Abstract
PURPOSE OF REVIEW The increasing prevalence of diabetic macular edema (DME) necessitates an updated review of treatment modalities. While the shift from laser to anti-vascular endothelial growth factor (anti-VEGF) therapy has transformed patient outcomes, benefits of these agents are not fully realized in real-world implementation relative to the setting of controlled clinical trials. This review outlines the evolution of intravitreal anti-VEGF treatment extension protocols for DME that reflect efforts to address treatment adherence challenges while optimizing visual outcomes. RECENT FINDINGS Recent studies highlight the efficacy of extended-interval dosing with anti-VEGF agents in managing DME. Trials such as RISE/RIDE, VISTA/VIVID, and LUCIDATE have established the foundation of these regimens by demonstrating sustained visual gains with continuous treatment. However, newer trials including PROTOCOL T, KESTREL/KITE, YOSEMITE/RHINE, and PHOTON have furthered this concept, revealing that less frequent dosing of various anti-VEGF agents can maintain similar visual acuity and anatomical outcomes to traditional monthly injections. SUMMARY The reviewed findings suggest a paradigm shift in DME treatment toward less frequent anti-VEGF injections. This has significant implications for clinical practice, potentially leading to greater adherence to treatment regimens and sustained visual function in patients, while minimizing treatment burden and healthcare costs. Further investigation into the long-term effects of extended dosing intervals is required.

Abstract
PURPOSE The aim of this report is to describe the resolution of refractory cystoid macular edema (CME) associated to retinitis pigmentosa (RP) with IV tocilizumab in three patients. METHODS Retrospective study of a series of consecutive cases of patients treated with off-label IV tocilizumab (anti IL6) for CME refractory to acetazolamide 250 mg for 3 months. Patients were diagnosed with RP by fundus appearance, electrophysiology, visual fields, and genetic testing. A complete ophthalmic examination including spectral-domain optical coherence tomography was performed. RESULTS Three patients with RP and CME refractory to acetazolamide 250 mg for 3 months were treated with monthly IV tocilizumab for at least six months.All patients resolved CME and improved visual acuity after the third month of IV tocilizumab, resolving systemic and ocular adverse events related to previous treatments for CME. Tocilizumab was well tolerated with no other adverse events. DISCUSSION CME causes visual impairment in RP, but current treatments are usually deficient. Tocilizumab has been successfully used as treatment for refractory CME in uveitis, retinal dystrophies, and autoimmune retinopathies. This article reports, for the first time, the long-term resolution of refractory CME in RP with IV tocilizumab.

Abstract
The aim of the study was to determine the efficacy and safety of combined anti-VEGF and steroid therapy in treatment refractory DME patients. We conducted a systematic review and meta-analysis of peer-reviewed articles reporting on visual, anatomical and adverse outcomes to compare the efficacy and safety of combined intravitreal anti-VEGF/steroids versus anti-VEGF monotherapy for refractory DME. Seven studies (4 RCTs and 3 observational studies) reporting on 452 eyes were included. Our systematic review showed that combination therapy is significantly more effective for anatomical outcomes in the treatment of resistant DME compared to anti-VEGF monotherapy in six studies. Two studies found that addition of intravitreal steroids promoted faster visual improvement, but not significantly better final visual outcomes compared to anti-VEGF monotherapy. Combination therapy was associated with a higher incidence of IOP-related adverse events (RR = 0.10, 95% CI = [0.02, 0.42], p = 0.002) and cataract-related adverse events (RR = 0.10, 95% CI = [0.01, 0.71], p = 0.02). Our systematic review and meta-analysis of seven studies and 452 eyes revealed that combination therapy of anti-VEGF and steroid intravitreal drugs in the management of treatment refractory DME resulted in superior anatomical outcomes in all but one study. Combination therapy led to superior short-term visual outcomes in two studies, while others reported no difference between treatment groups. Meta-analysis revealed that combination therapy was associated with more adverse events. Future research should provide guidance on the standard definitions for treatment resistance and therapeutic alternatives for DME patients with sub-optimal response to anti-VEGF treatment.

Abstract
PURPOSE To compare within-subject efficacy and safety of intravitreal dexamethasone implant and topical carbonic anhydrase inhibitors in the treatment of retinitis pigmentosa-related cystoid macular edema. METHODS Patients with bilateral retinitis pigmentosa-related cystoid macular edema were treated with intravitreal dexamethasone implant in one eye and topical carbonic anhydrase inhibitors in the contralateral eye. The primary endpoint was a change in central macular thickness. Secondary endpoints were changes in best-corrected visual acuity and microperimetric central retinal sensitivity. Intraocular pressure and other ocular complications were evaluated for safety assessment. RESULTS Nine patients were recruited for this 12-month follow-up study. Central macular thickness was significantly lower in intravitreal dexamethasone implant-treated eyes than in topical carbonic anhydrase inhibitors-treated eyes at Months 1 and 7, whereas mean best-corrected visual acuity was better in eyes treated with topical carbonic anhydrase inhibitors at Month 12 (borderline significant P = 0.0510). There was no difference in microperimetric sensitivity between the two treatments. Three patients developed ocular hypertension after intravitreal dexamethasone implant. Intravitreal dexamethasone implant showed an effect on the contralateral eye in five of nine patients. CONCLUSION Intravitreal dexamethasone implant was more effective than topical carbonic anhydrase inhibitors in reducing retinitis pigmentosa-related cystoid macular edema 1 month after treatment. Corticosteroids can play a key role in the management of retinitis pigmentosa-related cystoid macular edema; however, their routes, timing, and modes of administration should be further explored.

Abstract
PURPOSE To describe two cases of severe peripapillary pachychoroid syndrome successfully managed with monthly intravitreal aflibercept therapy. METHODS Medical and imaging records were retrospectively reviewed. Patients were imaged with ultra-widefield fluorescein, indocyanine green angiography, and fundus autofluorescence. Spectral-domain optical coherence tomography was performed to evaluate macular edema and choroidal thickness. Optical coherence tomography angiography excluded macular neovascularization. RESULTS This report summarizes two cases of peripapillary pachychoroid syndrome complicated by very severe bilateral macular edema. In all four eyes, the diffuse intraretinal and subretinal fluid remarkably improved or completely resolved after monthly intravitreal aflibercept injections with commensurate improvement of visual acuity. Multimodal imaging documented the significant improvement of fluid and the reduction in choroidal thickening in response to anti-vascular endothelial growth factor therapy in each case. CONCLUSION Severe cases of peripapillary pachychoroid syndrome associated with vision loss can be successfully treated with intravitreal aflibercept therapy.

Abstract
PURPOSE To investigate the efficacy and safety of brolucizumab in diabetic macular edema (DME) and diabetic retinopathy (DR). METHODS In this systematic review and meta-analysis, an electronic search was done to acquire all articles describing brolucizumab use in patients with DME and DR. The review was prospectively registered on PROSPERO (CRD42022382625). Collected articles were filtered through two stages by independent reviewers. Data were extracted from the included articles and then analyzed accordingly. RESULTS Brolucizumab induced significant improvement in best-corrected visual acuity and was either better or non-inferior to other types of anti-VEGF (MD -0.64 mu, 95% CI [-1.15, -0.13], P = .01); the same observation was noted with regards to central subfield macular thickness (CSMT) (MD -138.6 mu, 95% CI [-151.9, -125.3], P = .00001). Brolucizumab was reported to be relatively safe for use in diabetic patients, with few adverse events observed, with a higher frequency of adverse events in relation to the 3 mg dose compared to the 6 mg dose. CONCLUSION Brolucizumab is a new drug that has potential advantages in efficacy over other anti-VEGF agents in the treatment of DME and DR. It showed significant improvement in BCVA and CSMT with the possibility of a lower dosing schedule compared to other agents. Although observed in low frequency, sight-threatening adverse effects appear to occur more frequently compared to other anti-VEGF agents. The main observed adverse event was retinal vasculitis which was seen more commonly with the 3 mg dose versus the 6 mg dose.

Abstract
To observe alterations in corneal morphology caused by repeated intravitreal injections of anti-vascular endothelial growth factor (VEGF). Prospective cohort study. Seventy-seven eyes were treated with intravitreal injection of anti-VEGF from June 2021 to March 2023. There were 25 eyes of neovascular age-related macular degeneration (nAMD), 24 eyes of diabetic macular edema (DME), and 28 eyes of retinal vein occlusion (RVO). Aflibercept was used in 37 eyes and Ranibizumab was used in 40 eyes. 3 + PRN was used. Corneal endothelium and corneal thickness were measured using a corneal endothelial microscope. The data related to central corneal thickness, corneal endothelial cell density (ECD), average cell size, coefficient of variation (CV), proportion of hexagonal cells (Hex%) was collected. A comparison was also made between baseline and the dynamic changes of all indexes 1 year following the last injection. It was observed that in comparison to baseline, ECD and Hex% decreased significantly after the 3rd injection of Aflibercept and Ranibizumab. However, ECD did not decrease further and remained at the same level as after the last injection. Hex% and average cell size increased to a certain extent in comparison to the last injection. All the changes were found to be statistically significant (P < .01). After 3 injections, ECD in DME group was markedly lower than that in nAMD and RVO group, but the CV in DME group was higher than that in nAMD as well as RVO groups, and all the differences were statistically significant (P < .05). Following intravitreal anti-VEGF therapy, DME is more likely than other disorders to result in a decrease in ECD. Repeated intravitreal injections of anti-VEGF drugs can reduce the Hex% and ECD to a certain extent. After the last injection, Hex% can progressively recover, and ECD can remain stable without further declining. After injections, ECD in DME group was found to be significantly lower than that in nAMD and RVO groups, but CV in DME group was significantly higher in comparison to the other 2 groups. In patients with macular edema, repeated intravitreal injections of anti-VEGF may have certain effects on corneal morphology. Patients with diabetes mellitus in particular should pay special attention to corneal safety following repeated intravitreal injections if they have significantly reduced ECD at baseline.

Abstract
BACKGROUND Diabetic macular edema (DME) is a leading cause of vision loss in patients with diabetes. This study aimed to develop and evaluate an OCT-omics prediction model for assessing anti-vascular endothelial growth factor (VEGF) treatment response in patients with DME. METHODS A retrospective analysis of 113 eyes from 82 patients with DME was conducted. Comprehensive feature engineering was applied to clinical and optical coherence tomography (OCT) data. Logistic regression, support vector machine (SVM), and backpropagation neural network (BPNN) classifiers were trained using a training set of 79 eyes, and evaluated on a test set of 34 eyes. Clinical implications of the OCT-omics prediction model were assessed by decision curve analysis. Performance metrics (sensitivity, specificity, F1 score, and AUC) were calculated. RESULTS The logistic, SVM, and BPNN classifiers demonstrated robust discriminative abilities in both the training and test sets. In the training set, the logistic classifier achieved a sensitivity of 0.904, specificity of 0.741, F1 score of 0.887, and AUC of 0.910. The SVM classifier showed a sensitivity of 0.923, specificity of 0.667, F1 score of 0.881, and AUC of 0.897. The BPNN classifier exhibited a sensitivity of 0.962, specificity of 0.926, F1 score of 0.962, and AUC of 0.982. Similar discriminative capabilities were maintained in the test set. The OCT-omics scores were significantly higher in the non-persistent DME group than in the persistent DME group (p < 0.001). OCT-omics scores were also positively correlated with the rate of decline in central subfield thickness after treatment (Pearson's R = 0.44, p < 0.001). CONCLUSION The developed OCT-omics model accurately assesses anti-VEGF treatment response in DME patients. The model's robust performance and clinical implications highlight its utility as a non-invasive tool for personalized treatment prediction and retinal pathology assessment.

Abstract
BACKGROUND This study investigated the effects of systemic factors in response to intravitreal injections in patients with macular edema due to non-proliferative diabetic retinopathy (NPDR). METHODS We retrospectively reviewed the medical records of patients treated with intravitreal injections for macular edema secondary to NPDR between January 2018 and January 2021. The patients were divided into three groups according to the injection response. When patients with diabetic macular edema showed 20µ or more reduction in central retinal thickness compared to baseline, they were classified as responsive group, and if not, they were classified as refractory group. The responsive group was further divided into the complete and incomplete response groups. Patients with complete disappearance of edema at seven months were classified as the complete response group, whereas those in which edema did not disappear were classified as the incomplete response group. The clinical characteristics of each group, including medical history, ophthalmic examination results, and laboratory examination results at the time of diagnosis, were analyzed. RESULTS Of the 112 eyes (91 patients) that satisfied the inclusion criteria, 89 (77 patients) in the responsive group and 23 (14 patients) in the refractory group were included in the analysis. The responsive group was further divided into the complete (51 eyes) and incomplete (38 eyes) response groups. The refractory group had significantly higher glycated hemoglobin levels and significantly lower estimated glomerular filtration rates than the responsive group (p = 0.026 and p = 0.012, respectively). In the multivariate logistic regression analysis, both factors were found to be significant in predicting the degree of response (all p < 0.05). No factor showed a significant difference between the incomplete and complete response groups(all p > 0.05). CONCLUSIONS In macular edema caused by NPDR, low glomerular filtration rates and high glycated hemoglobin levels may be used as predictors of poor response to intravitreal injection therapy. In addition to blood glucose control, education should be provided regarding the need for the continuous monitoring of renal function.

Abstract
INTRODUCTION Intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) drugs have been widely used in patients with macular edema (ME) secondary to retinal vein occlusion (RVO); however, recurrence is a major concern. This study aims to observe the clinical effects of atorvastatin and intravitreal therapy in the treatment of patients with branch or central RVO-ME and coexistent carotid plaques (CP). METHODS AND ANALYSIS A prospective randomized controlled clinical trial will be conducted. Sixty-four patients diagnosed with branch or central RVO-ME and coexistent CP will be enrolled and randomly allocated in a 1:1 ratio to the control and experimental groups. The control group will be treated with intravitreal conbercept monthly for 3 months, followed by monthly evaluation and injection of pro re nata (PRN) for 12 months, while the experimental group will be treated with oral atorvastatin 20 mg daily combined with the control group treatment. If a drop of best-corrected visual acuity (BCVA) is more than five Early Treatment Diabetic Retinopathy Study (ETDRS) letters (one line) or an increment in central subfield thickness (CSFT) of 100 μm (or a 10% increment from the previous visit), intravitreal re-treatment will be performed. Outcome measurements include CSFT, BCVA, number of injections, and incidence of adverse events during the 12-month follow-up period. Differences between groups will be evaluated using Student's t-test, and comparisons between groups will be evaluated using repeated-measures analysis of variance. ETHICS AND DISSEMINATION The study has been approved by the Institutional Review Board of Nanjing Lishui People's Hospital, Nanjing, China (approval number 2023KY0418-12, dated 18 April 2023), and has been registered on chictr.org.cn. Written informed consent will be collected from each patient and the results of this trial will be submitted to a peer-reviewed journal. TRIAL REGISTRATION Chinese Clinical Trial Registry ChiCTR2300071359. Registered on 12 May 2023.

Abstract
PURPOSE To evaluate imaging findings from SCORE2 participants through 60 months, to describe the degree of resolution or progression of these variables, and to correlate changes in these imaging findings to treatment outcomes such as visual acuity and the number of treatments administered. METHODS SCORE2 participants were followed for up to 60 months. Visual acuity, injection frequency and imaging tests color fundus photography (CFP), optical coherence tomography (OCT), and ultra-widefield fluorescein angiography [UWFA]) were performed throughout this period. RESULTS Less than 6% of eyes had subretinal fluid at month 60. Disorganization of the retinal inner layers (DRIL) was the most likely finding to persist, present in 96% of eyes at baseline and unchanged at 95% at month 60. For UWFA, at baseline, there was a mean of 5.0% non-perfusion area (95% CI: 3.3%-6.8%) in the NETWORC grid with little change to month 60. For the Early Treatment Diabetic Retinopathy Study (ETDRS) grid, at baseline, there was a mean of 2.3% non-perfusion area (95% CI: 0.7%-3.9%) with little change to month 60. There was no correlation between any of the imaging variables at baseline and change in visual acuity to month 60 or in the number of injections following the variable treatment timeframe (month 12 to month 60). CONCLUSIONS These analyses provide an anatomic explanation for persistent functional deficits many years following initial treatment. Clinical practice patterns should consider evaluation with these imaging tests to help explain persistent functional deficits in many eyes. Additionally, these 8 baseline imaging variables generally should not be relied on to predict visual acuity or intensity of treatment.

Abstract
OBJECTIVE To evaluate the association between intravitreal anti-VEGF therapy and visual acuity (VA)/driving vision maintenance over 4 years in patients with neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME). DESIGN Retrospective, observational, clinical practice cohort study using data from the Vestrum Health database. PARTICIPANTS Initial diagnosis (January 1, 2014 to June 30, 2019) of nAMD or DME and ≥ 1 year of treatment/follow-up history. The VA analysis required 4 years of treatment/follow-up history. For the driving vision maintenance analysis, patients required Snellen VA of 20/40 or better at baseline and for ≥ 6 months during year 1 after index intravitreal anti-VEGF treatment in the better-seeing eye. METHODS A loss-of-driving event was the first clinic visit with VA worse than 20/40 sustained for ≥ 6 consecutive months. Kaplan-Meier analyses estimated the probability of maintaining driving vision over 4 years stratified by year-1 injection number. Cox proportional hazard models examined associations between baseline clinical characteristics and year-1 injection frequency and the risk of losing driving vision. MAIN OUTCOME MEASURES Mean change in VA over time and by baseline VA, driving vision maintenance probability over time and stratified by anti-VEGF injection frequency, and baseline factors predictive of driving vision maintenance. RESULTS In year 1, the nAMD and DME cohorts gained 8.5 and 9.5 ETDRS letters, respectively. Between years 1 and 4, patients with nAMD and DME lost 6.6 and 2.7 ETDRS letters, respectively. The probability of maintaining driving vision over 4 years was 56% (nAMD) and 72% (DME); among patients who received 1 to 5, 6 to 7, and ≥ 8 anti-VEGF injections in year 1, corresponding probabilities were 50%, 56%, and 65% (nAMD; P < 0.001) and 63%, 72%, and 77% (DME; P < 0.001). Baseline factors associated with driving vision loss included older age, worse index VA, geographic atrophy (nAMD), and worsening baseline diabetic retinopathy (DME). CONCLUSIONS Older age and worse index VA were risk factors for driving vision loss, whereas a greater year-1 injection number was associated with driving vision maintenance through year 4, supporting early initiation and frequent anti-VEGF injections for maintaining driving vision in nAMD or DME.

Abstract
AIM We assessed the effectiveness of sodium-glucose co-transporter 2 inhibitors (SGLT2is) in reducing the administration frequency of anti-vascular endothelial growth factor (VEGF) agents in patients with diabetic macular oedema (DMO) using a health insurance claims database. MATERIALS AND METHODS This retrospective cohort study analysed health insurance claims data covering 11 million Japanese patients between 2005 and 2019. We analysed the frequency and duration of intravitreal injection of anti-VEGF agents after initiating SGLT2is or other antidiabetic drugs. RESULTS Among 2412 matched patients with DMO, the incidence rates of anti-VEGF agent injections were 230.1 per 1000 person-year in SGLT2i users and 228.4 times per 1000 person-year in non-users, respectively, and the risk ratio for events was unchanged in both groups. Sub-analysis of each baseline characteristic of the patients showed that SGLT2is were particularly effective in patients with a history of anti-VEGF agent use [p = .027, hazard ratio (HR): 0.44, 95% confidence interval (CI): 0.22-0.91]. SGLT2is reduced the risk for the first (p = .023, HR: 0.45, 95% CI: 0.22-0.91) and second (p = .021, HR: 0.39, 95% CI: 0.17-0.89) anti-VEGF agent injections. CONCLUSIONS There was no difference in the risk ratio for the addition of anti-VEGF therapy between the two treatment groups. However, the use of SGLT2is reduced the frequency of anti-VEGF agent administration in patients with DMO requiring anti-VEGF therapy. Therefore, SGLT2i therapy may be a novel, non-invasive, low-cost adjunctive therapy for DMO requiring anti-VEGF therapy.

Abstract
PURPOSE To compare noninfectious outcomes of intravitreal antibiotic steroid (IVAS) injection (moxifloxacin-triamcinolone) and postoperative topical nonsteroidal antiinflammatory drugs (NSAID) with a standard 3-drop therapy (TDT) regimen (topical antibiotic, steroid, and NSAID) in patients after cataract surgery. DESIGN Retrospective comparative clinical cohort study. METHODS In 3 study centers in the United States, a total of 2143 eyes (N = 2143 patients) underwent cataract surgery with IVAS-NSAID or TDT between 2017 and 2022. Preoperative data were included, including patients' age, iris color, medical history, and ocular history. Postoperative data, including best-corrected visual acuity, intraocular pressure (IOP), and the need for IOP-lowering medications, were recorded at 1-week, 1-month, and 6-month time points. The primary outcome measures were postoperative complications, defined as persistent anterior chamber inflammation, persistent corneal edema (PCE), rebound inflammation, and cystoid macular edema, were compared between the 2 groups. RESULTS There were 1079 eyes in the IVAS-NSAID group and 1064 eyes in the TDT group. Best-corrected visual acuity and IOP were similar between IVAS-NSAID and TDT eyes at all time points. A portion (11.6%) of TDT eyes experienced postoperative complications compared with 6.5% in IVAS-NSAID eyes (P < .001). Femtosecond laser-assisted cataract surgery was associated with increased rates of PCE in IVAS-NSAID eyes, and eyes with dark irides had a higher incidence of cystoid macular edema, PCE, and rebound inflammation in the IVAS-NSAID group. CONCLUSION The IVAS-NSAID regimen overall had similar postoperative outcomes and fewer complications compared with the TDT regimen. IVAS-NSAID may be considered a safe alternative to topical regimens in non-femtosecond laser-assisted cataract surgery and patients with light irides.

Abstract
OBJECTIVE To evaluate disorganization of retinal inner layers (DRIL), as detected on spectral-domain optical coherence tomography (OCT) images, as a biomarker for diabetic macular edema (DME) activity, visual function, and prognosis in eyes with DME. DESIGN Longitudinal prospective. METHODS Post hoc correlation analyses were performed on data from a phase 2 clinical trial. Seventy-one eyes of 71 patients with treatment-naive DME received either suprachoroidally administered CLS-TA (proprietary formulation of a triamcinolone acetonide injectable suspension) combined with intravitreal aflibercept or intravitreal aflibercept with a sham suprachoroidal injection procedure. DRIL area, maximum horizontal extent of DRIL, ellipsoid zone (EZ) integrity, and the presence and location of subretinal (SRF) and intraretinal fluid (IRF) were evaluated at baseline and week 24 by certified reading centre graders. RESULTS At baseline, the area and maximum horizontal extent of DRIL were negatively correlated with best-corrected visual acuity (BCVA; r = -0.25, p = 0.05 and r = -0.32, p =0.01, respectively). Mean baseline BCVA progressively worsened with each ordinal drop in EZ integrity, improved with the presence of SRF, and was invariant to the presence of IRF. DRIL area and maximum extent were significantly decreased at week 24 (-3.0 mm2 [p < 0.001] and -775.8 mm [p < 0.001], respectively. At week 24, decreases in the area and maximum horizontal extent of DRIL were positively correlated with increases in BCVA (r = -0.40, p = 0.003 and r = -0.30, p = 0.04). Improvements in BCVA at week 24 were no different between patients showing improvement in EZ, SRF, or IRF and those showing no improvement or worsening from baseline. CONCLUSIONS DRIL area and DRIL maximum horizontal extent were demonstrated to be novel biomarkers for macular edema status, visual function, and prognosis in eyes with treatment-naive DME.

Abstract
OBJECTIVES To assess the risk factors for resistance to first-line therapy and long-term response to dexamethasone intravitreal implant (Ozurdex®) of patients with macular oedema (MO) secondary to rhegmatogenous retinal detachment repair (RRDR). METHODS This was a retrospective, consecutive cohort study conducted in patients who underwent RRDR between January 2014 and December 2020 in the Rothschild Foundation Hospital and experienced postoperative MO (POMO) with a follow-up of at least 18 months. RESULTS Of the 1152 patients screened, 36 eyes (3.1%) experienced POMO. The mean follow-up duration was 45.2 months (18.0-80.5 months). Twenty-five eyes (69.4%) were resistant to first-line therapy and received at least one Ozurdex® injection (mean number: 2.7 [1-12]). The multivariate analysis showed an increased risk of resistance in patients who underwent perfluorocarbon liquid (PFCL)-assisted drainage (adjusted odds ratio: 8.65; 95% confidence interval: 1.97-15.33; p = 0.01). Significant differences in best-corrected visual acuity and central macular thickness were found between before Ozurdex® injection and the last follow-up visit: from 0.57 ± 0.47 LogMAR to 0.34 ± 0.32 LogMAR (p = 0.02) and from 483.0 ± 124.0 µm to 354.6 ± 96.5 µm (p = 0.001), respectively. The absence of serous retinal detachment and the presence of hyperreflective foci at baseline were associated with a higher resistance and a poorer response to Ozurdex®. Two patients (8%) experienced hypertony, that was well controlled with hypotonic drops. CONCLUSION MO secondary to RRDR is challenging. Ozurdex® could be reasonably proposed as first-line treatment, at least when MO occurs following PFCL-assisted drainage, given the favourable long-term benefit/risk ratio.

Abstract
PURPOSE To evaluate the safety and efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids in the postoperative management of cataract surgery for age-related cataract in adults. DESIGN Meta-analysis. METHODS Cochrane, Embase, PubMed, Scopus, Web of Science and CINAHL were searched for articles using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system. The review was registered prospectively with PROSPERO (CRD42022364733). Randomized controlled trials of patients undergoing age-related cataract surgery treated with corticosteroids, NSAIDs, or a combination were included. RESULTS A total of 19 studies were included, with 3473 patients (3638 eyes) treated following cataract surgery with NSAIDs (n = 1479), corticosteroids (n = 1307), or a combination (n = 687). Combination treatment demonstrated favorable best-corrected visual acuity compared to corticosteroids 4 to 6 weeks postoperatively (MD = -0.01 logMAR, 95% CI: -0.02, -0.01, I2 = 0%). NSAIDs had more favorable flare values than corticosteroids on day 7 (MD = -9.17 photons/ms, 95% CI = -16.52, -1.82, I2 = 94%), day 14 (MD = -5.23 photons/ms, 95% CI = -8.35, -2.11, I2 = 94%), and 4 to 6 weeks (MD = -1.62 photons/ms, 95% CI = -3.03, -0.20, I2 = 93%) postoperatively. Furthermore, 4 to 8 weeks postoperatively, patients treated with NSAIDs showed lower central macular thickness (MD = -13.26 µm, 95% CI = -18.66, -7.86, I2 = 81%) compared to those treated with corticosteroids. NSAIDs and combination treatment were associated with a lower incidence of central macular edema (OR = 0.16, 95% CI = 0.07, 0.35, I2 = 61%; OR = 0.21, 95% CI = 0.10, 0.45, I2 = 31%) than corticosteroids 4 to 8 weeks postoperatively. CONCLUSIONS NSAIDs and combination treatments could be regarded as more effective and safer alternatives to corticosteroids alone in the postoperative management of cataract surgery. Further studies should be conducted to determine why this evidence has not been reflected in practice patterns, and to further compare the effectiveness of NSAIDs and combination treatments.

Abstract
PURPOSE To report the 100-week outcomes from the KESTREL and KITE trials. DESIGN Two phase 3, double-masked, active-controlled, randomized trials. METHODS Patients with diabetic macular edema (DME) were randomized 1:1:1 to brolucizumab 3 mg/6 mg (BRO3/BRO6) or aflibercept 2 mg (AFL) in KESTREL (N = 566) or 1:1 to BRO6 or AFL in KITE (N = 360). BRO3/BRO6 arms received 5 loading doses every 6 weeks (q6w) followed by q12w dosing, with an option to adjust to q8w at predefined disease activity assessment visits. In KITE, at week 72, based on the disease stability assessment, treatment intervals could be extended by 4 weeks in the BRO6 arm. AFL arms received 5 monthly loading doses followed by fixed q8w dosing. RESULTS At week 100, change from baseline in BCVA (letters) was +8.8 for BRO6 and +10.6 for AFL in KESTREL; and +10.9 for BRO6 and +8.4 for AFL in KITE. In both studies, fewer BRO6 subjects had intraretinal fluid and/or subretinal fluid than AFL subjects. Results were achieved with 32.9% (KESTREL) and 47.5% (KITE) of BRO6 subjects maintained on q12w and q12w/q16w dosing, respectively. Intraocular inflammation rates for BRO6 vs AFL were 4.2% vs 1.1% (KESTREL) and 2.2% vs 1.7% (KITE), of which retinal vasculitis rates were 0.5% vs 0% in KESTREL, with no cases in KITE. Retinal vascular occlusion rates were 1.6% vs 0.5% (KESTREL) and 0.6% in both treatment arms in KITE. CONCLUSIONS Results show the long-term efficacy and durability of brolucizumab in improving visual and anatomical outcomes in DME; the overall safety profile of brolucizumab remained unchanged through year 2.

Abstract
PURPOSE To compare the outcomes of early or late switching from intravitreal (IV) anti-vascular endothelial growth factor (anti-VEGF) injection to IV Dexamethasone (DEX) implant injection in treatment-naïve patients with macular edema secondary to branch retinal vein occlusion. METHODS This study included 68 eyes of 68 treatment-naïve BRVO patients who started anti-VEGF treatment. After the loading dose, the patients were divided into two groups: Early DEX group (n:34) (DEX implant treatment started after 3 loading doses) and Late DEX group (n:34) (DEX implant treatment started after 6 months). Visual acuity and examination findings were recorded at baseline, 3rd, 6th, and 12th month follow-ups. Optical coherence tomography data were recorded for central macular subfield thickness assessment. RESULTS A total of 30 (44.1%) women and 38 (55.9%) men participated, and the average age was 67.6 ± 6.4 years. The mean letter gains at week 52 was 15.1 and 20.9 in the Early DEX and Late DEX groups, respectively. The group with the highest gain of ≥15 letters was the Late DEX group (26/34 patients) and the gain of ≥15 letters was 14/34 in the Early DEX group (p: 0.006). At week 52, the anatomical gain was 115.3 µm and 136.9 µm in the Early DEX and Late DEX groups, respectively. CONCLUSIONS A gain of 15 or more letters was demonstrated to be higher in patients who switched to DEX implant late after anti-VEGF treatment. If it is necessary to switch, the late switch may be more effective for more visual gain at the end of the first year.

Abstract
PURPOSE To evaluate the safety and effectiveness of various treatment modalities in patients with diabetic retinopathy (DR) who underwent cataract surgery. METHODS A comprehensive search for randomized controlled trials (RCTs) was conducted using the PubMed, Embase, Cochrane Library, and CNKI databases up to December 22, 2021. The safety and efficacy of treatment modalities were assessed using the risk ratio (RR) to compare the progression of DR and the mean difference to evaluate the best corrected visual acuity (BCVA) and macular thickness (MT). RESULTS The meta-analysis of the RCTs revealed that anti-VEGF (anti-vascular endothelial growth factor) drugs significantly reduced the progression of DR [RR: 0.37 (95%CI 0.19, 0.70), P = 0.002] and improved BCVA [mean difference = - 0.06 (- 0.12, - 0.01), P = 0.03] in patients with pre-existing DR who underwent cataract surgery. Steroid drugs also showed a significant reduction in macular thickness [mean difference = - 55.63 (- 90.73, - 20.53), I2 = 56%, P = 0.002] in DR patients two weeks after cataract surgery compared to the control group. The safety profiles of different management options did not differ significantly. CONCLUSION The present meta-analysis suggests that anti-VEGF drugs can effectively slow down the progression of diabetic retinopathy, improve BCVA, and reduce MT in DR patients who underwent cataract surgery. Steroid drugs also show promise in reducing MT. However, further studies with larger sample sizes are required to compare the efficacy and safety of different management options in a multi-center clinical setting.

Abstract
OBJECTIVE To determine the association between pre-operative central subfield thickness (CST) and post-radiotherapy visual acuity (VA), cystoid macular edema (CME), and intravitreal anti-vascular endothelial growth factor (VEGF) requirement. DESIGN Single-center retrospective study. PARTICIPANTS Patients with plaque-irradiated extramacular choroidal melanoma treated between 11/11/2011 and 4/30/2021. Pre-operative CST difference between the affected and unaffected eye was used. Kaplan-Meier analysis and hazard ratios were calculated. RESULTS Of 85 patients, pre-operative CST was greater in the melanoma-affected eye (vs. fellow eye) by mean of 20.4 μm (median 14.0, range - 60.0-182.0). Greater CST at presentation (vs. fellow eye) was associated with larger tumor diameter (p = 0.02), greater tumor thickness (p < 0.001), and more frequent tumor-related Bruch's membrane rupture (p = 0.006). On univariate analysis of outcome data, greater CST at presentation (vs. fellow eye) was associated with higher 5-year risk (1.09 [1.02-1.17], p = 0.02) of VA 20/200 or worse and increased (1.10 [1.01-1.20], p = 0.03) likelihood for anti-VEGF injections after plaque irradiation. There was no significant association with CME. The association between CST and VA outcome remained significant on multivariate analysis accounting for impact of tumor thickness and radiation dose to optic disc, while tumor distance to fovea was the only significant factor on multivariate analysis for anti-VEGF injections. CONCLUSION Greater CST at presentation (vs. fellow eye) was associated with worse VA outcome following plaque radiotherapy for choroidal melanoma. Large-sized tumors may contribute to a higher intraocular VEGF burden, potentially leading to greater preoperative CST, which correlates with poor VA outcome post-plaque radiotherapy.

Abstract
Intravitreal aflibercept injection (IAI) is a treatment for diabetic macular edema (DME), but its mechanism of action (MoA) has not been completely elucidated. Here, we aimed to explore IAI's MoA and its multi-target nature in DME pathophysiology with an in silico (computer simulation) disease model. We used the Therapeutic Performance Mapping System (Anaxomics Biotech property) to generate mathematical models based on the available scientific knowledge at the time of the study, describing the relationship between the modulation of vascular endothelial growth factor receptors (VEGFRs) by IAI and DME pathophysiological processes. We also undertook an enrichment analysis to explore the processes modulated by IAI, visualized the effectors' predicted protein activity, and specifically evaluated the role of VEGFR1 pathway inhibition on DME treatment. The models simulated the potential pathophysiology of DME and the likely IAI's MoA by inhibiting VEGFR1 and VEGFR2 signaling. The action of IAI through both signaling pathways modulated the identified pathophysiological processes associated with DME, with the strongest effects in angiogenesis, blood-retinal barrier alteration and permeability, and inflammation. VEGFR1 inhibition was essential to modulate inflammatory protein effectors. Given the role of VEGFR1 signaling on the modulation of inflammatory-related pathways, IAI may offer therapeutic advantages for DME through sustained VEGFR1 pathway inhibition.

Abstract
Introduction The aim of this study was to better understand the efficacy of various drugs, such as glucocorticoids and anti-vascular endothelial growth factors (VEGF), in the treatment of diabetic macular edema (DME), and to evaluate various clinical treatment regimens consisting of different therapeutic measures. Methods This study included randomized controlled trials up to February 2023 comparing the efficacy of corticosteroid-related therapy and anti-VEGF therapy. PubMed, the Cochrane Library, and Embase were searched, and the quality of the studies was carefully assessed. Finally, 39 studies were included. Results Results at 3-month followup showed that intravitreal injection of bevacizumab (IVB) + triamcinolone acetonide (TA) was the most beneficial in improving best-corrected visual acuity and reducing the thickness of macular edema in the center of the retina in patients with DME. Results at 6-month follow-up showed that intravitreal dexamethasone (DEX) was the most effective in improving patients' bestcorrected visual acuity and reducing the thickness of central macular edema. Discussion Overall, IVB+TA was beneficial in improving best-corrected visual acuity and reducing central macular edema thickness over a 3-month follow-up period, while DEX implants had a better therapeutic effect than anti-VEGF agents at 6 months, especially the patients with severe macular edema and visual acuity impaired.

Abstract
INTRODUCTION In neovascular age-related macular degeneration (nAMD) trials, anti-VEGF injection frequency decreases after the first year, while outcomes remain primarily related to the number of injections. To the best of our knowledge, there are no reports of maintaining the best corrected visual acuity (BCVA) for more than 7 years in extension studies. OBJECTIVE To report a 12-year follow-up of a real-world case of nAMD where BCVA was preserved from declining. CASE DESCRIPTION A 67-year-old Caucasian female presented to our department in June 2010 due to decreased vision in her left eye (LE) within the preceding months. Examination showed a BCVA of 85 letters (L) in the right eye (RE) and 35 L in the LE. Fundus examination showed drusen in the macula of both eyes. Macular edema, loss of the macular lutein pigment, macular hypo/hyperpigmentation were observed in the LE. A diagnosis of Type 2 choroidal neovascular membrane (CNV) in the LE was established and within two months a Type 1 CNV developed in the RE. She undergone 9 injections of bevacizumab (six) and ranibizumab (three) within the first year of treatment in the LE and seven injections of ranibizumab within the first year in the RE. RESULTS The LE had a mean of 5.2 injections per year, and the RE had a mean of 7.5 injections per year, from 2010 to 2022. RE's BCVA dropped by 8L (85L to 77L) and central retinal thickness (CRT) increased by 16 μm (276 μm to 292 μm) while LE's BCVA increased by 28L (35L to 63L) and CRT decreased by 369 μm (680 μm to 311 μm), at the twelfth year. CONCLUSIONS Although the final visual outcome depends on baseline BCVA and lesion type or size, the number of injections is paramount in preserving BCVA and achieving favorable functional outcomes in nAMD, even after 12 years of treatment.

Abstract
To compare baseline characteristics, initial response and 12-month efficacy and safety outcomes in eyes with branch and central retinal vein occlusion (BRVO and CRVO) treated with dexamethasone implants (DEX) or anti-vascular endothelial growth factor (anti-VEGF) we performed a multi-centre, retrospective and observational study using Fight Retinal Blindness! Registry. Of 725 eligible eyes, 10% received DEX initially with very frequent adjunctive anti-VEGF (BRVO-DEX 49%, CRVO-DEX 60%). The primary outcome of mean adjusted change in VA at 12 months with DEX and anti-VEGF initiated groups were not statistically significantly different (BRVO: DEX + 6.7, anti-VEGF + 10.6 letters; CRVO: DEX + 2.8, anti-VEGF + 6.8 letters). DEX initiated eyes had fewer injections and visits than anti-VEGF initiated eyes. The BRVO-DEX eyes had greater initial mean changes in VA and central subfield thickness (CST) and achieved inactivity sooner than BRVO-anti-VEGF eyes. The mean CST after the first three months was above 350 μm in all but the BRVO-anti-VEGF group, suggesting undertreatment. In routine care DEX is uncommonly used when available as initial treatment of BRVO and CRVO requiring supplemental anti-VEGF within the first year. The 12-month outcomes were similar, but DEX initiated eyes had fewer injections and visits but more episodes of raised IOP Vs those starting anti-VEGF.

Abstract
PURPOSE To evaluate the short-term effects (hours-days) of intravitreal dexamethasone implant (IDI) in eyes with diabetic macular edema (DME) refractory to anti-vascular endothelial growth factor (VEGF) injections. METHODS This was a prospective, single-arm, interventional clinical series. Eyes with DME and 3-9 injections of ranibizumab without a good response were included. Patients underwent a single IDI. Best-corrected visual acuity (BCVA) measurement, complete ophthalmic evaluation, and spectral-domain optical coherence tomography (SD-OCT) were performed at baseline, 2 h, 3 h, 24 h, 7 days, and 1 month. The main outcomes were change in central retinal thickness (CRT) on SD-OCT and BCVA. RESULTS Fifteen eyes of 15 patients were included. Mean CRT decreased after treatment from 515.87 µm ± 220.00 µm at baseline to 489.60 µm ± 176.53 µm after 2 h (p = 0.126), and 450.13 µm ± 163.43 at 24 h (p = 0.006). Change in BCVA was from 0.85 ± 0.44 logMAR baseline to 0.58 ± 0.37 log MAR at 1 month (p = 0.003). CONCLUSIONS Eyes treated with IDI showed significant decrease in CRT detectable 1 day after injection. In some patients, the effect could be observed 3 h post-implantation. TRIAL REGISTRATION Clinicaltrials.gov NCT05736081 . Registered 20 February 2023, Retrospectively registered.

Abstract
In ophthalmology, intravitreal operative medication therapy (IVOM) is a widespread treatment for diseases related to the age-related macular degeneration (AMD), the diabetic macular edema, as well as the retinal vein occlusion. However, in real-world settings, patients often suffer from loss of vision on time scales of years despite therapy, whereas the prediction of the visual acuity (VA) and the earliest possible detection of deterioration under real-life conditions is challenging due to heterogeneous and incomplete data. In this contribution, we present a workflow for the development of a research-compatible data corpus fusing different IT systems of the department of ophthalmology of a German maximum care hospital. The extensive data corpus allows predictive statements of the expected progression of a patient and his or her VA in each of the three diseases. For the disease AMD, we found out a significant deterioration of the visual acuity over time. Within our proposed multistage system, we subsequently classify the VA progression into the three groups of therapy "winners", "stabilizers", and "losers" (WSL classification scheme). Our OCT biomarker classification using an ensemble of deep neural networks results in a classification accuracy (F1-score) of over 98%, enabling us to complete incomplete OCT documentations while allowing us to exploit them for a more precise VA modelling process. Our VA prediction requires at least four VA examinations and optionally OCT biomarkers from the same time period to predict the VA progression within a forecasted time frame, whereas our prediction is currently restricted to IVOM/no therapy. We achieve a final prediction accuracy of 69% in macro average F1-score, while being in the same range as the ophthalmologists with 57.8 and 50 ± 10.7 % F1-score.

Abstract
PURPOSE To report the development of bilateral cystoid macular edema after bimatoprost implant (Durysta) injections in both eyes to treat primary open-angle glaucoma. METHODS Case report. RESULTS A 93-year-old woman with a history of primary open-angle glaucoma received bimatoprost implant (Durysta) injections in both eyes 4 weeks apart. The patient subsequently developed progressively decreased visual acuity in both eyes because of bilateral cystoid macular edema, which improved with topical corticosteroid therapy. CONCLUSION Bimatoprost implant (Durysta) can cause cystoid macular edema in susceptible individuals. Patients who received the implant should be assessed for the presence of cystoid macular edema after any decline in visual acuity, particularly in high-risk patients.

Abstract
PURPOSE To report a bilateral reduction in pseudophakic cystoid macular edema (PCME) after unilateral intravitreal injection (IVI) of brolucizumab. OBSERVATIONS A 64-year-old female with bilateral recalcitrant PCME was treated with one dose of intravitreal ozurdex implant and triamcinolone acetonide each in both the eyes, with an equivocal response. On switching to IVI brolucizumab in the right eye (OD), the patient showed significant improvement in the best-corrected visual acuity (BCVA) with a notable reduction in the intraretinal fluid (IRF) and central subfield thickness (CST) in both the eyes at one month. CONCLUSIONS AND IMPORTANCE In conclusion, IVI brolucizumab is effective for the management of recalcitrant PCME with good visual and anatomical outcomes at one month. However, this molecule can also have therapeutic efficacy in the uninjected eye possibly due to systemic escape. More research into the pharmacokinetic properties of this novel molecule is needed to validate our findings.

Abstract
PURPOSE The aim of this study is to compare the efficacy of intravitreal aflibercept (IVA), bevacizumab (IVB), ranibizumab (IVR), and dexamethasone implant (IVDI) in the treatment of serous retinal detachment (SRD) caused by Irvine-Gass syndrome (IGS). DESIGN Retrospective cohort, comparative study. METHODS AND MATERIALS The medical records of 128 eyes with no previous history of intravitreal agents in 128 IGS patients with SRD that received IVA, IVB, IVR, and IVDI monotherapy were retrospectively reviewed. The patients were divided into 4 groups, according to treatment. Patients with recurrence and/or were unresponsive following a course of topical steroids and non-steroidal anti-inflammatory drugs (NSAIDs) were included in the study. Best corrected visual acuity (BCVA), central macular thickness (CMT), subfoveal choroidal thickness (SFCT), and SRD were compared between the 4 treatment groups at baseline, at follow-up months 1, 3, 6, and 12, and at the final follow-up visit. RESULTS Serous retinal detachment completely resolved in 74%, 45.7%, 66.4%, and 40.8% of the eyes at month 1 (P = 0.042), 87%, 50.9%, 75.8%, and 80.9% at month 3 (p = 0.031), 88.9%, 50.4%, 75.7%, 80.2% at month 6 (p = 0.028), 81.7%, 72.8%, 68.7%, 80.1% at month 12 (p = 0.580), and 100%, 66.4%, 87.9%, 93.2% (p = 0.478) at final follow-up visit in the IVA, IVB, IVR, and IVDI groups, respectively. BCVA was significantly better in the IVA group at all follow-up time points (month 1: p < 0.001; month 3: p < 0.001; month 6: p = 0.002; month 12: p = 0.009, final follow-up visit: p < 0.001). CMT was significantly lower in the IVA group at months 3 (p = 0.008), 6 (p = 0.011), and 12 (p = 0.010), and at the final follow-up visit (p < 0.001). Recurrence was observed after a longer period of time and fewer injections were needed in the IVDI and IVA groups (p < 0.05). Resolution of CME was most rapid in the IVA group (p = 0.032). CONCLUSION All intravitreal agents were effective in terms of visual results in the SRD patients; however, eyes treated with IVA and IVDI required fewer injections, as compared to the eyes treated with IVB and IVR. Furthermore, SRD entirely resolved in all eyes in the IVA group at the final follow-up visit.

Abstract
PURPOSE to report a case of bilateral macular edema (ME) secondary to Rituximab infusions in a woman affected by IgG4-Related Disease and to review of prior cases of ME related to Rituximab. OBSERVATIONS ME completely resolved after Intravitreal Dexamethasone Implant (IDI). CONCLUSIONS AND IMPORTANCE ME is a rare complication after Rituximab infusions and very few cases are reported in the literature. Usually, ME occurs a few weeks after systemic administration and is probably related to a local release of cytokines. It resolves with oral, subtenon or intravitreal steroids. Our case is the first showing that IDI is a safe and effective treatment in ME secondary to Rituximab. Rituximab is not required to be discontinued if treatment for ME is started.

Abstract
PURPOSE To evaluate whether sodium-glucose co-transporter 2 (SGLT2) inhibitors affect progression of non-proliferative diabetic retinopathy (NPDR) compared to standard of care. METHODS A retrospective cohort study compared subjects enrolled in a commercial and Medicare Advantage medical claims database who filled a prescription for a SGLT2 inhibitor between 2013 and 2020 to unexposed controls, matched up to a 1:3 ratio. Patients were excluded if they were enrolled for less than 2 years in the plan, had no prior ophthalmologic exam, had no diagnosis of NPDR, had a diagnosis of diabetic macular edema (DME) or proliferative diabetic retinopathy (PDR), had received treatment for vision-threatening diabetic retinopathy (VTDR), or were younger than 18 years. To balance covariates of interest between the cohorts, an inverse probability treatment weighting (IPTW) propensity score for SGLT2 inhibitor exposure was used. Multivariate Cox proportional hazard regression modeling was employed to assess the hazard ratio (HR) for VTDR, PDR, or DME relative to SGLT2 exposure. RESULTS A total of 6065 patients who initiated an SGLT2 inhibitor were matched to 12,890 controls. There were 734 (12%), 657 (10.8%), and 72 (1.18%) cases of VTDR, DME, and PDR, respectively, in the SGLT2 inhibitor cohort. Conversely, there were 1479 (11.4%), 1331 (10.3%), and 128 (0.99%) cases of VTDR, DME, and PDR, respectively, among controls. After IPTW, Cox regression analysis showed no difference in hazard for VTDR, PDR, or DME in the SGLT2 inhibitor-exposed cohort relative to the unexposed group [HR = 1.04, 95% CI 0.94 to 1.15 for VTDR; HR = 1.03, 95% CI 0.93 to 1.14 for DME; HR = 1.22, 95% CI 0.89 to 1.67 for PDR]. CONCLUSION Exposure to SGLT2 inhibitor therapy was not associated with progression of NPDR compared to patients receiving other diabetic therapies.

Abstract
This study investigates the impact of glycosylated hemoglobin (HbA1c) on the efficacy of intravitreal dexamethasone (DEX) implants in patients with diabetic macular edema (DME) over a 12-month period. We retrospectively reviewed 90 DME patients treated with DEX implants, categorizing them based on baseline HbA1c levels (≤ 7% and > 7%) and 12-month changes in HbA1c ("improved", "stable", "worsened"). At the 2-month mark, the mean central subfield thickness (CST) reduction in the HbA1c ≤ 7% group was - 147.22 ± 113.79 µm compared to -130.41 ± 124.50 µm in the > 7% group (p = 0.506). Notably, 12-month outcomes between these groups showed no significant difference. The "improved" HbA1c subgroup experienced a more pronounced CST reduction at 2 months (p = 0.042), with outcomes leveling off with other groups by 12 months. Conclusively, DEX implant outcomes in DME were not influenced by either baseline HbA1c levels or their changes over time. This suggests that local alterations in the inflammation milieu may have a potentially stronger impact on DME treatment outcomes, highlighting the importance of considering local factors in DME treatment.

Abstract
BACKGROUND Branch retinal vein occlusion (BRVO) is a common retinal vascular disease leading to severe vision loss and blindness. This study aimed to investigate and reveal the pathophysiological mechanisms underlying macular edema (ME) recurrence in patients with BRVO through a proteomic approach. METHODS We detected proteins in the aqueous humor of 14 untreated, four refractory, and four post-operative patients with BRVO-ME and 12 age-matched cataract controls using four-dimensional label-free proteomic and bioinformatics analyses. RESULTS In total, 84 proteins exhibited significant differential expression between the BRVO and control samples (fold change [FC] ≥ 1.2 and adjusted p-value < 0.05). Compared to the control group, 43 and 41 proteins were upregulated and downregulated, respectively, in the BRVO group. These proteins were involved in cell adhesion, visual perception, retina homeostasis, and platelet activation. Several significantly enriched signaling pathways included complement and coagulation cascades and platelet activation. In the protein-protein interaction networks generated using the search tool for retrieval of interacting genes (STRING), the fibrinogen alpha chain and fibrinogen beta chain constituted a tightly connected cluster. Many common protein expression trends, such as the fibrinogen alpha chain and fibrinogen beta chain, were observed in both the recurrent and refractory groups. Differentially expressed proteins in the two groups were involved in complement activation, acute-phase response, platelet activation, and platelet aggregation. Important signaling pathways include the complement and coagulation cascades, and platelet activation. Protein-protein interaction analysis suggested that the fibrinogen alpha chain and fibrinogen beta chain constituted a tightly connected cluster. The expression of some differentially expressed proteins shared by the BRVO and the recurrent and refractory groups was reversed in the post-operative group. CONCLUSIONS Our study is the first to analyze the proteomics of recurrent, refractory, and post-operative groups treated for BRVO-ME, and may potentially provide novel therapeutic interventions for the recurrence of ME.

Abstract
Objective This study aimed to investigate and compare the efficacy and safety of retinal laser photocoagulation (PRP) alone, PRP with aflibercept 3+PRN, and PRP with aflibercept 5+PRN in patients with both high-risk proliferative diabetic retinopathy (PDR) and diabetic macular edema (DME). Methods Overall, 170 patients with high-risk PDR and DME (170 eyes from 170 patients) who visited our ophthalmology clinic from December 2018 to December 2020 were divided into the PRP (n=58), aflibercept 5+PRN with PRP (n=53), and aflibercept 3+PRN with PRP (n= 59) groups. General information, such as age, sex, and eye category, was obtained. Moreover, best-corrected visual acuity (BCVA), baseline central macular foveal thickness (CFT), microaneurysm (MA), area of neovascularization (NV), area of hard exudate (HE), and cytokine levels in atrial fluid before and after treatment, were assessed. The χ2 test was used for comparison between groups for statistical data. Analysis of variance was used for the statistical description of measurement data, independent samples were analyzed using Student's t-test, and Student-Newman-Keuls test was used for group comparisons. Differences were considered statistically significant at P < 0.05. Results After treatment, no significant improvement in the BCVA (logMAR) of patients in the PRP group was observed. The BCVA (log MAR) decreased from 0.72 ± 0.17 and 0.74 ± 0.17 to 0.50 ± 0.13 and 0.53 ± 0.17 in PRP with aflibercept 5+PRN and PRP with aflibercept 3+PRN groups, respectively, with a statistically significant difference compared to those in the PRP group (P<0.05 in all cases). However, no statistically significant difference was observed between the combined treatment groups (P>0.05). The CFT in the PRP-only group decreased slightly from 361.80 ± 36.70 μm to 353.86 ± 40.88 μm, with no statistically significant difference (P>0.05), whereas the CFT in the aflibercept 5+PRN with PRP and aflibercept 3+PRN with PRP groups decreased from 356.57 ± 37.57 μm and 358.17 ± 44.66 μm to 284.87 ± 31.52 μm and 303.19 ± 37.00 μm, respectively, with statistically significant differences before and after treatment (P<0.05 for both groups). Statistically significant differences were observed in CFT between the three groups after treatment (P<0.05 in all cases). The number of MA (pcs) in the PRP, aflibercept 5+PRN with PRP, and aflibercept 3+PRN with PRP groups decreased from 118.34 ± 27.96, 118.60 ± 33.34, and 116.59 ± 28.95 to 92.95 ± 29.04, 44.60 ± 20.73, and 54.26 ± 25.43, respectively. The two-way comparison of the three groups revealed statistically significant differences in MA (P<0.05 in all cases). In the three groups, NV decreased from 1.00 ± 0.21 mm², 1.01 ± 0.18 mm², and 0.98 ± 0.20 mm² before treatment to 0.49 ± 0.17 mm², 0.31 ± 0.16 mm², and 0.38 ± 0.14 mm², respectively, with statistically significant differences (P<0.05 in all cases). After 12 months of treatment, 13, 18, and 18 patients had reduced HE area in the PRP-only, aflibercept 5+PRN with PRP, and aflibercept 3+PRN with PRP groups, respectively, with statistically significant differences (P<0.05 in all cases). After 12 months of treatment, vascular endothelial growth factor, monocyte chemoattractant protein-1, and glial fibrilliary acidic protein levels (pg/mL) in the aqueous humor decreased in both combined treatment groups compared with that at baseline, with statistically significant differences; however, no significant difference was observed between the two combined treatment groups (P>0.05). Conclusion Aflibercept 5+PRN combined with PRP was safe and effective in treating patients with high-risk PDR and DME, and was more effective than PRP-only and aflibercept 3+PRN with PRP in improving CFT and MA.

Abstract
BACKGROUND The mainstay of treatment in diabetic macular edema (DME) is intravitreal administration of anti-vascular endothelial growth factors (anti-VEGFs). Aqueous depressants may enhance the effects of anti-VEGF agents by prolonging their clearance via aqueous outflow. PURPOSE To compare the anatomical and functional outcomes of treatment with intravitreal bevacizumab (IVB) and topical timolol-dorzolamide versus IVB alone. METHOD In this randomized placebo-controlled clinical trial, patients with center-involving DME (ci-DME) and best corrected visual acuity (BCVA) of 20/30 or less were enrolled and randomly allocated to two treatment arms. One group received three monthly IVB injections and timolol-dorzolamide eye drops twice a day (IVB + TD group); the other group received three monthly IVB injections and artificial tear drops as placebo (IVB group). Patients underwent ophthalmic evaluations and macular optical coherence tomography scans at baseline and 1 month after the third injection. RESULT Forty-six eyes from 46 patients with ci-DME were recruited. There was no intergroup difference regarding age, gender distribution, diabetic retinopathy stage, glycemic indices, BCVA, central macular thickness (CMT), or intraocular pressure at baseline. BCVA was significantly improved in the IVB + TD group (0.46 ± 0.18 to 0.36 ± 0.18 logarithm of the minimum angle of resolution [logMAR], p = 0.002), in contrast to IVB group (0.40 ± 0.17 to 0.35 ± 0.22 logMAR, p = 0.113). Similarly, the IVB + TD group showed a significant reduction in CMT (p < 0.001), unlike the IVB group (p = 0.086); and the CMT change in the former was greater than in the latter (- 0.57 ± 57.67 vs. - 25.52 ± 68.02 μm, p = 0.033). CONCLUSION Our findings support the short-term effectiveness of topical timolol-dorzolamide as adjunctive therapy to IVB injections in managing center-involving DME in terms of anatomical and visual outcomes.

Abstract
Purpose Diabetic macular edema (DME) is a sight-threatening complication of diabetes. Consequently, studying the proteome of DME may provide novel insights into underlying molecular mechanisms. Methods In this study, aqueous humor samples from eyes with treatment-naïve clinically significant DME (n = 13) and age-matched controls (n = 11) were compared with label-free liquid chromatography-tandem mass spectrometry. Additional aqueous humor samples from eyes with treatment-naïve DME (n = 15) and controls (n = 8) were obtained for validation by enzyme-linked immunosorbent assay (ELISA). Best-corrected visual acuity (BCVA) was evaluated, and the severity of DME was measured as central subfield thickness (CST) employing optical coherence tomography. Control samples were obtained before cataract surgery. Significantly changed proteins were identified using a permutation-based calculation, with a false discovery rate of 0.05. A human donor eye with DME and a control eye were used for immunofluorescence. Results A total of 101 proteins were differentially expressed in the DME. Regulated proteins were involved in complement activation, glycolysis, extracellular matrix interaction, and cholesterol metabolism. The highest-fold change was observed for the fibrinogen alpha chain (fold change = 17.8). Complement components C2, C5, and C8, fibronectin, and hepatocyte growth factor-like protein were increased in DME and correlated with best-corrected visual acuity (BCVA). Ceruloplasmin and complement component C8 correlated with central subfield thickness (CST). Hemopexin, plasma kallikrein, monocyte differentiation antigen CD14 (CD14), and lipopolysaccharide-binding protein (LBP) were upregulated in the DME. LBP was correlated with vascular endothelial growth factor. The increased level of LBP in DME was confirmed using ELISA. The proteins involved in desmosomal integrity, including desmocollin-1 and desmoglein-1, were downregulated in DME and correlated negatively with CST. Immunofluorescence confirmed the extravasation of fibrinogen at the retinal level in the DME. Conclusion Elevated levels of pro-inflammatory proteins, including the complement components LBP and CD14, were observed in DME. DME was associated with the loss of basal membrane proteins, compromised desmosomal integrity, and perturbation of glycolysis.

Abstract
PURPOSE To compare the anatomical and functional outcomes of the combination of aflibercept and dexamethasone implant (CT) against aflibercept monotherapy (AM) in treatment-naive diabetic macular edema (DME) patients with serous macular detachment and hyperreflective foci. METHODS This study included 82 eyes of 82 patients with treatment-naive DME who completed the follow-up period of 12 months. All patients had optical coherence tomography biomarkers of an inflammatory DME phenotype. Patients were consecutively selected and classified into two groups: The CT group consisted of 39 eyes treated with aflibercept therapy and initially combined with a single-dose dexamethasone implant. The AM group consisted of 43 eyes treated with aflibercept alone. The primary outcome measures of the study were the mean reduction of the central macular thickness (CMT) and total macular volume parameters (TMV) and improvement in best-corrected visual acuity. RESULTS In both groups, the patient characteristics, including age, gender, duration of diabetes, HbA1c levels, phakic percentage, and diabetic retinopathy status were similar (P > 0.05). The mean reduction in CMT and TMV was significantly higher in the CT group compared to the AM group (P < 0.001 and P = 0.002, respectively). In contrast, mean letter gains were not significantly higher (P = 0.240) at the end of the study. In the CT group, 20.5% of patients showed a transient IOP increase, and 18% developed cataracts. In subgroup analysis, the mean letter gain in pseudophakic eyes was significantly higher (12.5 in the CT vs. 9.3 in the AM group, P = 0.027). CONCLUSION The CT, where inflammation is prominent, can provide faster recovery. The pseudophakic eyes seem to be the ideal patient group for CT.

Abstract
Ranibizumab, is a humanized, monoclonal antibody fragment that binds and inactivates vascular endothelial growth factor-A (VEGF-A) and VEGF-B. One of the main indications for an intravitreal treatment with ranibizumab is age-related macular degeneration (AMD), which is a retinal disease with a high worldwide socioeconomic impact. Biosimilars constitute biological products that demonstrate similar pharmacodynamic and pharmacokinetic characteristics with a reference product, as well as comparable clinical efficacy, safety and immunogenicity. Since the approval of the first biosimilar Razumab, there has been a variety of new biosimilars available on the market. They offer the advantage of the same good clinical and safety results at a better price. All Ranibizumab biosimilars that have gained approval were tested in double masked Phase 3 clinical studies. The use of Ranibizumab biosimilars in neovascular AMD is well reported in the bibliography. Nevertheless, over the last few years, there is a tendency of using biosimilars in other retinal diseases like retinopathy of prematurity (ROP), diabetic macular edema (DME) or polypoidal choroidal vasculopathy (PCV). In conclusion, ranibizumab biosimilars offer a promising avenue for the management of retinal diseases, especially in countries with lower socioeconomic status, where there is lack of availability of innovator ranibizumab. However, further research is required to fully explore their efficacy, safety, and long-term outcomes in a plethora of retinal diseases.

Abstract
BACKGROUND To systematically evaluate the efficacy and safety of subthreshold micropulse laser (SML) combined with anti-vascular endothelial growth factor (VEGF) drugs for the treatment of diabetic macular edema (DME). METHODS The randomized controlled trials on SML combined with anti-VEGF drugs for DME were retrieved from China National Knowledge Infrastructure, Wan Fang Data, VIP Data, Sino Med (China Biomedical Literature Database), PubMed, Web of Science, The Cochrane Library, and Embase by computer from inception to April 19, 2022. The observation group was treated with SML combined with anti-VEGF drugs, while the control group was treated with anti-VEGF agents alone or SML. And the references of the included literature were manually searched. The Meta-analysis was performed using Revman 5.4 and STATA SE 15. RESULTS This study finally included 15 randomized controlled trials involving 891 eyes for Meta-analysis. The results showed that there was no statistically significant difference between the 2 groups in best-corrected visual acuity at 1, 3, 6, 9, and 12 months after treatment. There was no statistical difference between the 2 groups in central macular thickness (CMT) at 1, 3, and 6 months after treatment (P > .05). CMT in the observation group was lower than that in the control group at 9 and 12 months (P < .05). There was no statistical difference between the 2 groups in total macular volume at 3, 6, 9, and 12 months in CMT (P > .05). The number of anti-VEGF drugs injections in the observation was lower than that in the control group (P < .05). The occurrence of complications between the 2 groups was not statistically significant difference (P > .05). CONCLUSION SML in combination with anti-VEGF drugs in patients with DME are comparable in reducing the number of anti-VEGF drugs injections and CMT, thereby reducing the financial burden on patients. It does not differ in best-corrected visual acuity and total macular volume.

Abstract
Compromised vascular endothelial barrier function is a salient feature of diabetic complications such as sight-threatening diabetic macular edema (DME). Current standards of care for DME manage aspects of the disease, but require frequent intravitreal administration and are poorly effective in large subsets of patients. Here we provide evidence that an elevated burden of senescent cells in the retina triggers cardinal features of DME pathology and conduct an initial test of senolytic therapy in patients with DME. In cell culture models, sustained hyperglycemia provoked cellular senescence in subsets of vascular endothelial cells displaying perturbed transendothelial junctions associated with poor barrier function and leading to micro-inflammation. Pharmacological elimination of senescent cells in a mouse model of DME reduces diabetes-induced retinal vascular leakage and preserves retinal function. We then conducted a phase 1 single ascending dose safety study of UBX1325 (foselutoclax), a senolytic small-molecule inhibitor of BCL-xL, in patients with advanced DME for whom anti-vascular endothelial growth factor therapy was no longer considered beneficial. The primary objective of assessment of safety and tolerability of UBX1325 was achieved. Collectively, our data suggest that therapeutic targeting of senescent cells in the diabetic retina with a BCL-xL inhibitor may provide a long-lasting, disease-modifying intervention for DME. This hypothesis will need to be verified in larger clinical trials. ClinicalTrials.gov identifier: NCT04537884 .

Abstract
PURPOSE Clinical outcome and switch patterns with bevacizumab first treatment strategy for patients with newly diagnosed neovascular age-related macular degeneration (nAMD). METHODS Retrospective observational study of the number of intravitreal injections of bevacizumab and treatment switch in patients who started intravitreal bevacizumab injections between January 1, 2016 and December 30, 2018. RESULTS From January 1 2016 to December 31 2018, 608 eyes of 565 patients started intravitreal injections of bevacizumab for a new diagnosis of nAMD. Average visual acuity (VA) at presentation was 0.60 logarithm of the minimum angle of resolution (logMAR), which improved to 0.47 after six injections (P < 0.001) and decreased to 0.63 at the last follow-up (P = 0.543). Switch of treatment was recommended for 190 eyes (31.3%), and of them, 91 patients (15%) were switched during the first 6 months and defined as primary failure of bevacizumab. The switch of treatment resulted in a statistically significant improvement in VA in the first 6 months after the switch. The gain in VA was not sustainable over time. CONCLUSION Bevacizumab first treatment strategy produced results that were comparable to previous real-world outcomes publications of ranibizumab and aflibercept treatment with low rates of failure of bevacizumab treatment. Treatment switch to second-line treatment yielded a significant VA improvement, mainly in patients with primary bevacizumab failure.

Abstract
PURPOSE To identify predictive factors that help determine the interval of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection after the initial resolution of diabetic macular edema (DME). METHODS This retrospective case-control study enrolled treatment-naïve DME patients who had achieved DME resolution after intravitreal anti-VEGF injections. Patients were classified into the recurrence and no-recurrence groups, depending on the development of recurrent DME after deferring intravitreal anti-VEGF injection. The demographics and clinical features, including optical coherence tomography findings, were compared between the two groups. RESULTS We enrolled 105 eyes. Sixty eyes (57.1%) belonged to the no-recurrence group, and 45 (42.9%), belonged to the recurrence group. The severity of diabetic retinopathy at baseline was related to early DME recurrence (P = 0.009). At the treatment deferring point, the non-recurrence group had both thinner central subfield thickness (289.5 ± 27.2 μm vs. 307.0 ± 38.2 μm, P = 0.011) and thinner central retinal thickness (214.9 ± 41.4 μm vs. 231.8 ± 41.2 μm, P = 0.043) compared to the recurrence group. Intraretinal cyst was observed in 34 eyes (56.7%) in the no-recurrence group and 42 eyes (93.3%) in the recurrence group at the deferring point (P < 0.001). CONCLUSION A low risk of early DME recurrence is anticipated in the eyes with foveal thinning and no intraretinal cyst when anti-VEGF injection is deferred. These predictive biomarkers can be useful for patient monitoring and determining treatment strategies for DME patients.

Abstract
BACKGROUND Concerns about the generalizability of pivotal randomized controlled trials (pRCTs) findings have been raised. We aimed to compare intravitreal dexamethasone implants' (IDIs) effectiveness for diabetic macular edema (DME) and central retinal vein occlusion (CRVO), between eyes eligible and ineligible for pRCTs. METHODS This retrospective cohort study analyzed Taiwan's Chang Gung Research Database, including DME or CRVO eyes initiating IDIs during 2015-2020. We classified all treated eyes as eligible or ineligible for pRCTs following major selection criteria of the MEAD and GENEVA trials, and evaluated three-, six-, and twelve-month changes in central retinal thickness (CRT) and visual acuity (VA) after initiating IDIs. RESULTS We included 177 IDI-treated eyes (DME: 72.3%; CRVO: 27.7%), of which 39.8% and 55.1% were ineligible for DME and CRVO pRCTs, respectively. LogMAR-VA and CRT changes at different times were comparable in DME eyes eligible (LogMAR-VA difference: 0.11 to 0.16; CRT difference: -32.7 to -96.9 μm) and ineligible (LogMAR-VA difference: -0.01 to 0.15; CRT difference: -54.5 to -109.3 μm) for the MEAD trial. By contrast, CRVO eyes ineligible for the GENEVA trial had greater LogMAR-VA changes (0.37 ~ 0.50) than those eligible (0.05 ~ 0.13), with comparable CRT reductions (eligible eyes: -72.3 to -106.4 μm; ineligible eyes: -61.8 to -110.7 μm) (all p-values <0.05 of the mean differences between eligible and ineligible CRVO eyes for all follow-ups). CONCLUSIONS IDIs had similar VA and CRT outcomes among DME eyes, regardless of pRCT-eligibility. However, among CRVO eyes, those ineligible for pRCTs showed greater deterioration in VA than those eligible.

Abstract
PURPOSE This pilot study aims to comprehensively evaluate the effects of sub-Tenon's injection of triamcinolone acetonide (STTA) on glycemic control in patients with diabetic macular edema (DME) using professional continuous glucose monitoring (CGM). METHODS This retrospective study analyzed changes in glycemic control in 20 patients with type 2 mellitus and DME following single STTA (20 mg/0.5 mL) using The FreeStyle Libre Pro system. Professional CGM provides core CGM metrics such as the percentage of time that glucose levels fall within a target range and include the time in range (TIR) (70-180 mg/dL), time above range (TAR) (> 180 mg/dL), and time below range (TBR) (< 70 mg/dL). Outcome measures were the changes in CGM metrics (TIR, TAR and TBR) and the percentage of patients in whom TAR increased by at least 10 percentage points (ppt) 4 days before to 4 days after STTA administration. RESULTS The mean CGM metrics (TIR/TAR/TBR) were 75.5%/19.9%/4.4% 4 days before STTA and 73.7%/22.4%/3.5% 4 days after STTA; the metrics 4 days before and 4 days after STTA were not significantly different (P = 0.625 for TIR, P = 0.250 for TAR, and P = 0.375 for TBR). TAR increased by more than 10 ppt in four (20%) patients treated with sulfonylurea and/or insulin. CONCLUSION Although there were no significant changes in the CGM metrics, four patients developed CGM-measured hyperglycemia after STTA for DME.
