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. Keywords: neovascular age-related macular degeneration, nAMD, "Treat-and-Extend", T&E, adherence, nonpersistence, anti-VEGF. For citation: Durasov A.B.

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.

AimTo report long-term outcomes on best-corrected visual acuity (BCVA) and treatment intervals with a treat-and-extend (T&E) regimen in patients with neovascular age-related macular degeneration (nAMD).MethodsThis observational study included treatment-naïve patients with nAMD, treated with aflibercept. A specific T&E protocol without a loading phase and predefined exit criteria was administered. After reaching predefined ‘exit-criteria’, the treatment period was complete, and patients were observed three monthly.ResultsEighty-two patients with a follow-up period of ≥2 years were included. BCVA (mean±SD, ETDRS letters) increased from 51.9±25.2 at baseline to 63.7±17.7 (p<0.0001) at 1 year, 61.7±18.5 (p<0.0001) at 2 years, 62.4±19.5 (p<0.0001, n=61) at 3 years and remained insignificantly higher than baseline at 4 years at 58.5±24.3 (p=0.22). Central subfield thickness (mean±SD, μm) decreased significantly from 387.5±107.6 (p<0.0001) at baseline to 291.9±65.5 (p<0.0001) at 1 year, and remained significantly lower until 4 years at 289.0±59.4 (p<0.0001). Treatment intervals (mean±SD, weeks) could be extended up to 9.3±3.1 weeks at 1 year and remained at 11.2±3.5 weeks at 4 years. Twenty-nine (35%) patients reached exit criteria and continued with three monthly observation only.ConclusionsAfter 4 years of treatment, initial vision gains were maintained with a reasonable treatment burden, even without an initial loading phase. Our results on functional outcomes are comparable with large controlled studies.

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.

Antivasoproliferative therapy is a revolutionary trend in the treatment of neovascular age-related macular degeneration (nAMD), as it is aimed at blocking growth factors of the newly formed vessels. Currently, two anti-VEGF drugs are registered for ophthalmological use, and the search for new molecules is only gaining momentum. Studying new approaches to treatment and developing innovative drugs, modern medicine relies on the data from international randomized clinical trials (RCT). The fact that this direction attracts much scientific interest is explained by high reliability of the data obtained with RCTs. However, when analyzing the effectiveness of anti-VEGF therapy in patients with nAMD in routine clinical practice, many ophthalmologists are confronted with discrepancies between the expected morphological and functional results as predicted by RCTs and those obtained in reality. It is thus important to bear in mind that RCTs simply determine how the dynamics of morphofunctional parameters should look like, whilst the ideal result is only achievable through correct implementation of therapeutic strategy in real clinical practice. The results obtained in the practice of any specialist wholly depend on how carefully the prescribed treatment protocols are followed by doctors and patients, how burdensome the treatment is, as well as on the potential of the medication. This literary review offers a comparative analysis of the results achieved by using anti-VEGF drugs (ranibizumab and aflibercept) obtained in key RCTs and in routine clinical treatment of nAMD patients.

Abstract Background To analyze the long-term effects of persistent subretinal fluid (SRF) on visual/anatomic outcomes according to the type of macular neovascularization (MNV) during relaxed treat-and-extend regimen with anti-vascular endothelial growth factor (anti-VEGF) agents in age-related macular degeneration (AMD) patients. Methods Patients with fovea-involving type 1 or type 2 MNV, treated with a relaxed treat-and-extend regimen for 2 years were retrospectively reviewed. Eyes with SRF observed more than three times per year were defined as the ‘persistent SRF (+) group’. To exclude the effects of IRF as much as possible, the eyes with persistent IRF were excluded. The effects of persistent SRF on the best-corrected visual acuity (BCVA), central subfield retinal thickness (CST), and changes in the photoreceptor layer (PRL) thickness and outer retinal bands (external limiting membrane, ellipsoid zone, and cone outer segment tip line) after anti-VEGF injection were analyzed for each MNV type. Results Seventy-seven eyes with type 1 MNV (44 eyes with persistent SRF) and 53 eyes with type 2 MNV (18 eyes with persistent SRF) were enrolled. Following a relaxed treat-and-extend regimen with anti-VEGF agents, BCVA and CST improved for each MNV type. In comparison between persistent SRF (+) and persistent SRF (−) group, there were no differences in the amount of change in BCVA and CST between the two groups for each MNV type during 2-year follow-up periods. In addition, there were no differences in the amount of reduction in PRL thickness and state of the outer retinal bands between the two groups for each MNV type. Conclusions Using a relaxed treat-and-extend regimen with anti-VEGF agents, persistent SRF did not have additional effects on visual and anatomic outcomes by 2 years, regardless of the MNV type.
