Abstract
This retrospective study aimed to investigate the progression of central retinal vein occlusion (CVO) prior to treatment initiation and its impact on prognosis. Of the 54 studied eyes with acute CVO, the average logMAR visual acuity (VA) at the initial visit was 0.65 ± 0.49 with an average time to treatment of 14.9 ± 14.5 days. VA at the initial treatment was identified as a stronger predictor of VA at the final visit compared to VA at the first visit or other factors. Patients who received treatment more than 28 days after the initial visit experienced a significant decline in VA compared to those treated within 28 days (0.21 ± 0.35 vs. 0.04 ± 0.13, p = 0.006). Additionally, patients who were treated between 15 and 28 days showed a greater decrease in VA compared to those treated within 14 days (0.12 ± 0.46 vs. 0.018 ± 0.02, p = 0.026). These findings from the current retrospective analysis suggesting that there is a possibility of VA decline at the initial treatment associating with worse prognosis even when treatment is administered within a month should be further investigated in the prospective study. Also, it may be crucial to consider frequent monitoring of acute CVO patients for initiating treatment at the optimal timing.

Abstract
Thrombosis of retinal veins is one of the most common retinal vascular diseases that may lead to vascular blindness. The latest epidemiological data leave no illusions that the burden on the healthcare system, as impacted by patients with this diagnosis, will increase worldwide. This obliges scientists to search for new therapeutic and diagnostic options. In the 21st century, there has been tremendous progress in retinal imaging techniques, which has facilitated a better understanding of the mechanisms related to the development of retinal vein occlusion (RVO) and its complications, and consequently has enabled the introduction of new treatment methods. Moreover, artificial intelligence (AI) is likely to assist in selecting the best treatment option for patients in the near future. The aim of this comprehensive review is to re-evaluate the old but still relevant data on the RVO and confront them with new studies. The paper will provide a detailed overview of diagnosis, current treatment, prevention, and future therapeutic possibilities regarding RVO, as well as clarifying the mechanism of macular edema in this disease entity.

Abstract
OBJECTIVE Investigate disparities in retinal vein occlusion (RVO) presentation and initiation of anti-VEGF treatment. DESIGN Retrospective cohort study. SUBJECTS Patients in the American Academy of Ophthalmology IRIS® (Intelligent Research in Sight) Registry database (2015-2021) with branch or central RVO and macular edema (ME). METHODS The association of demographic characteristics and presenting visual acuity (VA) with anti-VEGF treatment initiation were quantified using multivariable logistic regression. MAIN OUTCOME MEASURES Treatment with ≥ 1 anti-VEGF injection within 12 months after RVO diagnosis. RESULTS A total of 304 558 eligible patients with RVO and ME were identified. Age at presentation varied by race, ethnicity, sex, and RVO type (all P values < 0.001). Within the first year after RVO presentation, 192 602 (63.2%) patients received ≥ 1 anti-VEGF injection. In a multivariable regression model adjusting for relevant covariates, female (vs. male) patients had lower odds of receiving injections (odds ratio [OR], 0.95; 95% confidence interval [CI], 0.93-0.96; P < 0.0001) as did Black/African American (vs. White) patients (OR, 0.90; 95% CI, 0.88-0.92; P < 0.0001) and Asian (vs. White) patients (OR, 0.95; 95% CI, 0.91-0.99; P = 0.02), whereas older patients (vs. patients aged < 51 years) had higher odds (61-70 years: OR, 1.20; 95% CI, 1.16-1.24; 71-80 years: OR, 1.20; 95% CI, 1.16-1.24; > 80 years: OR, 1.15; 95% CI, 1.11-1.18; all P values < 0.0001). Hispanic (vs. non-Hispanic) patients had a small increased odds of treatment initiation (OR, 1.08; 95% CI, 1.04-1.11; P < 0.0001). Results were similar in the subset of 226 143 patients with VA data. In this subset, patients with presenting VA < 20/40 to 20/200 were most frequently treated in the first year after diagnosis (∼ 70%) and patients with light perception/no light perception (LP-NLP) vision or VA of 20/20 or better were treated least frequently (36.9% and 41.9%, respectively). CONCLUSIONS In this large national clinical registry, 37% of RVO patients with ME had no anti-VEGF treatment documented in the first year after diagnosis. Black/African American, Asian, and female patients and patients with VA of LP-NLP were least likely to receive treatment. Awareness of this undertreatment and these disparities highlight the need for initiatives to ensure all RVO patients receive timely anti-VEGF injections for optimized visual outcomes.

Abstract
PURPOSE To investigate the incidence, treatment patterns, and visual outcomes in patients with branch retinal vein occlusion (RVO) and central RVO before and during the COVID-19 pandemic in a country with no mandatory lockdown. METHODS This retrospective study included 788 patients presenting with a RVO during the years 2019 to 2022 at St. Erik Eye Hospital. The control group and study groups consisted of patients presenting before and during the pandemic, respectively. RESULTS The incidence of diagnosed RVO cases decreased from 281 patients before the pandemic to 236 patients during the first year of the pandemic ( P < 0.05). In patients with branch RVO at the end of follow-up, the best-corrected visual acuity improved 10.3 letters (95% confidence intervals [CI] 7.6-12.9) in the control group compared with 14.3 letters (95% CI 12.6-16.0) in the study groups ( P < 0.05). In patients with central RVO, the best-corrected visual acuity improved 6.3 letters (95% CI 2.7-10.0) in the control group compared with 8.6 letters (95% CI 5.7-11.4) in the study groups (p = NS). Overall, the number of intravitreal anti-vascular endothelial growth factor injections increased from 7.0 (95% CI 6.6-7.3) in the control group to 7.6 (95% CI 7.4-7.8) in the study groups ( P < 0.05). CONCLUSION Good visual and anatomical outcomes were sustained, and the number of intravitreal anti-vascular endothelial growth factor injections increased significantly in patients with RVO during the COVID-19 pandemic.

Abstract
INTRODUCTION This systematic review and meta-analysis aimed to provide an updated evidence base for clinical decision-making by comparing the efficacy and safety of aflibercept 2 mg and ranibizumab in treating retinal vein occlusion (RVO). METHODS A systematic search was conducted using eight databases up to December 2021. Randomized controlled trials (RCTs) and real-world studies (RWSs) comparing aflibercept and ranibizumab in patients with RVO were evaluated. The primary outcomes assessed were efficacy, number of injections administered, and adverse events. RESULTS Three RCTs (424 patients) and 11 RWSs (1415 patients) were included. For central RVO (CRVO), RCTs demonstrated a comparable efficacy, whereas RWSs showed that mean changes from baseline in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) were significantly greater with aflibercept compared to ranibizumab; the number of injections of aflibercept was fewer than that of ranibizumab in RCTs, but similar in RWSs. For branch RVO (BRVO), no statistically significant difference in efficacy between the two drugs in RCTs/RWSs was observed, with fewer injections of aflibercept at 12 months in RWSs. The safety profiles of both drugs were similar for both CRVO and BRVO. CONCLUSIONS For CRVO, aflibercept had similar efficacy and safety profile but with fewer injections versus ranibizumab in RCTs; RWSs showed greater BCVA improvement and CRT reduction with aflibercept than ranibizumab. For BRVO, RCTs showed similar in efficacy, safety, and injection numbers for both drugs, while RWSs demonstrated that aflibercept required fewer injections at 12 months of follow-up. Overall, this study provides updated evidence for clinical decision-making in the treatment of RVO.

Foveal Thickness Fluctuations in Anti-VEGF Treatment for Central Retinal Vein Occlusion. OPHTHALMOLOGY SCIENCE 2024; 4:100418. [PMID: 38146527 PMCID: PMC10749270 DOI: 10.1016/j.xops.2023.100418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 09/26/2023] [Accepted: 10/19/2023] [Indexed: 12/27/2023]
Abstract
Purpose The aim of this study was to examine the effects of foveal thickness (FT) fluctuation (FTF) on 2-year visual and morphological outcomes of eyes with central retinal vein occlusion (CRVO) undergoing anti-VEGF treatment for recurrent macular edema (ME) based on a pro re nata regimen. Design Retrospective, observational case series. Participants We analyzed 141 treatment-naive patients (141 eyes) with CRVO-ME at a multicenter retinal practice. Methods We assessed FT using OCT at each study visit. Patients were divided into groups 0, 1, 2, and 3 according to increasing FTF. Main Outcome Measures We evaluated the logarithm of the minimal angle of resolution (logMAR) best-corrected visual acuity (BCVA), the length of the foveal ellipsoid zone (EZ) band defect measured using OCT, and the association of FTF with VA and EZ band defect length. Results The mean baseline logMAR BCVA and FT were 0.65 ± 0.52 (Snellen equivalent range: 20/20-20/2000) and 661.1 ± 257.4 μm, respectively. The mean number of anti-VEGF injections administered was 5.6 ± 3.6. At the final examination, the mean logMAR BCVA and FT values were significantly improved relative to the baseline values (both P < 0.01). During the observation, BCVA longitudinally improved in Groups 0 and 1, remained unchanged in Group 2, and worsened in Group 3. Likewise, the length of the foveal EZ band defect did not increase in Group 0; however, it gradually increased in Groups 1, 2, and 3. Foveal thickness fluctuation was significantly and positively associated with the logMAR BCVA and length of the foveal EZ band defect at the final examination (P < 0.01). The final logMAR BCVA of patients developing neovascular complications was 1.27 ± 0.72 (Snellen equivalent range: 20/50-counting fingers), which was significantly poorer than that of patients without complications (P < 0.001). There was no significant difference in the neovascular complication rate among the FTF groups (P = 0.106, Fisher exact test). Conclusions In eyes receiving anti-VEGF treatment for CRVO-ME, FTF can longitudinally impair the visual acuity and foveal photoreceptor status during the observation period, thus influencing the final outcomes. However, neovascular complications, which would also lead to a poor visual prognosis, may not be associated with FTF.

Abstract
INTRODUCTION AURIGA is the largest real-world study to date to evaluate intravitreal aflibercept (IVT-AFL) treatment of diabetic macular edema or macular edema secondary to retinal vein occlusion (RVO) in routine clinical practice. Here, we report the 24-month outcomes in the RVO cohort from France, Germany, Italy, and Taiwan. METHODS AURIGA (NCT03161912) was a prospective observational study. Eligible patients with RVO were enrolled for whom the decision to treat with IVT-AFL had already been made by the attending physician. Patients were treated with IVT-AFL for up to 24 months at physician discretion according to local practice. The primary endpoint was mean change in visual acuity (VA; Early Treatment Diabetic Retinopathy Study [ETDRS] letters) from baseline to month (M) 12. All statistical analyses were descriptive. RESULTS In 554 treatment-naïve and 65 previously treated patients with RVO, the respective mean (95% confidence interval) change in VA from baseline was + 12.5 (10.8, 14.3) and + 7.9 (3.3, 12.6) letters by M12 and + 11.4 (9.4, 13.3) and + 4.4 (- 0.6, 9.5) letters by M24 (baseline mean ± standard deviation: 51.0 ± 21.9 and 51.9 ± 20.4 letters); 44.0% of treatment-naïve and 27.9% of previously treated patients reported ≥ 15-letter gains by M24. By M24, the mean change in central retinal thickness from baseline was - 247 (- 267, - 227) µm in treatment-naïve patients and - 147 (- 192, - 102) µm in previously treated patients. From baseline to M6, M12, and M24, treatment-naïve patients received a total of 4.0 ± 1.3, 5.5 ± 2.5, and 6.9 ± 4.2 injections, respectively, and previously treated patients received 3.8 ± 1.5, 5.0 ± 2.2, and 6.3 ± 3.7 injections, respectively. The safety profile of IVT-AFL was consistent with that of previous studies. CONCLUSIONS In AURIGA, patients with RVO experienced clinically relevant functional and anatomic improvements following IVT-AFL treatment in routine clinical practice. These improvements were largely maintained in treatment-naïve patients over the 24-month study despite the decreasing treatment frequency, suggesting long-term durability of IVT-AFL treatment outcomes.

Abstract
PURPOSE To evaluate the efficacy and safety of intravitreal anti-vascular endothelial growth factor (anti-VEGF) and corticosteroid combination therapy for the management of treatment-naïve or recurrent/refractory macular edema caused by retinal vein occlusion (RVO) in comparison with anti-VEGF monotherapy. METHODS In this systematic review and meta-analysis study, the data from publications in the electronic databases including PubMed, Embase, Cochrane Library Central Register of Controlled Trials, ISI and Scopus from January 1, 2007, through November 20, 2020, were compiled. Heterogeneity was statistically quantified by the I2 statistic, and meta-analysis was performed using a random-effects model. RESULTS Twenty-four related studies were identified, including a total of 1280 eyes, which consisted of 685 and 507 patients with central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO), respectively. This study demonstrated a greater improvement in best-corrected visual acuity (BCVA) in the combination group compared to anti-VEGF monotherapy for both CRVO and BRVO cases at 6 months after initiating therapy. The improvement in vision was more notable in BRVO cases than in CRVO cases. However, the changes in central macular thickness (CMT) did not differ significantly between the different treatment approaches, and the results were inconclusive. Including all cases with RVO, there was no inferiority in terms of BCVA improvement and CMT reduction in the triamcinolone subgroup compared with the slow-release dexamethasone implant subgroup. A greater improvement was noticed in terms of BCVA in the sequentially treated subgroup compared to the simultaneous treatment subgroup, while there was a greater reduction in CMT in the simultaneous subgroup with the highest reduction recorded at 1 month after treatment. CONCLUSIONS This study suggests that combination therapy with intravitreal anti-VEGF and corticosteroid (such as intravitreal or subtenon triamcinolone or dexamethasone implant) has a slightly better effect on improving BCVA in cases with BRVO or CRVO at 6 months compared to monotherapy.

Abstract
INTRODUCTION The purpose of this study was to report the real-world treatment outcomes using a treat-and-extend intravitreal bevacizumab protocol in cystoid macular oedema (CMO) secondary to central retinal vein occlusion (CRVO). METHODS We conducted a retrospective case series of consecutive adult patients with CMO secondary to CRVO who presented between 1st January 2019 and 31st December 2021. All included patients were treated with bevacizumab using a treat-and-extend protocol, were followed up for a minimum of 6 months and had a clinical examination including best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) at every visit. The primary outcome measure was mean change in BCVA. RESULTS Thirty-three eyes of 33 patients were included in the study. The mean change in BCVA from baseline was + 24.5 (Median 18, SD 21.5) letters, with a mean follow-up duration of 18.5 (SD 8.9) months. The mean number of injections was 9.5 (SD 1.9) in year 1 and 7.8 (SD 2.8) in year 2. 87.9% of patients were still requiring active treatment, with a maximum interval achieved of 4-weekly in 18.2%, 6-weekly in 42.4%, 8-weekly in 6.1%, 10-weekly in 15.2%, and 12-weekly in 6.1%. The mean maximum interval achieved of those requiring ongoing treatment was 6.8 (SD 2.4) weeks. Multiple regression analyses showed that a higher baseline BCVA was negatively associated with mean visual acuity gain (P < 0.001) and positively associated with final BCVA (P < 0.001). CONCLUSION The use of intravitreal bevacizumab in a treat-and-extend regimen is effective in treating CMO secondary to CRVO, in a real-world setting.

J Clin Med 2023; 12:6710. [PMID: 37959176 PMCID: PMC10649895 DOI: 10.3390/jcm12216710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 10/16/2023] [Accepted: 10/21/2023] [Indexed: 11/15/2023] Open
Abstract
PURPOSE This study aims to investigate the factors influencing post-treatment visual acuity (VA) in patients with central retinal vein occlusion (CRVO) with macular edema (ME). METHODS The subjects of this study were patients who visited our clinic from May 2013 to July 2019 and who could be followed up with for at least 12 months. Cases with hemi CRVO were excluded from this study. Factors considered in the evaluation of visual prognosis at the 12 months included initial best-corrected VA, central subfoveal thickness, CRVO subtype (nonischemic, ischemic, or converted from nonischemic to ischemic), time taken for the first treatment, number of anti-vascular endothelial growth factor agent injections, structural changes in the inner and outer retinal layers, and the presence of macular ischemia in a multiple regression analysis. RESULTS There were 41 patients with 41 eyes, 27 males and 14 females. The mean age of the patients was 70.5 ± 12.2 (mean ± standard deviation) years. The mean VA was 0.544 ± 0.576, 0.456 ± 0.568, and 0.586 ± 0.665 at the initial visit, 12 months later, and time of last observation, respectively. There were no significant differences in VAs observed between the baseline, month 12, and final visit. Multiple regression analysis revealed that the external limiting membrane score at month 12 (p = 0.030), the VA at initial visit (p < 0.001), and the presence of severe macular ischemia (p < 0.001) were the key factors associated with VA at month 12. Moreover, severe macular ischemia was identified as the only factor affecting decimal VA less than 20/200 at the last observation (p = 0.0092). CONCLUSIONS Severe macular ischemia is strongly linked to a poor visual prognosis in patients with ME associated with CRVO.

Abstract
Although diabetic retinopathy (DR) is clinically diagnosed as a vascular disease, many studies find retinal neuronal and visual dysfunction before the onset of vascular DR. This suggests that DR should be viewed as a neurovascular disease. Prior to the onset of DR, human patients have compromised electroretinograms that indicate a disruption of normal function, particularly in the inner retina. They also exhibit reduced contrast sensitivity. These early changes, especially those due to dysfunction in the inner retina, are also seen in rodent models of diabetes in the early stages of the disease. Rodent models of diabetes exhibit several neuronal mechanisms, such as reduced evoked GABA release, increased excitatory glutamate signaling, and reduced dopamine signaling, that suggest specific neuronal deficits. This suggests that understanding neuronal deficits may lead to early diabetes treatments to ameliorate neuronal dysfunction.

Abstract
Purpose Dual inhibition of angiopoietin-2 and VEGF-A with faricimab (Vabysmo) offers excellent visual acuity gains with strong durability in patients with diabetic macular edema (ME) and neovascular age-related macular degeneration. The phase III BALATON/COMINO (NCT04740905/NCT04740931) trials will investigate the efficacy, safety, and durability of faricimab in patients with ME due to retinal vein occlusion (RVO). Design Two identically designed global, randomized, double-masked, active comparator-controlled studies. Participants Anti-VEGF treatment-naive patients with branch, central, or hemiretinal RVO. Methods Patients were randomized to 6 monthly injections of faricimab 6.0 mg or aflibercept 2.0 mg. From weeks 24 to 72, all patients received faricimab 6.0 mg administered in up to 16-week intervals using an automated treatment algorithm to generate a treat-and-extend-based personalized treatment interval dosing regimen. Personalized treatment interval adjustments were based on changes in central subfield thickness (CST) and best-corrected visual acuity (BCVA). Main Outcome Measures Primary end point was noninferiority of faricimab versus aflibercept in mean change from baseline in BCVA (week 24; noninferiority margin: 4 letters). Secondary end points (weeks 0-24) were mean change from baseline in BCVA, CST, and National Eye Institute Visual Function Questionnaire 25 composite score; proportion of patients gaining or avoiding loss of ≥ 15/≥ 10/≥ 5/> 0 letters. Secondary end points (weeks 24-72) were treatment durability (week 68); continuation of weeks 0 to 24 end points. Ocular/nonocular adverse events will be assessed. Results In total, 1282 patients across 22 countries were enrolled (BALATON, 553 patients, 149 centers; COMINO, 729 patients, 193 centers). Conclusions Using a novel automated interval algorithm, BALATON/COMINO will evaluate the efficacy and safety of faricimab for ME secondary to RVO and provide key insights into how to personalize treatment.

Efficacy of a Modified Treat-and-Extend Aflibercept Regimen for Macular Oedema in Eyes with Central Retinal Vein Occlusion: 2-Year Prospective Study. J Clin Med 2023; 12:5089. [PMID: 37568491 PMCID: PMC10419814 DOI: 10.3390/jcm12155089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 07/24/2023] [Accepted: 07/31/2023] [Indexed: 08/13/2023] Open
Abstract
This prospective, multicentre, interventional study evaluated the efficacy of a modified treat-and-extend (mTAE) aflibercept regimen as personalized therapy for macular oedema (MO) due to central retinal vein occlusion (CRVO). Fifty eyes were studied from 50 patients who were enrolled between November 2016 and July 2019. All patients received intravitreal aflibercept (IVA) injections on an mTAE regimen for 24 months. Primary outcome measures were best-corrected visual acuity (BCVA) and central subfield thickness (CST) at 12 months. Secondary endpoints were BCVA and CST at 24 months. Mean (standard deviation) baseline BCVA (logMAR) and CST were 0.50 (0.51) and 557 (240) µm, respectively. BCVA and CST showed significant improvements at month 12 (0.19 (0.38) and 275 (98) µm, respectively; both p < 0.0001, paired t-test). BCVA and CST also showed significant improvements at 24 months (0.26 (0.50) and 255 (91) µm, respectively, p = 0.0004 and p < 0.0001, paired t-test). The mean numbers of IVA injections and clinic visits over the 24-month study period were 6.2 (3.0) and 10.3 (1.0), respectively. The mTAE regimen of IVA injections for MO due to CRVO was effective in improving BCVA and decreasing CST at 24 months. The mTAE regimen might be an effective personalized therapy for CRVO.

Am J Ophthalmol 2023; 252:101-110. [PMID: 37030494 DOI: 10.1016/j.ajo.2023.03.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 03/25/2023] [Accepted: 03/27/2023] [Indexed: 04/10/2023]
Abstract
PURPOSE To evaluate what clinical gains can be achieved over conventional treatment with ranibizumab alone for central retinal vein occlusion (CRVO) when causal pathology is additionally addressed successfully with a laser-induced chorio-retinal anastomosis (L-CRA). DESIGN Two-year extension of prospective, randomized controlled clinical trial. METHODS A total of 58 patients with macular edema secondary to CRVO were randomized 1:1 to receive either an L-CRA (n = 29) or sham procedure (n = 29) at baseline and then monthly intravitreal ranibizumab 0.5 mg. Outcomes (best corrected visual acuity [BCVA], central subfield thickness [CST], injection requirements) were monitored in the monthly pro re nata (PRN) ranibizumab phase from months 7 to 48. RESULTS Injection requirements for patients with a functioning L-CRA (24 of 29) during the monthly PRN period from 7 to 24 months were a mean (95% CI) of 2.18 (1.57, 2.78) injections compared to 7.07 (6.08, 8.06) (P < .0001) for control (ranibizumab alone). These decreased further over the next 2 years to 0.29 (0.14, 0.61) compared to 2.20 (1.68, 2.88) (P < .001) for the third year and 0.25 (0.11, 0.56) and 1.84 (1.34, 2.54) for the fourth year (P < .001). Mean BCVA was statistically different at all follow-up time points from month 7 through month 48 for the group with the functioning L-CRA compared to the control monotherapy group. This improved to 14.06 letters at month 48 (P = .009). There was no difference in CST between any of the groups over the 48 months of follow-up. CONCLUSION For CRVO patients, addressing causal pathology in addition to conventional therapy improves BCVA and reduces injection requirements.

Abstract
PURPOSE To investigate the lower visual acuity threshold for recommending intravitreal injection therapy (IVI). The lower limit of 1.3 logMAR best-corrected visual acuity (BCVA) was adopted in 2006 and has been maintained since then. METHODS In this retrospective study, data from patients with a logMAR BCVA ≤ 1.3 and 24 months follow-up were analysed. We included patients with neovascular age-related macular degeneration (nAMD), diabetic macular oedema (DME), or retinal vein occlusion (RVO). RESULTS The data from 164 patients (nAMD: 107; DME: 15; RVO: 42) were analysed. We observed a significant improvement at all time intervals (0 to 6, 6 to 12, 12 to 18, and 18 to 24 months after initiating IVI) compared to baseline. Across all indications, median BCVA improved from 1.4 to 1.0 within the first 6 months and remained stable within 24 months. Patients received a median of 5 and 10 injections within 6 and 24 months, respectively. Median foveal retinal thickness was 594.5 μm at baseline and dropped to 244.5 μm, 235.5 µm, 183 µm, and 180 µm during the four consecutive time intervals. CONCLUSION Patients with nAMD, DME, and RVO with poor baseline BCVA may also benefit from intravitreal therapy with VEGF-inhibitors. In the present study, we observed functional and morphological improvement over 2 years irrespective of the underlying macular disease. Those patients should not be excluded from therapy.

Abstract
INTRODUCTION Retinal vein occlusion (RVO) is the second leading cause of blindness from retinal vascular disease behind diabetic retinopathy. Anti-vascular endothelial growth factor (VEGF) and glucocorticoid therapy are the cornerstones of pharmaceutical treatment for RVO. There is considerable interest in developing new pharmaceuticals in and out of these two classes to reduce costs, lower injection burden, and treat the occlusion itself, rather than the complications. AREAS COVERED In this review, we discuss novel pharmaceuticals for the treatment of RVO outside of current standard of care. We performed a comprehensive literature search encompassing pharmaceuticals that have recently been approved or have shown promising results in early clinical trials or animal models. EXPERT OPINION Anti-VEGF therapy remains the most efficacious treatment for RVO with a very favorable side effect profile. New biosimilars reduce costs while maintaining efficacy. Novel glucocorticoids may be a useful therapy in patients for whom anti-VEGF therapy has failed, or as an adjunct. Pharmaceuticals in other drug classes, particularly those with neuroprotective or regenerative properties, as well as those geared toward treating the occlusion itself, represent exciting options for early RVO therapy, but are likely years away from clinical relevance.

Abstract
Branch retinal vein occlusions are a significant cause of vision loss and present several ophthalmic and systemic risk factors, including age, hypertension, hyperlipidemia and glaucoma. Retinal vein occlusion is the second-most-common retinal vascular disease. This study evaluated the effects of Ozurdex in contrast to a combination therapy with anti-vascular endothelial growth factor (VEGF) and cortisone in treatment-naive branch retinal vein occlusions-macular edema (BRVO-ME) cases, at 4-month and 6-month follow-ups. Thirty eyes were included in the study, which were divided into two groups. The first group consisted of 15 eyes, and each received 1 injection of dexamethasone intravitreal implant Ozurdex (DEX). The second group of 15 eyes received 3 intravitreal injections, the first and second with the anti-vascular endothelial growth factor aflibercept and the third one with 4 mg of triamcinolone acetonide (Vitreal S), spaced at one month. The best corrected visual acuity (BCVA) results suggested that the peak efficacy was at 4 months for both groups, with mean values of 0.5 LogMAR and 0.4 LogMAR. Regarding macular edema, there were no significant changes between the 4- and 6-month follow-up periods, with mean values of 361 μm and 390 μm. Six patients experienced transient raised intraocular pressure at one week after treatment. This study highlights the benefits to visual acuity of the combination of anti-vascular endothelial growth factor and cortisone, which represents a viable solution with similar results to Ozurdex therapy.

Abstract
BACKGROUND Anti-vascular endothelial growth factor (VEGF) therapy is currently the most effective therapy of exudative age-related macular degeneration (AMD). The aim of this study was to assess long-term benefits of intensive aflibercept and ranibizumab anti-VEGF therapy in patients with exudative AMD. METHODS Two clinical trial sites recruited their original subjects for a re-evaluation 7 years after the baseline visit of the phase-3 Vascular Endothelial Growth Factor (VEGF) Trap-Eye: Investigation of Efficacy and Safety in Wet Age-Related Macular Degeneration (VIEW 2) trial. Forty-seven eyes of 47 patients with AMD originally treated with ranibizumab (14 eyes) or aflibercept (33 eyes) were included. RESULTS Mean number of injections was 17.8 ± 3.0 during participation in the VIEW 2 trial. Fourteen of 47 (30%) eyes were given additional injections with a mean number of 5.7 ± 4.5 after the trial. At a mean follow-up time of 82 ± 5 months best corrected visual acuity (BCVA) remained stable or improved (≤ 10 letters lost) in 55% of patients in the entire study population, in 43% in the ranibizumab group and in 60% in the aflibercept group. In both groups combined mean BCVA was 54 ± 13 letters at baseline, 65 ± 17 letters at the end of the intensive phase and 45 ± 25 letters at the end of follow-up. There was no statistically significant difference in BCVA between the two groups at baseline (p = 0.88) and at the end of follow-up (p = 0.40). Macular atrophy was observed in 96% of eyes, average area was 7.22 ± 6.31 mm2 with no statistically significant difference between groups (p = 0.47). Correlation between BCVA at end-of-follow-up and the area of atrophy was significant (p < 0.001). At the end of follow-up, fluid was detected in 7 of 47 eyes (15%) indicating disease activity. CONCLUSION Long-term efficacy of aflibercept and ranibizumab was largely consistent. Following a two-year intensive therapy with as-needed regimen, BCVA was maintained or improved in almost half of the patients and in the ranibizumab group and more than half of the patients in the aflibercept group with very few injections. In a remarkable proportion of eyes, BCVA declined severely which underlines the need for long-term follow-ups and may indicate a more prolonged intensive therapy. TRIAL REGISTRATIONS VIEW 2 study: ClinicalTrials.gov ID: NCT00637377, date of registration: March 18, 2008. Long-term follow-up: IRB nr.: SE RKEB 168/2022, ClinicalTrials.gov ID: NCT05678517, date of registration: December 28, 2022, retrospectively registered.

Quantitative cone contrast threshold testing in patients with differing pathophysiological mechanisms causing retinal diseases. Int J Retina Vitreous 2023; 9:9. [PMID: 36732855 PMCID: PMC9893567 DOI: 10.1186/s40942-023-00442-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Accepted: 01/10/2023] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Cone contrast threshold testing (CCT) provides quantitative measurements of color and contrast function to reveal changes in vision quality that are not standard endpoints in clinical trials. We utilize CCT to measure visual function in patients with multiple sclerosis (MS), age-related macular degeneration (AMD), epiretinal membrane (ERM), and retinal vein occlusion (RVO). METHODS Retrospective data was gathered from 237 patients of the Gavin Herbert Eye Institute. Subjects included 17 patients with MS, 45 patients with AMD, 41 patients with ERM, 11 patients with RVO, and 123 healthy controls. Patients underwent the primary measurement outcome, CCT testing, as well as Sloan visual acuity test and spectral domain optical coherence tomography during normal care. RESULTS Color and contrast deficits were present in MS patients regardless of history of optic neuritis. AMD with intermediate or worse disease demonstrated reduced CCT scores. All 3 stages of ERM demonstrated cone contrast deficits. Despite restoration of visual acuity, RVO-affected eyes demonstrated poorer CCT performance than unaffected fellow eyes. CONCLUSIONS CCT demonstrates color and contrast deficits for multiple retinal diseases with differing pathophysiology. Further prospective studies of CCT in other disease states and with larger samples sizes is warranted.

Reported Rates of Intraocular Inflammation with Intravitreal Aflibercept Administered via Pre-Filled Syringe or from Vials in Clinical Practice Between 2012 and 2022. Clin Ophthalmol 2023; 17:385-390. [PMID: 36726365 PMCID: PMC9886133 DOI: 10.2147/opth.s393519] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Accepted: 12/23/2022] [Indexed: 01/28/2023] Open
Abstract
Purpose To determine the reported rates of intraocular inflammation (IOI) in patients treated with intravitreal aflibercept (IVT-AFL) 2 mg in routine clinical practice (ie, outside interventional studies), across all indications and within all countries (excluding the United States), with access to either the vial presentation or pre-filled syringe (PFS). Patients and methods A search was conducted using the Bayer EYLEA® Global Safety Pharmacovigilance Database for reported cases of IOI and IVT-AFL use between October 2012 and March 31, 2022. Results With more than 10 years of post-marketing experience with the IVT-AFL vial presentation (>25 million sold units), and over 2 years of experience with the PFS of IVT-AFL (>6.7 million sold units) the rate of any IOI, including endophthalmitis, outside the United States was 0.3 events per 10,000 units for the PFS and 1.2 events per 10,000 units for the vial presentation. The event rates specifically for endophthalmitis were 0.1 per 10,000 units for the IVT-AFL PFS and 0.6 per 10,000 units for the IVT-AFL vial presentation. Conclusion In patients with retinal diseases treated in routine clinical practice with IVT-AFL either from a vial or the PFS, medically important adverse events of IOI, and in particular, endophthalmitis, are infrequently reported events. Numerically, reported rates of IOI and endophthalmitis are low for the vial presentation and even lower for the PFS.

Choroidal thickness as a possible predictor of non-response to intravitreal bevacizumab for macular edema after retinal vein occlusion. Sci Rep 2023; 13:451. [PMID: 36624124 PMCID: PMC9829912 DOI: 10.1038/s41598-023-27753-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 01/06/2023] [Indexed: 01/11/2023] Open
Abstract
To evaluate outcomes of intravitreal bevacizumab (IVB) treating macular edema (ME) after retinal vein occlusion (RVO) following pro re nata (PRN) regimen and investigate potential predictors of non-response. Retrospective analysis of 126 treatment-naive eyes with ME after RVO. Eyes were treated initially with IVB of 1.25 mg/ml. Therapy was switched in case of non-response. Outcome measures included best-corrected visual acuity (BCVA) and central macular thickness (CMT), which were recorded over 4 years of treatment. BCVA improved significantly during first 2 years. CMT decreased significantly during the 4-year follow-up period. Switching was required in 42 eyes (33%). 34 eyes (26.9%) were switched to steroids, while 8 eyes (6.3%) were switched to other anti-VEGF due to diagnosed glaucoma. Switching occurred after 12.4 ± 8.3 months and an average of 8 ± 4.1 IVBs. Compared with the treatment-responsive group, the treatment-unresponsive group had significantly worse BCVA, higher CMT and subfoveal choroidal thickness (SFCT) at baseline. Treatment IVB following PRN regimen showed significant functional and anatomic improvement in patients with ME after RVO. Switching was required in more than one third of eyes. Higher baseline SFCT could be considered as predictor for non-response to such therapy and thus an indicator of early switching.

Abstract
PURPOSE To evaluate the vision-related quality of life (VR-QOL) before and after intravitreal ranibizumab injections (IVR) for central retinal vein occlusion (CRVO) and to investigate subscale items of VR-QOL in detail. STUDY DESIGN A multicenter, open-label, prospective and comparative study. METHODS Twenty-three patients with treatment naïve CRVO and 22 age-matched normal controls were included. VR-QOL was assessed by 25-Item Visual Function Questionnaire (VFQ-25) before and up to 12 months post-treatment. The VFQ-25 composite score and 12 subscales were compared between CRVO patients and normal controls. RESULTS The VFQ-25 composite scores of CRVO patients showed significant improvement throughout the treatment period compared with baseline. The VFQ-25 composite scores both before and after treatment for CRVO were significantly lower than in normal controls. The subscale items, including general health, general vision, near activities, social functioning, mental health, role difficulties, dependency, and peripheral vision in CRVO, were significantly lower than in the normal controls even after treatment. CONCLUSION Vision-related QOL was low in patients with CRVO before treatment and improved with IVR. In spite of the improvements, several subscale items remained lower than in normal controls following treatment. Attention should be paid to the patients with CRVO and their decreased visual, social and psychological QOL.

Abstract
Purpose To assess and analyze the visual outcomes of patients with retinal vein occlusions in a real-world setting with a long-term follow-up of more than 5 years. Methods Retrospective analysis of 56 patients having retinal vein occlusions from a tertiary eye center, with a mean follow-up of 7 years was performed. Primary outcome measures were mean change in best-corrected visual acuity (BCVA) from baseline at 6 months, 1 year, 2 years, 3 years, and final visit (≥5 years), proportion of patients having BCVA better than 20/40 and worse than 20/200, and mean number of injections. Secondary outcome measures were change in central macular thickness (CMT), development of subsequent retinal vein occlusion (RVO) in same eye or the other eye, and development of neovascular complications. Results The mean change in letter score was + 11.84 in branch RVO (BRVO), +7.14 in non-ischemic central RVO (CRVO), and -9.5 in ischemic CRVO at 1 year, which changed to + 8.57, -5 and - 24, respectively, at the end of follow-up. CMT had improved from 506 ± 98.8 μm, 576.44 ± 149 μm, and 618 ± 178.27 μm, respectively, at baseline to 267 ± 94 μm, 345.20 ± 122.61 μm, and 265.50 ± 107.75 μm, respectively, in BRVO, non-ischemic, and ischemic hemi RVO (HRVO)/CRVO groups. The total mean number of injections given in BRVO, non-ischemic CRVO, and ischemic CRVO groups were 4.6, 6.6, and 4.1, respectively. None of the patients with BRVO developed neovascular glaucoma (NVG). Non-ischemic to ischemic HRVO/CRVO conversion was noted in 4/11 eyes at a mean duration of 12.6 months. NVG was noted in 7/9 eyes (77.8%) in initial ischemic CRVO/HRVO group and 3/4 (75%) converted eyes. Conclusion Patients with BRVO have good visual outcomes with anti-VEGF, while in CRVO results may vary considerably owing to patient compliance and treatment burden on long-term follow-up in a real-world setting.

Abstract
PurposeTo evaluate the efficacy and safety of antivascular endothelial growth factor (anti-VEGF) agents in treating macular oedema due to retinal vein occlusion (RVO-ME).MethodsStudies of randomised controlled trials were searched in PubMed, EMBASE, Cochrane databases and ClinicalTrials.gov registry. RevMan V.5.4 software and GRADE were used to synthesise the data and validate the evidence, respectively.ResultsSeventeen studies were included in this meta-analysis. The anti-VEGF agents showed significant better mean best-corrected visual acuity (BCVA) improvement, more patients with ≧15 Early Treatment in Diabetic Retinopathy Study (ETDRS) letters gained and fewer patients with ≧15 ETDRS letters lost, more effectiveness at reducing central retinal thickness (CRT) and improving the quality of life than sham and steroids both at 6 and 12 months. Compared with laser, the anti-VEGF agents showed significant BCVA improvement and more effectiveness at CRT both at 6 and 12 months. The proportion of eyes gaining ≧15 ETDRS letters was greater in the anti-VEGF group at 6 months. The anti-VEGF and other three groups reported similar levels of non-ocular serious adverse events (SAEs). The incidence of eye pain was significantly higher in the anti-VEGF group than in the sham group. There was a significant increase in the incidence of ocular AEs and conjunctival haemorrhage in the anti-VEGF group compared with the laser group. The incidence of elevated intraocular pressure and cataract was significantly higher in the steroid group than in the anti-VEGF group.ConclusionsThis meta-analysis suggested that treatment of ME secondary to RVO with anti-VEGF improves visual and anatomical outcomes compared with other treatments. Thus, anti-VEGF treatment is the first choice for treating patients with ME secondary to RVO.

Abstract
PURPOSE To analyze the 3-year outcomes in a broad population of patients starting VEGF inhibitors for central retinal vein occlusion (CRVO) in routine clinical practice. DESIGN Observational database study. PARTICIPANTS Overall, 527 treatment-naïve CRVO eyes that commenced VEGF inhibitors between December 1, 2010 and 2018 were tracked in the Fight Retinal Blindness! registry. METHODS Longitudinal models were used to plot changes in visual acuity (VA) and central subfield thickness (CST). MAIN OUTCOME MEASURES Mean change in VA from baseline to 36 months, injections, visits, completion, switching, and suspensions of therapy > 180 days at the final review. RESULTS Overall (527 eyes) mean VA change (95% confidence interval [CI]) was + 10 (7, 12) letters, 37% had final VA ≥ 70 and 30% ≤ 35 letters, mean CST changed -306 μm. Completers (257/527, 49%) had mean 36-month changes in VA and CST of + 12 letters and -324 μm with a median of 18 injections at 26 visits. The adjusted mean VA change was similar to each VEGF inhibitor (mean, + 11.4 letters) despite a greater reduction in CST with aflibercept (-310 μm) versus ranibizumab (-258 μm) versus bevacizumab (-216 μm; P < 0.001). Eyes with baseline VA that was trial-eligible (19-73 letters; 356/527, 68%) gained 7 letters, very poor (< 19 letters; 129/527, 24%) gained 22 letters, or very good (> 73 letters; 42/527, 8%) lost 7 letters. Switching (160/527, 30%) was most often to aflibercept (79 eyes). By using suspensions and discontinuation reasons, we identified similar proportions had ceased therapy (154/527, 29%) and were still receiving it at 36 months (165/527, 31%). Only 62/527 eyes (12%) had resolution of macular edema without treatment for > 6 months. CONCLUSIONS Patients with CRVO that commenced VEGF inhibitors in routine care for whom follow-up was available had VA improvements of around 12 letters at 3 years, but with > 50% lost to follow-up, the VA outcome for the entire group was likely worse. The choice of VEGF inhibitor influenced CST but not VA outcomes. We estimated that around half of the eyes were still receiving injections after 36 months.

Abstract
Abstract
Introduction:
To observe macular microvascular changes in patients with ischemic and non-ischemic central retinal vein occlusion (CRVO) by optical coherence tomography angiography (OCTA), and explore the value of OCTA in differentiating ischemic and non-ischemic CRVO.
Methods:
Cross sectional study. Fifty patients diagnosed as CRVO with macular edema were included. Macular edema in all patients were regressive after three consecutive anti-VEGF treatment. Patients were divided into ischemic and non-ischemic group according to ultra-wide-angle fundus fluorescein angiography (UWFFA). All patients underwent BCVA, IOP, color fundus photography, UWFFA and OCTA. The following parameters were measured: (1) Vessel density (VD): superficial and deep whole VD (SVD, DVD), superficial and deep central fovea VD (SFVD, DFVD), superficial and deep parafoveal VD (SPFVD, DPFVD); (2) Central foveal retinal thickness (CRT); (3) Area of foveal avascular zone (FAZ), perimeter of FAZ (PERIM), avascular index of FAZ (AI) and VD within a width of 300 microns around the FAZ region (FD-300). Comparison between ischemic and non-ischemic group was performed by two independent sample t-tests. Receiver operating characteristic (ROC) curve analysis was used to measure the area under the curve (AUC) of VD for predicting ischemic CRVO.
Results:
There were no significant differences in IOP, SFVD, DFVD and CRT between ischemic and non-ischemic group, and significant differences in age, BCVA, SVD, SPFVD, DVD, DPFVD, FAZ area, PERIM, AI and FD-300 between ischemic and non-ischemic group. ROC curve analysis showed AUC of DVD and DPFVD in predicting ischemic CRVO was highest (0.962). the threshold was 38.40%, and the sensitivity was 100%, but the specificity of DVD (92.3%) was significantly higher than that of DPFVD (84.6%). Therefore, DVD ≤ 38.40% can be used as the best threshold for determining ischemic CRVO.
Conclusion:
OCTA can quantitatively evaluate the macular microvascular structure of CRVO, which is helpful to distinguish ischemic from non-ischemic CRVO.

Abstract
Retinal occlusive diseases are common diseases that can lead to visual impairment. Retinal artery occlusion and retinal vein occlusion are included in the clinical entity, but they have quite different pathophysiologies. Retinal artery occlusion is an emergent eye disorder. Retinal artery occlusion is mainly caused by thromboembolism, which frequently occurs in conjunction with life-threatening stroke and cardiovascular diseases. Therefore, prompt examinations and interventions for systemic vascular diseases are often necessary for these patients. Retinal vein occlusion is characterized by retinal hemorrhage and ischemia, which may impair visual function via several complications such as macular edema, macular ischemia, vitreous hemorrhage, and neovascular glaucoma. Even though anti-vascular endothelial growth factor therapy is the current established first-line of treatment for retinal vein occlusion, several clinical studies have been performed to identify better treatment protocols and new therapeutic options. In this review, we summarize the current findings and advances in knowledge regarding retinal occlusive diseases, particularly focusing on recent studies, in order to provide an update for a better understanding of its pathogenesis.

Real-Life Efficacy of Bevacizumab Treatment for Macular Edema Secondary to Central Retinal Vein Occlusion according to Pro Re Nata or Treat-and-Extend Regimen in Eyes with or without Epiretinal Membrane. J Ophthalmol 2022; 2022:6288582. [PMID: 36225608 PMCID: PMC9550471 DOI: 10.1155/2022/6288582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Revised: 09/14/2022] [Accepted: 09/19/2022] [Indexed: 11/17/2022] Open
Abstract
Purpose. To present real-life data of patients with macular edema (ME) secondary to central retinal vein occlusion (CRVO) treated with bevacizumab (BVZ); determine the possible influence of epiretinal membrane (ERM) on treatment efficacy; and compare treatment outcomes in a treat-and-extend regimen (TER) versus pro re nata (PRN). Methods. We carried out a retrospective analysis of 58 eyes (56 patients) with new-onset CRVO treated only with intravitreal bevacizumab according to TER or PRN. Outcome measures were best-corrected visual acuity (BCVA) and central retinal thickness (CRT) at baseline and 12 months after the first treatment, number of visits and injections, and presence of ERM confirmed by optical coherence tomography in the first 6 months. Results. At 12 months, the mean number of injections was 6.3 across all eyes, with significantly more injections given in TER (
). Mean CRT improved from 627 μm to 359 μm (
) in all eyes, with improvement noted in TER (
), PRN (
), ERM (
), and non-ERM (
) subgroups. The mean BCVA gain was +13.6 letters, and the mean BCVA improved from 0.81 to 0.54 LogMAR (
) in all eyes. BCVA improvement from baseline was significant in TER (
) and non-ERM (
) but not in PRN (
) or ERM (
) subgroups. Seven eyes, all receiving PRN treatment, developed neovascularization. Conclusions. Intravitreal bevacizumab according to either PRN or TER resolved edema and stabilized vision in the first 12 months, with TER yielding significant visual improvement and avoiding neovascular complications. ERM had no influence on bevacizumab efficacy in reducing ME in CRVO during 12 months of treatment.

Abstract
BACKGROUND To investigate the relationship between risk factors for retinal artery occlusion (RAO) and retinal vein occlusion (RVO) and thereby identify similarities and differences between the two types of retinal vascular occlusions. METHODS In this case-control study, 5708 patients with RAO were included and matched with three patients with RVO each. The patients with RVO were matched on sex and age at index date. All patients, personal information, diagnoses, and prescriptions were obtained from the Danish nationwide registries. Adjusted conditional logistic regression was used to investigate the association of RAO and RVO with the included risk factors. RESULTS RAO was stronger associated with arterial hypertension, heart failure, ischemic heart disease, peripheral artery disease, and stroke than RVO, with effect measures ranging from 1.10 to 2.21. RVO was associated with cataract and glaucoma with effect measures of 0.80 (95% CI 0.73-0.87) and 0.65 (95% CI 0.56-0.76), respectively. CONCLUSION Differences in the level of associations with the included risk factors suggests differences in the pathophysiologies of the two diseases. The main pathophysiology associated with RAO was atherosclerosis, whereas the main pathophysiology associated with RVO was changes in the pressure gradients of the eyes.

Abstract
Drug delivery to the suprachoroidal space (SCS®) has become a clinical reality after the 2021 FDA approval of CLS-TA, a triamcinolone acetonide injectable suspension for suprachoroidal use (XIPERE®), administered via a microneedle-based device, the SCS Microinjector®. Suprachoroidal (SC) delivery facilitates targeting, compartmentalization, and durability of small molecule suspensions, thereby potentially addressing some of the efficacy, safety, and treatment burden limitations of current retinal therapies. Herein, the design features of the SCS Microinjector are reviewed, along with the biomechanics of SC drug delivery. Also presented are preclinical evaluations of SC small molecule suspensions from 4 different therapeutic classes (plasma kallikrein inhibitor, receptor tyrosine kinase inhibitor, corticosteroid, complement factor D inhibitor), highlighting their potential for durability, targeted compartmentalization, and acceptable safety profiles following microinjector-based SC delivery. The clinical evaluations of the safety, tolerability and efficacy of SC delivered triamcinolone further supports potential of SC small molecule suspensions as a clinically viable strategy for the treatment of chorioretinal diseases. Also highlighted are current limitations, key pharmacological considerations, and future opportunities to optimize the SC microinjector platform for safe, effective, and potentially long-acting drug delivery for the treatment of chorioretinal disorders.

Abstract
PURPOSE The clinical practice visual acuity (VA) outcomes of anti-VEGF therapy for up to 5 years were assessed in patients with neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), branch retinal vein occlusion-related macular edema (BRVO-ME), and central retinal vein occlusion-related macular edema (CRVO-ME). DESIGN A retrospective analysis was performed using the Vestrum Health Retina Database. PARTICIPANTS Treatment-naive patients with nAMD, DME, BRVO-ME, or CRVO-ME who received anti-VEGF injections between 2014 and 2019 and had follow-up data for ≥12 months. METHODS Data on age, sex, the number of anti-VEGF treatments, and VA were analyzed. MAIN OUTCOME MEASURES Mean VA change up to 3 years (BRVO-ME and CRVO-ME) and 5 years (nAMD and DME). RESULTS At 1, 3, and 5 years, in 67 666, 21 305, and 5208 eyes with nAMD, after a mean of 7.6, 19.5, and 32 injections, there was a mean change of +3.1, -0.2, and -2.2 letters, respectively. At 1, 3, and 5 years, in 40 832, 7728, and 1192 eyes with DME, after a mean of 6.2, 15.4, and 26.0 injections, there was a mean change of +4.7, +3.3, and +3.1 letters, respectively. At 1 and 3 years, in 12 451 and 3027 eyes with BRVO-ME, after a mean of 7.1 and 18.2 injections, there was a mean change of +9.5 and +7.7 letters, respectively. At 1 and 3 years, in 9298 and 2264 eyes with CRVO-ME, after a mean of 7.3 and 18.8 injections, there was a mean change of +8.3 and +6.0 letters, respectively (P < 0.01 for all VA changes of > 1 letter). In all 4 conditions, the mean VA increased with the mean number of anti-VEGF injections, eyes with a baseline VA of 20/40 or better tended to lose VA, and eyes with progressively worse baseline VA experienced a progressively greater VA gain at 3 years. CONCLUSIONS In practice, patients with nAMD, DME, BRVO-ME, and CRVO-ME showed limited visual outcomes, with patients with nAMD tending to lose VA at 3 and 5 years. Across all 4 disorders, the mean change in VA correlated with treatment intensity at 1, 3, and 5 years. Patients with better baseline VA are more vulnerable to vision loss.

Month 60 Outcomes After Treatment Initiation With Anti-Vascular Endothelial Growth Factor Therapy for Macular Edema Due to Central Retinal or Hemiretinal Vein Occlusion. Am J Ophthalmol 2022; 240:330-341. [PMID: 35461831 PMCID: PMC11064059 DOI: 10.1016/j.ajo.2022.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 11/28/2022]
Abstract
PURPOSE To investigate 5-year outcomes in eyes initially treated with aflibercept or bevacizumab for macular edema due to central retinal or hemiretinal vein occlusion. METHODS Long-term follow-up (LTF) after a randomized clinical trial from 64 centers in the United States. Participants were followed up to 60 months and treated at investigator discretion after completing the 12-month treatment protocol. Main outcomes were visual acuity letter score (VALS) and central subfield thickness (CST) on optical coherence tomography. RESULTS Seventy-five percent (248/330) of eligible participants completed at least 1 visit between months 24 and 60, and 45% completed the month 60 visit. Among participants completing month 60, overall mean VALS improvement over baseline was 13.5 (95% CI: 9.6, 17.5), less than the mean improvement of 20.6 (95% CI: 18.7, 22.4) observed at month 12, with no significant differences between originally assigned study groups. Further, 66% (99/150) had at least 1 treatment between months 48 and 60 with a mean (SD) of 3.41 (3.69) treatments over this period. Mean CST was 671 μm at baseline and 261 μm (95% CI: 241.2, 280.9) at month 60. CONCLUSIONS Although VALS improved substantially when patients were treated per protocol through month 12, improvement lessened when treatment was at investigator discretion and fewer treatments were received although VALS remained markedly improved over baseline through year 5. Most patients continued to receive treatment in year 5. This suggests that continued monitoring and, if warranted, treatment with anti-VEGF therapy benefits patients with macular edema associated with central retinal or hemiretinal vein occlusion.

[PMID: 34974541 PMCID: PMC9151779 DOI: 10.1038/s41433-021-01766-w] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 08/19/2021] [Accepted: 09/07/2021] [Indexed: 12/26/2022] Open
Abstract
In the real-world setting, there is suboptimal compliance with treatments that require frequent administration and assessment visits. This undertreatment frequently has negative consequences in eye disease and carries a real risk to vision. For example, patients with glaucoma risk progression of visual loss even with a small number of missed doses, and patients with neovascular age-related degeneration (nAMD) who fail to attend a bi-monthly clinic appointment to receive an intravitreal anti-vascular endothelial growth factor (VEGF) drug injections may lose the initial vision gains in vision. Protracted regular treatment schedules represent a high burden not only for patients and families, but also healthcare professionals, systems, and ultimately society too. There has been a clear need for longer-acting therapies that reduce the frequency, and therefore the burden, of treatment interventions. Several longer-acting interventions for nAMD, diabetic macular oedema, retinal vein occlusion, uveitis and glaucoma have either been developed or are in late-phase development, some of which employ novel mechanisms of actions, and all of which of promise longer (≥3 month) treatment intervals. This review delivers an overview of anti-VEGF agents with longer durations of action, DARPins, bispecific anti-VEGF/Ang2 therapies, anti-PDGF and anti-integrin therapy, Rho-kinase inhibitors, the Port Delivery System, steroids, gene therapy for retina and uveitis, and for glaucoma, ROCK inhibitors, implants and plugs, and SLT laser and MIGS. The review also refers to the potential of artificial intelligence to tailor treatment efficacy with a resulting reduction in treatment burden.

Abstract
Purpose To compare 12‐month treatment outcomes of eyes receiving aflibercept or ranibizumab for macular oedema secondary to central retinal vein occlusion (CRVO) in routine clinical practice. Methods 296 treatment‐naïve eyes receiving either aflibercept (171 eyes, 2 mg) or ranibizumab (125 eyes, 0.5 mg) for macular oedema secondary to CRVO were recruited retrospectively from centres using the prospectively designed FRB! registry. The primary outcome measure was the mean change in LogMAR letter scores of visual acuity (VA). Secondary outcomes included change in central subfield thickness (CST), injections and visits, time to first grading of inactivity, switching and non‐completion from baseline to 12 months. Results Baseline VA (SD) was somewhat better in aflibercept‐ versus ranibizumab‐treated eyes (42.5 ± 25.5 letters versus 36.9 ± 26 letters; p = 0.07) with similar CST (614 (240) μm versus 616 (234) μm: p = 0.95). The 12‐month adjusted mean (95%CI) VA change was +16.6 (12.9, 20.4) letters for aflibercept versus +9.8 (5.5, 14.1) letters for ranibizumab (p = 0.001). The mean (95%CI) adjusted change in CST was significantly greater in aflibercept‐ versus ranibizumab‐treated eyes: −304 (−276, −333) µm versus −252 (−220, −282) µm (p < 0.001). Both groups had a median (Q1, Q3) of 7 (5, 9) injections and 10 (8,13) visits. Aflibercept‐treated eyes became inactive sooner than ranibizumab (p = 0.02). Switching occurred more commonly from ranibizumab (26 eyes, 21%) than from aflibercept (9 eyes, 5%) (p < 0.001). Conclusion Both aflibercept and ranibizumab improved VA and reduced CST in eyes with CRVO in routine clinical practice, with aflibercept showing significantly greater improvements in this comparative analysis.

Changes in 12-month outcomes over time for age-related macular degeneration, diabetic macular oedema and retinal vein occlusion. Eye (Lond) 2022; 37:1145-1154. [PMID: 35508721 PMCID: PMC9066999 DOI: 10.1038/s41433-022-02075-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 03/21/2022] [Accepted: 04/19/2022] [Indexed: 11/08/2022] Open
Abstract
Objectives To identify whether the outcomes of neovascular age-related macular degeneration (nAMD), diabetic macular oedema (DMO) and retinal vein occlusion (RVO) in routine clinical practice have changed over time. Methods We analysed 12-month outcomes in treatment-naïve eyes that started aflibercept or ranibizumab for nAMD (3802 eyes), DMO (975 eyes), Branch RVO (BRVO, 357 eyes), Central RVO (CRVO, 371 eyes) and Hemi-RVO (HRVO, 54 eyes) from 2015 and 2019 tracked in the prospectively designed observational Fight Retinal Blindness! Registry. Results The mean VA change at 12-month for each year between 2015 and 2019 remained stable or otherwise showed no discernible trends over time in eyes with nAMD (+3.3 to +6 letters), DMO (+3.6 to +6.7 letters) and RVO (+10.3 to +11.7 letters for BRVO, +5.9 to +17.7 letters for CRVO and 10.2 to 20.7 letters for HRVO). The median number of VEGF-inhibitor injections in eyes that completed 12-month follow-up also remained stable at 8–9 for nAMD, 6–7 for DMO, 7–9 for RVO. Fewer eyes (<one-fourth) that started treatment between 2015 and 2018 and more eyes starting in 2019 did not complete 12-month’s follow-up visit. The mean VA in non-completers at their last visit was higher than that of their baseline visit. Conclusions Treatment patterns and outcomes for nAMD, DMO and RVO in routine clinical practice have stabilised over the past 5 years at levels inferior to those reported by the pivotal phase 3 studies. A conscious effort to treat these conditions more intensively, or with longer lasting agents, would likely improve outcomes further in our patients.

The Efficacy of Simultaneous Injection of Dexamethasone Implant and Ranibizumab Into Vitreous Cavity on Macular Edema Secondary to Central Retinal Vein Occlusion. Front Pharmacol 2022; 13:842805. [PMID: 35300292 PMCID: PMC8921766 DOI: 10.3389/fphar.2022.842805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Accepted: 02/14/2022] [Indexed: 11/14/2022] Open
Abstract
The purpose of this study was to determine the safety and effectiveness of simultaneous vitreous injection of dexamethasone implant and ranibizumab on macular edema secondary to central retinal vein occlusion (CRVO). We conducted a 6-month retrospective self-control study. Twenty-five patients diagnosed with macular edema secondary to CRVO were enrolled in this study. The patients received intravitreal injection of dexamethasone implant and ranibizumab. The changes in best corrected visual acuity (BCVA), central retinal thickness (CRT) and interocular pressure (IOP) before and at 2w, 1, 2, 3, 4, 5, 6 m after injection were recorded and compared. The adverse reactions in eyes and whole body were observed. The BCVA of all patients at 2 w (61.8 ± 5.42), 1 m (68.68 ± 5.23), 2 m (70.8 ± 5.8), 3 m (68.44 ± 5.61), 4 m (65.76 ± 5.76), 5 m (67.08 ± 5.57), and 6 m (70.12 ± 5.46) after surgery were significantly higher than that before surgery (52.2 ± 5.06,p < 0.01), and CRT of all patients at 2w (393.36 ± 52.66 um), 1 m (334.52 ± 32.95 um), 2 m (298.800 ± 29.97 um), 3 m (309.080 ± 28.78 um), 4 m (345.48 ± 39.81 um), 5 m (349.080 ± 29.88 um), and 6 m (309.76 ± 30.41 um) after surgery were significantly reduced than that before surgery (583.76 ± 121.09 um, p < 0.01). Macular edema recurred in an average of 4.44 ± 0.51 months after treatment, and those patients received combined treatment again. During follow-up, the most common adverse reactions were subconjunctival hemorrhage and increased intraocular pressure, with the incidence of 22% (11/50) and 18% (9/50) respectively. In all cases, the increased intraocular pressure could be controlled by a single intraocular pressure reducing drug. No patient needed to receive anti-glaucoma surgery. The overall incidence of lens opacity was 4% (2/50). After the first injection, no case showed lens opacity. After re-injection, 2 patients (2 eyes) (8%) developed lens opacity. None of the patients showed serious ocular adverse reactions or systemic complications such as vitreous hemorrhage, retinal detachment, endophthalmitis, uveitis or ocular toxicity. The simultaneous vitreous injection of dexamethasone implant and ranibizumab can significantly improve the visual acuity and anatomical prognosis in macular edema secondary to central retinal vein occlusion (CRVO-ME) patients, exhibiting good safety and effectiveness.

Abstract
PURPOSE retinal vein occlusion (RVO) is classified as either branch (BRVO) or central (CRVO) RVO. The gold standard treatment for macular oedema (MO) secondary to RVO is intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections. Our study aimed to compare ranibizumab and aflibercept outcomes over a maximum follow-up of five years. METHODS this retrospective study assessed treatment-naïve RVO patients. Active disease was treated with three loading injections followed by a pro-re-nata (PRN) regimen of an anti-VEGF agent. Visual outcomes and injection frequency were analyzed, with patients stratified according to RVO subtype, anti-VEGF agent used, baseline vision, and age. RESULTS 316 CRVO-affected eyes and 467 BRVO-affected eyes were analysed. Visual benefits between different treatments did not significantly differ, except in year 1 in ranibizumab-treated BRVO eyes. However, aflibercept-treated CRVO and BRVO eyes required significantly fewer injections during the follow up period. Furthermore, our results confirm that younger patients achieve better visual outcomes with fewer intravitreal injections. Overall, half of our patients did not require further injections after 1 year from diagnosis. CONCLUSION the results demonstrate that anti-VEGF treatment of RVO benefits vision for up to 5 years. Our findings are the first to suggest that compared to ranibizumab, fewer aflibercept injections may be required over five years follow up. Prospective randomised trials are needed to confirm this, alongside further attention to OCT scan features and the effect of patient demographics on treatment outcomes.

Abstract
To explore the factors associated with best-corrected visual acuity (BCVA) after anti-vascular endothelial growth factor (anti-VEGF) treatment for macular edema secondary to central retinal vein occlusion (CRVO). We retrospectively reviewed the medical charts of 22 eyes of 22 treatment-naïve patients with CRVO diagnosed between September 2014 and December 2020. They received anti-VEGF treatment and follow-up for > 12 months. Mean patient age was 64.3 years; 13 (59.1%) were men. Eyes with baseline arm-to-retina (AR) time ≥ 16 s had better BCVA at 12 months (adjusted for baseline BCVA and age; B, − 0.658; 95% confidence interval − 1.058 to − 0.257; P = 0.003), greater mean BCVA change (P = 0.006), lower frequency of residual macular edema at 12 months (P = 0.026) and recurrent and/or unresolved macular edema during 12 months (P = 0.046), and higher frequency of reduction in central retinal thickness ≥ 150 μm at 1 and 12 months (both P = 0.046). Delayed AR time was associated with a better visual outcome and macular edema improvement in CRVO after anti-VEGF treatment regardless of initial BCVA and age. Our results may help understand the pathogenesis and predict the visual prognosis of patients before anti-VEGF therapy initiation.

Central retinal thickness changes and risk of neovascular glaucoma after intravitreal bevacizumab injection in patients with central retinal vein occlusion. Sci Rep 2022; 12:2051. [PMID: 35136171 PMCID: PMC8826410 DOI: 10.1038/s41598-022-06121-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2021] [Accepted: 01/19/2022] [Indexed: 11/25/2022] Open
Abstract
This retrospective study evaluated changes in the central retinal thickness (CRT) and the risk factors for neovascular glaucoma (NVG) after intravitreal bevacizumab injection under a pro re nata (PRN) regimen for macular oedema in 57 eyes with central retinal vein occlusion (CRVO). The clinical characteristics at the time of NVG diagnosis were assessed, and baseline and final clinical characteristics and mean CRT values at 1-, 3-, and 6-month follow-up evaluations were recorded. The incidence of NVG was 21.1%, with the neovascular group (12 eyes) showing poor baseline and final visual acuity, a higher incidence of baseline ischaemic-type CRVO and subretinal fluid, a higher mean CRT at the 1-month follow-up, and a higher number of intravitreal bevacizumab injections during the 6-month follow-up. Nine eyes with NVG (75%) showed a mean CRT < 300 μm at the time of diagnosis. An ischaemic CRVO and higher CRT at the 1-month follow-up were related to the development of NVG in the multivariate analysis. Thus, NVG development in CRVO patients treated with intravitreal bevacizumab injections was associated with an ischaemic CRVO and elevated CRT at the 1-month follow-up; PRN bevacizumab regimens based on CRT or control of macular oedema did not completely prevent NVG development.

Abstract
Background/aimsTo describe baseline characteristics and 12-month outcomes with vascular endothelial growth factor (VEGF) inhibitors of treatment-naïve hemiretinal vein occlusion (HRVO) compared with branch (BRVO) and central (CRVO) variants in routine clinical care.MethodsA database observational study recruited 79 HRVO eyes, 590 BRVO eyes and 344 CRVO eyes that initiated therapy over 10 years. The primary outcome was mean change in visual acuity (VA—letters read on a logarithm of minimal angle of resolution chart) at 12 months. Secondary outcomes included mean change in central subfield thickness (CST), injections and visits.ResultsAt baseline, mean VA in HRVO (53.8) was similar to CRVO (51.9; p=0.40) but lower than BRVO (59.4; p=0.009). HRVO eyes improved to match BRVO eyes from soon after treatment started through 12 months. Mean change in VA was greater in HRVO (+16.4) than both BRVO (+11.4; p=0.006) and CRVO (+8.5; p<0.001). Mean change in CST in HRVO (−231 µm) was similar to CRVO (−259 µm; p=0.33) but greater than BRVO eyes (−151 µm; p=0.003). The groups had similar median burdens of eight injections and nine visits.ConclusionsHRVO generally experienced the greatest mean change in VA of the three types of RVO when treated with VEGF inhibitors, ending with similar 12-month VA and CST to BRVO despite starting closer to CRVO. Inclusion of HRVO in BRVO or CRVO cohorts of clinical trials would be expected to proportionally inflate and skew the visual and anatomic outcomes.

Abstract
Purpose Determine the anatomical consequences of delaying intravitreal injection (IVI) therapy with anti-vascular endothelial growth factor (anti-VEGF) in patients using treat-and-extend (T&E) protocol. Methods Retrospective medical record review of consecutive patients receiving intravitreal anti-VEGF therapy using T&E protocol prior to and during the COVID-19 pandemic. Results The study included 923 eyes of 691patients; 58.8% (543 eyes), 25% (231 eyes), and 16.2% (149 eyes) had nvAMD, DME, and RVO, respectively. Mean (± SD) patient age was 74.5 ± 11.7 years. Overall, 56.3% of cases had a delay in therapy of ≥ 7 days; specifically, 56.2%, 61.5%, and 49.0% of nvAMD, DME, and RVO cases, respectively, had a delay. The median delay in days, among cases ≥ 7 days late was 21 (IQR 7 to 42) days, with 21(IQR 7 to 45), 22.5(IQR 8 to 42), and 14(IQR 7 to 33.5) days of delay among patients with nvAMD, DME, and RVO, respectively. Delaying therapy by ≥ 7 days resulted in increased CST in 47.5%, 58.5%, and 58.9% of nvAMD, DME, and RVO cases, respectively, with a significant correlation between the length of treatment delay and the increase in CST (Spearman’s rho: 0.196; p < 0.001). Conclusions Delayed IVI treatment in eyes treated with T&E protocol was associated with increased macular thickness with potential consequences with respect to visual outcome.

Abstract
AIM To present the case of a patient with myopic choroidal neovascular membrane (mCNV) in the 3rd trimester of pregnancy, who was treated with intravitreal ranibizumab. CASE REPORT The 34-year-old patient was referred to the Department of Ophthalmology of the University Hospital Kralovske Vinohrady in January 2020 for mCNV on her right eye (RE). The patient was in the 34th week of pregnancy. Initial best corrected visual acuity (BCVA) was 68 ETDRS letters. Spherical equivalent of the RE was -11.5 dioptres, axial length of the RE was 27.7 mm. Pigmented CNV with small haemorrhage was present on the retina of the RE. Optical coherence tomography (OCT) of the RE showed a hyperreflective mass above the retinal pigment epithelium, central retinal thickness (CRT) was 310 µm. OCT angiography confirmed the presence of a classic CNV in the macula of the RE. Two weeks later, the hyperreflective lesion and oedema in the macula of the RE increased, the CRT was 329 µm, BCVA remained stable. After discussion with the patient and the treating gynaecologist, intravitreal ranibizumab was administered in the RE in the 36th week of pregnancy. On check-up 3 weeks later, we observed the decrease of macular oedema to 276 µm and the improvement of BCVA to 78 ETDRS letters. The patient delivered a healthy baby girl in the 39th week of pregnancy via caesarean section, postnatal adaptation of the newborn was normal. During further visits, the BCVA improved to 83 ETDRS letters and the macular oedema disappeared completely. 8 months after the first ranibizumab injection, the CNV reactivated, BCVA decreased to 72 ETDRS letters, oedema was present in the macula and the CRT was 309 µm. Another ranibizumab was administered into the RE. The patient then discovered that she was pregnant; according to calculations, she was in the 3rd week of pregnancy at the time of the second ranibizumab injection. After the second injection, BCVA improved to 79 ETDRS letters, macular oedema on the OCT disappeared and CRT decreased to 264 µm. The pregnancy was terminated per patients request. CONCLUSION Intravitreal administration of ranibizumab in the 3rd trimester of pregnancy led to the improvement of BCVA and decrease of macular oedema in the patient with mCNV. The injection had no adverse effect on the pregnancy or the postnatal adaptation of the newborn. However, it is always necessary to consider the risk/benefit ratio when administering intravitreal antiVEGF drugs in pregnant patients. Thorough discussion with the patient is necessary.

Abstract
Purpose To report a case of combined central retinal vein and artery occlusion that evolved into ischemic optic neuropathy following the Pfizer COVID-19 vaccination. Methods Patient was followed with optical coherence tomography (OCT), fluorescein angiography, and Humphrey visual field. Results Patient was able to recover vision from count fingers to 20/30 on a combination of aflibercept, steroidal and non-steroidal anti-inflammatories, a diuretic (acetazolamide), antiplatelet agents (aspirin and pentoxifylline), and an anticoagulant (apixaban). Conclusion COVID-19 vaccination may be associated with a myriad of sight-threatening ocular thrombotic conditions, which may respond to a combination of anti-inflammatory and anticoagulant therapies.

Abstract
OBJECTIVE To investigate treat-and-extend (T&E) regimens of anti-vascular endothelial growth factor (anti-VEGF) therapy for the treatment of macular oedema secondary to retinal vein occlusions (RVOs). METHODS Ovid MEDLINE, Ovid EMBASE and CENTRAL were searched on 25 February 2021. Randomized controlled trials, cohort studies, case-control studies and case series were included. The primary outcome was the change in Early Treatment Diabetic Retinopathy Score (ETDRS) letters from baseline. Conversions from Snellen to ETDRS letters were performed utilizing a published protocol. Secondary outcomes included improvement in retinal thickness from baseline, number of anti-VEGF injections and frequency of adverse events. Outcomes were examined at 12 and 24 months. Certainty of evidence was assessed utilizing GRADE (Grading of Recommendations Assessments, Development and Evaluations) guidelines. RESULTS Seven hundred eighty-six eyes from 16 studies were included. Meta-analysis demonstrated a mean improvement of 15.7 (95% CI: 13.3-18.0) ETDRS letters at 12 months. Central retinal thickness improved 269.7 μm (95% CI: 233.64-305.90) at 12 months. Injections were performed 8.1 (95% CI: 7.4-8.7) and 13.1 (95% CI: 9.4-16.8) times at 12 and 24 months respectively. Adverse events were infrequent across all studies. Grading of Recommendations Assessments, Development and Evaluations (GRADE) certainty of evidence was very low across all outcomes. CONCLUSIONS The results support the viability of T&E regimens for the treatment of macular oedema secondary to RVOs.

Abstract
BACKGROUND/AIMS To assess the effectiveness, burden and safety of two categories of treatment for central retinal vein occlusion (CRVO): intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) and dexamethasone (Ozurdex). METHODS A retrospective analysis of Medisoft electronic medical record (EMR) data from 27 National Health Service sites in the UK identified 4626 treatment-naive patients with a single mode of treatment for macular oedema secondary to CRVO. Statistics describing the overall CRVO patient cohort and individual patient subpopulations stratified by treatment type were generated. Mean age at baseline, gender, ethnicity, social deprivation and visual acuity (VA) follow-up was reported. Absolute and change in VA using ETDRS are used to describe treatment effectiveness, the number of injections and visits used to describe treatment burden and endophthalmitis rates as a marker of treatment safety. RESULTS Mean VA was 47.9 and 45.3 EDTRS letters in the anti-VEGF and Ozurdex groups, respectively. This changed to 57.9/53.7 at 12 months, 58.3/46.9 at 18 months and 59.4/51.0 at 36 months. Mean number of injections were 5.6/1.6 at 12 months, 6.0/1.7 at 18 months and 7.0/1.8 at 36 months. Endophthalmitis rates were 0.003% (n=4) for the anti-VEGF group and 0.09% (n=1) for the Ozurdex group. CONCLUSIONS VA improvements were greater and more sustained with anti-VEGF treatment. Lower starting acuity resulted in bigger gains in both groups, while higher starting acuity resulted in higher VA at 36 months. Although treatment burden was greater with anti-VEGF, Ozurdex was associated with higher rates of endophthalmitis.

PURPOSE The purpose of this study was to report the 5-year outcomes of treatment-naive eyes with cystoid macular edema secondary to central retinal vein occlusion treated with intravitreal bevacizumab in routine clinical practice. METHODS We conducted multicenter retrospective non-comparative case series of 102 eyes. The main outcome measured was the change in best-corrected visual acuity (BCVA) at 5 years. Secondary outcomes included the number of injections and the change in CMT at 5 years. RESULTS At 5 years, the mean BCVA improved from 1.22 ± 0.58 (Snellen 20/428) at baseline to 1.00 ± 0.68 logMAR (Snellen 20/200; p < 0.0001). At 5 years, 48 (47%) eyes had a gain of ≥ 3 lines, 41 (40.2%) eyes remained within 3 lines and 13 (12.7%) eyes had a loss of ≥ 3 lines of BCVA. The CMT improved from 740 ± 243 to 322 ± 179 µm (p < 0.0001). At 5 years, 59 (57.8%) eyes had a completely dry SD-OCT. Patients received a total of 10.6 ± 6.1 (range 6-27) injections. Baseline BCVA (p < 0.0001) and the duration of symptoms prior to initial anti-VEGF injection (p = 0.0274) were the only predictive factors for BCVA at 5 years. CONCLUSIONS After 5 years with an average of 10.6 injections, there was a mean gain of 0.22 logMAR. In addition, more eyes achieved a BCVA of ≥ 20/40, gained ≥ 3 lines and less patients had a BCVA ≤ 20/200. Eyes with a better baseline BCVA and a shorter duration of symptoms were more likely to achieve better BCVA at 5 years.

Abstract
Increased angiogenesis and vascular endothelial growth factor (VEGF) levels contribute to higher metastasis and mortality in uveal melanoma (UM), an aggressive malignancy of the eye in adults. (±)-MRJF22, a prodrug of the sigma (σ) ligand haloperidol metabolite II conjugated with the histone deacetylase (HDAC) inhibitor valproic acid, has previously demonstrated a promising antiangiogenic activity. Herein, the asymmetric synthesis of (R)-(+)-MRJF22 and (S)-(-)-MRJF22 was performed to investigate their contribution to (±)-MRJF22 antiangiogenic effects in human retinal endothelial cells (HREC) and to assess their therapeutic potential in primary human uveal melanoma (UM) 92-1 cell line. While both enantiomers displayed almost identical capabilities to reduce cell viability than the racemic mixture, (S)-(-)-MRJF22 exhibited the highest antimigratory effects in endothelial and tumor cells. Given the fundamental contribution of cell motility to cancer progression, (S)-(-)-MRJF22 may represent a promising candidate for novel antimetastatic therapy in patients with UM.

[PMID: 34551746 PMCID: PMC8459492 DOI: 10.1186/s12886-021-02088-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 08/27/2021] [Indexed: 11/24/2022] Open
Abstract
Background The current study aimed to evaluate the efficacy of intravitreal aflibercept injections as the primary treatment for subfoveal/juxtafoveal myopic choroidal neovascularization (CNV) by using optical coherence tomography (OCT). Optical coherence tomography angiography (OCTA) was further used for some patients to detect the changes of CNV after treatment. Methods In the present study, 21 treatment-naive eyes of 21 patients with subfoveal/juxtafoveal myopic CNV received primary intravitreal aflibercept injections and were under follow-up for a minimum duration of 12 months. Among the 21 patients, 12 underwent OCTA to evaluate the changes in central foveal thickness, selected CNV area, and flow area. Results The mean best-corrected visual acuity (BCVA) pertaining to all the patients significantly improved from the baseline value of 0.7 to 0.3 logMAR after treatment for 12 months (P = 0.001). However, the improvements in the median BCVA after treatment for three and 12 months were not statistically significant in the younger group (< 50 years), compared to the older group (≥ 50 years). One aflibercept injection resolved the CNV in 47.6% (10/21) of the patients. The younger group displayed greater improvement in the median central foveal thickness, compared to the older group. OCTA revealed interlacing or disorganized pattern at the level of the outer retinal layer in 12 subjects with myopic CNV. After 3 months of treatment, both groups displayed a decrease in the size of the selected CNV area and flow area. The interlacing group displayed a trend towards better anatomical improvements. Conclusion Intravitreal aflibercept injection provides long-term improvement in visual acuity in patients with myopic CNV. Eyes with the interlacing pattern on OCTA displayed a greater decrease in size and flow after aflibercept injection. Trial registration Before data collection, written informed consent was obtained from each participant, whose identity information was protected by encryption and conversion to a non-identifiable format and removing data links. This study was approved by the Institutional Review Board of Kaohsiung Veterans General Hospital (KSVGH21-CT1–17).

Abstract
Aflibercept is a fully human recombinant fusion protein that includes the second domain of human VEGF receptor 1 and the third domain of human VEGF receptor 2. Despite the important role played by VEGF in maintaining the physiological condition of the retina under normal conditions, dysregulation of VEGF can result in pathological alterations including hyperpermeability of the retinal capillaries and migration and proliferation of retinal endothelial cells. Over the years, a number of studies have evaluated the use of intravitreal aflibercept in different retinal diseases. In this review, we aim to summarize the scientific evidence and recommendations for use of intravitreal aflibercept in neovascular age-related macular degeneration, diabetic macular oedema, macular oedema associated with retinal vein occlusion, and myopic choroidal neovascularization.
