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
OBJECTIVE Aim: To assess the effectiveness and safety of the proposed surgical technique for treating secondary neovascular glaucoma. PATIENTS AND METHODS Materials and Methods: We examined 28 eyes of 28 patients (16 women and 12 men), aged 46}7,2 years, with secondary neovascular glaucoma. All patients underwent a comprehensive ophthalmological examination before and during treatment. Two-stage treatment was applied to all patients. At the first stage - performed an advanced technique of non-penetrating deep sclerectomy while administering anti-VEGF (anti-vascular endothelial growth factor) intravitreal or intracameral injections. At the second - we performed externalization of Schlemm's canal followed by YAG laser trabeculectomy. Statistical analysis of the results was used the SPSS v. 11.0, MedStat v.15.1 software package for medical and biological research. RESULTS Results: The proposed surgical technique, leads to a gradual decrease in intraocular pressure (IOP) and regression of the iris and anterior chamber angle neovascularization. The postoperative course was uneventful for all the patients. In the early postoperative period, the IOP was observed to be normalized in all the eyes. The IOP ranged from 12 to 16 mm Hg. The neovascularization regression occurred (in 100 % of cases) within 5-7 days. CONCLUSION Conclusions: Gradual reduction of IOP reduces intraoperative complications. Intravitreal or intracameral injections of anti-proliferative agents contribute to the regression of neovascularization and further gradual reduction of IOP. Performing a laser trabeculectomy in the area where a non-penetrating deep sclerectomy was previously performed creates new pathways for the outflow of intraocular fluid from the anterior chamber and reduces the risks of reintervention.

Abstract
BACKGROUND Vascular endothelial growth factor inhibitors (VEGFi) have transformed the treatment of many retinal diseases, including diabetic maculopathy. Increasing evidence supports systemic absorption of intravitreal VEGFi and development of significant cardiorenal side effects. METHODS Systematic review and meta-analysis (PROSPERO: CRD42020189037) of randomised controlled trials of intravitreal VEGFi treatments (bevacizumab, ranibizumab and aflibercept) for any eye disease. Outcomes of interest were cardiorenal side effects (hypertension, proteinuria, kidney function decline and heart failure). Fixed-effects meta-analyses were conducted where possible. RESULTS There were 78 trials (81 comparisons; 13 175 participants) that met criteria for inclusion: 47% were trials in diabetic eye disease. Hypertension (29 trials; 8570 participants) was equally common in VEGFi and control groups (7.3 versus 5.4%; RR 1.08 [0.91; 1.28]). New or worsening heart failure (10 trials; 3384 participants) had similar incidence in VEGFi and control groups (RR 1.03 [0.70; 1.51]). Proteinuria (5 trials; 1902 participants) was detectable in some VEGFi-treated participants (0.2%) but not controls (0.0%; RR 4.43 [0.49; 40.0]). Kidney function decline (9 trials; 3471 participants) was similar in VEGFi and control groups. In participants with diabetic eye disease, risk of all-cause mortality was higher in VEGFi-treated participants (RR 1.62 [1.04; 2.46]). CONCLUSION In trials of intravitreal VEGFi, we did not identify an increased risk of cardiorenal outcomes, though these outcomes were reported in only a minority of cases. There was an increased risk of death in VEGFi-treated participants with diabetic eye disease. Additional scrutiny of post-licensing observational data may improve recognition of safety concerns in VEGFi-treated patients.

Abstract
PURPOSE To quantify stereopsis and other visual functions in patients with unilateral branch retinal vein occlusion (BRVO) and to investigate vision-related parameters that affect stereopsis. DESIGN Prospective observational study. SUBJECTS Forty-five patients undergoing intravitreal ranibizumab (IVR) treatment for unilateral BRVO. METHODS We examined stereopsis using the Titmus stereo test (TST) and TNO stereotest (TNO), best corrected visual acuity (BCVA), letter contrast sensitivity, severity of metamorphopsia and degree of aniseikonia before and 6 months after IVR. MAIN OUTCOME MEASURES Visual functions that affect stereopsis. RESULTS Baseline stereopsis in patients with BRVO was 2.7 ± 0.6 (range, 1.6-3.5) in the TST and 2.8 ± 0.5 (range, 1.8-3.3) in TNO. TST and TNO scores were significantly correlated with BCVA and letter contrast sensitivity at baseline (P < 0.001) but not with other visual functions. IVR treatment significantly improved stereopsis, BCVA, and letter contrast sensitivity. After treatment, TST scores were significantly correlated with BCVA (P < 0.001), letter contrast sensitivity (P < 0.001), and aniseikonia (P < 0.01). TNO scores were significantly correlated with BCVA (P < 0.01) and letter contrast sensitivity (P < 0.01). TST and TNO scores after treatment were significantly correlated with BCVA at baseline (P < 0.01 for both). CONCLUSIONS Deterioration of stereopsis in patients with BRVO was associated with changes in visual acuity and contrast sensitivity after treatment. Initial visual acuity is a prognostic factor for posttreatment stereopsis.

Front Pharmacol 2021; 12:752048. [PMID: 34955825 PMCID: PMC8692786 DOI: 10.3389/fphar.2021.752048] [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: 08/02/2021] [Accepted: 11/17/2021] [Indexed: 02/05/2023] Open
Abstract
Purpose: This network meta-analysis was conducted to obtain the relative effectiveness of different pharmacotherapy of macular edema secondary to retinal vein occlusion (RVO) by summarizing all available evidences. Methods: PubMed, Embase, and Cochrane Library databases were searched for all relevant randomized controlled trials. The outcomes were estimated through a network meta-analysis, including the mean change in best-corrected visual acuity (BCVA) from baseline, the proportion of patients who gained ≥15 letters in BCVA from baseline, the mean change in central retinal thickness (CRT). Results: We identified 15 randomized controlled trials (RCTs) involving 3,431 patients with RVO in our study. Different therapeutic regimens were compared including three anti-vascular endothelial growth factor (VEGF) agents (ranibizumab, bevacizumab, and aflibercept), ranibizumab with laser, dexamethasone intravitreal implant, and laser. For branch RVO, ranibizumab 0.5 mg monthly [weighted mean difference (WMD) = 11, 95% confidence intervals (CrI) 3.6 to 19], ranibizumab 0.5 mg 3 + pro re nata (WMD = 9.4, 95% CrI 0.43–18) is most effective in terms of changes of BCVA and 15 letters or more of BCVA improvement. For central RVO, three anti-VEGF regimens can improve visual acuity and there is no significant difference of efficacy among ranibizumab, bevacizumab and aflibercept (p > 0.05). Ranibizumab 0.5 mg monthly could achieve additional efficacy in CRT reduction in eyes with branch RVO or central RVO (WMD = -130, 95% CrI -400 to 140 or WMD = -280, 95% CrI -590 to 16)). Dexamethasone intravitreal implant (WMD = 1.7, 95% CrI -4.2 to 7.1 or WMD = 0.38, 95% CrI -9.8 to 8.8)) did not show a significant improvement in visual acuity at the end of 6 months follow-up in eyes with branch RVO or central RVO. Conclusion: In summary, this network meta-analysis demonstrated several anti-VEGF agents had equivalent effects on mean visual acuity changes and anatomical recovery in 6 months in eyes with branch or central RVO. Only one injection of dexamethasone intravitreal implant in 6 months could not maintain the visual benefit. Patients and clinicians could choose pharmacotherapies with further consideration toward personal factors.

Visual acuity after intravitreal ranibizumab with and without laser therapy in the treatment of macular edema due to branch retinal vein occlusion: a 12-month retrospective analysis. Int J Ophthalmol 2021; 14:1565-1570.

Abstract
AIM To identify factors contributing to visual improvement after treatment of macular edema (ME) secondary to branch retinal vein occlusion (BRVO), and to assess the interaction between laser therapy and intravitreal ranibizumab (IVR). METHODS We retrospectively reviewed the medical records of patients who had been treated for BRVO-related ME at our hospital. Records were traceable for at least 12mo, and evaluated factors included age, sex, medical history, smoking history, treatment methods, foveal hemorrhage, and change in visual acuity. Treatments included laser therapy, IVR, sub-Tenon's capsule injection of triamcinolone (STTA), a combination, or no intervention. Multivariate logistic regression analysis and interaction terms were used to assess the clinical efficacy of the treatments, and odds ratios (OR) and 95% confidence intervals (CI) were calculated. RESULTS Seventy-three patients (34 men, 39 women; 73 eyes) with a mean age of 69.4±12.1y were included. Patients who underwent IVR monotherapy, laser monotherapy, and STTA+laser had significantly higher best corrected visual acuity at 12mo compared to baseline (P<0.001, <0.001, and 0.019, respectively). Logistic regression analysis without interaction terms found that IVR was a significant visual acuity recovery factor (adjusted OR: 3.89, 95%CI: 1.25-12.1, P=0.019). Adjusted OR using an interaction model by logistic regression was 16.6 (95%CI: 2.54-108.47, P=0.003) with IVR treatment, and 8.25 (95%CI: 1.34-50.57, P=0.023) with laser treatment. No interaction was observed (adjusted OR: 0.07, 95%CI: 0.01-0.75, P=0.029). CONCLUSION IVR contributes to improvements in visual acuity at 12mo in ME secondary to BRVO. No interaction is observed between laser therapy and IVR treatments.

Abstract
PURPOSE To quantify aniseikonia following intravitreal ranibizumab (IVR) in patients with branch retinal vein occlusion (BRVO) and assess the relationship between aniseikonia and retinal microstructure. STUDY DESIGN Prospective observational study. METHODS This study included 50 patients undergoing IVR treatment for unilateral BRVO. The degree of aniseikonia and best-corrected visual acuity (BCVA) was examined, and retinal microstructure was assessed with optical coherence tomography (OCT) before and 1, 2, 3, 4, 5, and 6 months after treatment. Based on OCT images, we assessed central retinal thickness (CRT), presence of the epiretinal membrane, and serous retinal detachment (SRD), as well as status of the external limiting membrane and ellipsoid zone. RESULTS At baseline, mean aniseikonia was - 1.0 ± 2.5%, ranging from - 11.0 to + 6.0%. Nine out of 50 patients had micropsia (18%), one had macropsia (2%), and 40 had no aniseikonia (80%). After 6 months of treatment, mean aniseikonia was - 0.7 ± 1.5%, ranging from - 4.5 to + 3.5%. BCVA significantly improved after treatment (P < 0.001), but aniseikonia did not change (P = 0.73). In patients with BRVO who had micropsia (≤ - 2.0%) at baseline, mean aniseikonia significantly improved from - 4.8 ± 3.3% to - 0.9 ± 1.4% (P < 0.05). Aniseikonia after treatment significantly correlated with BCVA (P < 0.05) and the presence of SRD at baseline (P < 0.05). CONCLUSION Majority of eyes with aniseikonia in BRVO had micropsia. The BCVA as well as the micropsia improved following treatment with IVR for BRVO. BCVA and the presence of SRD were predictors of post-treatment aniseikonia.

Abstract
IMPORTANCE Systemic safety of intravitreal anti-vascular endothelial growth factor (anti-VEGF) is a matter of debate and regular updates are necessary. OBJECTIVE To evaluate systemic adverse events (SAEs) associated with intravitreal anti-VEGF drugs compared with non-anti-VEGF treatments in patients with ocular diseases. DATA SOURCES Electronic searches were conducted in MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases from inception to July 7, 2020. STUDY SELECTION Randomized clinical trials conducted in adults with retinal diseases who received intravitreal anti-VEGF drugs. DATA EXTRACTION AND SYNTHESIS Studies and treatment characteristics and outcome data were extracted and analyzed, and study quality was evaluated. MAIN OUTCOMES AND MEASURES Main outcomes were major cardiovascular events (MACEs) and total mortality. Secondary outcomes included nonocular hemorrhage, components of MACEs, other cardiovascular outcomes, serious SAEs, and all SAEs. RESULTS A total of 74 randomized clinical trials were analyzed: 32 trials (43%) included 14 190 patients with age-related macular degeneration (AMD), 24 (32%) included 5424 patients with diabetic retinopathy (diabetic macular edema or proliferative diabetic retinopathy), 17 trials (23%) included 3757 patients with retinal vein occlusion, and 1 trial (1%) included 122 patients with myopic choroidal neovascularization. Anti-VEGF drug administration did not increase MACEs compared with control agents (odds ratio [OR], 1.16; 95% CI, 0.85-1.58) or total mortality (OR, 1.27; 95% CI, 0.82-1.96). There was an interaction (subgroup difference, P = .04) in mortality risk depending on the underlying disease with an increase (OR, 1.80; 95% CI, 1.03-3.16; P = .04) in the risk of death in patients with diabetic retinopathy; however, no increase was observed in patients with AMD or retinal vein occlusion. Administration of anti-VEGF drugs increased the risk of nonocular hemorrhage (OR, 1.46; 95% CI, 1.01-2.10), mainly in patients with AMD. CONCLUSIONS AND RELEVANCE Intravitreal anti-VEGF was not associated with an increase in MACEs in the trials examined herein. Increased mortality in patients with diabetes and nonocular hemorrhages, especially in those with AMD, could represent a safety signal, but the evidence was not strong. However, continued surveillance of SAEs remains warranted.

Abstract
Background: To evaluate the longitudinal changes on optical coherence tomography angiography (OCTA) in retinal vein occlusion (RVO). Methods: Retrospective study of patients with RVO treated with intravitreal anti-vascular endothelial growth factors (VEGF) for macular edema. Foveal avascular zone (FAZ) area, vessel density (VD), vessel length density (VLD), and adjusted flow index (AFI) were calculated. The unaffected eye of each participant was used as a control. Results: Twelve RVO eyes were included, receiving 6 ± 3 anti-VEGF injections over a follow-up of 10.4 ± 3.1 months. Compared to fellow eyes, RVO eyes had lower VD and VLD at inclusion (p = 0.07 and p = 0.04) and last visit (p = 0.002 and p < 0.001). VD, AFI, and VLD did not change over time, while FAZ area increased in RVO eyes (+0.016 ± 0.024 mm2, p = 0.04). AFI correlated with duration of disease (r = 0.63, p = 0.02). Visual acuity was inversely related to VD and VLD over the follow-up. Conclusions: OCTA parameters remained stable with sustained anti-VEGF treatment in RVO, while changes in the FAZ area may suggest capillary remodeling after RVO.

Hayreh SS. Photocoagulation for retinal vein occlusion. Prog Retin Eye Res 2021; 85:100964. [PMID: 33713810 DOI: 10.1016/j.preteyeres.2021.100964] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 03/03/2021] [Accepted: 03/04/2021] [Indexed: 10/21/2022]
Abstract
The role of photocoagulation in retinal vein occlusion (RVO) has been studied since 1974. The most serious complications of central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO) are: (i) visual deterioration, most commonly due to macular edema, and (ii) the development of ocular neovascularization (NV), particularly neovascular glaucoma (NVG), with hazardous consequences for vision and even the eye itself. Before discussing the role of photocoagulation in the management of NV and macular edema in RVO, it is crucial to gain a basic scientific understanding of the following relevant issues: classification of RVO, ocular NV in RVO, and the natural history of macular edema and visual outcome of RVO. These topics are discussed. In CRVO, ocular NV is a complication of ischemic CRVO but not of nonischemic CRVO. Photocoagulation has been advocated to prevent and/or treat the development of ocular NV and NVG. Since NVG is the most dreaded, intractable and blinding complication of ischemic CRVO, the role of photocoagulation and its management are discussed. Findings of three randomized, prospective clinical trials dealing with photocoagulation in ischemic CRVO are discussed. The role of photocoagulation in the management of ocular NV and macular edema in BRVO, and three randomized, prospective clinical trials dealing with those are discussed. Recent advent of intravitreal anti-VEGF and corticosteroid therapies has drastically changed the role of photocoagulation in the management of macular edema and NV in CRVO and BRVO. This is discussed in detail.

Abstract
Background Macular edema secondary to retinal vein occlusion (RVO) is an important cause of loss of vision. Intravitreal injections (IVI) of anti-vascular endothelial growth factor (VEGF) are the standard of care in this disease, as shown in numerous randomized controlled trials. The purpose of this study was to study the efficacy and safety of ranibizumab, an anti-VEGF agent, in the real-world setting. Methods This was 48 weeks, open-label, prospective, multicentre, observational study. Patients diagnosed with ME secondary to RVO were treated with IVI of Ranibizumab 0.5 mg in real-world conditions. Efficacy was measured by improvement seen in best-corrected visual acuity (BCVA) in terms of Early Treatment of Diabetic Retinopathy Study (ETDRS) Letter Scores and change in central retinal thickness (CRT) measured by optical coherence tomography. Results One hundred eyes of 100 patients (79 with branch retinal vein occlusion and 21 with central retinal vein occlusion) were recruited in the study. The mean (standard deviation, SD) BCVA was 52.8 (21.99) letters at baseline and 62.3 (24.40) letters at week 48. From baseline, there was a significant improvement in BCVA by 7.7 letters (p = 0.001) at 48 weeks. The mean (SD) of CRT was 479.9 (216.25) μm at baseline and it decreased significantly to 284.9 (171.35) μm at week 48 (p < 0.001). During the study period, the average number of intravitreal injections was 3.5 per patient. There was no report of endophthalmitis in any eye. Conclusions Ranibizumab is well tolerated and effective in treating macular edema secondary to RVO in real-world clinical settings. However, there is under-treatment compared to controlled clinical trials, and the gain in vision is sub-optimal with under-treatment.

Abstract
INTRODUCTION The role of vascular endothelial growth factor in macular edema (ME) due to branch retinal vein occlusion (BRVO) by enhancing vascular permeability has been well studied. ME due to BRVO often recurs; however, there has been no report on the relationship between this recurrence and choroidal thickness (CT), considering the high vascularity of the choroid. This study was designed to investigate this relationship. METHODS In this retrospective consecutive case series, patients with recurrence of ME within 6 months of receiving intravitreal aflibercept injection treatment for naive ME due to BRVO at Juntendo University Urayasu Hospital were included. Retinal thickness (RT) and CT were measured in the fovea and on the occlusion, non-occlusion, nasal, and temporal sides at baseline, after the first intravitreal aflibercept administration, and before and after recurrence. We also examined the change for each side before and after reinjection. RESULTS This study included 11 patients and 11 eyes. The subfoveal CT and RT at baseline were 261.9 ± 93.4 μm and 691.5 ± 254.4 μm, respectively, which significantly decreased to 208.5 ± 70.3 μm and 188.6 ± 33.8 μm, respectively, at 1 month after the first injection (p = 0.001 and p < 0.01, respectively). These values also significantly decreased at all the other sites after treatment. There were 14 recurrences within the 6 months following intravitreal aflibercept injection; RT significantly changed at all sites before and after recurrence and reinjection. CT significantly changed at the subfovea and on the occlusion and non-occlusion sides; however, there was no significant change on the nasal and temporal sides. CONCLUSION In patients with BRVO, the CT around the macula after initial treatment was significantly reduced; however, at the time of ME recurrence and reinjection, there were site-dependent differences in the changes observed in the CT. These findings suggest that the pathologies of ME at initial occurrence and at the time of recurrence are different.

Abstract
BACKGROUND We conducted this study to report on the indications and types of retinal laser therapy (RLT) performed in Bhutan, knowing which is critical for proper planning and successful delivery of the services. METHODS We reviewed the laser registers maintained in the laser rooms and vitreoretinal (VR) operating theatres (including paediatric cases managed under anaesthesia) over three years at the national and the two regional referral hospitals (RRHs). Intraoperative laser treatments (endolaser) were excluded. Patient demography, indications and types of RLT were recorded and quantified. Comparisons of the expected and observed frequencies used Chi-squared tests. RESULTS A total of 685 patients, including 8 cases of bilateral retinopathy of prematurity (ROP) received RLT. The majority of patients (411 cases, 60.0%, p < 0.0001) were males. The mean age was 54.1 ± 14.1 years, median 56 years. The most common indications for RLT were diabetic retinopathy (DR) and diabetic macular oedema (DMO) (542 cases, 66.0%), followed by retinal vein occlusion (RVO) (91 cases, 13.3%). Pan-retinal photocoagulation was the most common type of RLT performed (337 cases, 49.2%), followed by modified grid laser (207 cases, 30.2%), sectoral laser (41 cases, 6.0%), and prophylactic laser photocoagulation (33 cases, 4.8%). CONCLUSIONS The majority of patients were within working-age. Common indications for RLT were preventable such as DR, DMO and RVO, indicating need to control systemic diseases such as diabetes, hypertension, and dyslipidaemia. Currently, regular RLT is provided only at the national referral hospital in Thimphu, and periodically in the eastern and central RRHs when the retinal specialist visits. There is need to extend the retinal services to the eastern and central RRHs to improve accessibility and patient coverage in these regions challenged with difficult terrain and poor public transport system.

Abstract
BACKGROUND Branch retinal vein occlusion (BRVO) is one of the most commonly occurring retinal vascular abnormalities. The most common cause of visual loss in people with BRVO is macular oedema (MO). Grid or focal laser photocoagulation has been shown to reduce the risk of visual loss. Limitations to this treatment exist, however, and newer modalities may have equal or improved efficacy. Antiangiogenic therapy with anti-vascular endothelial growth factor (anti-VEGF) has recently been used successfully to treat MO resulting from a variety of causes. OBJECTIVES To investigate the efficacy and gather evidence from randomised controlled trials (RCTs) on the potential harms of anti-vascular endothelial growth factor (VEGF) agents for the treatment of macular oedema (MO) secondary to branch retinal vein occlusion (BRVO). SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2019, Issue 6); MEDLINE Ovid; Embase Ovid; the ISRCTN registry; ClinicalTrials.gov; and the WHO ICTRP. The date of the last search was 12 June 2019. SELECTION CRITERIA We included randomised controlled trials (RCTs) investigating BRVO. Eligible trials had to have at least six months' follow-up where anti-VEGF treatment was compared with another treatment, no treatment, or placebo. We excluded trials where combination treatments (anti-VEGF plus other treatments) were used; and trials that investigated the dose and duration of treatment without a comparison group (other treatment/no treatment/sham). DATA COLLECTION AND ANALYSIS Two review authors independently extracted the data using standard methodological procedures expected by Cochrane. The primary outcome was the proportion of participants with an improvement from baseline in best-corrected visual acuity of greater than or equal to 15 letters (3 lines) on the Early Treatment in Diabetic Retinopathy Study (ETDRS) Chart at six months and 12 months of follow-up. The secondary outcomes were the proportion of participants who lost greater than or equal to 15 ETDRS letters (3 lines) and the mean visual acuity (VA) change at six and 12 months, as well as the change in central retinal thickness (CRT) on optical coherence tomography from baseline at six and 12 months. We also collected data on adverse events and quality of life (QoL). MAIN RESULTS We found eight RCTs of 1631 participants that met the inclusion criteria after independent and duplicate review of the search results. These studies took place in Europe, North America, Eastern Mediterranean region and East Asia. Included participants were adults aged 18 or over with VA of 20/40 or worse. Studies varied by duration of disease but permitted previously treated eyes as long as there was sufficient treatment-free interval. All anti-VEGF agents (bevacizumab, ranibizumab and aflibercept) and steroids (triamcinolone and dexamethasone) were included. Overall, we judged the studies to be at moderate or unclear risk of bias. Four of the eight studies did not mask participants or outcome assessors, or both. One trial compared anti-VEGF to sham. At six months, eyes receiving anti-VEGF were significantly more likely to have a gain of 15 or more ETDRS letters (risk ratio (RR) 1.72, 95% confidence interval (CI) 1.19 to 2.49; 283 participants; moderate-certainty evidence). Mean VA was better in the anti-VEGF group at six months compared with control (mean difference (MD) 7.50 letters, 95% CI 5.29 to 9.71; 282 participants; moderate-certainty evidence). Anti-VEGF also proved more effective at reducing CRT at six months (MD -57.50 microns, 95% CI -108.63 to -6.37; 281 participants; lower CRT is better; moderate-certainty evidence). There was only very low-certainty evidence on adverse effects. There were no reports of endophthalmitis. Mean change in QoL (measured using the National Eye Institute Visual Functioning Questionnaire VFQ-25) was better in people treated with anti-VEGF compared with people treated with sham (MD 7.6 higher score, 95% CI 4.3 to 10.9; 281 participants; moderate-certainty evidence). Three RCTs compared anti-VEGF with macular laser (total participants = 473). The proportion of eyes gaining 15 or more letters was greater in the anti-VEGF group at six months (RR 2.09, 95% CI 1.44 to 3.05; 2 studies, 201 participants; moderate-certainty evidence). Mean VA in the anti-VEGF groups was better than the laser groups at six months (MD 9.63 letters, 95% CI 7.23 to 12.03; 3 studies, 473 participants; moderate-certainty evidence). There was a greater reduction in CRT in the anti-VEGF group compared with the laser group at six months (MD -147.47 microns, 95% CI -200.19 to -94.75; 2 studies, 201 participants; moderate-certainty evidence). There was only very low-certainty evidence on adverse events. There were no reports of endophthalmitis. QoL outcomes were not reported. Four studies compared anti-VEGF with intravitreal steroid (875 participants). The proportion of eyes gaining 15 or more ETDRS letters was greater in the anti-VEGF group at six months (RR 1.67, 95% CI 1.33 to 2.10; 2 studies, 330 participants; high-certainty evidence) and 12 months (RR 1.76, 95% CI 1.36 to 2.28; 1 study, 307 participants; high-certainty evidence). Mean VA was better in the anti-VEGF group at six months (MD 8.22 letters, 95% CI 5.69 to 10.76; 2 studies, 330 participants; high-certainty evidence) and 12 months (MD 9.15 letters, 95% CI 6.32 to 11.97; 2 studies, 343 participants; high-certainty evidence). Mean CRT also showed a greater reduction in the anti-VEGF arm at 12 months compared with intravitreal steroid (MD -26.92 microns, 95% CI -65.88 to 12.04; 2 studies, 343 participants; moderate-certainty evidence). People receiving anti-VEGF showed a greater improvement in QoL at 12 months compared to those receiving steroid (MD 3.10, 95% CI 0.22 to 5.98; 1 study, 307 participants; moderate-certainty evidence). Moderate-certainty evidence suggested increased risk of cataract and raised IOP with steroids. There was only very low-certainty evidence on APTC events. No cases of endophthalmitis were observed. AUTHORS' CONCLUSIONS The available RCT evidence suggests that treatment of MO secondary to BRVO with anti-VEGF improves visual and anatomical outcomes at six and 12 months.

Abstract
Purpose The REal life assessmENt of safety And effeCTiveness of Razumab 2 (RE-ENACT 2) study evaluated the long-term effectiveness of biosimilar ranibizumab. We present the subgroup analysis of patients with retinal vein occlusion (RVO). Methods Data of patients who received pro re nata (PRN) biosimilar ranibizumab (November 2015 to December 2018, 17 centers) were analyzed. Endpoints were change from baseline in best corrected visual acuity (BCVA, Snellen’s/logMAR), central subfield thickness (CSFT), intraocular pressure (IOP), and proportions of patients having intraretinal fluid (IRF) and subretinal fluid (SRF) at weeks 4, 8, 12, 16, 20, 24, 30, 36, and 48. Results Of 101 patients, 48.51% were men, and the majority (79.21%) were treatment naïve and had received 3 (range 1–5) injections (53.5%). Significant improvements (P < 0.05) were observed from baseline to all timepoints for BCVA [baseline, 0.89 ± 0.06 (n = 94); week 48, 0.41 ± 0.08 (n = 14)] and CSFT [baseline, 527.58 ± 19.9 (n = 85); week 48, 307.47 ± 16.4 (n = 15)]. Changes in IOP (mmHg) were non-significant [baseline, 15.38 ± 0.4 (n = 94); week 48, 13.94 ± 0.6 (n = 16); P = 0.5575). Proportions of patients having IRF [baseline, 71.3% (n = 84) vs week 48, 0% (n = 15)] and SRF [baseline, 52.5% (n = 83) vs week 48, 0% (n = 15)] were decreased. Similar results for BCVA, CSFT, IOP, IRF, and SRF were observed for BRVO and CRVO subgroups. There were no new safety concerns. Conclusions Biosimilar ranibizumab demonstrated improvements in visual acuity and disease outcomes up to 48 weeks in patients with RVO without any new safety concerns.

Abstract
BACKGROUND The objective of this review and meta-analysis is to investigate the efficacy of conbercept and ranibizumab, combined with or without laser photocoagulation, in patients with macular edema secondary to retinal vein occlusion (RVO-ME). METHODS Several databases have been used to identify relevant publications. After screening, a meta-analysis was conducted to compare conbercept and ranibizumab with the support of RevMan 5.3 (Cochrane Library Software, Oxford, UK). RESULTS In this study, 9 randomized controlled trials and 6 retrospective trials were included with a total of 1180 patients. No significant difference was found in best corrected visual acuity (BCVA) or central macular thickness (CMT) in the baseline parameters [BCVA (weighted mean difference (WMD): -0.01; 95% confidence interval CI: -0.03 to 0.01; P = .17), CMT (WMD: 20.14; 95% CI: -26.70 to 66.97; P = .40). No significant differences were found in the improvements of BCVA and adverse events (AEs) between the 2 groups after injection of loading dosage [the 1st month BCVA (WMD: -0.01; 95% CI: -0.04 to 0.02; P = .54),the 3rd month BCVA (WMD: -0.02; 95% CI: --0.05 to 0.01; P = .23), the 6th month BCVA (WMD: -0.02; 95% CI: -0.05 to 0.01; P = .27), AEs (odds ratio: 0.84; 95% CI: 0.38 to 1.84; P = .66)]. However, there were significant differences between conbercept and ranibizumab treatment in terms of CMT [1st month CMT (WMD: -11.70; 95% CI: -19.71 to -3.68; P < .01), 3rd month CMT (WMD: -10.08; 95% CI: -15.62 to -4.53; P < .01), 6th month CMT (WMD: -15.83; 95% CI: -22.88 to -8.78; P < .01)] and the number of injections (WMD, -0.36; 95% CI: -0.68 to -0.04; P = .03). CONCLUSION The current pooled evidence suggested that both therapies of intravitreal conbercept and intravitreal ranibizumab with or without laser photocoagulation are effective in vision function in RVO-ME patients, and confirmed that conbercept has advantages over ranibizumab in terms of CMT and the number of injections for treating RVO-ME. In addition, conbercept has the statistically same visual gains and safety as ranibizumab in RVO-ME patients. Longer-term follow-up surveys on the safety and effectiveness of these 2 treatment regimens are required.

Effect of image averaging on optical coherence tomography angiography data in eyes with branch retinal vein occlusion. Graefes Arch Clin Exp Ophthalmol 2020; 258:1639-1648. [PMID: 32361802 DOI: 10.1007/s00417-020-04713-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 04/15/2020] [Accepted: 04/21/2020] [Indexed: 12/21/2022] Open
Abstract
PURPOSE To investigate the effect of image averaging on qualitative and quantitative assessments of optical coherence tomography angiography (OCTA) images from eyes of patients with branch retinal vein occlusion (BRVO). METHODS Macular OCTA images of 33 eyes of 33 patients with BRVO were obtained using the HS100 HR-SD-OCT system (Canon, Inc.). For each eye, five OCTA cube scans were obtained with a 3 × 3 mm scan protocol, and the data were averaged and compounded into a single high image quality cube data using built-in software. Pre- and post-averaging images were compared qualitatively and quantitatively in superficial capillary plexus (SCP) and deep capillary plexus (DCP) OCTA image slabs. RESULTS After averaging, all OCTA images showed marked improvement in image quality with less background noise and better vessel continuity. The number of microaneurysms in both the SCP and DCP was larger in single images than in averaged images. A significant increase in the detection rate of capillary telangiectasia in the DCP was noted after image averaging. The number of eyes with disrupted foveal avascular zone (FAZ) decreased significantly after averaging (P = .0253). Five eyes (15.2%) with a disrupted FAZ on the single image showed an intact FAZ after averaging. Vessel length density (VLD) and fractal dimension (FD) significantly decreased and vessel diameter index (VDI) increased after averaging, while significant changes were not observed in vessel density (VD) in both the SCP and DCP. In the SCP, lower VD, VLD, and fractal dimension were significantly correlated with worse visual acuity. CONCLUSIONS OCTA averaging has a significant effect on qualitative and quantitative assessments in eyes with BRVO.

Abstract
Retinal vein occlusion (RVO) is one of the most prevalent causes of visual loss in the Western World. Its pathogenesis is still not completely known. Chronic macular edema and ischemia compromise the functional and anatomical status of the retina. Antivascular endothelial growth factor (anti-VEGF) injections have demonstrated better results than other previous options, including observation or laser therapy. This narrative review aims to analyze the current aspects related to these drugs.

Factors Affecting Compliance to Anti-Vascular Endothelial Growth Factor Treatment of Diabetic Macular Edema in a Cohort of Jordanian Patients. Clin Ophthalmol 2020; 14:921-929. [PMID: 32273676 PMCID: PMC7102883 DOI: 10.2147/opth.s248661] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2020] [Accepted: 03/04/2020] [Indexed: 12/27/2022] Open
Abstract
Purpose To determine compliance rates and characteristics and to investigate factors affecting patients’ adherence to treatment with anti-vascular endothelial growth factors (anti-VEGFs) for diabetic macular edema (DME) in a cohort of Jordanian patients. Methods A retrospective case series wherein the files of DME patients treated with anti-VEGFs were reviewed and analyzed for factors affecting treatment compliance was undertaken. Demographic, clinical and ocular characteristics were recorded. All patients were also interviewed by phone using a structured questionnaire. Univariate and multivariate analyses were performed to determine factors associated with compliance. Results A total of 117 patients (65 males 52 females) were included in this study with a mean age of 62.93 years (±9.75). Approximately, 85% of patients were compliant to their treatment and follow-up plan during the first year of management. Subjective perception of visual improvement after receiving three loading doses was the only independent variable with a unique statistically significant contribution to compliance. All other studied factors in this group of patients were not significantly associated with patient compliance. Conclusion VEGF suppression via the intravitreal route to treat DME is a long-term process that requires caregiver dedication but also proper patient compliance. Addressing real-life barriers in those patients may help guide future strategies to improve the treatment experience, lower the financial burden and contribute to better outcomes. Patients' perceptions of possible treatment outcomes at the short term may influence their long-term commitment to therapy.

Abstract
We aimed to evaluate whether macular laser still has a role in the treatment of macular oedema (MO) caused by branch retinal vein occlusion (BRVO) and provide an overview of recent studies on commonly available treatment options. A literature search was last conducted in PubMed on 26 February 2019, limited to human randomized controlled trials published in English since 2008. Seventeen articles addressing 13 trials were included in this assessment. In trials evaluating intravitreal corticosteroid and macular laser, triamcinolone was non-inferior to laser in regard to visual acuity (VA) and central retinal thickness (CRT) outcomes. Combination treatment of dexamethasone and laser resulted in better VA and lower CRT after 6 months. In trials evaluating vascular endothelial growth factor (VEGF) inhibitors versus macular laser treatment, or sham and rescue laser, better VA and CRT of VEGF inhibition treatment was consistently reported. Results of combination treatment versus VEGF inhibition monotherapy were inconsistent, with four of six studies reporting comparable outcomes and injection burden. Study comparison was affected by considerable differences in study design and inadequate reporting of laser protocol and rescue laser. Studies evaluating angiostatic treatment as monotherapy largely report the use of rescue laser, indicating that some patients would benefit from supplemental laser treatment even in the era of intravitreal therapy. Thus, we suggest further studies on optimal design of combination therapy prioritizing longer follow-up time to sufficiently evaluate the delayed effect of laser.

Abstract
PURPOSE Evaluation of the impact of the injection frequency of ranibizumab on best-corrected visual acuity (BCVA) outcomes in patients with diabetic macular edema (DME). METHODS A meta-analysis of randomized controlled trials (RCTs) and real-world studies was performed to quantify the effect of ranibizumab treatment on BCVA and central foveal thickness (CFT) in DME as well as the relationship between the number of injections and the change in BCVA/CFT. RESULTS All combined sources (29 RCTs and 11 real-life studies) showed a significant increase in BCVA from baseline following anti-vascular endothelial growth factor (VEGF) treatment (8.2, 9.4, and 10.3 ETDRS letters gained after 12, 24, and 36 months of ranibizumab treatment, respectively). The largest changes in BCVA were observed in RCTs and the smallest in real-life studies at 12 months. A significant relationship was found between the number of injections and change in BCVA at 12 months. CONCLUSIONS Inferior vision outcomes were observed in clinical practice compared with RCTs and might be partly attributable to administration of fewer anti-VEGF injections. Physicians should be aware that early and appropriate anti-VEGF treatment regimens are necessary to obtain the results reported in RCTs and help prevent irreversible vision loss in DME patients.

Abstract
The high prevalence of cardiovascular disease particularly in the elderly population is associated with retinal vascular disease. Retinal vein occlusions represent severe disturbances of the hypoxia-sensitive neurosensory retina. Acute and excessive leakage leads to the diagnostic hallmarks of retinal hemorrhage and edema with substantial retinal thickening. Advanced diagnostic tools such as OCT angiography allow to evaluate retinal ischemia and identify the risk for late complications and will soon reach clinical routine besides fluorescein angiography. Accordingly, the duration of non-perfusion is a crucial prognostic factor requiring timely therapeutic intervention. With immediate inhibition of vascular leakage, anti-VEGF substances excel as treatment of choice. Multiple clinical trials with optimal potential for functional benefit or a lesser regenerative spectrum have evaluated aflibercept, ranibizumab, and bevacizumab. As retinal vein occlusion is a chronic disease, long-term monitoring should be individualized to combine maintenance with practicability. While steroids may be considered in patients with systemic cardiovascular risk, surgery remains advisable only for very few patients. Destructive laser treatment is an option if reliable monitoring is not feasible. Ophthalmologists are also advised to perform a basic systemic workup to recognize systemic concomitants. The current edition of the EURETINA guidelines highlights the state-of-the-art recommendations based on the literature and expert opinions in retinal vein occlusion.

Exploring the relationship between collaterals and vessel density in retinal vein occlusions using optical coherence tomography angiography. PLoS One 2019; 14:e0215790.

Abstract
Purpose To characterize the types of collaterals in eyes with retinal vein occlusion (RVO) and further investigate their correlations with vessel densities of the superficial (SCP) and the deep capillary plexus (DCP) using optical coherence tomography angiography (OCTA). Methods This cross-sectional study included 25 eyes of 23 patients with RVO. 3 x 3 mm2 OCTA macular scans were used to quantify the parafoveal vessel density (VD) of the SCP and DCP, and to classify the collaterals into one of four types (true superficial, true deep, superficial diving, and foveal collateral). Generalized estimating equation (GEE) regression analysis was performed to identify significant associations between parafoveal VD and collaterals. We further compared parafoveal VD between subgroups classified by the presence of specific collateral types based on the results of a clustering algorithm. Results 16 of 25 eyes (64%) developed collaterals. Of the 43 collateral vessels analyzed, 12/19 (63%) true superficial collaterals developed in eyes with central RVO, while all 10 superficial diving collaterals (100%) developed in eyes with branch RVO. Located exclusively in the SCP, true superficial collaterals were all arteriovenous (A-V), while diving collaterals were all veno-venular (V-V). We found a significant negative correlation between SCP VD and the total number of collaterals (P < 0.001) for the entire study cohort. Furthermore, BRVO eyes that developed superficial diving collaterals and CRVO eyes that developed true superficial collaterals demonstrated significantly lower SCP VD (P-value = 0.014) and DCP VD (P-value = 0.030), respectively, as compared to the eyes without collaterals in the respective RVO group. Conclusion Our data shows that decreased capillary perfusion in RVO is associated with the development of collaterals, while the RVO type largely dictates the type of collateral that ultimately develops.

Abstract
Purpose
To evaluate the outcomes of different intravitreal injections for the treatment of retinal vein occlusion including central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO). Methods
PubMed, Cochrane, the metaRegister of ControlledTrials, and ClinicalTrials were searched for intravitreal anti-Vascular Endothelial Growth Factor (VEGF) and steroids with relevant keywords and date limitation of 2009-2018. Meta-analysis was performed on studies that met the defined inclusion criteria. Main outcomes were visual acuity (VA) and central macular thickness (CMT). Results Out of 681 studies, 36 articles (including 21 reporting CRVO and 15 dealing with BRVO) were selected for systematic review. All five intravitreal drugs including triamcinolone, dexamethasone, ranibizumab, bevacizumab, and aflibercept showed improvement of CMT and VA as compared to placebo or laser treatment. Six randomized controlled trials were selected for meta-analysis in RVO patients. The pooled mean difference of visual improvement between sham and ranibizumab was 12.7 Early Treatment for Diabetic Retinopathy Study (ETDRS) letters (95%CI: 11.00 to 13.2), and the pooled mean difference in CMT reduction was 221μm (95%CI: 153 to 284); both changes were significantly in favor of ranibizumab. The pooled mean difference of visual improvement between bevacizumab and triamcinolone was 5.3 ETDRS letters in favor of bevacizumab (95%CI: 16 μm to 17.5 μm). Triamcinolone led to 68.1 μm greater CMT reduction than bevacizumab (95%CI: 58 μm to 76 μm). However, none of these differences were statistically significant. Conclusion Treatment with anti-VEGF agents in RVO is superior to observation. No significant difference was seen between the eyes treated with bevacizumab or triamcinolone based on these results.

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 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
PURPOSE To examine the relationship between industry funding and outcome reporting bias in high-quality studies investigating the use of intravitreal anti-vascular endothelial growth factor (VEGF) agents for patients with macular oedema secondary to branch or central retinal vein occlusion (RVO). METHODS This systematic review in PubMed and Ovid MEDLINE examined all randomized clinical trials and meta-analyses published in journals with impact factor of ≥2 that investigated effectiveness of intravitreal anti-VEGF therapy in patients with RVO. The main outcome measure was correspondence between statistical outcome and abstract conclusion wording. RESULTS Forty-five studies met inclusion criteria; 38 (84%) showed correspondence between outcome and abstract conclusion without difference between industry-funded and nonindustry-funded publications (p = 0.39) or between publications in journals with impact factor ≥3 versus <3 (p = 0.96). CONCLUSION In high-quality studies of intravitreal anti-VEGF therapy for RVO, neither industry funding nor journal impact factor affected the rate of outcome reporting bias.

Abstract
Subthreshold micropulse laser treatment has been intensively used for selected retinal diseases in the last decade; however, the exact mechanism of the action of lasers in the subthreshold micropulse mode is not yet fully understood. This kind of treatment is safe and cheap, and contrary to classic laser photocoagulation, it leaves the retinal cells intact. A modern theory of micropulse laser interaction with retinal tissue and a possible explanation of this mechanism are presented in this review. The authors present all the relevant literature on the application of micropulse lasers in different retinal disorders. The efficacy of this treatment is analyzed on the basis of available studies and then placed in the perspective of other therapeutic methods that are used in retinal diseases.

Abstract
BACKGROUND This subgroup analysis of the RE-ENACT study evaluates the effectiveness of Razumab® (the world's first biosimilar of ranibizumab by Intas Pharmaceuticals Ltd.) in Indian patients with retinal vein occlusion (RVO). METHODS The data on patients with RVO who had received ≥3 injections of Razumab® between January and August 2016 were analyzed. Endpoints were: improvement in best corrected visual acuity (BCVA), and a decrease in central macular thickness (CMT), intraretinal fluid (IRF), and subretinal fluid (SRF) from baseline at weeks 4, 8, and 12. RESULTS Of 160 patients, the majority (61.87%) were men. The mean (±SE) BCVA improved from baseline (0.76 ± 0.04) to week 4 (0.73 ± 0.03; p = 0.0656), which attained significance at week 8 (0.55 ± 0.02; p < 0.0001) and week 12 (0.47 ± 0.02; p < 0.0001). The mean (±SE) CMT significantly decreased from baseline (447.60 ± 10.91 μm) to week 4 (431.84 ± 10.92 μm; p = 0.0028), week 8 (339.28 ± 8.12 μm; p < 0.0001), and week 12 (298.23 ± 6.68 μm; p < 0.0001). The proportion of patients with IRF and SRF significantly (p < 0.0001) decreased from baseline to weeks 4, 8, and 12 (IRF: from 70.63 to 45.63, 39.38, and 30.00%, respectively; SRF: from 65.63 to 37.50, 28.13, and 24.38%, respectively). A subgroup analysis of branch RVO and central RVO showed similar results. No new safety concerns were observed. CONCLUSION Razumab® (biosimilar of ranibizumab) effectively improved visual acuity and disease outcomes in patients with RVO in a real-world setting with no new safety concerns.

Head-to-head comparison of ranibizumab PRN versus single-dose dexamethasone for branch retinal vein occlusion (COMRADE-B). Acta Ophthalmol 2018; 96:e10-e18. [PMID: 28251811 DOI: 10.1111/aos.13381] [Citation(s) in RCA: 41] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2016] [Accepted: 12/08/2016] [Indexed: 12/21/2022]
Abstract
PURPOSE To compare the efficacy and safety of ranibizumab 0.5 mg versus dexamethasone 0.7 mg according to their European labels in macular oedema secondary to branch retinal vein occlusion (BRVO) in a 6-month, phase IIIb, randomized trial. METHODS Patients received either monthly ranibizumab for 3 months followed by Pro re nata (PRN) treatment (n = 126) or a sustained-release dexamethasone implant followed by PRN sham injections (n = 118). Main outcomes were mean average change in best-corrected visual acuity (BCVA) from baseline to month 1 through month 6, mean changes in BCVA and foveal centre point thickness (FCPT), and adverse events (AEs). RESULTS There was no difference in BCVA gains between the treatments prior to month 3. Best-corrected visual acuity (BCVA) gain with dexamethasone declined thereafter. From month 3 to month 6, mean BCVA change from baseline was significantly higher with ranibizumab than with dexamethasone [raw means (standard deviation):+16.2 (±11) letters versus +9.3 (±10.1) letters]. At month 6, the difference in BCVA gains from baseline was +17.3 letters in the ranibizumab versus +9.2 letters in the dexamethasone group. Patients in the ranibizumab group received a mean of 2.94 loading injections and 1.74 PRN retreatment injections, while those in the dexamethasone group received a single loading injection. Elevated intraocular pressure (IOP) and AEs were more frequent with dexamethasone than ranibizumab treatment. CONCLUSION Ranibizumab PRN resulted in greater visual acuity (VA) gains in macular oedema following BRVO compared with single-dose dexamethasone over a 6-month study period, observed from month 3, when administered according to their European label. In clinical practice, retreatment with dexamethasone may be required prior to this point.

Abstract
Purpose To compare the short-term effects of three monthly intravitreal bevacizumab (IVB) injections to single dexamethasone (DEX) implantation in treatment-naïve patients with cystoid macular edema (CME) secondary to branch (BRVO) and central retinal vein occlusion (CRVO). Design A retrospective single-center study. Subjects A total of 135 eyes of 135 patients with BRVO (n=83) and CRVO (n=52). Methods Changes in clinical parameters were recorded before treatment and at the first and third month after commencement of IVB (n=121) and DEX (n=14). Main outcome measures Central retinal thickness (CRT), intraocular pressure (IOP), and best-corrected visual acuity (BCVA). Results The baseline parameters were comparable between IVB and DEX groups. After the first month, CRT decreased by 131.3±42.9 μm in IVB and by 266.9±48.3 μm in DEX (mean ± SEM; p=0.047). IOP change was –0.29±0.39 mmHg in IVB and +3.70±2.34 mmHg in DEX (p=0.005). IOP elevation to ≥25 mmHg and ≥5 mmHg from the baseline was observed in two of the DEX- and in none of the IVB-treated eyes (p=0.010). After the third month, no differences regarding CRT and IOP were observed between the treatment modalities. Moreover, BCVA gain was comparable between IVB (0.37±0.05 logarithm of minimum angle of resolution [logMAR] units) and DEX (0.33±0.30 logMAR units) groups. Conclusion DEX was associated with faster resolution of CME, but had greater probability for short-term IOP elevation when compared to IVB. After the third month, treatments were comparably effective. Anatomical outcomes and adverse drug reactions of IVB versus DEX should be considered case specifically in patients having CME secondary to BRVO/CRVO.

Abstract
WHAT IS KNOWN AND OBJECTIVE Therapeutic effects of anti-VEGF agents, corticosteroids and laser therapy have been previously examined for treating macular oedema secondary to branch and central retinal vein occlusion (BRVO and CRVO). However, anti-VEGF efficacy has not been previously compared to corticosteroid or laser therapy efficacy. We performed a meta-analysis to compare these treatments. METHODS Pertinent publications were identified through comprehensive literature searches. Therapeutic effects were estimated using best-corrected visual acuity (BCVA), central retinal thickness (CRT) and intraocular pressure (IOP). The Review Manager (version 5.3.5) was used to perform searches. RESULTS AND DISCUSSION Eleven randomized, controlled trials that included 1045 RVO patients were identified. For eyes with BRVO, anti-VEGF therapy improved BCVA significantly more than corticosteroid/laser therapy at 3 (P=.0002), 6 (P<.00001) and 12 months (P<.00001). For eyes with CRVO, this difference was only significant at 6 months (P=.002). The same was true when efficacy was examined using CRT at 3 and 6 months (BRVO: both P<.00001, CRVO 6 months: P=.02). Long-term efficacy of anti-VEGF agents was limited in eyes with BRVO and CRVO. Improvements in BCVA were similar at 1 and 3 months (P=.74), but BCVA decreased between 3 and 6 months (P=.03). In contrast, BCVA progressively decreased 1 and 6 months following corticosteroid/laser therapy (both P<.00001). Lastly, eyes that had been treated with anti-VEGF agents had significantly lower IOP changes than eyes treated with corticosteroids/laser 3 and 6 months after initiating therapy (both P<.00001). WHAT IS NEW AND CONCLUSION Anti-VEGF agents improve BCVA and reduce CRT more effectively and longer than corticosteroid/laser in eyes with RVO. Anti-VEGF agents also have a lower risk of elevating IOP. Additionally, anti-VEGF agents are more effective for treating BRVO than CRVO.

Abstract
Purpose The purpose of this study was to determine the short-term outcomes for patients who received intravitreal aflibercept (IVA) with or without intravitreal ranibizumab (IVR) for macular edema (ME) due to branch retinal vein occlusion (BRVO). Patients and methods Patients received IVA for ME due to BRVO. Patients who initially received IVA were defined as the treatment-naïve group and those who were switched from IVR to IVA after ME recurrence were defined as the switching group. Patient outcomes were examined at 1 week and 1 month postinjection. Results Both groups comprised 27 eyes from 27 patients. There was a significant decrease in central macular thickness (CMT) at 1 week and 1 month postinjection in both groups. There was also a significant improvement in best-corrected visual acuity (BCVA) at 1 week and 1 month postinjection in the treatment-naïve group and 1 month in the switching group. Younger age was associated with a good BCVA at 1 month postinjection in the switching group, and the absence of epiretinal membrane was associated with a reduction in CMT at 1 month postinjection in the switching group. Conclusion IVA is temporarily effective for treating ME due to BRVO regardless of a history of IVR use.

Abstract
Purpose. To compare the controllability of navigated macular laser photocoagulation (MLP) in dry versus edematous retina and validate that pretreatment diagnostic images can be used as basis for navigated MLP after the macular edema (ME) has been resolved. Materials and Methods. Group 1 was divided into subgroup 1 (dry retina MLP) and subgroup 2 (MLP in ME) for comparisons of laser-burn diameters. In group 2, the areas and locations of ME before an intravitreal injection of anti-VEGF (IVAV) were compared with those of recurrent ME. Results. The average actual diameter as percentage of planned diameter of laser burn in subgroup 1 (11 DME eyes, 6 BRVO eyes) versus subgroup 2 (5 DME eyes, 8 BRVO eyes) was 115.1 ± 9.1% versus 167.2 ± 13.8% (based on retro-mode scanning laser ophthalmoscopy), and 118.1 ± 14.8% versus 176.1 ± 11.6% (based on OCT) (p < 0.001). In group 2 (6 DME eyes, 6 BRVO eyes), difference in mean ME area before IVAV and that in recurrent edema was insignificant (p > 0.05). Conclusion. The controllability of navigated MLP in dry retina is improved compared to edematous retina. This study validates that pretreatment diagnostic images can be used as basis for navigated MLP after the edema has been resolved.

Abstract
Purpose To evaluate the 3-month natural course of recurrent macular edema secondary to branch retinal vein occlusion (BRVO) treated with intravitreal bevacizumab. Methods This retrospective, observational study included 36 eyes with macular edema secondary to BRVO. All patients were initially treated with intravitreal bevacizumab for macular edema. Recurrence of macular edema was either not treated (untreated group) or treated with a single intravitreal bevacizumab injection (treated group). Central foveal thickness (CFT) and best-corrected visual acuity (BCVA) were compared at the time of recurrence and 3 months later. Results At the time of recurrence, the mean CFT and logarithm of the minimum angle of resolution BCVA were 484.9 ± 124.1 µm and 0.58 ± 0.26 in the untreated group (n = 19) and 456.3 ± 126.8 µm and 0.51 ± 0.21 in the treated group (n = 17), respectively. Three months later, the mean CFT and BCVA had changed to 493.7 ± 123.9 µm and 0.62 ± 0.29 in the untreated group and 294.7 ± 104.4 µm and 0.40 ± 0.24 in the treated group, respectively. The differences in CFT and BCVA between the two time points were not significant in the untreated group (p = 0.106 and p = 0.687, respectively), whereas statistically significant differences were noted in the treated group (p = 0.002 and p < 0.001, respectively). Conclusions Unlike the first episode of macular edema following BRVO, recurrent macular edema following intravitreal bevacizumab therapy did not spontaneously resolve, suggesting the potential benefit of prompt treatment.

Abstract
PURPOSE This study reports the findings in a large series of patients with acute bacterial endophthalmitis after intravitreal injection of bevacizumab (IVB) in two eye hospitals. METHODS Medical records were reviewed for patients who presented with acute fulminant endophthalmitis in one or two eyes following intravitreal injection of bevacizumab from two separate batches in two eye hospitals. RESULTS Twenty-eight eyes of 21 patients presented with acute endophthalmitis 12-48 hours after IVB injection. Cultures from the eyes and the vials were positive for E. coli and Citrobacter, each in one of the hospitals. All patients were initially treated with topical, intravitreal, and systemic antibiotics. Twenty-four eyes underwent pars plana vitrectomy. Best corrected visual acuity (BCVA) was 1.27 ± 0.89 logMAR before IVB injecti,on which decreased to 2.80 ± 0.45 LogMAR after presentation of endophthalmitis and 2.12 ± 0.97 logMAR three months after IVB injection. Final visual acuity was found to be no light perception in four eyes. CONCLUSIONS This large outbreak of E.coli and Citrobacter endophthalmitis occurred after intravitreal injection of counterfeit bevacizumab. Visual outcomes were very poor.

Abstract
PURPOSE The purpose of this study was to determine the clinical efficacy of low-frequency intravitreal ranibizumab to treat macular edema due to retinal vein occlusion (RVO). PATIENTS AND METHODS This was a retrospective examination of cases that received intravitreal ranibizumab for untreated RVO over a period of 12 months. Instead of the conventional three monthly injections, injections were given once during the introductory period. If the recurrence of macular edema was diagnosed during the monthly visit, additional injections were given as needed. There were 21 eyes of 21 patients with branch RVO (BRVO) and ten eyes of ten patients with central RVO (CRVO). The parameters examined included the number of injections over the 12-month period, improvements in best-corrected visual acuity (BCVA), and the central macular thickness (CMT). For BRVO, preinjection parameters that had an effect on the prognosis of BCVA after the 12-month period were also examined. RESULTS The total mean number of injections over the 12-month period was 3.4 for CRVO and 2.1 for BRVO. For CRVO, the BCVA in log minimum angular resolution changed from a preinjection value of 0.80 to 0.55 at 12 months. For BRVO, the change was from 0.51 to 0.30. For all diseases, BCVA improved after 12 months compared with the preinjection values (P<0.05). There was improvement in the CMT, and the CRVO changed from 765.0 μm at preinjection to 253.5 μm 12 months later. BRVO changed from 524.1 to 250.1 μm, and pre-injection BCVA was associated with a prognosis of visual acuity after 12 months of the initial injection (P=0.0485). CONCLUSION Even with a low number of injections during the introductory period, there were still improvements in both visual acuity and CMT in RVO patients after 12 months, indicating that it was an effective treatment.

Abstract
The development of lasers for biological use was an important medical advance in the 20th century with numerous evidence-based therapeutic applications to retinal disease, including capillary leakage at the macula. Although the role of photocoagulative laser in the treatment of macular oedema has diminished, there is evidence for a modified role in clinical management, particularly for extrafoveal leakage. Additionally, it may reduce the frequency of required intravitreal injections and assist in visual stabilization when used as an adjunct. The tissue destructive effect of photocoagulative lasers has motivated the development of safer macular lasers and the search for novel therapeutic applications, including treatment of drusen and regeneration of dysfunctional retinal pigment epithelium.

Abstract
Branch retinal vein occlusion (BRVO) is the second most common retinal vascular disorder. The management of macular edema has changed considerably over time. The laser is considered the gold standard treatment for over two decades. However, visual recovery with laser is usually slow and incomplete. The advent of intravitreal agents, specifically anti-vascular endothelial growth factors (VEGF) have heralded a new era which promises rapid recovery of vision and quality of vision. Randomized clinical trials have reported optimal results with anti-VEGF agents (ranibizumab, bevacizumab, and aflibercept) compared to laser therapy or steroids. However, nearly 50% of the patients require repeat intravitreal anti-VEGF therapy up to 4 years after initiating therapy to sustain the visual gains. The adverse events (systemic and ocular) of these agents are minimal. Monotherapy with anti-VEGF agents have been found to provide better results than any combination with laser. This review article summarizes evidence from randomized controlled trials evaluating treatment options for the treatment of macular edema secondary to BRVO with a special focus on anti-VEGF therapy.

Abstract
For years, the standard of care for branch-retinal-vein-occlusion-associated macular edema was initial observation followed by grid-pattern laser photocoagulation for persistent edema. Newer pharmacologic options have revolutionized the management of branch-retinal-vein-occlusion-associated macular edema, and the visual outcomes of these eyes are better than ever. However, a variety of available treatment options including intravitreal corticosteroids and intravitreal anti-vascular endothelial growth factor agents have established novel challenges with regard to appropriate drug selection. This review summarizes the available clinical studies with special emphasis on the comparison of intravitreal aflibercept with ranibizumab, bevacizumab, and steroid agents.

Abstract
There are 3 approved pharmaceutical agents for treating macular edema secondary to retinal vein occlusion (RVO): dexamethasone (a corticosteroid) implant and ranibizumab and aflibercept (both antivascular endothelial growth factor agents). All show a superior ability to improve vision and reduce macular thickness in comparison with sham injections or macular grid laser treatment. Prompt treatment with these agents may lead to a better outcome. A review of randomized trials of injected aflibercept or ranibizumab reveals protocol variations. They include "as needed" injections until functional and anatomical changes are achieved, preceded by either 1 injection or 3 to 6 monthly injections as loading doses. Ocular and systemic adverse effects of vascular endothelial growth factor antagonists for macular edema secondary to RVO are rarely severe. The antiedematous response to a single intravitreal dexamethasone implant is maximal 1 to 3 months after the injection. Intraocular pressure elevation and cataract aggravation should be monitored after the use of intravitreal dexamethasone implants. Intravitreal dexamethasone implants and ranibizumab injections reduce not only macular edema, but also the risk of retinal ischemia and neovascularization in patients with RVO.

Effect of leaking capillaries and microaneurysms in the perifoveal capillary network on resolution of macular edema by anti-vascular endothelial growth factor treatment. Jpn J Ophthalmol 2016; 60:86-94. [PMID: 26801502 DOI: 10.1007/s10384-016-0425-5] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2015] [Accepted: 12/16/2015] [Indexed: 01/08/2023]
Abstract
PURPOSE To investigate the effect of leaking capillaries and microaneurysms (MAs) in the perifoveal capillary network (PCN) on the treatment of fovea-involving macular edema (ME) secondary to branch retinal vein occlusion (BRVO) by intravitreal ranibizumab (IVR) injections combined with focal, grid, and scatter laser photocoagulation. METHODS Retrospective comparative case series. The MA (+) group consisted of 12 patients with leaking MAs in the PCN and the MA (-) group contained 11 patients without. At 6 months following the initial IVR injection, best corrected visual acuity (BCVA) was evaluated as the primary outcome. Secondary outcomes included central macular thickness (CMT) and the number of IVR injections performed in a pro re nata (PRN) regimen when CMT was ≥300 µm and vision deteriorated by 0.1 logMAR or greater. RESULTS Mean BCVA improved by 0.30 ± 0.25 logMAR in the MA (-) group and 0.28 ± 0.20 logMAR in the MA (+) group (both P < 0.0001). Mean CMT was reduced by 237.6 ± 221.4 µm (P < 0.0001) in the MA (-) and 158.2 ± 152.1 µm (P < 0.01) in the MA (+) group. The degrees of improvement in BCVA (P = 0.74) and CMT (P = 0.33) did not vary significantly between the groups. The mean number of additional IVR injections was significantly less in the MA (-) group than in the MA (+) group (2.2 ± 1.0 vs 3.0 ± 0.8; P = 0.04). CONCLUSIONS Although leaking MAs and capillaries in the PCN did not adversely affect improvements in BCVA and CMT, these manifestations led to an increased number of IVR injections needed to sustain resolution of ME involving the fovea.

Abstract
PURPOSE To evaluate long-term results and predictors of efficacy in patients with macular edema due to retinal vein occlusion (RVO) treated with intravitreal ranibizumab in a clinical practice setting. METHODS The clinical records of patients with a minimum follow-up of 3 years were retrospectively analyzed. Sixteen eyes with branch RVO (BRVO) and 16 with central RVO (CRVO) were included. All patients performed cross-sectional evaluation with best-corrected visual acuity (BCVA), spectral domain optical coherence tomography and fluorescein angiography. The foveal avascular zone (FAZ) was assessed and microstructural morphology of the retina was characterized. RESULTS Follow- up was 42.9 ± 9.0 and 44.8 ± 8.0 months in the CRVO and BRVO groups, respectively. Patients with CRVO received on average 6.9 injections, with a final VA gain of 8.3 ± 15.0 letters (p = 0.05). BRVO eyes had on average 5.9 injections, with a final VA gain of 1.6 ± 21.0 letters (p > 0.05). The FAZ area remained stable in both groups (p > 0.05). Baseline BCVA and disruption of the retinal pigment epithelium (RPE) were predictors of final BCVA (p = 0.001 and 0.011, respectively). CONCLUSION Although functional outcomes were inferior to those reported in clinical trials, ranibizumab was satisfactory in the long-term treatment of macular edema secondary to RVO and was not associated with increased macular ischemia. Final BCVA depends on baseline BCVA and RPE integrity.

Abstract
Macular edema (ME) is the most common complication of both ischemic and nonischemic retinal vein occlusion (RVO). If the main trunk of the central retinal vein is involved, ME occurs in 100% of cases. According to the Central Vein Occlusion Study, in 65% of RVO and ME patients with baseline visual acuity (VA) of at least 0.5 (Golovin-Sivtsev chart) or higher, ME may resolve itself without treatment with subsequent VA improvement. Therefore, we recommend a 3-month treatment-free follow-up of nonischemic central RVO (CRVO) and ME patients with VA of 0.5 or higher. If no improvement is noted within this period, treatment is initiated. Immediate treatment is required in patients with cystic ME revealed by optical coherence tomography (OCT) and VA below 0.5. Ischemic maculopathy is extremely unpromising. Modified grid laser photocoagulation should not be used as monotherapy for macular edema. Repeated corticosteroid (Ozurdex) and/or anti-VEGF (ranibizumab, aflibercept) intravitreal injections are considered the first choice treatment for ME in CRVO patients. Efficiency assessments should include monthly OCT. For persistent ME, intravitreal therapy can be supplemented by laser retinal photocoagulation (panretinal or modified grid). Anti-VEGF treatment schemes should be adjusted in BRVO patients as most of their edemas are self-limiting. Of laser photocoagulation techniques, only modified grid is used.

Abstract
Purpose To evaluate the differences in the development of collateral vessels in patients with macular edema due to branch retinal vein occlusion (BRVO) after treatment with either grid laser or ranibizumab (RNB). Methods Comparative study including patients with macular edema due to acute BRVO and best-corrected visual acuity (BCVA) between 20/40 and 20/200. The sample was divided into two groups according to the treatment applied: laser group, including eyes treated with Argon laser when retinal hemorrhages were sufficiently absorbed to perform the treatment, and RNB group, including patients treated initially with one monthly intravitreal injection for a period of 3 months of RNB and more injections according to need thereafter. Before treatment patients in both groups, received a complete ophthalmic examination, including BCVA, fundus examination, optical coherence tomography, fundus color photography, and fundus fluorescein angiography (FA). This same protocol of examination was repeated in every visit after treatment, except FA that was only repeated every 3 months. The detection of the collateral vessels was done by two experienced examiners based on the analysis of the early phase of the FA. If there was a discrepancy in their judgment, the criterion of a third examiner evaluating the FA was considered. Results Mean baseline BCVA was 0.86±0.26 and 0.82±0.25 (logMAR [logarithm of the minimum angle of resolution]) in the RNB and laser groups, respectively (P=0.83). At the end of the follow-up, mean BCVA was 0.38±0.18 and 0.64±0.33 (logMAR) in the RNB and laser groups, respectively. The difference in the final BCVA between both groups was statistically significant (P=0.002). Collaterals developed in both groups; 66.67% of patients (14 out of 21 patients) developed collaterals at a mean time of 6.14±2.60 months after diagnosis in the RNB group, and 68.18% (16 out of 22 patients) developed collaterals in the laser group at a mean time of 6.2±1.97 months after diagnosis. No statistically significant differences between groups were found in the number of cases developing collateral vessels (P=1.00) as well as in the time required for such development (P=0.947). Conclusion The use of RNB for the treatment of macular edema due to BRVO does not seem to alter the development of collateral vessels. Future studies with larger samples are required to confirm these outcomes.

Abstract
OBJECTIVE To compare the efficacy and safety of approved treatments for macular oedema secondary to branch retinal vein occlusion (BRVO). DESIGN Randomised controlled trials (RCTs) evaluating the efficacy and safety of approved treatments for macular oedema secondary to BRVO were identified from an updated systematic review. SETTING A Bayesian network meta-analysis of RCTs of treatments for macular oedema secondary to BRVO. INTERVENTIONS Ranibizumab 0.5 mg pro re nata, aflibercept 2 mg monthly (2q4), dexamethasone 0.7 mg implant, laser photocoagulation, ranibizumab+laser, or sham intervention. Bevacizumab and triamcinolone were excluded. OUTCOME MEASURES Efficacy outcomes were mean change in best corrected visual acuity (Early Treatment Diabetic Retinopathy Study scale) and the percentage of patients gaining ≥ 15 letters. Safety outcome was the percentage of patients with increased intraocular pressure (IOP)/ocular hypertension (OH). RESULTS 8 RCTs were identified for inclusion with 1743 adult patients. The probability of being the most efficacious treatment at month 6 or 12 based on letters gained was 54% for ranibizumab monotherapy, 30% for aflibercept, 16% for ranibizumab plus laser (adjunctive or prompt), and 0% for dexamethasone implant, laser or sham. The probability of being the most efficacious treatment for patients gaining ≥ 15 letters was 39% for aflibercept, 35% for ranibizumab monotherapy, 24% for ranibizumab plus laser, 2% for dexamethasone implant, and less than 1% for laser or sham. There was no statistical difference between ranibizumab monotherapy and aflibercept for letters gained (+1.4 letters for ranibizumab vs aflibercept with 95% credible interval (CrI) of -5.2 to +8.5 letters) or the OR for gaining ≥ 15 letters: 1.06 (95% CrI 0.16 to 8.94)). Dexamethasone implant was associated with significantly higher IOP/OH than antivascular endothelial growth factor agents (OR 13.1 (95% CrI 1.7 to 116.9)). CONCLUSIONS There was no statistically significant difference between ranibizumab and aflibercept.
