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.

Twelve-month outcomes of ranibizumab versus aflibercept for macular oedema in branch retinal vein occlusion: data from the FRB! registry. Br J Ophthalmol 2021; 106:1178-1184. [PMID: 33712484 DOI: 10.1136/bjophthalmol-2020-318491] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Revised: 02/12/2021] [Accepted: 03/04/2021] [Indexed: 12/22/2022]
Abstract
BACKGROUND/AIMS To compare the efficacy of ranibizumab (0.5 mg) with aflibercept (2 mg) in the treatment of cystoid macular oedema due to branch retinal vein occlusion (BRVO) over 12 months. METHODS A multicentre, international, database observational study recruited 322 eyes initiating therapy in real-world practice over 5 years. The main outcome measure was mean change in EDTRS letter scores of visual acuity (VA). Secondary outcomes included anatomic outcomes, percentage of eyes with VA >6/12 (70 letters), number of injections and visits, time to first inactivity, switching or non-completion. RESULTS Generalised mixed effect models demonstrated that mean (95% CI) adjusted 12-month VA changes for ranibizumab and aflibercept were similar (+10.8 (8.2 to 13.4) vs +10.9 (8.3 to 13.5) letters, respectively, p=0.59). The mean adjusted change in central subfield thickness (CST) was greater for aflibercept than ranibizumab (-170 (-153 to -187) µm vs -147 (-130 to -164) µm, respectively, p=0.001). The overall median (Q1, Q3) of 7 (4, 8) injections and 9 (7, 11) visits was similar between treatment groups. First grading of inactivity occurred sooner with aflibercept (p=0.01). Switching was more common from ranibizumab (37 eyes, 23%) than from aflibercept (17 eyes, 11%; p=0.002). CONCLUSION Visual outcomes at 12 months in this direct comparison of ranibizumab and aflibercept for BRVO in real-world practice were generally good and similar for the 2 drugs, despite a greater effect of aflibercept on CST and time to first grading of inactivity.

A systematic review of real-world evidence of the management of macular oedema secondary to branch retinal vein occlusion. Eye (Lond) 2020; 34:1770-1796. [PMID: 32313172 PMCID: PMC7608462 DOI: 10.1038/s41433-020-0861-9] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2019] [Revised: 02/19/2020] [Accepted: 03/24/2020] [Indexed: 01/10/2023] Open
Abstract
This review assessed the real-world evidence of the management of macular oedema secondary to branch retinal vein occlusion (BRVO). A meta-analysis of 2530 eyes from 48 real-world studies of therapies for macular oedema secondary to BRVO was conducted. Baseline characteristics, visual, anatomical and safety outcomes were recorded. The weighted mean and weighted estimates from random-effects models were calculated for visual acuity (VA) and central subfield thickness (CST) changes at 6, 12 and 24 months. Primary outcome was change in VA (logMAR letters) at 12 months. Study quality was assessed using the quality appraisal checklist for case series developed by Institute of Health Economics. The mean baseline VA for the pooled data was 54.0 (51.5, 56.5) letters and the mean baseline CST was 501.3 (483.5, 519.1) µm. The random-effects estimate for mean (95% CI) change in VA was 14.6 (12.5, 16.7) letters at 12 months (n = 1727). The random-effects estimate for mean (95% CI) change in CST was -181.7 (-230.7, -132.7) µm at 12 months (n = 1325). The quality of studies varied considerably. Ocular and systemic adverse events were discussed in 79% and 42% of treatment arms respectively, with possible under-reporting. Visual and anatomical gains achieved in the real-world for anti-VEGF therapy were not as impressive as seminal RCTs, possibly due to reduced injection frequency in the real world and differences in baseline characteristics. There is an urgent need for consensus on the minimum efficacy, treatment burden and safety data to collect to strengthen the real-world evidence base.

Abstract
Purpose The non-interventional OCEAN study (NCT02194803) evaluated frequency and monitoring of ranibizumab injections for retinal vein occlusion (RVO) in routine practice in Germany. Methods RVO patients (including branch and central RVO (BRVO/CRVO)) receiving ranibizumab were included. Best-corrected visual acuity (BCVA) testing, imaging and treatment were performed at the investigators’ discretion and documented over 24 months. Results Overall, 744 RVO patients (27% BRVO, 16% CRVO, remaining unspecified RVO) were included. For 74% of patients, data were available for the 12-month visit and for 56% for the 24-month visit. Mean baseline BCVA was 52.0 Early Treatment for Diabetic Retinopathy Study (ETDRS) letters (BRVO: 55.9, CRVO: 43.9). BCVA improved rapidly within the first 3 months, reaching 64.3 letters at 12 months and 64.7 at 24 months. CRVO patients showed less improvement than those with BRVO. Patients received a median of 4 (5) injections over 12 (24) months, with 100% of patients receiving injections at baseline, 70% at Month 1 and 81% at Month 2. Overall, 40% of patients demonstrated a ≥15 letter increase within the first 3 months (42% BRVO, 46% CRVO). Patients with low initial BCVA (<50 letters) showed greater improvement than patients with higher baseline BCVA. Due to considerable loss to follow-up, the number of injections and optical coherence tomography (OCT) examinations were not associated with the change in BCVA. Conclusion Patients with RVO in routine practice in Germany received fewer injections and fewer OCT examinations than in clinical trials. CRVO patients showed less and later improvement compared to BRVO patients.

Prospective study of aflibercept for the treatment of persistent macular oedema secondary to retinal vein occlusions in eyes not responsive to long-term treatment with bevacizumab or ranibizumab. Clin Exp Ophthalmol 2019; 48:53-60. [PMID: 31498950 DOI: 10.1111/ceo.13636] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2019] [Revised: 08/28/2019] [Accepted: 09/02/2019] [Indexed: 11/27/2022]
Abstract
IMPORTANCE To examine the effect of switching from intravitreal bevacizumab or ranibizumab to aflibercept in eyes with persistent macular oedema due to retinal vein occlusion (RVO). BACKGROUND We report the results of a prospective interventional study on the effect of aflibercept 2 mg in eyes with persistent macular oedema after long-term treatment with bevacizumab or ranibizumab. DESIGN Non-randomized, prospective clinical trial. PARTICIPANTS Eighteen eyes of eighteen patients were included. METHODS Eyes with persistent macular oedema despite a minimum of four previous intravitreal bevacizumab/ranibizumab injections were recruited into this 48-week trial. Three loading doses of intravitreal aflibercept were administered every 4-weeks, thereafter every 8-weeks until week 48. MAIN OUTCOME MEASURES Mean change from baseline in best corrected visual acuity (BCVA) as measured by early treatment diabetic retinopathy score (ETDRS) and central macular thickness (CMT) as measured by spectral domain optical coherence tomography (SD-OCT) at 48 weeks. RESULTS Patients had received a mean of 40.0 ± 17.8 bevacizumab/ranibizumab intravitreal injections prior to switching to aflibercept. The mean number of previous injections administered in the 12-months preceding entry into the study was 10.2 ± 2.4. Mean vision change at week 48 was +21.1 ± 5.1 ETDRS letters in the BRVO group and +18.8 ± 5.9 letters at in the CRVO group (P < .001 for both groups). Mean decrease in CMT was 87.6 ± 48.8 μm and 191.0 ± 128.3 μm, in the BRVO and CRVO groups, respectively (P < .001). Using linear regression analyses, a higher number of previous intravitreal ranibizumab/bevacizumab injections and thicker pre-switch CMT were correlated with greater visual gains. CONCLUSION AND RELEVANCE Switching to aflibercept from bevacizumab or ranibizumab in eyes with persistent macular oedema due to RVO can lead to functional and anatomical improvement. This effect was more obvious in eyes with a greater CMT prior to the switch.

Abstract
PURPOSE The current body of evidence on the efficacy and safety of anti-VEGFs for macular oedema secondary to branch retinal vein occlusion (BRVO) is steadily growing as large clinical trials and observational studies are continually completed. The aim of this meta-analysis is to analyse anatomical and functional outcomes in response to anti-VEGF therapy using evidence generated from a pooled analysis of current clinical trials and observational studies. METHODS The current meta-analysis includes treatment of BRVO with aflibercept, bevacizumab and ranibizumab from randomised controlled trials and observational studies. Inclusion criteria included peer-reviewed publications with at least a 12-month follow-up period. On literature review using multiple electronic databases (PubMed, Embase and Cochrane), 22 studies met the inclusion criteria. Baseline patient characteristics, study design, sample size and 12- and 24-month change in best corrected visual acuity (BCVA) and central foveal thickness (CFT) as measured on optical coherence tomography imaging were pooled in a meta-analysis. Data were then stratified by study design and anti-VEGF therapy in subgroup analyses. RESULTS A total of 1,236 eyes from 22 studies were included in this meta-analysis. Mean baseline BCVA ranged from 66 ETDRS letters (20/50 Snellen equivalent) to 35 letters (20/200 Snellen). Mean baseline CFT ranged from 406.0 to 681.0 µm. Anti-VEGF treatment demonstrated an overall mean improvement in BCVA at 12 months of 14 letters (95% CI 12.0 to 16.2, p < 0.001) and CFT reduction of 228 µm (95% CI -278.9 to -176.1, p < 0.001). The BCVA gains at 12 months were maintained to month 24 with a mean gain of 12.5 letters (95% CI 6.3 to 18.8, p < 0.001), as well as reduction of CFT of 238 µm (95% CI -336.0 to -140.2, p < 0.001). No cases of endophthalmitis or glaucoma were reported in any study. CONCLUSION This meta-analysis confirms the comparable safety and efficacy of anti-VEGF therapies for patients with cystoid macular oedema secondary to BRVO. There is a need for randomised prospective comparative trials of anti-VEGF agents for BRVO.

Abstract
Purpose The purpose of this study was to determine the long-term outcomes of intravitreal bevacizumab (IVB) or intravitreal tissue plasminogen activator (tPA) or vitrectomy for macular edema associated with a branch retinal vein occlusion (BRVO). Methods This was a retrospective, interventional case series. Forty-one patients received a single 1.25 mg of IVB injection and followed by pro re nata protocol, 71 patients received a single intravitreal tPA, and 116 patients underwent phacovitrectomy with intraocular lens implantation. Results The baseline characteristics and follow-up periods were not significantly different among the three groups. The mean follow-up period was 55.5 months with a range of 12-160 months. Sixteen patients (39.0%) in the IVB group, 24 patients (33.8%) in the tPA group, and two patients (1.7%) in the vitrectomy group underwent additional surgeries during the follow-up period. The best-corrected visual acuity (BCVA) significantly improved in all groups at 1 year after the initial treatment (all, P<0.0001) and at the final visit (all, P<0.0001). The differences in the BCVA between the three groups were not significant at all times after the initial treatment. Conclusion The three groups led to similar long-term good visual outcomes. However, additional surgeries were performed in more than 30% of patients in the IVB and tPA groups.

Abstract
Purpose Report 5-year outcomes of patients receiving anti-vascular endothelial growth factor (VEGF) for the treatment of macular oedema secondary to retinal vein occlusion (RVO. Methods Retrospective review of eyes with RVO which initiated anti-VEGF treatment. Data including age, gender, visual acuity (VA) and injection numbers were obtained from medical records. Optical coherence tomography scans were graded for presence or absence of macular oedema and central foveal thickness (CFT). Macular perfusion was assessed on fundus fluorescein angiography by masked graders. Results 68 eyes (31 branch RVO, BRVO; 35 central RVO, CRVO and 2 hemi-RVO) with 5 years of follow-up after initiation of anti-VEGF treatment. Mean change in VA at 5 years was + 9.6 ± 21.6 letters among CRVO eyes and + 14.2 ± 15.6 letters among eyes with BRVO (p=0.001). Vision of 20/40 or better was achieved in 65 % of treated eyes. The proportion of eyes with a three-line improvement of vision (15 letters) at 5 years was 22 %. Mean CFT decreased by 257.6 ± 249.8 µm in eyes with CRVO and 145.6 ± 143.3 µm in eyes with BRVO. Conclusion The results confirm good long-term outcomes can be achieved with anti-VEGF therapy for RVO.

Abstract
To systematically review anatomical and functional outcomes of switching therapy from bevacizumab and/or ranibizumab to aflibercept in patients with persistent macular oedema secondary to retinal vein occlusions (RVO). A systematic search of aflibercept for the treatment of persistent macular oedema secondary to branch and central RVO was performed in EMBASE, PubMed and Cochrane databases prior to June 2017. The main outcome variables described were best-corrected visual acuity (BCVA) and central macular thickness (CMT). All results were analysed and pooled using random-effects models with 95% confidence intervals (CI). Eight studies met the inclusion criteria with a total of 137 eyes, incorporating both branch and central RVO. Meta-analysis demonstrated a nonsignificant change in BCVA at 6 and 12 months following switch to aflibercept (4.40 letters, 95% CI: -3.10 to 11.90, p = 0.25 and 3.10 letters, 95% CI: -1.74 to 7.94, p = 0.21, respectively). Significant improvement in mean CMT was observed after switch to aflibercept at 6 (-256.00 μm, 95% CI: -318.00 to -194.00, p < 0.001) but not 12 months (-118.00 μm, 95% CI: -261.00 to 25.00, p = 0.11). Switching from bevacizumab/ranibizumab to aflibercept may improve persistent macular oedema secondary to RVO. However, there may be a limitation in the potential of visual recovery.

Abstract
Purpose To evaluate the efficacy, safety, and injection frequency of vascular endothelial growth factor (VEGF) antagonists in the treatment of macular edema secondary to retinal vein occlusion (RVO) in clinical practice. Patients and methods A multicenter retrospective study of the medical records of 165 patients (95 branch RVO, 70 central RVO) treated with at least three anti-VEGF injections in the study eye was conducted. Available data collected for at least 6 months after the first injection included Snellen best-corrected visual acuity (BCVA), central retinal thickness (CRT) by time-domain optical coherence tomography (TD-OCT) or spectral-domain optical coherence tomography (SD-OCT), anti-VEGF injections, other treatments/procedures for RVO, and adverse events. Results At baseline prior to anti-VEGF treatment, mean BCVA was 20/80 Snellen equivalent and mean CRT was 499 μm. Mean number of anti-VEGF injections received was 7.1 during the first year, 5.4 during the second year, and 5.9 during the third year; 51.3% (842/1,641) of injections were ranibizumab, 44.1% (724/1,641) were bevacizumab, and 4.6% (75/1,641) were aflibercept. One in five patients received concomitant focal laser treatment. The percentage of patients achieving both BCVA of 20/40 or better and CRT ≤250 μm on TD-OCT or ≤300 μm on SD-OCT at the same visit (primary endpoint) was 26.1% (30/115) after the first anti-VEGF injection and ranged from 20.0% (7/35) to 36.7% (11/30) after the first 16 injections. After each anti-VEGF injection from the 1st to the 16th, <60% of patients achieved 20/40 or better BCVA and ≤70% of patients achieved CRT ≤250 μm on TD-OCT or ≤300 μm on SD-OCT. The most common treatment-related adverse event was blurry or cloudy vision. Conclusion In this real-world study, a mean of five to seven anti-VEGF injections was administered yearly, and the response to anti-VEGF therapy was suboptimal in many patients. Anti-VEGF therapy was well tolerated.
