaikoherencia-tomográfia (OCT) vastagsági térkép navigált, nonkontakt, küszöb alatti mikropulzuslézer-kezelés történt egy alkalommal. A kezelést megelőzően és az azt követő 6. hónapban rögzítettük a látóélesség, a centrális retinavastagság értékeit és az éreredetű endothelialis növekedési faktort (VEGF) gátló injekciók számát. A követési idő végén megvizsgáltuk a szemfenéki képnek a digitális fundusfotográfia és az átmetszeti OCT-képek segítségével észlelhető változásait. Eredmények: A vizsgált szemek közül 30 esetben a lézerkezelést korábbi centrális maculaoedema miatt VEGF-gátló injekciós kezelés előzte meg, míg 16 szem esetében primer lézerkezelés történt. A Navilas® 577s mikropulzuslézer-kezelést követően 6 hónappal sem a látóélesség, sem a centrális maculavastagság nem változott szignifikánsan egyik csoportban sem (p>0,05). Ugyanakkor a korábban injekciós kezelésben részesült szemek esetében a lézerkezelést megelőző 6 hónapban adott injekciók száma az átlagos 2,63 ± 1,18 értékről átlagosan 0,5 ± 0,73 értékre csökkent (p<0,001). A fundusfotókon és az átmetszeti OCT-scaneken a lézerkezelést követően egyetlen szem esetében sem találtunk látható pigmentelváltozásokat vagy hegesedést. Következetetés: Megfigyeléseink szerint a Navilas® 577s mikropulzuslézer-kezelés biztonságos a diabeteses maculaoedemás betegek kezelésében, továbbá a VEGF-gátlóval kezelt szemeken szerepet játszhat az injekciók számának csökkentésében. Orv Hetil. 2020; 161(49): 2078–2085. Summary. Introduction and objective: To assess the safety and efficacy of Navilas® 577s micropulse subthreshold laser in the treatment of non-center involved diabetic macular edema. Method: In this retrospective study, we included 46 eyes of 28 patients with diabetic macular edema, who were treated at least 6 months ago with Navilas® 577s micropulse laser. Laser treatment was navigated by optical coherence tomography (OCT) macular thickness map in subthreshold micropulse mode at one occasion. Data from visual acuity testing, retinal thickness, and the number of anti-vascular endothelial growth factor (VEGF) injections needed 6 months before and after treatment were registered. At the end of the follow-up, digital fundus photography and OCT radial scans were performed to evaluate any possible anatomical changes. Results: 30 eyes had previous anti-VEGF treatment for central macular edema, and in 16 eyes we performed the laser as primary treatment. At the end of the follow-up, no significant visual acuity or central retinal thickness change were observed (p>0.05). On the other hand, in the anti-VEGF pretreated group the number of injections decreased significantly from 2.63 ± 1.18 to 0.5 ± 0.73 (p<0.001). We did not find any pigmentary changes or visible signs of scaring on final fundus photography pictures or OCT radial scans. Conclusion: Navilas® 577s subthreshold microsecond laser proved to be a safe option in the treatment of diabetic macular edema. It can be very useful in anti-VEGF treated eyes by decreasing the number of injections needed. Orv Hetil. 2020; 161(49): 2078–2085.

Purpose. To compare the efficacy of pars plana vitrectomy (PPV) versus intravitreal injection (IVI) of ranibizumab (RBZ) in the treatment of diabetic macular edema (DME) associated with vitreomacular interface abnormalities (VMIA). Methods. The records of patients presenting with DME and VMIA throughout 2016 to 2018 were retrospectively analyzed. The patients were divided into 2 groups: group I received IVIs of RBZ and group II underwent PPV with internal limiting membrane peeling. The main outcome measures were the change in the LogMAR corrected distance visual acuity (CDVA) and central subfield thickness (CSFT) on optical coherence tomography over 6 months. Results. At 6 months, mean CDVA improved by 0.22 ± 0.21 in group I patients p < 0.001 , while in group II, it improved only by 0.09 ± 0.22 p < 0.115 . Fifty-five percent of group I and 60% of group II patients had stable CDVA (within 2 lines from baseline) at 6 months. Significant improvement in vision (gain of 2 or more lines) was seen in 45% and 30%, respectively. Worsening of vision (loss of 2 or more lines) was seen only in 2 patients in group II, but none in group I. The mean CSFT improved significantly in both groups (by 162 µ and 216 µ, respectively; p < 0.001 ). The mean CSFT at 6 months was similar in both groups (354 µ and 311 µ, respectively; p = 0.172 ). Conclusions. Both treatments resulted in anatomical improvement of DME with concurrent VMIA. Visual improvement was more pronounced in the IVI group, although this may have been affected by other confounding factors.

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 evaluate the efficacy and safety of intravitreal implant of dexamethasone (Ozurdex®) in diabetic macular edema (DME). Methods: This was a retrospective multicenter noncomparative study. Seventy-eight patients with DME followed for at least 6 months were included (P1.5 Network). Best-corrected visual acuity (BCVA), central retinal thickness (CRT), intraocular pressure (IOP) and cataract progression were studied at baseline and then at 1, 2, 4 and 6 months. Results: The mean CRT decrease from baseline was 145.2 µm at 6 months. The mean BCVA improvement from baseline was 6.7 at 6 months. An increase in IOP was observed for 11.7% of patients, and all patients were managed by topical treatment. No glaucoma or cataract surgery was necessary, and no endophthalmitis was reported. Conclusions: One injection of Ozurdex has an anatomical and functional effectiveness for the treatment of DME. Side effects were rare and manageable in our practice.

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.
