AimsTo evaluate the long-term functional and anatomical outcomes of neovascular age-related macular degeneration (nvAMD) treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF) for up to 10 years, and to identify associated risk factors.MethodsClinical and optical coherence tomography findings were retrieved for nvAMD cases treated with intravitreal anti-VEGF compounds using a treat-and-extend protocol. In addition, the major risk alleles for AMD in the CFH (rs1061170), HTRA1 (rs1200638) and C3 (rs2230199) genes were genotyped.ResultsFrom 276 eligible eyes in 206 patients, 80 eyes (29%) in 66 patients (32.0%) had a follow-up period of ≥8 years and were included in this study. Over a 10-year period, 73.3±28.0 (mean±SD) anti-VEGF injections were administered. Best-corrected visual acuity (BCVA; LogMAR) deteriorated from 0.55±0.53 at baseline to 1.00±0.73 at 10 years (p<0.0005). Central subfield thickness (CST) decreased from 415.8±162.1 µm at baseline to 323±113.6 µm (p<0.0005) after three monthly injections and remained lower than baseline throughout the follow-up period. Visual outcome was associated with BCVA and intraretinal fluid (IRF) at baseline, macular atrophy, and macular thinning at follow-up. The decrease in CST was inversely correlated with the number of CFH and/or C3 risk alleles carried by the patient (Pearson’s r: −0.608; p=0.003).ConclusionsPatients with nvAMD who received anti-VEGF therapy for 10 years developed substantial vision loss associated with the presence of IRF at baseline and macular atrophy. Major risk alleles for AMD in two complement genes were associated with a reduced long-term reduction in macular thickness.

History Of

BackgroundTo assess the prevalence and characteristics associated with macular atrophy (MA) in eyes with neovascular age-related macular degeneration (nAMD) treated with vascular endothelial growth factor (VEGF) inhibitors.MethodsThis was a retrospective, cross-sectional study of nAMD eyes that commenced anti-VEGF between January 2006 and August 2016. MA (absent/extrafoveal/subfoveal) was graded by treating practitioners based on multimodal imaging from April 2016. The prevalence of MA over time and risk factors of MA were assessed.ResultsThe prevalence of MA in a cohort of 1689 eyes was 9.9% (22/222) in eyes within 1 year of starting treatment, 41.5% (71/171) after 5 years and 48.4% (30/62) after 9 years of treatment. Risk factors for subfoveal MA included the proportion of visits at which the lesion was graded as inactive ((adjusted OR (AOR) 3.72 for the highest vs lowest the quartile of frequency of inactive gradings (95% CI 2.33 to 6.07)), age (AOR 1.05 per year (95% CI 1.02 to 1.07)), baseline visual acuity (AOR 3.9 for ≤35 letters vs ≥70 letters (95% CI 2.4 to 6.4)) and the number of injections received (AOR 1.20 every 10 injections (95% CI 1.08 to 1.33)). Similar associations were observed with extrafoveal MA.ConclusionsThe risk of MA appeared to drop in eyes that had not developed it within 5 years. Low choroidal neovascularisation activity was by far the strongest predictor. We could not determine whether the increased prevalence of MA with time was due to anti-VEGF treatment or the natural history of the condition.

Neovascular age-related macular degeneration (nAMD) is a progressive chronic multifactorial disease requiring long-term, lifelong anti- VEGF therapy. Treatment outcomes are not always in line with the results of randomized clinical trials and do not meet the expectations for therapy whose success is assessed differently by patients and physicians. Good functional and anatomical results are expected from antivasoproliferative therapy under certain conditions, e.g., accurate evaluation of some patient characteristics (baseline visual acuity, type of choroidal neovascularization, comorbidities, status of retinal fluid and its differentiation), timely (as early as possible) treatment initiation after verifying diagnosis, and strict adherence to a proactive personalized "Treat-and-Extend" (T&E) regimen that implies a required number of injections with individual intervals. Poor adherence to treatment (non-compliance or nonpersistence of anti-VEGF therapy) significantly affects treatment outcomes in real-world clinical practice. This paper reviews criteria which predict the response to antivasoproliferative therapy and improving treatment adherence. The authors describe four fundamental principles to be met by an ideal regimen of anti-VEGF therapy for nAMD.

PurposeTo analyse the morphological characteristics of eyes with neovascular age-related macular degeneration (AMD) with good long-term visual acuity after anti-VEGF (vascular endothelial growth factor) therapy.MethodsRetrospective, observational study of 175 patients with neovascular AMD with >5 years of follow-up after initiating anti-VEGF therapy. Spectral-domain optical coherence tomography images were assessed for thickness of pigment epithelial detachment (PED), subretinal hyper-reflective material (SHRM), subretinal fluid and subfoveal choroidal, as well as the integrity of the outer retinal bands.ResultsThe final analysis cohort included 203 eyes (175 patients) followed for a mean of 7.84±1.70 years (range: 5–11). The maximum PED thickness in the foveal central subfield (FCS) was significantly lower (p<0.001) in the poor vision group (13.11 μm) compared with the intermediate (86.25 μm) or good (97.92 μm) vision groups, respectively. In contrast, the maximum thickness of SHRM in the FCS was significantly thicker (p<0.001) in eyes with poor vision (149.46 μm) compared with eyes with intermediate vision (64.37 μm) which in turn were significantly thicker (p<0.001) than eyes with good vision (9.35 μm). The good vision group also had better continuity of all outer retinal bands (external limiting membrane, ellipsoid zone, and retinal pigment epithelium) compared with the other two groups (all p<0.001).ConclusionA thicker PED and thinner SHRM were correlated with better vision in eyes with neovascular AMD following long-term anti-VEGF therapy. If replicated in future prospective studies, these findings may have implications for design of optimal anatomic endpoints for neovascular AMD treatment.

Purpose. To evaluate the predictive factors of long-term visual outcomes in neovascular age-related macular degeneration (nAMD) treated with antivascular endothelial growth factor (anti-VEGF) agents. Methods. Unicentric retrospective review of patients with nAMD treated with anti-VEGF agents. Visual outcomes, 12 and 60 months after diagnosis, were evaluated. In an attempt to identify predictive factors of visual outcomes, multiple variables (demographic and epidemiological characteristics, angiographic and tomographic features) were analyzed, at baseline and during follow-up. Results. One hundred and seventeen patients were included. In multivariate analysis, baseline best-corrected visual acuity was associated with all visual endpoints at 12 and 60 months. Additionally, age, gender, number of injections, and development of subretinal fibrosis during follow-up were also significant predictors of visual outcomes at 60 months. Conclusions. Several factors can be useful in clinical practice as predictors of visual outcomes in response to anti-VEGF treatment of nAMD.

Age-related macular degeneration (AMD) is the leading cause of substantial and irreversible vision loss amongst elderly populations in industrialized countries. The advanced neovascular (or “wet”) form of the disease is responsible for severe and aggressive loss of central vision. Current treatments aim to seal off leaky blood vessels via laser therapy or to suppress vessel leakage and neovascular growth through intraocular injections of antibodies that target vascular endothelial growth factor (VEGF). However, the long-term success of anti-VEGF therapy can be hampered by limitations such as low or variable efficacy, high frequency of administration (usually monthly), potentially serious side effects, and, most importantly, loss of efficacy with prolonged treatment. Gene transfer of endogenous antiangiogenic proteins is an alternative approach that has the potential to provide long-term suppression of neovascularization and/or excessive vascular leakage in the eye. Preclinical studies of gene transfer in a large animal model have provided impressive preliminary results with a number of transgenes. In addition, a clinical trial in patients suffering from advanced neovascular AMD has provided proof-of-concept for successful gene transfer. In this mini review, we summarize current theories pertaining to the application of gene therapy for neovascular AMD and the potential benefits when used in conjunction with endogenous antiangiogenic proteins.
