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

Abstract
BACKGROUND Although intravitreal anti-vascular endothelial growth factor therapy is currently considered the first-line treatment for chorioretinal vascular diseases in Japan, information regarding its treatment pattern is scarce. This study investigated the patterns of anti-vascular endothelial growth factor treatment for chorioretinal vascular diseases. METHODS A health insurance claims database from acute care hospitals was used to estimate treatment intervals and continuation and drop-out rates regarding the anti-vascular endothelial growth factor. Patients aged ≥50 years diagnosed with neovascular age-related macular degeneration or aged ≥18 years diagnosed with diabetic macular edema or retinal vein occlusion were analyzed. RESULTS Data were included for 76,535, 49,704, and 37,681 patients with neovascular age-related macular degeneration, diabetic macular edema, and retinal vein occlusion, respectively; exactly 8,111, 2,283, and 6,896 received the treatment, respectively. The mean and median interval ranges during the maintenance phase by treatment initiation year were 94-100 and 73-80, 111-120 and 98-102, and 97-103 and 87-93 days for neovascular age-related macular degeneration, diabetic macular edema, and retinal vein occlusion, respectively, without any trend over time. A tendency to increase the treatment continuation rate was indicated in later years by Kaplan-Meier curves. The drop-out rate in the treatment initiation year (2016) was 32% from 63% (2009), 53% from 69% (2014), and 36% from 47% (2013) for neovascular age-related macular degeneration, diabetic macular edema, and retinal vein occlusion, respectively. CONCLUSIONS For all these diseases, the treatment intervals did not change remarkably, and a tendency toward improved treatment continuation was suggested.

Abstract
Introduction This single-center retrospective cohort study investigated the incidence rate and risk factors for the discontinuation of anti-vascular endothelial growth factor (VEGF) injections and retreatment in typical neovascular age-related macular degeneration (tnAMD) and polypoidal choroidal vasculopathy (PCV) in the real-world setting. Methods A total of 488 eyes with either tnAMD (n = 334) or PCV (n = 154) followed up for ≥3 years were analyzed. The discontinuation of treatment was defined as the cessation of anti-VEGF injections for 1 year or longer. Eyes with discontinuing treatment were subdivided into group A: eyes with stable responses (complete or incomplete resolution) and group B: those with no expectation of visual gain or poor response. The proportion and median time of discontinuation of treatment or retreatment were analyzed. The visual prognosis and the associated risk factors for the discontinuation of treatment or retreatment were also investigated. Results The mean follow-up period was 8.1 ± 3.4 years. Of 488 eyes, discontinuation of the treatment occurred in 322 eyes (66.0%), and the median time to discontinuation was 1.5 years after the initial injection. Of 297 eyes with discontinuation of treatment excluding 25 eyes with vitrectomy or photodynamic therapy after the discontinuation of the injection, 277 eyes belonged to group A and the remaining 20 eyes belonged to group B. Of the 277 eyes discontinuing treatment with a stable response, 185 eyes (66.8%) were given retreatment. The median time to retreatment was 3.3 years after the discontinuation of the injections. PCV and the lower annual number of injections were the significant factors associated with discontinuation. Younger age, male gender, and PCV were the significant factors for the retreatment. Conclusion Our long-term real-world study showed that two-thirds of eyes with neovascular age-related macular degeneration (nAMD) had the discontinuation of the anti-VEGF injections and two-thirds of eyes discontinuing treatment with stable responses experienced retreatment. Long-term follow-up and regular monitoring are needed to detect the recurrence.

Abstract
PURPOSE To report the rate of delayed follow-up visits (DFU), to identify risk factors of DFU and to assess the impact of DFU on outcomes in neovascular age-related macular degeneration (nAMD). PATIENTS AND METHODS This retrospective study included all nAMD patients (n=1291) treated with anti-vascular endothelial growth factor (VEGF) injections between January 2013 and December 2020 in two centers in Quebec, Canada. A DFU was defined as a delay of ≥4 weeks than scheduled. Visual outcomes, especially ≥15 letters loss, were reported. RESULTS A total of 351 patients (27.2%) experienced ≥1 DFU. Odds were greater among older patients (P=0.005), patients treated at the hospital rather than the clinic (P<0.001), and patients with worse initial visual acuity (VA) (P=0.024). A DFU was associated with a mean VA loss of 4.2±13.4 letters (P<0.001), and an increased incidence of intraretinal (IRF) and subretinal fluid (SRF) (P=0.001, P=0.005) at six months despite resumption of injections. Central foveal thickness (CFT) increased after DFU but returned to pre-DFU visit at 6 months. CONCLUSIONS The DFU rate in nAMD patients treated under a universal healthcare system was around 27%. DFU caused significant decreases in VA and increases in IRF and SRF on OCT that did not recover following injections resumption despite normalization of CFT.

Abstract
The use of anti-vascular endothelial growth factor (VEGF) agents has profoundly changed the prognosis of neovascular age-related macular degeneration (nAMD). As clinical experiences have accumulated, it has become mandatory to summarize data to give information that can be useful in everyday practice. We conducted a systematic review to identify randomized controlled trials (RCTs) and observational studies that reported 12-month changes in best-corrected visual acuity (BCVA) in patients with nAMD on anti-VEGF monotherapy. Data were analyzed in a random-effects meta-analysis with BCVA change as the primary outcome. Meta-regression was conducted to evaluate the impact of multiple covariates. Four hundred and twelve heterogeneous study populations (109,666 eyes) were included. Anti-VEGFs induced an overall improvement of +5.37 ETDRS letters at 12 months. Meta-regression showed that mean BCVA change was statistically greater for RCTs (p = 0.0032) in comparison with observational studies. Populations following a proactive regimen had better outcomes than those following a reactive treatment regimen. Mean BCVA change was greater in younger populations, with lower baseline BCVA and treated with a higher number of injections (p < 0.001). Our results confirm that anti-VEGFs may produce a significant functional improvement at 12 months in patients with nAMD.

Abstract
Visual acuity is a key outcome measure in the treatment of neovascular age-related macular degeneration (nAMD) using anti-vascular endothelial growth factor agents. Large variations in visual responses between individuals within clinical trials and real-world studies may relate to underlying differences in patient and treatment factors. Most notably, a better baseline visual acuity, younger age and smaller choroidal neovascularization lesion size have been strongly associated with achieving better visual outcomes. In addition, there is emerging evidence for other roles including genetic factors and anatomical variables such as fluid status. Apart from patient-related factors, treatments that favor a higher number of injections tend to provide better visual outcomes. Overall, the identification of predictive factors does not currently play an essential role in the clinical management of patients with nAMD. However, they have allowed for the understanding that early detection, timely management and close monitoring of the disease are required to achieve optimal visual outcomes. Further investigation into predictive factors alongside the development of novel therapeutic agents may one day provide a means to accurately predict patient outcomes. Treatment regimens that offer flexible dosing patterns such as the treat-and-extend strategy currently provide a degree of personalization during treatment.

Abstract
INTRODUCTION To describe the one-year functional outcomes of treatment-naïve neovascular age-related macular degeneration (nAMD) treated with anti-VEGF agents at the Dijon University Hospital Ophthalmology Department. METHODS Real-life interventional study including all treatment-naïve nAMD patients from January 2016 to December 2018 in the Ophthalmology Department of Dijon University Hospital. Data were retrospectively collected from the Fight Retinal Blindness! (FRB!) registry. At baseline, medical history, visual acuity (VA), type of lesion and activity on angiography and optical coherence tomography (OCT), and treatment were recorded. On follow-up, VA, lesion activity and treatment were recorded. RESULTS Three-hundred twenty eyes of 259 patients were included, of which 65.6% were female and with a mean age of 80.1±11.1 years. Mean VA (standard deviation, SD) at baseline was 53.2 ETDRS letters (25.3). All patients received anti-VEGF injections, of which 164 eyes (51.2%), 152 eyes (47.5%) and 4 eyes (1.2%) were treated with aflibercept, ranibizumab and bevacizumab, respectively. A total of 198 eyes of 169 patients completed the 12-month follow-up, with a median (first quartile, third quartile) of 12 visits (10, 13). At one year (n=198), the overall mean VA gain [95% CI] was +3.3 ETDRS letters [0.7, 5.9] and 173 (87.4%) of the treated eyes did not lose 15 or more letters. We found no statistically significant difference in mean VA gain between aflibercept and ranibizumab. CONCLUSION This real-world study confirmed the efficacy of anti-VEGF agents in nAMD and the feasibility of analyzing data in an international registry.

Abstract
Purpose Subretinal fibroneovascularization is one of the most common causes of vision loss in neovascular AMD (nAMD). Anti-VEGF therapy effectively inhibits vascular leak and neovascularization but has little effect on fibrosis. This study aimed to identify a combination therapy to concurrently inhibit subretinal neovascularization and prevent fibrosis. Methods We generated transgenic mice in which induced disruption of Müller cells leads to subretinal neovascularization, which is reliably accompanied by subretinal fibrosis. We conducted Western blots and immunohistochemistry to study changes in transforming growth factor-β (TGFβ) signaling including endoglin, a coreceptor essential for TGFβ signaling, and then tested the effects of monthly intravitreal injection of anti-VEGF-A and anti-endoglin, either alone or in combination, on the development of subretinal fibroneovascularization in our transgenic mice. Results Müller cell disruption increased expression of TGFβ1, TGFβ type 1 receptor, and phosphorylated-Smad3. Endoglin was strongly expressed in subretinal fibroneovascular tissue. Fluorescein angiography and measurements of retinal vascular permeability indicated that intravitreal anti-VEGF-A in combination with anti-endoglin treatment more efficiently inhibited vascular leak compared with either monotherapy. Immunostaining of retinal wholemounts with antibodies against glial fibrillary acidic protein and ionized calcium binding adaptor molecule 1 indicated that the combination therapy also effectively prevented subretinal fibrosis and inhibited microglial activation. Luminex cytokine assays indicated that intravitreal anti-VEGF-A and anti-endoglin treatment, either alone or in combination, reduced the production of IL33 and macrophage inflammatory protein-3α. Conclusions Our findings offer a potentially novel combination approach to concurrently managing subretinal neovascularization and fibrosis in nAMD.

Abstract
PURPOSE To assess mean change in visual acuity (VA) overall and stratified by baseline VA after 1 and 2 years' treatment with aflibercept in a real-life setting. METHODS This was an observational cohort study using nationwide data from the Swedish Macula Register. Treatment-naïve patient eyes with wet age-related macular degeneration and prescribed aflibercept from January 2013 to December 2014 were followed for 1 year (2478 eyes) or 2 years (831 eyes) to assess VA. Eyes were grouped by baseline VA. RESULTS Mean number of injections in patients treated according to label (72%) versus patients treated not according to label was 8.0 ± 1.5 versus 4.4 ± 0.8 (p < 0.0001) at 1 year, and 12.5 ± 3.2 versus 7.3 ± 1.9 (p < 0.0001) at 2 years. Among all eyes, mean VA increased from 61.3 ± 13.4 Early Treatment Diabetic Retinopathy Study letters at baseline to 64.5 ± 15.6 at 1 year and 65.1 ± 15.1 letters at 2 years. At 2 years, eyes with good baseline vision (≥70 letters) lost a mean of 2.4 ± 11.3 to 72.3 letters, eyes with intermediate baseline VA (36-69 letters) gained 5.7 ± 14.1 to 62.7 letters, and eyes with poor baseline VA (≤35 letters) gained 13.2 ± 18.3 to 41.0 letters. Also at 2 years, 75% of treated eyes were stable or had improved VA. Among eyes with intermediate baseline VA, near vision was significantly better among those treated according to label versus not according to label at 3 (p = 0.019), 6 (p = 0.0002) and 12 months (p ≤ 0.0001). CONCLUSION While gain in vision was especially pronounced in eyes with poor baseline VA, good baseline VA was important for best prognosis.

Abstract
PURPOSE To present Swedish Macula Register (SMR) data regarding treatment of neovascular age-related macular degeneration (AMD) in clinical practice since 2008. METHODS A retrospective register-based study was conducted. Evaluation of baseline demographics, visual outcome and number of injections during this period is presented. RESULTS Mean age at diagnosis was 79 ± (SD) 8 years; 65% were female. The proportion of patients with <2 months' duration of symptoms increased from 26% in 2008 to 41% in 2014 (p = 0.001). Mean visual acuity (VA) at baseline increased from 54.3 ± 15.0 early treatment diabetic retinopathy study (ETDRS) letters in 2008 to 57.8 ± 15.6 letters in 2014 (CI95 2.6; 4.3; p < 0.001). Mean VA after 1 year of treatment increased from 57.8 ± 17.7 ETDRS letters for patients who started the treatment in 2008 to 62.8 ± 16.4 ETDRS letters in patients starting treatment in 2014 (CI95 2.67; 4.64; p < 0.001). During all study years, the proportion of patients with an improvement in VA of between 5 and 15 letters was around 30%, while 14% had VA improvement of more than 15 letters. The mean number of injections during the first treatment year increased from 4.3 ± 1.9 in 2008 to 5.9 ± 2.9 in 2014 (CI95 1.40; 1.67; p < 0.001). Seven-year follow-up of 322 eyes showed a mean change of -1 letters from baseline, with a mean of 21 injections for the entire period. CONCLUSION The duration of symptoms before treatment decreased, while VA at baseline and after 1 year of treatment increased over the years and so did the number of injections. Long-term follow-up demonstrated stable VA.
