Abstract Background: To evaluate the influence of anti-vascular endothelial growth factor (VEGF) in the appearance or progression of epiretinal membranes (ERMs) in age-related macular degeneration (ARMD) and investigate determining factors.Methods: Seventy-six eyes that were treated for more than 36 months from the first anti-VEGF injection were assessed. Binary logistic regression analysis was performed between smoking, lens status, subretinal hemorrhage, posterior vitreous detachment (PVD) status, peripheral degeneration, contralateral eye, and the number of injections as independent variables and appearance or progression of ERMs during 36 months as dependent variables.Results: The presence of vitreous macular adhesion (VMA) or development of PVD during the observation period was significantly associated (Odds ratio [OR]: 5.76; 95% confidence limit [CL], 1.72-19.3; p＝0.005) with the appearance or progression of ERMs. Moreover, peripheral retinal degeneration was significantly associated (OR: 3.85; 95% CL, 1.15-13.0; p＝0.029). Injection number of anti-VEGF was not significantly associated (OR: 1.02; 95% CL, 0.90-1.16; p＝0.73). Number of anti-VEGF injections in ARMD had little relationship with developing secondary ERMs. VMA or developing PVD and peripheral degenerations had an association with developing ERMs. Conclusion: This study suggests possibilities that anti-VEGF injections alone are unable to cause the development of ERMs, that the vitreoretinal interface has a prior impact on the developing ERMs in ARMD similar to that of idiopathic ERMs, and that peripheral degenerations co-exist with or are evoked by vitreoretinal adhesion in the pathogenesis of ARMD, both being related to ERMs development.

Abstract Background The purpose of this study is to evaluate the influence of anti-vascular endothelial growth factor (VEGF) in the appearance or progression of epiretinal membranes (ERMs) in age-related macular degeneration (ARMD) and investigate confounding factors causing ERMs. Methods Seventy-six eyes that were treated for more than 36 months from the first anti-VEGF injection were assessed. Binary logistic regression analysis was performed between smoking, lens status, subretinal hemorrhage, posterior vitreous detachment (PVD) status, peripheral retinal degeneration, type of AMD, conditions of contralateral eye, and the number of injections as independent variables and appearance or progression of ERMs during 36 months as dependent variables. Results The presence of vitreomacular adhesion (VMA) or development of PVD during the observation period was significantly associated (Odds ratio [OR]: 5.77; 95% confidence interval [CI], 1.72–19.4; p = 0.005) with the appearance or progression of ERMs. Moreover, peripheral retinal degeneration was significantly associated (OR: 3.87; 95% CI, 1.15–13.0; p = 0.029). Injection number of anti-VEGF was not significantly associated (OR: 1.02; 95% CI, 0.90–1.16; p = 0.72).

Pegaptanib sodium is a polyethylene-glycolated, 28-nucleotide RNA aptamer that binds selectively to vascular endothelial growth factor (VEGF)165 but not smaller isoforms. Preclinical studies identified VEGF165 as an especially potent promoter of ocular neovascularization and inflammation. Following the pivotal clinical trials demonstrating the efficacy of intravitreal pegaptanib in treating all angiographic subtypes of neovascular age-related macular degeneration (NV-AMD), pegaptanib became the first anti-VEGF therapy to receive regulatory approval for this condition. In view of the importance of VEGF in a variety of tissues, including the cardiovascular system and the retina, concerns have been raised as to the risks that might accompany VEGF inhibition. It is thus of particular note that pegaptanib has proved to have a favorable safety record in treating NV-AMD, with no ocular or systemic safety signals having emerged over more than 4 years of clinical studies. Accordingly, in addition to its use as a single agent, pegaptanib has demonstrated promise in combinatorial regimens that employ nonselective anti-VEGF agents as an initial treatment followed by maintenance therapy with pegaptanib. Pegaptanib has also shown encouraging preliminary results in the treatment of diabetic macular edema, proliferative diabetic retinopathy, and macular edema secondary to retinal venous occlusive conditions.

Age-related macular degeneration is the leading cause of vision loss in the developed world, with the expected number of affected elderly individuals reaching 17.8 million. Antivascular endothelial growth factor (anti-VEGF) injection therapy has been instrumental in treating a disease process that was previously thought to be untreatable. Over the past two decades, landmark studies have demonstrated the efficacy of different anti-VEGF medications and investigated the optimal dosing regimen and delivery mechanism to increase overall vision and minimise patient burden. In this review, we outline landmark neovascular age-related macular degeneration clinical trials that have demonstrated level 1 evidence for its usage or have contributed to the understanding of how to dose these agents.

BackgroundTo describe 10-year trends in visual outcomes, anatomical outcomes and treatment burden of patients receiving antivascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (nAMD).MethodsRetrospective cohort study of treatment-naïve, first-affected eyes with nAMD started on ranibizumab before January 1, 2009. The primary outcome was time to best-corrected visual acuity (BCVA) falling ≤35 ETDRS letters after initiating anti-VEGF therapy. Secondary outcomes included time to BCVA reaching ≥70 letters, proportion of eyes with BCVA ≥70 and ≤35 letters in 10 years, mean trend of BCVA and central retinal thickness over 10 years, and mean number of injections.ResultsFor our cohort of 103 patients, Kaplan-Meier analyses demonstrated median time to BCVA reaching ≤35 and ≥70 letters were 37.8 (95% CI 22.2 to 65.1) and 8.3 (95% CI 4.8 to 20.9) months after commencing anti-VEGF therapy, respectively. At the final follow-up, BCVA was ≤35 letters and ≥70 letters in 41.1% and 21%, respectively, in first-affected eyes, while this was the case for 5.4% and 48.2%, respectively, in a patient’s better-seeing eye. Mean injection number was 37.0±24.2 per eye and 53.6±30.1 at patient level (63.1% of patients required injections in both eyes).ConclusionsThe chronicity of nAMD disease and its management highlights the importance of long-term visual prognosis. Our analyses suggest that one in five patients will retain good vision (BCVA ≥70 ETDRS letters) in the first-affected eye at 10 years after starting anti-VEGF treatment; yet, one in two patients will have good vision in their better-seeing eye. Moreover, our data suggest that early treatment of nAMD is associated with better visual outcomes.

Purpose: This article studies visual outcome and frequency of antivascular endothelial growth factor (anti-VEGF) injections continued in patients with neovascular age-related macular degeneration (AMD) who had an earlier vitrectomy for postinjection endophthalmitis. Methods: A retrospective interventional study was conducted reviewing our database for patients with a diagnosis of endophthalmitis in the course of anti-VEGF injections. Endophthalmitis diagnosis was made on clinical examination of pain, rapid decrease in visual acuity (VA), conjunctival hyperemia, hypopyon, and vitritis. In all eyes, core vitrectomy with intravitreal antibiotics was performed. Spectral-domain optical coherence tomography was performed monthly before and after surgery during follow-up. Anti-VEGF injections were continued after surgery in all cases. Results: Eight eyes with postinjection endophthalmitis were included. Mean VA immediately before endophthalmitis was 20/50 Snellen with a mean of 19 intravitreal anti-VEGF injections ( P = .45). At time of endophthalmitis diagnosis, mean VA was 20/1000 (range, 20/2000-20/200). Mean time from injection to when the patient noted first symptoms was 4.3 days (range, 1-8 days). Mean time from first symptoms to surgery was 12 hours (range, 2.5-26 hours). Final mean VA at the end of follow-up (range, 12-84 months) did not statistically differ from VA at the visit immediately before endophthalmitis diagnosis ( P = .69). Mean frequency of injections after vitrectomy did not significantly differ from the presurgical course of treatment ( P =.97). Conclusions: Anti-VEGF treatment might be continued after vitrectomy for endophthalmitis and results in satisfactory anatomical and visual outcome. Surgery did not influence the frequency of anti-VEGF injections for neovascular AMD.

Choriocapillary loss is a major cause of neovascular age-related macular degeneration (NV-AMD). Although vascular endothelial growth factor (VEGF) blockade for NV-AMD has shown beneficial outcomes, unmet medical needs for patients refractory or tachyphylactic to anti-VEGF therapy exist. In addition, the treatment could exacerbate choriocapillary rarefaction, necessitating advanced treatment for fundamental recovery from NV-AMD. In this study, Tie2 activation by angiopoietin-2–binding and Tie2-activating antibody (ABTAA) presents a therapeutic strategy for NV-AMD. Conditional Tie2 deletion impeded choriocapillary maintenance, rendering eyes susceptible to NV-AMD development. Moreover, in a NV-AMD mouse model, ABTAA not only suppressed choroidal neovascularization (CNV) and vascular leakage but also regenerated the choriocapillaris and relieved hypoxia. Conversely, VEGF blockade degenerated the choriocapillaris and exacerbated hypoxia, although it suppressed CNV and vascular leakage. Together, we establish that angiopoietin-Tie2 signaling is critical for choriocapillary maintenance and that ABTAA represents an alternative, combinative therapeutic strategy for NV-AMD by alleviating anti-VEGF adverse effects.

ObjectiveStandard treatment of neovascular age-related macular degeneration (nAMD) is intravitreal injections (IVI) of antivascular endothelial growth factor (anti-VEGF) according to treat-and-extend (TnE). Observe-and-plan (OnP), a new regimen based on each individual’s relapse interval lead to fewer clinical visits and has so far shown to be safe in treatment-naïve patients. In this study, we explore patient satisfaction and safety in nAMD when switching from TnE to OnP.Methods and analysis38 participants treated acording to TnE for ≥12 months were included and switched from TnE to OnP with their last stable interval. Main outcome was patient satisfaction (Leeds Satisfaction Questionnaire). Secondary outcomes were best-corrected visual acuity (BCVA), central retinal thickness (CRT) before and 12 months after switch and number of monitoring visits and injections of anti-VEGF 12 months prior to and following switch.ResultsMean patient satisfaction was higher (3.7±0.5 SD) at 12 months after switch from TnE to OnP than before (3.6±0.5 SD, p=0.009, response rate 76%). BCVA and CRT were unchanged. Number of monitoring visits and injections were lower in the 12 months following than prior to switch (p<0.001).ConclusionA switch from TnE to OnP in a non-treatment-naïve population resulted in higher patient satisfaction, while maintaining stable BCVA. This indicates that OnP may be applicable in the large group of nAMD patients that have received IVI for several years. OnP may alleviate the treatment burden on both individual and society of frequent clinical visits while increasing patient satisfaction.
