Schranz M, Bogunovic H, Deak G, Sadeghipour A, Reiter GS, Schmidt-Erfurth U. Linking disease activity with optical coherence tomography angiography in neovascular age related macular degeneration using artificial intelligence. Sci Rep 2024; 14:19278. [PMID: 39164449 PMCID: PMC11336074 DOI: 10.1038/s41598-024-70234-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Accepted: 08/14/2024] [Indexed: 08/22/2024] Open
Abstract
To investigate quantitative associations between AI-assessed disease activity and optical coherence tomography angiography (OCTA)-derived parameters in patients with neovascular age-related macular degeneration (nAMD) undergoing anti-VEGF therapy. OCTA and SD-OCT images obtained from multicenter, randomized study data were evaluated. A deep learning algorithm (RetInSight) was used to detect and quantify macular fluid on SD-OCT. Mixed effects models were applied to evaluate correlations between fluid volumes, macular neovascularization (MNV)-type and OCTA-derived MNV parameters; lesion size (LS) and vessel area (NVA). 230 patients were included. A significant positive correlation was observed between SRF and NVA (estimate = 199.8 nl/mm2, p = 0.023), while a non-significant but negative correlation was found between SRF and LS (estimate = - 71.3 nl/mm2, p = 0.126). The presence of Type I and Type II MNV was associated with significantly less intraretinal fluid (IRF) compared to Type III MNV (estimate type I:- 52.1 nl, p = 0.019; estimate type II:- 51.7 nl, p = 0.021). A significant correlation was observed between pigment epithelial detachment (PED) and the interaction between NVA and LS (estimate:28.97 nl/mm2; p = 0.012). Residual IRF at week 12 significantly correlated to baseline NVA (estimate:38.1 nl/mm2; p = 0.015) and LS (estimate:- 22.6 nl/mm2; p = 0.012). Fluid in different compartments demonstrated disparate associations with MNV OCTA features. While IRF at baseline was most pronounced in type III MNV, residual IRF was driven by neovascular MNV characteristics. Greater NVA in proportion to LS was associated with higher amounts of SRF and PED. The correlation between these parameters may represent MNV maturation and can be used as a biomarker for resolution of disease activity. AI-based OCT analysis allows for a deeper understanding of neovascular disease in AMD and the potential to adjust therapeutic strategies to optimize outcomes through precision medicine.

Abstract
PURPOSE This study evaluated the long-term outcomes of eyes with neovascular age-related macular degeneration (nAMD) treated with aflibercept according to a treat-and-extend (T&E) regimen for up to 5 years. Methods This retrospective study included 112 eyes of 111 patients with nAMD who received aflibercept according to the T&E regimen. The patients received 3 monthly injections of aflibercept followed by a T&E regimen for at least 12 months. Data, including best-corrected visual acuity (BCVA), treatment interval, presence of exudation, central retinal thickness, and central choroidal thickness were analyzed. RESULTS Of the 112 consecutive eyes, 66 completed the 5-year follow-up. After 5 years of treatment, BCVA (logMAR) was significantly better than baseline (0.29 ± 0.31 at baseline and 0.18 ± 0.23 at 5 years, P < 0.01). A mean of 7.0 ± 1.5 injections in the first year and 4.9 ± 2.2 injections per year thereafter were required. In eyes with subretinal hyperreflective material (SHRM) at baseline, BCVA at baseline and 5 years were significantly worse than in eyes without SHRM at baseline and 5 years. However, the eyes with SHRM required fewer injections and exhibited greater BCVA improvement. CONCLUSION This retrospective study demonstrated the effectiveness of the T&E regimen with aflibercept in managing nAMD over a 5-year period, maintaining significant improvements in BCVA.

Abstract
Age-related macular degeneration (AMD) is one of the main causes of visual acuity (VA) loss in people over 50 years of age worldwide, with neovascular AMD (nAMD) accounting for 80% of cases of severe vision loss due to this disease. Anti-vascular endothelial growth factor (anti-VEGF) drugs have been used for the treatment of this disease for more than a decade, changing drastically the visual prognosis of these patients. However, initial studies reporting data on outcomes were short term. Currently, there are different series published on the long-term results of AMD after treatment with anti-VEGF, and the aim of this review is to synthesize these results. The mean follow-up of the included studies was 8.2 years (range 5-12 years). The mean initial VA was 55.3 letters in the Early Treatment Diabetic Retinopathy Study (ETDRS) (range 45.6-65) and the mean final VA was 50.1 letters (range 33.0-64.3), with a mean loss of 5.2 letters. At the end of follow-up, 29.4% of the patients maintained a VA > 70 letters. The 67.9% of patients remained stable at the end of follow-up (< 15 letter loss), with a severe loss (≥ 15 letters) of 30.1%. Fibrosis and atrophy were the main causes of long-term VA loss, occurring at the end of follow-up in 52.5% and 60.5%, respectively.

Abstract
BACKGROUND/AIMS To analyse long-term outcomes of antivascular endothelial growth factor (anti-VEGF) therapy for the treatment of neovascular age-related macular degeneration (nAMD) using pro re nata (PRN) regimen in a single-centre clinical practice. METHODS All patients receiving intravitreal injection (IVI) for nAMD between 1 January 2008 and 31 December 2020 were searched from electronic medical records. All 3844 treatment-naïve eyes of 3008 patients were included with a total of 50 146 IVIs (87% bevacizumab) administered. Main outcome measures were mean change in visual acuity (VA) from baseline, proportion of eyes within 15 letters of baseline, proportion of eyes with VA ≥20/40 Snellen and ≤20/200 Snellen, number of annual visits and number of annual IVIs. RESULTS The mean baseline VA was 55 Early Treatment Diabetic Retinopathy Study (ETDRS) letters and the mean change in VA from baseline was +2, +2, ±0, -2, -2 and -4 ETDRS letters at year 1, 2, 3, 5, 7 and 10, respectively. Proportions of eyes within 15 letters of baseline were 88%, 87%, 82%, 80%, 76% and 72% at the end of years 1, 2, 3, 5, 7 and 10, respectively. The median number of annual IVI was 6 at years 1-7 and 5 at year 10. The median number of annual total visits was 10 at year 1, 9 at years 2-7 and 8 at year 10, respectively. CONCLUSIONS VA was maintained short-term and long-term with anti-VEGF therapy using PRN treatment regimen.

Clin Ophthalmol 2023; 17:1465-1474. [PMID: 37256195 PMCID: PMC10226541 DOI: 10.2147/opth.s409103] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 05/12/2023] [Indexed: 06/01/2023] Open
Abstract
Purpose Patients with neovascular age-related macular degeneration (nAMD) are treated with frequent intravitreal injections to maintain vision. The treatment frequency impacts the life of patients and caregivers and poses a major capacity challenge for Norwegian ophthalmic clinics. The purpose of this survey was to document patient-reported outcomes on how the disease and the treatment impact nAMD patients in Norway. Methods Norwegian nAMD patients voluntarily completed the survey. The patients reported the time spent on each treatment appointment, the need for caregiver support, treatment intervals, and the emotional impact of the treatment. There was no active selection of patients to the survey. Respondents had to confirm the nAMD diagnosis prior to submitting the response. All data was included in the analysis as submitted by the respondents. This survey was market research involving anonymous patient data, and no participants were identifiable. Results In total, 130 patients responded to the survey. The majority of patients reported to receive nine or more injections per year (48.8%), and many patients needed caregiver support for every treatment appointment (37.7%). Patients reported to be anxious one day (25.4%), two days (8.5%), one week (10.8%) or more than one week (3.1%) prior to treatment. The week before the treatment, 33.1% of patients reported to be stressed and 15.4% struggled to sleep. The majority of patients reported the treatment as uncomfortable (54.6%) or as somewhat painful (26.2%). The results on yearly number of injections, time used each treatment day and need for caregiver support suggested a variation between Norwegian hospital regions. Conclusions This survey uncovers how treatment with intravitreal injections represents a substantial burden for Norwegian patients with nAMD. Future research on how the treatment burden impacts nAMD patients may lead to more patient-centered care and help guide treatment decisions. New treatments with longer intervals between injections are likely to both reduce the treatment burden and improve capacity in ophthalmology clinics.

Abstract
PURPOSE The purpose is to study the 5-year results of aflibercept monotherapy using an individualized regimen in naïve patients with neovascular AMD (nAMD). MATERIALS AND METHODS This is a prospective observational study including naïve nAMD patients who underwent aflibercept injections with at least 5 years of follow-up. All of them received 3 monthly injections at the loading phase, followed by an observation period, then treated with an individualized treat-and-extend regimen. Visual acuity (VA) measurement and optical coherence tomography were performed at each visit. RESULTS Forty-eight eyes were included. Of these, 30 were followed up for 5 years. The mean follow-up was 61.7 ± 2.3 months. The mean age was 81 ± 8 years. The visual gain was 7.3 ± 12.7 letters at 1 year, 6.5 ± 12.5 letters at 2 years, 5.2 ± 17 letters at 3 years, 6.2 ± 18.6 letters at 4 years, and 5.6 ± 20 letters at 5 years. At the last observation, 53% of eyes had VA > 70 letters. A complete fluid resolution was obtained in 53% of the eyes. At the 5-year endpoint, the total number of injections was 21.6 ± 13.4. Macular atrophy was observed in 18 eyes (60%) and subretinal fibrosis in 14 eyes (46%). CONCLUSION Patients with exudative AMD can maintain their visual function at 5 years with aflibercept using an individualized treatment. The loss of visual gain beyond 2 years could be related to the natural progression of the disease than the direct effect of anti-vascular endothelial growth injections.

Abstract
BACKGROUND Anti-vascular endothelial growth factor (VEGF) therapy is currently the most effective therapy of exudative age-related macular degeneration (AMD). The aim of this study was to assess long-term benefits of intensive aflibercept and ranibizumab anti-VEGF therapy in patients with exudative AMD. METHODS Two clinical trial sites recruited their original subjects for a re-evaluation 7 years after the baseline visit of the phase-3 Vascular Endothelial Growth Factor (VEGF) Trap-Eye: Investigation of Efficacy and Safety in Wet Age-Related Macular Degeneration (VIEW 2) trial. Forty-seven eyes of 47 patients with AMD originally treated with ranibizumab (14 eyes) or aflibercept (33 eyes) were included. RESULTS Mean number of injections was 17.8 ± 3.0 during participation in the VIEW 2 trial. Fourteen of 47 (30%) eyes were given additional injections with a mean number of 5.7 ± 4.5 after the trial. At a mean follow-up time of 82 ± 5 months best corrected visual acuity (BCVA) remained stable or improved (≤ 10 letters lost) in 55% of patients in the entire study population, in 43% in the ranibizumab group and in 60% in the aflibercept group. In both groups combined mean BCVA was 54 ± 13 letters at baseline, 65 ± 17 letters at the end of the intensive phase and 45 ± 25 letters at the end of follow-up. There was no statistically significant difference in BCVA between the two groups at baseline (p = 0.88) and at the end of follow-up (p = 0.40). Macular atrophy was observed in 96% of eyes, average area was 7.22 ± 6.31 mm2 with no statistically significant difference between groups (p = 0.47). Correlation between BCVA at end-of-follow-up and the area of atrophy was significant (p < 0.001). At the end of follow-up, fluid was detected in 7 of 47 eyes (15%) indicating disease activity. CONCLUSION Long-term efficacy of aflibercept and ranibizumab was largely consistent. Following a two-year intensive therapy with as-needed regimen, BCVA was maintained or improved in almost half of the patients and in the ranibizumab group and more than half of the patients in the aflibercept group with very few injections. In a remarkable proportion of eyes, BCVA declined severely which underlines the need for long-term follow-ups and may indicate a more prolonged intensive therapy. TRIAL REGISTRATIONS VIEW 2 study: ClinicalTrials.gov ID: NCT00637377, date of registration: March 18, 2008. Long-term follow-up: IRB nr.: SE RKEB 168/2022, ClinicalTrials.gov ID: NCT05678517, date of registration: December 28, 2022, retrospectively registered.

Abstract
PURPOSE To compare the visual and anatomical outcomes between strict pro re nata (strict PRN) and treat-and-extend (T&E) anti-vascular endothelial growth factor (anti-VEGF) regimens for neovascular age-related macular degeneration (nAMD). METHODS A meta-analysis of 1-year and 2-year changes between strict PRN and T&E anti-VEGF regimens were conducted in both randomized controlled trials (RCTs) and real-world studies (RWSs). The best-corrected visual acuity (BCVA), central retinal thickness (CRT), and weighted mean numbers of visits and injections were evaluated. RESULTS A total of 19 RCTs and 23 RWSs (2,530 eyes in strict PRN and 4,399 eyes in T&E) were included. Mean BCVA change in strict PRN group in both 1-year and 2-year (5.95 and 5.78, respectively) was noninferior to the T&E group (7.85 and 5.96, respectively). Mean CRT changes were also similar in both strict PRN and T&E groups. Mean number of visits were significantly more in the strict PRN group, whereas mean number of injections was significantly more in the T&E group. CONCLUSION The strict PRN regimen demonstrates a noninferior BCVA improvement to the T&E regimen, achieving fewer injections, and may be both economically and medically beneficial. Both selections should be provided to patients with an overall consideration.

Abstract
INTRODUCTION Age-related macular degeneration (AMD) is a major cause of central visual loss in the developed world. Although the pathogenesis is not fully understood, vascular endothelial growth factor (VEGF) is considered the most important growth factor involved in angiogenesis and exudation in neovascular AMD eyes. Advances in anti-VEGF agents have changed the treatment approach for wet AMD, allowing better outcomes in visual acuity and retinal anatomy. AREAS COVERED The present review describes the main pharmacological and clinical characteristics of anti-VEGF drugs, focusing firstly on the molecules commonly in use and then on the new candidate therapies. We performed a comprehensive literature search using the PubMed database from 1 January 1993 to 1 June 2022, with search terms including anti-VEGF, biosimilar, neovascular macular degeneration, AMD, and safety. EXPERT OPINION The management of AMD is still onerous for both the physician and patient due to the great number of required injections. Current research is underway to resolve not only the economic burden but also the discomfort of patients, aiming to develop a drug with a different or a multiple target, increasing the potency whilst maintaining a good safety profile. Furthermore, clinical research is currently investigating different forms of drug administration.

Abstract
PURPOSE The study analyzes long-term (three years) clinical effectiveness of anti-VEGF treatment of neovascular age-related macular degeneration (nAMD) and attempts to identify the most clinically significant associations between the functional and structural parameters. MATERIAL AND METHODS The study included 122 patients (122 eyes) diagnosed with nAMD, mean age -73.4±6.6 years old. Prospective follow-up lasted 144 weeks. All patients were treated with angiogenesis inhibitor (aflibercept 2 mg), and most of them (72.9%) - according to the Treat-and-Extend protocol. RESULTS The average number of injections was 7.39±1.28, 4.63±0.97 and 4.06±0.81 during the first, second and third years of the follow-up, respectively. The mean baseline best-corrected visual acuity (BCVA) was 0.24±0.21. After three loading doses, BCVA increased to 0.33±0.26 (+0.09; 37.5%), by the end of follow-up BCVA was 0.35±0.27 (+0.11; 45.8%). Central retinal thickness (CRT) decreased from 314.89±88.07 μm to 234.4±42.8 μm (a 25.5% decrease) by the end of the follow-up. After three loading injections baseline functional and anatomical parameters had the most significant correlations (r≥0.7, p<0.05) with intraretinal fluid, ellipsoid zone integrity and the area of macular atrophy. CONCLUSIONS Analysis of the morphological and functional outcomes by the end of the first year demonstrates the feasibility of preserving the results while reducing the number of visits and injections according to the Treat-and-Extend protocol. Achieving maximum improvement of functional parameters most significantly correlated with changes in such biomarkers as central retinal thickness, area of macular atrophy and integrity of the ellipsoid zone.

Br J Ophthalmol 2022; 106:1555-1560. [PMID: 34083208 DOI: 10.1136/bjophthalmol-2021-319054] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 04/04/2021] [Accepted: 04/30/2021] [Indexed: 11/03/2022]
Abstract
AIMS To 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. METHODS Clinical 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. RESULTS From 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). CONCLUSIONS Patients 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.

Transition from Laser to Intravitreal Injections for Diabetic Retinopathy: Hospital Utilization and Costs from an Extended Healthcare Perspective. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12603. [PMID: 36231903 PMCID: PMC9564656 DOI: 10.3390/ijerph191912603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 09/26/2022] [Accepted: 09/28/2022] [Indexed: 06/16/2023]
Abstract
PURPOSE To describe the trends in hospital utilization and economic outcomes associated with the transition from laser to intravitreal injection (IVI) therapy for diabetic retinopathy (DR) at Oslo University Hospital (OUH), which provides the largest retina service in Norway. METHODS This descriptive study analyzed hospital administrative data and determined the average utilization and treatment proportions of laser therapy, IVIs and vitrectomy for each patient per year. The Chi-square test was used to compare resource use between treatment groups. From an extended healthcare perspective, the annual cost per patient was calculated using Norwegian tariff data from 2020 and the National Medication Price Registry for patients seen between 2010 and 2018. Bootstrapping was performed to generate 95% confidence intervals for the cost per patient per year. RESULTS Among the 1838 (41% female) patients treated for DR between 2005 and 2018, OUH provided on average 1.09 laser treatments per DR patient and 0.54 vitrectomies per DR patient in 2005, whose utilization declined to 0.54 and 0.05 treatments per DR patient, respectively, by 2018. Laser treatments declined from 64% to 10%, while vitrectomies declined from 32% to 1%. In contrast, IVI treatments increased from 4.5% to 89% of the total share, representing an average increase, from 0.08 injections per patient in 2005 to 4.73 injections per patient in 2018. Both the increasing number of DR patients and the shift in the type of treatment increased the economic costs of treating DR from a total of EUR 0.605 million (EUR 2935 per patient) in 2010 to EUR 2.240 million (EUR 3665 per patient) in 2018, with IVIs contributing considerably to these costs. CONCLUSIONS Despite the decline in the use of vitrectomies, the transition from laser to IVI therapy for DR increased the healthcare resource utilization and economic costs of its treatment over the observed time. A main cost driver was the need for long-term IVIs, in addition to the drug cost itself. Trade-offs can be achieved through effective alternative IVI delivery or appropriate drug choice that balances patient needs with the economic burden of treating DR.

Abstract
BACKGROUND AND OBJECTIVES This study's objective was to describe long-term visual outcomes of patients with age-related macular degeneration (AMD) treated with intravitreal anti-vascular endothelial growth factor injections who were lost to follow-up and then resumed treatment with anti-vascular endothelial growth factor injections. MATERIALS AND METHODS This was a retrospective cohort study of eyes with at least 7 years of follow-up following the initiation of treatment for wet AMD with and without gaps in therapy. RESULTS The baseline mean logMAR visual acuity was 0.65 ± 0.5 (Snellen acuity 20/89) in eyes with gaps in therapy and 0.53 ± 0.3 (20/68) in eyes without gaps. In the initial 7-year follow-up period, the eyes with gaps in therapy had significantly worse visual acuity (P < .001) and this remained significant when accounting for baseline visual acuity (P < .001). CONCLUSIONS Gaps in intravitreal injection therapy for exudative AMD were negatively associated with visual acuity. Adherence to therapy is important to address in the care of patients with exudative AMD. [Ophthalmic Surg Lasers Imaging Retina 2022;53:481-489.].

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
INTRODUCTION To assess the long-term effectiveness of a treat-and-extend (T&E) anti-vascular endothelial growth factor regimen in patients with neovascular age-related macular degeneration who remain on T&E and those switched from once-monthly (OM) dosing to T&E (OM-T&E). METHODS In this 12-month extension of the 2-year CANTREAT study, patients received intravitreal ranibizumab 0.5 mg in a T&E regimen. Main outcome measures included mean change in best-corrected visual acuity (BCVA) from baseline and from month 24 to month 36; percentages of patients who gained ≥5, ≥10, or ≥15 Early Treatment of Diabetic Retinopathy Study (ETDRS) letters or lost ≥5, ≥10, or ≥15 letters from baseline and from month 24 to month 36; and number of injections administered from baseline and from month 24 to month 36 for both groups. RESULTS Of the 139 patients (73 T&E, 66 OM-T&E) in the extension, 121 (68 T&E, 53 OM-T&E) completed 36 months. Mean (standard deviation [SD]) BCVA changes from baseline to the extension last visit (month 33-36) were +6.6 (11.4) letters in the T&E group and +4.8 (14.3) letters in the OM-T&E group, representing maintenance of 24-month gains. The mean (SD) numbers of injections during the extension were 7.3 (2.7) for T&E and 7.1 (2.8) for OM-T&E. DISCUSSION/CONCLUSION These findings suggest that after 36 months of treatment, the mean BCVA improvement achieved at 24 months is maintained for both the patients exclusively treated with the T&E regimen and those that switched to T&E after 24 months in the OM regimen.

Risk factors for emerging intraocular inflammation after intravitreal brolucizumab injection for age-related macular degeneration. PLoS One 2021; 16:e0259879. [PMID: 34871313 PMCID: PMC8648104 DOI: 10.1371/journal.pone.0259879] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2021] [Accepted: 10/29/2021] [Indexed: 12/31/2022] Open
Abstract
Purpose To analyze the risk factors associated with emerging intraocular inflammation (IOI) after intravitreal brolucizumab injection (IVBr) to treat age-related macular degeneration (AMD). Methods This study included 93 eyes of 90 patients. The incidence of emerging IOI was analyzed. The patients were classified into IOI or non-IOI groups, and background clinical characteristics in each group were compared. Results IOI occurred in 14 eyes of 14 cases (16%; five women, nine men [5:9]; IOI group) after IVBr; contrastingly, no IOI occurred in 76 patients (10 women, 66 men [10:66]; non-IOI group). The mean ages in IOI and non-IOI groups were 79.4 ± 8.1 and 73.8 ± 8.9 years old, respectively, and the average age in the IOI group was significantly higher than that in the non-IOI group (P = 0.0425). In addition, the percentages of females in the IOI and non-IOI groups were 43% and 13%, respectively, and IOI occurred predominantly in females (odds ratio: 4.95, P = 0.0076). Moreover, the prevalence of diabetes in the IOI and non-IOI groups was 64% and 32%, respectively, with a significant difference (odds ratio: 3.90, P = 0.0196). In contrast, the prevalence of hypertension in the IOI and non-IOI groups was 36% and 57%, respectively, with no significant difference (P = 0.15). Conclusion The comparison of clinical profiles of IOI or non-IOI cases in IVBr treatment for AMD suggests that the risk factors for IOI are old age, female sex, and history of diabetes; however, IOI with vasculitis or vascular occlusion in this cohort does not seem to cause severe visual impairment. Further studies are required to investigate potential risk factors for IOI.

Abstract
Purpose To report the results of anti-vascular endothelial growth factor (VEGF) therapy using treat-and-extend (TAE) and treatment cessation regimens for exudative age-related macular degeneration (AMD) and pachychoroid neovasculopathy (PN). Methods We retrospectively studied 101 treatment-naïve eyes of 101 patients with exudative AMD and PN that underwent anti-VEGF therapy using TAE and treatment cessation regimen with a follow-up period of ≥12 months. Best-corrected visual acuity (BCVA), treatment frequency, and number of eyes with successful treatment cessation were measured. Successful treatment cessation was defined as dry macula retention without treatment for >16 weeks after the last injections. Factors related to the successful treatment cessation were evaluated. Results BCVA was maintained at the last visit with a mean follow-up period of 49.9 ± 26.9 months. The injection number decreased from 6.8 ± 2.31 at the first year to 3.7 ± 3.64 at the fifth year. At the last visit, 48 (47.5%) eyes were being treated at an interval of ≥12 weeks or were under treatment cessation. Successful treatment cessation during the follow-up period and at the last visit were achieved in 56 (55.4%) and 27 (26.7%) eyes, with a median treatment-free period of 66 and 126 weeks, respectively. Good early treatment response and a small recurrence number were associated with successful treatment cessation at the last visit. Conclusion Patients with good early response to treatment and fewer recurrences may achieve treatment cessation. This information could help physicians predict the achievement of treatment cessation for a considerable period.

Cost-minimisation analysis of a treat-and-extend regimen with anti-VEGFs in patients with neovascular age-related macular degeneration. Graefes Arch Clin Exp Ophthalmol 2021; 260:1083-1095. [PMID: 34643793 PMCID: PMC8511619 DOI: 10.1007/s00417-021-05359-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 07/16/2021] [Accepted: 07/27/2021] [Indexed: 12/02/2022] Open
Abstract
Purpose Although intraocular anti-vascular endothelial growth factors (anti-VEGFs) are effective as treatment of neovascular age-related macular degeneration (nAMD), the (economic) burden on the healthcare system is considerable. A treat-and-extend (T&E) regimen is associated with a lower number of injections without compromising the effectiveness and can therefore help optimise nAMD treatment. This study investigates the per-patient costs associated with nAMD treatment, when using aflibercept, bevacizumab, or ranibizumab with a T&E regimen. Methods In this cost-minimisation model, the per-patient costs in the Netherlands were modelled using a healthcare payers’ perspective over a 3-year time horizon with the assumption that efficacy of treatments is similar. Additionally, the break-even price of the different anti-VEGFs was calculated relative to the cheapest option and injection frequency. Results The injection frequency varied from 14.2 for aflibercept to 27.4 for bevacizumab in 3 years. Nonetheless, bevacizumab remains the cheapest treatment option (€14,215), followed by aflibercept (€18,202) and ranibizumab (€31,048). The medication covers the majority of the per-patient costs for aflibercept and ranibizumab, while administration covers the majority of the per-patient costs for bevacizumab. The break-even prices of aflibercept and ranibizumab are respectively €507 and €60.58 per injection. Brolucizumab was included in the scenario analysis and was more expensive than aflibercept (€20,446). Brolucizumab should reduce to 13.8 injections over 3 years to be as costly as aflibercept. Conclusion Bevacizumab is the cheapest anti-VEGF treatment. The list prices of all anti-VEGFs should reduce to be as costly as bevacizumab. Aflibercept is the second-choice treatment and so far brolucizumab is not.

Front Med (Lausanne) 2021; 8:706084. [PMID: 34540863 PMCID: PMC8446694 DOI: 10.3389/fmed.2021.706084] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 08/13/2021] [Indexed: 12/01/2022] Open
Abstract
The use of anti-vascular-endothelial growth factor agents for neovascular age-related macular degeneration (nAMD) in different treatment schemes is widely common in clinical practice. However, there is currently limited data on the long-term outcomes of a strict treat-and-extend regimen (TER) and imaging biomarkers to predict both functional outcome and the potential for a TER exit due to success. In this retrospective study we followed treatment-naïve subjects with nAMD starting treatment with either ranibizumab or aflibercept in a TER without loading dose but with predefined exit criteria for up to 8 years. We evaluated both the functional outcome and several spectral-domain optical coherence tomography parameters in a follow-up mode using a standardized protocol. Within the 211 eyes followed for a mean of 60.3 ± 20.9 months, follow-up adherence was high with major part of discontinuations of TER being due to success. Mean best-corrected visual acuity (BCVA) increased from initially 63.9 ± 15.5 ETDRS letters to 70.0 ± 14.7 after 1 year (+6.1 letters, p < 0.001) and to 68.5 ± 18.1 (+4.6 letters, p = 0.028) at 5 years. A worse BCVA (p = 0.001) and a better external limiting membrane (ELM) disruption score at baseline predicted (p = 0.019) BCVA gain at 5 years. The probability of reaching the exit criteria was significantly associated with a better ELM disruption score (p = 0.044) and the absence of a central pigment epithelial detachment (PED) (p = 0.05) at baseline. Significant visual gains were sustained in a long-term TER in a real-world setting. Integrity of ELM at baseline predicted BCVA gain at 5 years and the potential for TER exit due to success.

Abstract
Purpose: The aim of this study was to report the 10-year visual outcome in eyes treated with anti-vascular endothelial growth factor (anti-VEGF) agents for neovascular age-related macular degeneration (nAMD) and to assess the impact of switching treatment as part of routine clinical care. Methods: Electronic records of treatment-naïve eyes initiated on intravitreal ranibizumab between January and December 2009 were accessed. The primary outcome measured was the change in visual acuity (VA) in Early Treatment of Diabetic Retinopathy Study letters. The frequency and reasons for treatment discontinuation during each year of follow-up and the impact of switching from ranibizumab to aflibercept were some of the secondary outcomes. Results: Of the 223 eyes (203 patients), 60 eyes completed 10 years of continuous follow-up. After a mean follow-up of 121.4 months, VA declined by 5.6 letters (95% confidence interval [CI] –0.25 to –11.1, P = 0.04). Final VA of ≥70 letters was seen in 20% of eyes and 35% had VA ≤ 35 letters. VA gain of ≥10 letters was seen in 23% and loss of ≥10 letters was seen in 40% of the eyes. Twenty-nine eyes remained on ranibizumab monotherapy and 31 switched to aflibercept. Switched eyes showed a visual decline of 7.1 letters (5.5 letters in monotherapy eyes, P = 0.32) and received a significantly higher number of injections (39.6 ± 9.9 vs. 24.4 ± 13.1, P < 0.0001). Patients discontinuing treatment were older and had lower baseline vision compared to completers. Conclusion: VA declined below the baseline after 10 years of follow-up and switching did not have any effect on the final visual outcome.

The Effect of Treatment Discontinuation During the COVID-19 Pandemic on Visual Acuity in Exudative Neovascular Age-Related Macular Degeneration: 1-Year Results. Ophthalmol Ther 2021; 10:935-945. [PMID: 34374028 PMCID: PMC8351565 DOI: 10.1007/s40123-021-00381-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 07/23/2021] [Indexed: 01/08/2023] Open
Abstract
Introduction To evaluate the effect of a 9-week treatment deferral due to healthcare restrictions caused by Austria’s first governmental lockdown associated with the coronavirus disease 2019 (COVID-19) pandemic on visual acuity (VA) in eyes compromised by exudative neovascular age-related macular degeneration (nAMD) after 1 year. Methods Retrospective data collection of 98 eyes (98 patients) with a treatment discontinuation at a tertiary eye care center (Clinic Landstraße, Vienna Healthcare Group, Austria) between March 16 and May 4, 2020. Prior to the lockdown, patients received multiple intravitreal injections (IVI) of anti-vascular endothelial growth factor with a personalized treatment interval for 3 years on average and at least three IVI after the lockdown. Results When the treatment interval doubled to 117.6 ± 31.4 days in spring 2020, patients lost 2.2 ± 4.6 ETDRS letters (p = 0.002) on average before reinitiating therapy. In total, 4.1 ± 8.1 letters (p < 0.0001) were lost despite continuous individual re-treatment over the course of the next year. In a univariate analysis, the extended interval time remained statistically significant (p < 0.0001), indicating a larger VA reduction within intervals with increasing interval time in days. Conclusion The short-term treatment interruption had a persistent negative impact on the VA course of eyes under therapy after 1 year. Continuous therapy independent of the underlying treatment regimen remains of utmost importance in exudative nAMD. Our data should create awareness to regulators regarding future decisions despite the global pandemic. Supplementary Information The online version contains supplementary material available at 10.1007/s40123-021-00381-y. Age-related macular degeneration (AMD) is the leading cause of legal blindness in developed countries. Wet AMD refers to the existence of new vessel growth in the macular, the part of the retina with the highest concentration of photoreceptors and hence the best visual acuity. The gold standard therapy of wet AMD consists of repeated injections of an antibody against new vessel formation into the eye to stabilize the disease. The sudden break of a treatment regimen for an individual person has never been investigated as it is ethically not acceptable. The coronavirus disease 2019 (COVID-19) pandemic and its associated lockdown led to an emerging situation in spring, 2020. We were forced by governmental restrictions to minimize contact with the most vulnerable patient cohort—the elderly. As an initial consequence, the Medical Retina Unit of Department of Ophthalmology (Clinic Landstraße, Vienna Healthcare Group, Austria) postponed appointments of patients with only one eye afflicted by wet AMD. This study examined the effect of a short-term treatment deferral caused by the first national COVID-19 lockdown in eyes of patients with ongoing therapy of wet AMD in Austria. The break led to a persistent visual loss despite re-treatment, which was still evident after 1 year. Our findings provide further support for an adequate and permanent therapy of wet AMD and regard intravitreal injections as urgent standard of care. It should be taken into consideration by authorities in future pandemic planning.

Abstract
Age-related macular degeneration (AMD) is one of the main causes of visual impairment and blindness in patients over 60 years in developed countries. Whilst no effective form of therapy is available for the dry form of AMD, intravitreal application of anti-VEGF substances is able to prevent the progression of neovascular AMD (nAMD) in most cases. Aside from the drugs ranibizumab, aflibercept and brolucizumab, other agents such as bevacizumab are often used off-label in order to save expense. The treatment intervals have also been refined, so as to reduce the burden on patients and health care systems. After fixed injection intervals, the pro re nata-regimen has been developed. Each month, it is decided whether the patient receives intravitreal injections based on fixed criteria. In the treat and extend-protocol, patients receive injections on each visit, but the intervals between injections vary due to the clinical outcomes. The observe-and-plan regime allows scheduling of the injection intervals in blocks, for three consecutive injections at a time. However, results of real-world studies were not able to reproduce those obtained in the pivotal studies. A high number of visits and fear of the injection procedure impose a burden on patients, that is mostly accepted due to fear of vision loss. Caregivers also complain of loss of productivity and income from having to provide regular support to patients. Health care systems worldwide are affected by increasing treatment numbers and the costs involved. The treatment of nAMD constitutes an achievement for modern medicine. However, despite the challenges, it must be evaluated and reviewed repeatedly in order to provide the best therapy for patients.

Abstract
Purpose To compare functional and anatomic outcome of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) treatments in neovascular age-related macular degeneration by using the treat and extend (TE) protocol. Methods In this retrospective chart study, treatment naïve 74 eyes of 74 age-related macular degeneration patients treated with IVR and IVA (38 eyes in IVR and 36 eyes in IVA group) with TE protocol were included. Following three consecutive monthly intravitreal injections, TE protocol was applied to each group. Patients were followed up for at least 36 months. Mean change in best-corrected visual acuity (BCVA), central macula thickness (CMT) and injection numbers over 3 years were compared. Results Among 36 months period, the mean number of injections was 17 ± 4 for both groups (p > 0.05). In terms of CMT, there was no statistically significant difference between groups at 36 months compared to baseline. A decrease of 72.55 ± 39.37 μm in CMT was detected in IVR group, whereas the decrease was 70.58 ± 33.96 μm in IVA group (p > 0.05). There was a significant increase in BCVA at 36 months of measurements. In addition, BCVA demonstrated an increase of 4.1 ± 0.44 letters in IVR group and 4.36 ± 0.67 letters in IVA group after 36 months compared to the baseline (p > 0.05). Conclusions Both IVR and IVA injections provided significant improvements and stability in BCVA and CMT, however there was no significant difference between IVR and IVA injections with TE protocol of 36 months.

Abstract
Purpose To report the one and two year outcome of cycles of three, monthly anti-VEGF injections given upon reactivation of the disease in eyes with neovascular age-related macular degeneration (nAMD). Methods Retrospective study of naïve nAMD cases with more than one year of follow-up, treated with a protocol of cycles of three monthly injections of anti-VEGF drugs upon reactivation. Visual acuity (VA) and central macular thickness (CMT) are the main outcome measures. Results Twenty-six patients with a mean age of 78.15 ± 9.29 years (57.7% female) were included. The mean follow-up was 30.89 ± 6.95 months. Treatment started with bevacizumab in all patients but in six patients was switched to aflibercept due to inadequate response to intravitreal bevacizumab injection. The mean VA at baseline and at 12 and 24 months was 53.87 ± 21.84, 60.54 ± 21.13, and 53.68 ± 27.16 ETDRS letters, respectively. Patients gained a mean of 6.67± 13.7 (p = 0.013, 95% CI= 0.60 to 12.65) and 0.77±15.21 (p = 0.4, 95% CI: –5.65 to 7.2) letters at 12 and 24 months. CMT at baseline, 12, and 24 months was 403.55 ± 147.59, 323.95 ± 79.58, and 298.59 ± 77.161 µm, respectively. The number of injections in the first and second years were 7.65 ± 2.64 and 5.52 ± 3.01, respectively. Three eyes (12.5%) lost >15 letters at 24 months. Conclusion This protocol can stabilize or improve vision in 87.5% of nAMD patients and can reduce the number of visits.

Abstract
PURPOSE To report the visual and anatomic outcomes in treatment-naïve neovascular age-related macular degeneration (nAMD) patients treated with aflibercept under a standardized Treat and Extend (T&E) protocol for up to 3 years of follow-up in "real-life" practice. METHODS This retrospective, observational, multicenter study included patients with treatment-naïve nAMD and at least 12 months of follow-up. T&E regimen adjustment was initiated after loading phase. At each visit best-corrected visual acuity (BCVA) and optical coherence tomography parameters were performed. RESULTS One hundred and thirty-six eyes of 115patients had at least 1 year of follow-up with 114 and 82 eyes completing at least 2 and 3 years of follow-up, respectively (mean follow-up duration: 2.7 ± 1.3 years). Mean age was 78.6 ± 8.6 years old and 52% were women. Mean BCVA increased from 60.6 ± 18.7 letters at diagnosis to 66.9 ± 16.2 letters at 1 year (+6.3 letters, p = 0.003) and remained stable throughout the follow-up period (63.1 ± 20.3 letters (+2.5, p = 0.1) and 64.0 ± 20.1 letters (+3.4, p = 0.27) at 2 and 3 years, respectively). The mean central retinal thickness decreased significantly from 358.2 ± 87.9 µm at baseline to 302 ± 71.7 µm at 12 months and maintained stable after 36 months of follow-up (297.1 ± 76 µm, p < 0.0001). Mean number of injections was 6.6 ± 2.2, 4.8 ± 1.9, and 5.6 ± 1.7 at 1, 2, and 3 years, respectively. Mean cumulative number of 16.4 ± 5.6 injections after 3 years. Mean treatment interval was 6.8 ± 2.5 weeks at 1 year. Eight-week and 12-week treatment interval were achieved in 59.5% and 19.1%, 65.8%, and 36.8% and 69.5% and 41.5% at 1, 2, and 3 years, respectively. CONCLUSIONS Our study demonstrated that intravitreal injections of aflibercept initiated under a standardized T&E for patients with treatment-naïve nAMD allow for significant visual improvement at 12 months, which was maintained over a 3-year follow-up period.

Abstract
PURPOSE To assess disease stability (absence of intra- and/or subretinal fluid) and the portion of eyes being capable to extend their treatment interval to ≥ 12 weeks in exudative age-related macular degeneration (AMD). METHODS A systematic literature search was performed in NCBI, PubMed, CENTRAL, and ClinicalTrials.gov to identify clinical studies reporting treatment outcomes for ranibizumab, aflibercept, and brolucizumab in exudative AMD under a treat-and-extend protocol and a follow-up of ≥ 12 months. Weighted mean differences and subgroup comparisons were used to integrate the different studies. RESULTS This meta-analysis refers to 29 published series, including 27 independent samples and 5629 patients. In the pooled group, disease stability was reported in 62.9% and 56.0%, respectively, after 12 and 24 months of treatment, whereas treatment intervals were extended to ≥ 12 weeks in 37.7% and 42.6%, respectively. Ranibizumab, aflibercept, and brolucizumab differed regarding their potential to achieve disease stability (56.3%, 64.5%, and 71.5% after 12, and 50.0%, 52.7% and 75.7% after 24 months; p = < 0.001) and to allow an interval extension to ≥ 12 weeks (28.6%, 34.2%, and 53.3% after 12, and 34.2%, 47.7%, and 41.7% after 24 months; p = < 0.001). CONCLUSION The portion of eyes achieving disease stability regressed in the second year, whereas the portion of eyes under a ≥ 12-week interval increased. This discrepancy may reflect the challenges in balancing between under-treatment and a reduced treatment burden.

Abstract
Objective: The purpose of our study was to determine the 4-year visual and anatomic outcomes of intravitreal aflibercept treatment for neovascular age-related macular degeneration (AMD) using a treat-and-extend (TAE) regimen. Methods: We retrospectively reviewed the medical records of 39 patients with neovascular AMD who were treated continuously with intravitreal aflibercept injections using the TAE regimen for at least 4 years. The outcome measures were the best-corrected visual acuity (BCVA) and central macular thickness (CMT) on spectral-domain optical coherence tomography. The BCVAs were measured as decimal values and converted to the corresponding Early Treatment Diabetic Retinopathy Study (ETDRS) letter scores for statistical analysis. The Wilcoxon signed-rank test was used to compare the differences in BCVAs and CMTs. Results: The mean ETDRS letter scores improved significantly from 63.9 at baseline to 70.4, 67.8, 67.2, and 67.3 at 1, 2, 3, and 4 years, respectively. The mean baseline CMT was 380 µm, which decreased significantly to 229, 231, 221, and 210 µm at 1, 2, 3, and 4 years, respectively. The mean numbers of injections were 7.9, 6.0, 5.5, and 5.4 at 1, 2, 3, and 4 years, respectively. The percentages of patients with a treatment interval of 12 weeks or more were 46.2%, 46.2%, 43.6%, and 46.2% at 1, 2, 3, and 4 years, respectively. At year 4, 30.8% of the patients had a treatment interval of 7 weeks or less, whereas 25.6% had 16 weeks or more. Conclusion: Intravitreal aflibercept TAE treatment may be an effective and efficient method for treating patients with neovascular AMD up to 4 years of follow-up. The TAE regimen is a potential tool to optimize appropriate treatment intervals, avoiding both undertreatment and overtreatment of neovascular AMD.

Insights From Survival Analyses During 12 Years of Anti-Vascular Endothelial Growth Factor Therapy for Neovascular Age-Related Macular Degeneration. JAMA Ophthalmol 2021; 139:57-67. [PMID: 33211064 PMCID: PMC7677877 DOI: 10.1001/jamaophthalmol.2020.5044] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Accepted: 10/05/2020] [Indexed: 01/01/2023]
Abstract
Importance Although multiple imputation models for missing data and the use of mixed-effects models generally provide better outcome estimates than using only observed data or last observation carried forward in clinical trials, such approaches usually cannot be applied to visual outcomes from retrospective analyses of clinical practice settings, also called real-world outcomes. Objective To explore the potential usefulness of survival analysis techniques for retrospective clinical practice visual outcomes. Design, Setting, and Participants This retrospective cohort study covered a 12-year observation period at a tertiary eye center. Of 10 744 eyes with neovascular age-related macular degeneration receiving anti-vascular endothelial growth factor (VEGF) therapy between October 28, 2008, and February 1, 2020, 7802 eyes met study criteria (treatment-naive, first-treated eyes starting anti-VEGF therapy). Eyes were excluded from the analysis if they received photodynamic therapy or macular laser, any previous anti-VEGF therapy, treatment with anti-VEGF agents other than ranibizumab or aflibercept, or had an unknown date or visual acuity (VA) value at first injection. Main Outcomes and Measures Kaplan-Meier estimates and Cox proportional hazards modeling were used to consider VA reaching an Early Treatment Diabetic Retinopathy Study (ETDRS) letter score of 70 (Snellen equivalent, 20/40) or better, duration of VA sustained at or better than 70 (20/40), and VA declining to 35 (20/200) or worse. Results A total of 7802 patients (mean [SD] age, 78.7 [8.8] years; 4776 women [61.2%]; and 4785 White [61.3%]) were included in the study. The median time to attaining a VA letter score greater than or equal to 70 (20/40) was 2.0 years (95% CI, 1.87-2.32) after the first anti-VEGF injection. Predictive features were baseline VA (hazard ratio [HR], 1.43 per 5 ETDRS letter score or 1 line; 95% CI, 1.40-1.46), baseline age (HR, 0.88 per 5 years; 95% CI, 0.86-0.90), and injection number (HR, 1.12; 95% CI, 1.10-1.15). Of the 4439 of 7802 patients (57%) attaining this outcome, median time sustained at an ETDRS letter score of 70 (20/40) or better was 1.1 years (95% CI, 1.1-1.2). Conclusions and Relevance In this cohort study, patients with neovascular age-related macular degeneration beginning anti-VEGF therapy were more likely to experience positive visual outcomes within the first 2.0 years after treatment, typically maintaining this outcome for 1.1 years but then deteriorating to poor vision within 8.7 years. These findings demonstrate the potential usefulness of the proposed analyses. This data set, combined with the statistical approach for retrospective analyses, may provide long-term prognostic information for patients newly diagnosed with this condition.

Abstract
PURPOSE To describe the first 13 years of anti-vascular endothelial growth factor (anti-VEGF) therapy from the perspective of a public ophthalmic department serving a local community of almost one million people. METHODS Retrospective registry study. Data from Oslo University Hospital, Norway were collected from 2006 through 2018. Hospital episode statistics were searched for episodes of care encompassing intravitreal anti-VEGF procedures. Patient-specific ID numbers, diagnoses, and drug codes were registered. In general, bevacizumab was used as first-line treatment, with aflibercept reserved for resistant cases from 2013. RESULTS The number of unique patients treated per year increased from 130 in 2006 to 3428 in 2018. In 2018, 2488 (73%) patients had also received treatment the previous year. The number of yearly injections increased from 228 in 2006 to 25 570 in 2018. In 2018 the diagnosis macular degeneration constituted 69% of injections, diabetic retinopathy constituted 15%, retinal vein occlusion constituted 13%, and other diagnoses constituted 3%. In the same year 49% of injections were with bevacizumab, 46% with aflibercept, 4% with ranibizumab, and 1% with dexamethasone implants. The bevacizumab to aflibercept ratio was almost 1:1 for macular degeneration and diabetic retinopathy; for retinal vein occlusion the ratio was 13:7. CONCLUSION In 13 years there was an approximately 100-fold increase in the number of yearly intravitreal injections. A majority of patients received long-term treatment. Macular degeneration was the most common diagnosis. Using bevacizumab as first-line treatment, with aflibercept reserved for resistant cases from 2013, eventually resulted in a nearly 1:1 ratio in drug usage.

Abstract
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.

Abstract
Age-related macular disease (AMD) is a major cause of blindness and there is little treatment currently available by which the progress of the basic disorder can be modulated. Histological and clinical studies show that the major tissues involved are the outer retina, retinal pigment epithelium, Bruch's membrane and choroid. Because of a wide variation of phenotype from one case to another, it has been suggested that accurate phenotyping would be necessary for assessment of the effectiveness of treatment that is tissue-directed. However, based on findings from the study of human donor material and animal models of disease and of cell culture, it is concluded that retinal pigment epithelial dysfunction plays a central role in the disease process in most, if not all, cases of early AMD. The metabolism of phagosomal material, particularly lipids, and energy generation are interdependent, and dysfunction of both appears to be important in the genesis of disease. Evidence exists to suggest that both can be modulated therapeutically. These metabolic functions are amenable to further investigation in both the normal state and in disease. Once fully characterised, it is likely that treatment could be directed towards a limited number of functions in single tissue, thus simplifying treatment strategies.

Abstract
PURPOSE To describe visual outcomes, frequency of treatment and monitoring visits, and anti-vascular endothelial growth factor drugs used in usual care in participants who exited a trial in which treatment for neovascular age-related macular degeneration (nAMD) was initiated with bevacizumab or ranibizumab. DESIGN Multicenter cohort study up to 7 years after trial exit. PARTICIPANTS Patients enrolled in the Inhibition of VEGF in Age-related choroidal Neovascularisation (IVAN) trial; after excluding participants from 2 sites and who died or withdrew during the trial, 537 were included in this follow-up cohort. METHODS Data were collected between May 26, 2016, and August 24, 2017. Distance visual acuity (DVA) (letters read) in both eyes and treatments for nAMD administered to either eye at all usual care visits were extracted from medical records of all participants until the point of data collection (duration of study eye monitoring). MAIN OUTCOME MEASURES Rate of change of DVA during active surveillance of the study eye (study eye monitoring), estimated using a multivariable linear random effects model. Other outcome measures were visit and treatment frequency and switches in anti-vascular endothelial growth factor (VEGF) drug. RESULTS Data were obtained for 99% (532/537) of eligible participants. The median duration of study eye monitoring after IVAN exit was 3.3 years (interquartile range [IQR], 1.3-4.7), and median DVA was 58.0 letters (IQR, 34.0-73.0). Study eye DVA deteriorated by 4.3 (95% confidence interval [CI], 3.7-4.9) letters per year. Injection rate did not influence the rate of change in DVA after adjusting for key covariates. After IVAN exit, 174 participants (32%) received no treatment; 332 of 358 (93%) were treated first with ranibizumab, 78 (23%) of whom switched to aflibercept. The DVA was similar among participants who switched or did not switch at the end of study monitoring. CONCLUSIONS Approximately 5 years after the IVAN study finished, with unprecedented completeness of follow-up for such a trial, the trajectory of functional decline in the study eye was shown to be greater than that previously reported for incomplete trial cohorts. Anti-VEGF injection rates and treatment switches were not important factors in determining visual acuity outcomes.

Abstract
PURPOSE To correlate the rate of intravitreal anti-VEGF injections and the use of aflibercept as a second-line treatment with visual impairment throughout Finland. METHODS Information related to anti-VEGF treatment, proportions of bevacizumab and aflibercept and new visual impairments due to wet age-related macular degeneration (AMD) was gathered from 5 university hospitals and 14 central hospital districts between 2015 and 2017 covering 232 568 injections and 1172 visual impairments. RESULTS Between 2015 and 2017, the number of annual total anti-VEGF injections increased from 60 412 to 93 589 (+24.5% annual change) and of aflibercept injections from 8299 to 20 833 (+58.7% annual change). The 3-year average for total anti-VEGF injections ranged from 9.6 to 21.1 (median 13.3) per 1000 citizens between hospital districts and for aflibercept injections from 0.8 to 4.0 (median 1.9). According to the primary protocol for wet AMD, during 2015-2017, the number of total anti-VEGF injections increased from 10.9 to 15.2 per 1000 citizens with the pro re nata (PRN) protocol and from 11.3 to 18.9 with the treat-and-extend regimen (TER). The 3-year average of aflibercept injections as a second-line treatment, but not the total number of anti-VEGF or bevacizumab injections, inversely correlated with new onset visual impairments (R = -0.505, P = 0.027) in the hospital districts. The number of visual impairments did not differ between the hospital districts according to the PRN and TER protocols (1.23 ± 0.41 and 1.14 ± 0.67, respectively, per 1000 citizens aged ≥64 years, P = 0.713). CONCLUSION These results emphasize that the use of aflibercept injections as a second-line treatment may decrease new onset visual impairments.

Long-Term Visual Outcomes for a Treat-and-Extend Antivascular Endothelial Growth Factor Regimen in Eyes with Neovascular Age-Related Macular Degeneration: Up to Seven-Year Follow-Up. J Ophthalmol 2020; 2020:3207614. [PMID: 32802487 PMCID: PMC7415083 DOI: 10.1155/2020/3207614] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Revised: 03/23/2020] [Accepted: 04/23/2020] [Indexed: 11/18/2022] Open
Abstract
Purpose To report long-term visual and anatomical outcomes in eyes with neovascular age-related macular degeneration (nAMD) treated with a treat-and-extend regimen (TER) of intravitreal antivascular endothelial growth factor (anti-VEGF) injections in real-world settings. Methods Retrospective cohort study of consecutive patients with nAMD treated with a TER of anti-VEGF intravitreal injections by a single retina specialist (GC). Patients with nAMD who had at least one year of follow-up were identified using an electronic database. Best-corrected visual acuity (BCVA), comprehensive ophthalmologic examination, and macular OCT were performed at each visit. Patients received a loading dose of three monthly intravitreal injections and then were treated according to a TER of bevacizumab, ranibizumab, and/or aflibercept. The number of injections, BCVA, and central retinal thickness (CRT) were evaluated during the follow-up period. Results 180 eyes from 180 patients were included in the study. Mean age was 75 ± 9 (range: 51–96). Mean BCVA was 0.77 ± 0.64 LogMAR at baseline, 0.69 ± 0.58 LogMAR (p = 0.0057) after loading phase, 0.64 ± 0.55 LogMAR (p = 0.0001) after 6 months of TER, and 0.76 ± 0.71 LogMAR after 6 years of treatment (n = 32 at year 6). CRT decreased significantly after the loading phase (p = 0.0002). The mean number of intravitreal injections per year was 7.6 during the first three years of treatment and then decreased to 5.9 during year 4 to 7. Conclusions This retrospective study of 180 nAMD patients treated with a TER of intravitreal anti-VEGF demonstrates an initial improvement of BCVA after loading phase, followed by long-term visual stabilization for at least six years. These results were obtained with a high number of injections, averaging close to six injections per year during long-term follow-up. In light of the natural evolution of nAMD, these data support the long-term efficacy of this treatment under real-world conditions of heterogeneity of patients and type of anti-VEGF used.

Abstract
Background To evaluate the three-year outcome after intravitreal aflibercept injection (IAI) for neovascular age-related macular degeneration (nAMD). Methods Forty-nine treatment-naïve nAMD patients (50 eyes) were enrolled in this prospective study. The eyes received IAI at two-month intervals in the first year. The treatment regimen was changed to IAI based on a treat-and-extend approach in the second and third years. Results Twenty-nine eyes of 28 patients were successfully followed up over 36 months. The nAMD subtypes included 15 eyes with typical AMD and 14 eyes with polypoidal choroidal vasculopathy. The number of IAIs performed over the 3 years was 17.2 ± 3.1 (mean ± standard deviation). The mean logMAR, which was 0.42 at baseline, improved to 0.19 (P = 0.001) at 12 months, and 0.26 (P = 0.049) at 36 months. The central retinal thickness (CRT) was 329 ± 120 μm at baseline, 151 ± 38 μm (P < 0.001) at 12 months, and 143 ± 61 μm (P < 0.001) at 36 months. The mean subfoveal choroidal thickness (SFCT) was 288 ± 97 μm at baseline, 243 ± 82 μm (P < 0.001) at 12 months, and 208 ± 63 μm (P < 0.01) at 36 months. The changes in logMAR, CRT, and SFCT over the study period did not differ between typical AMD and PCV. Conclusion Long-term aflibercept injection can achieve visual improvement and reduce the thickness of the retina and choroid in nAMD. Morphological improvement of these tissues may not be sufficient to sustain earlier visual improvement over the long-term.

Abstract
Wet age-related macular degeneration is a chronic condition culminating, in most cases, in blindness. The introduction of anti-angiogenic agents in 2006 has represented a major breakthrough in the treatment of the disease, but timely and effective treatment with regular follow-up and monitoring is mandatory to stabilize and preserve visual acuity. In clinical practice, however, appropriate therapy provision is frequently challenged by economic and organizational issues that result in suboptimal visual outcomes and increased incidence of legal blindness. International Guidelines have defined a diagnostic and therapeutic pathway to ensure the best practice in wet age-related macular degeneration management, but reference parameters to evaluate and compare the performance of Retina Centers are lacking. To address the appropriateness of wet age-related macular degeneration management in Italy, a multidisciplinary panel of ten experts gathered in three meetings. They defined three sets of indicators and relative benchmark values that each Center should comply with to ensure patients optimal care already from the first access: (a) clinical intervention indicators, to determine the possible Center’s deviation from the diagnostic and therapeutic pathway; (b) outcome indicator, to evaluate the socioeconomic impact of the healthcare systems’ performance; (c) management indicators, to test the size of the gap between the Center’s supply and demand. Once the indicators have been analyzed, healthcare systems can plan actions to improve appropriateness and monitor their effects. However, to put this in practice, a concerted effort by all parts involved in healthcare provision is required, together with adequate systems to analyze clinical and administrative documentation.

Abstract
PURPOSE Evaluate and compare the visual and morphological results of Pro re nata (PRN) and treat-and-extend (T&E) treatment regimens at 3 years in real world clinical practice. METHODS Retrospective study of patients with neovascular age macular degeneration (AMD) treated with anti-VEGF with 3 years of continuous follow-up and no previous anti-VEGF treatment. Best corrected visual acuity (BCVA), central foveal thickness (CFT) and number of intravitreal injections outcomes were tested for statistical differences between the two groups at baseline and during follow-up. RESULTS A total of 240 eyes were included in the study, 170 in the PRN group and 70 in the T&E group. At 12 months, mean BCVA (ETDRS letters) gain from baseline was at its highest point in the T&E group (+6.38±13.32; p=0.25). In the PRN group, BCVA peaked at 3 months and slowly decreased until end of follow-up. With both regimens, from baseline, CFT continued to decrease until the second year (PRN -138.81 [-846.7 to +162.77] and T&E -81 [-604 to +100] μm, p=0.06). After that, T&E group maintained this tendency, reaching the lowest CFT value at 36 months, whereas PRN group showed an increased in CFT values (PRN -104 [-807.7 to +297] μm and T&E -103 [-575 to +244], μm p=0.63). Patients treated with T&E regimen received a significantly higher number of injections (PRN 16.3±7.6 vs T&E 23.9 ±9.4, p<0.01). CONCLUSION Our results demonstrated a trend towards for T&E to achieve higher marks in BCVA, peaking at 12 months, and lower CFT thickness at the end of three years. Despite the higher number of injections performed in the T&E group the mean BCVA reverts to baseline values at 3 years.

Abstract
PURPOSE To determine the long-term visual outcomes and intravitreal injection burden of patients with exudative age-related macular degeneration (AMD) treated with intravitreal anti-vascular endothelial growth factor (VEGF) injections. DESIGN Retrospective cohort study. PARTICIPANTS Patients with exudative AMD treated with intravitreal anti-VEGF injections with annual office visits for at least 7 years. METHODS Snellen visual acuity was measured at baseline and then annually until the last year of follow-up. The number of injections was recorded on an annual basis during each year of follow-up. MAIN OUTCOME MEASURES The change in the frequency of injections over time along with the change in visual acuity each year from the baseline visit through 7 years. RESULTS During this period, 533 eyes of 429 patients were treated for exudative AMD. Of these, 391 eyes (73%) met the inclusion criteria of annual office visits and received a mean of 5.8 ± 2.5 intravitreal injections per year. The baseline mean visual acuity was 0.6 ± 0.5 logarithm of the minimum angle of resolution (logMAR; Snellen equivalent, 20/80), and the 7-year visual acuity was 0.8 ± 0.6 logMAR (Snellen equivalent, 20/126; P < 0.0001). When compared with the 142 eyes that did not undergo an office visit for a continuous 12-month period, eyes with annual office visits showed similar baseline mean visual acuity (0.7 logMAR vs. 0.6 logMAR; P = 0.2102), but more injections per year (P < 0.0001). Of the 533 total eyes, 124 eyes (23%) maintained better than 20/40 visual acuity at 7 years. These eyes received more injections overall per year (6.5 vs. 5.5 injections per year; P = 0.0007). CONCLUSIONS In a real-world setting, eyes that maintained consistent, long-term follow-up received significantly more intravitreal injections per year than eyes with inconsistent follow-up. Eyes with 20/40 or better vision at study conclusion received more injections per year than eyes with worse than 20/40 vision.

Impact of Sub-Retinal Fluid on the Long-Term Incidence of Macular Atrophy in Neovascular Age-related Macular Degeneration under Treat & Extend Anti-Vascular Endothelial Growth Factor Inhibitors. Sci Rep 2020; 10:8036. [PMID: 32415240 PMCID: PMC7229002 DOI: 10.1038/s41598-020-64901-9] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Accepted: 04/20/2020] [Indexed: 11/29/2022] Open
Abstract
Sub-retinal fluid (SRF) has been discussed as a protective factor against macular atrophy in eyes with neovascular age-related macular degeneration (nAMD).To gauge the impact of SRF on macular atrophy, a database of 310 nAMD eyes was screened for eyes manifesting an SRF-only phenotype under treat & extend anti-VEGF treatment, defined as nAMD expressing CNV exudation beyond the three monthly anti-VEGF loading doses by SRF only without any signs of exudative intra-retinal fluid (IRF) for ≥3 years. Incidence of macular atrophy and treatment responses were evaluated on multimodal imaging, including optical coherence tomography (OCT), blue autofluorescence (BAF) and near-infrared (NIR) confocal scanning laser ophthalmoscopy and fluorescence and indocyanine green angiography (FAG/ICGA). In total, 27 eyes (8.7%) of 26 patients with a mean follow-up of 4.2 ± 0.9 (3–5) years met the inclusion criteria. Mean age was 72 ± 6 (range: 61–86) years. The SRF only phenotype was seen from baseline in 14 eyes (52%), and in 13 eyes (48%) after a mean 1.0 ± 1.3 (1–3) injections. In years 1 to 5, mean 7.5, 5.9, 6.1, 6.1 and 7.0 anti-VEGF injections were given (p = 0.33). Cumulative macular atrophy incidence was 11.5% at year 1, 15.4% throughout years 2 to 4, and 22.4% at year 5. In conclusion, eyes manifesting activity by SRF only in treat & extend anti-VEGF regimen for nAMD seem to exhibit rather low rates of macular atrophy during long-term follow-up. SRF might be an indicator of a more benign form of nAMD.

Abstract
BACKGROUND Age-related macular degeneration (AMD) is one of the leading causes of permanent blindness worldwide. The current mainstay of treatment for neovascular AMD (nAMD) is intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents: aflibercept, ranibizumab, and off-label bevacizumab. Injections can be given monthly, every two or three months ('extended-fixed'), or as needed (pro re nata (PRN)). A variant of PRN is 'treat-and-extend' whereby injections are resumed if recurrence is detected and then delivered with increasing intervals. Currently, injection frequency varies among practitioners, which underscores the need to characterize an optimized approach to nAMD management. OBJECTIVES To investigate the effects of monthly versus non-monthly intravitreous injection of an anti-VEGF agent in people with newly diagnosed nAMD. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, LILACS, and three trials registers from 2004 to October 2019; checked references; handsearched conference abstracts; and contacted pharmaceutical companies to identify additional studies. SELECTION CRITERIA We included randomized controlled trials (RCTs) that compared different treatment regimens for anti-VEGF agents in people with newly diagnosed nAMD. We considered standard doses only (ranibizumab 0.5 mg, bevacizumab 1.25 mg, aflibercept 2.0 mg, or a combination of these). DATA COLLECTION AND ANALYSIS We used standard Cochrane methods for trial selection, data extraction, and analysis. MAIN RESULTS We included 15 RCTs. The total number of participants was 7732, ranging from 37 to 2457 in each trial. The trials were conducted worldwide. Of these, six trials exclusively took place in the US, and three included centers from more than one country. Eight trials were at high risk of bias for at least one domain and all trials had at least one domain at unclear risk of bias. Seven trials (3525 participants) compared a PRN regimen with a monthly injection regimen, of which five trials delivered four to eight injections using standard PRN and three delivered nine or 10 injections using a treat-and-extend regimen in the first year. The overall mean change in best-corrected visual acuity (BCVA) at one year was +8.8 letters in the monthly injection group. Compared to the monthly injection, there was moderate-certainty evidence that the mean difference (MD) in BCVA change at one year for the standard PRN subgroup was -1.7 letters (95% confidence interval (CI) -2.8 to -0.6; 4 trials, 2299 participants), favoring monthly injections. There was low-certainty evidence of a similar BCVA change with the treat-and-extend subgroup (0.5 letters, 95% CI -3.1 to 4.2; 3 trials, 1226 participants). Compared to monthly injection, there was low-certainty evidence that fewer participants gained 15 or more lines of vision with standard PRN treatment at one year (risk ratio (RR) 0.87, 95% CI 0.76 to 0.99; 4 trials, 2299 participants) and low-certainty evidence of a similar gain with treat-and-extend versus monthly regimens (RR 1.11, 95% CI 0.91 to 1.36; 3 trials, 1169 participants). The mean change in central retinal thickness was a decrease of -166 μm in the monthly injection group; the MD compared with standard PRN was 21 μm (95% CI 6 to 32; 4 trials, 2215 participants; moderate-certainty evidence) and with treat-and extend was 22 μm (95% CI 37 to -81 μm; 2 trials, 635 participants; low-certainty evidence), in favor of monthly injection. Only one trial (498 participants) measured quality of life and reported no evidence of a difference between regimens, but data could not be extracted (low-certainty evidence). Both PRN regimens (standard and 'treat-and-extend') used fewer injections than monthly regimens (standard PRN: MD -4.6 injections, 95% CI -5.4 to -3.8; 4 trials, 2336 participants; treat-and-extend: -2.4 injections, 95% CI -2.7 to -2.1 injections; moderate-certainty evidence for both comparisons). Two trials provided cost data (1105 participants, trials conducted in the US and the UK). They found that cost differences between regimens were reduced if bevacizumab rather than aflibercept or ranibizumab were used, since bevacizumab was less costly (low-certainty evidence). PRN regimens were associated with a reduced risk of endophthalmitis compared with monthly injections (Peto odds ratio (OR) 0.13, 95% CI 0.04 to 0.46; 6 RCTs, 3175 participants; moderate-certainty evidence). Using data from all trials included in this review, we estimated the risk of endophthalmitis with monthly injections to be 8 in every 1000 people per year. The corresponding risk for people receiving PRN regimens was 1 in every 1000 people per year (95% CI 0 to 4). Three trials (1439 participants) compared an extended-fixed regimen (number of injections reported in only one large trial: 7.5 in one year) with monthly injections. There was moderate-certainty evidence that BCVA at one year was similar for extended-fixed and monthly injections (MD in BCVA change compared to extended-fixed group: -1.3 letters, 95% CI -3.9 to 1.3; RR of gaining 15 letters or more: 0.94, 95% CI 0.80 to 1.10). The change in central retinal thickness was a decrease of 137 μm in the monthly group; the MD with the extended-fixed group was 8 μm (95% CI -11 to 27; low-certainty evidence). The frequency of endophthalmitis was lower in the extended-fixed regimen compared to the monthly group, but this estimate was imprecise (RR 0.19, 95% CI 0.03 to 1.11; low-certainty evidence). If we assumed a risk of 8 cases of endophthalmitis in 1000 people receiving monthly injections over one year, then the corresponding risk with extended-fixed regimen was 2 in 1000 people (95% CI 0 to 9). Other evidence comparing different extended-fixed or PRN regimens yielded inconclusive results. AUTHORS' CONCLUSIONS We found that, at one year, monthly regimens are probably more effective than PRN regimens using seven or eight injections in the first year, but the difference is small and clinically insignificant. Endophthalmitis is probably more common with monthly injections and differences in costs between regimens are higher if aflibercept or ranibizumab are used compared to bevacizumab. This evidence only applies to settings in which regimens are implemented as described in the trials, whereas undertreatment is likely to be common in real-world settings. There are no data from RCTs on long-term effects of different treatment regimens.

Abstract
PURPOSE To optimize the aflibercept treat-and-extend protocol in wet age-related macular degeneration (wAMD). METHODS A prospective randomized clinical trial consisting of 52 eyes from 52 patients with treatment-naïve wAMD. Patients received three monthly aflibercept injections and were then randomized 1:1 to two different dosing protocols. In treat-and-extend protocol with moderate extensions (T&Em), after the loading phase the treatment interval was extended 1 week at a time up to 12 weeks and then by 2 weeks up to 16 weeks. In treat-and-extend protocol with rapid extensions (T&Er), the interval was first extended to 8 weeks and then by 2 weeks at a time up to 16 weeks. Main outcome measure was the number of given aflibercept injections. RESULTS Fifty (96%) patients completed the 1-year follow-up. Patient and ophthalmic baseline variables were comparable between the study groups. At 1 year, central subfield macular thickness reduced by 194.3 ± 153.6 μm in T&Em protocol, compared with 194.2 ± 176.6 μm in T&Er (p = 0.997). Eyes with T&Em gained 10.3 ± 11.5 letters from baseline and eyes with T&Er 11.4 ± 10.6 letters (p = 0.434), and dry macula was observed in 72% of eyes with T&Em compared to 68% with T&Er (p = 0.758). At 1 year, the treatment interval was 8.5 ± 2.2 weeks in T&Em and 10.3 ± 2.8 weeks in T&Er (p = 0.017), and the total number of injections 8.64 ± 1.58 and 6.96 ± 0.79, respectively (p < 0.001). In the rapid extensions protocol, 48% of eyes reached a 12-week treatment interval or beyond at 1 year. CONCLUSIONS At one year, the anatomical and functional responses were comparable between the moderate and rapid extensions protocols, with fewer aflibercept injections in the rapid extension protocol.

Abstract
PURPOSE To report 10-year, real-world experiences with intravitreal therapy (IVT) using vascular endothelial growth factor inhibitors for neovascular age-related macular degeneration (nAMD). METHODS Retrospective single-centre review of IVT-log 2007-2019 with a treatment-as-needed regimen and ETDRS visual acuity charts. RESULTS The 4,678 treatment-naïve eyes of 3,668 patients received a mean of 5.4 IVT in the first year and 4.0-4.3 IVT yearly thereafter. Baseline mean best corrected visual acuity (BCVA) was 57.9 (±16.4) letters (6/18) that improved a mean +2.1 (±0.2) letters at the first follow-up visit and gradually declined to -5.0 (±2.2) letters after 10 years. At baseline, there were 29% with BCVA ≥6/12. This proportion increased to 31-37% until year 9. There were 8% with BCVA loss of ≥3 lines at the first follow-up visit increasing to 34% after 10 years. Poorer baseline BCVA was associated with larger increase in BCVA (p < 0.0001, multiple linear regression). The 2,566 (55%) discontinued eyes had a mean baseline BCVA of 56.9 (±16.4) letters compared with 61.5 (±15.9) letters for eyes remaining in treatment. In year 0-7, the discontinued eyes lost an additional mean 2-4 letters (last observation carried forward) but were similar thereafter. There were 12.6% (74 of 585 eligible eyes) that were still in treatment after 10 years. At baseline, 10% had bilateral nAMD. Of patients with unilateral presentation, 17% had received fellow-eye IVT after 5 years. CONCLUSION A treatment-as-needed regimen stabilized BCVA in active nAMD up to 10 years in most eyes. Baseline BCVA was the most important prognostic factor.

Seven-Year Visual and Anatomical Outcomes of Intravitreal Vascular Endothelial Growth Factor Inhibition for Neovascular Age-Related Macular Degeneration. J Ophthalmol 2020; 2020:8345850. [PMID: 32211201 PMCID: PMC7042519 DOI: 10.1155/2020/8345850] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 11/07/2019] [Accepted: 12/26/2019] [Indexed: 11/23/2022] Open
Abstract
Purpose To evaluate 7-year visual and anatomical outcomes of intravitreal injections (IVI) with antivascular endothelial growth factor (anti-VEGF) for neovascular age-related macular degeneration (nAMD) based on a personalized pro re nata (PRN) regimen. Methods Anonymized data of 124 consecutive eyes in 121 patients with treatment-naïve nAMD were initially collected in 2010. Of those, 45 received anti-VEGF IVI at least every 6months until 2017 in one single center in Austria and hence were retrospectively analyzed. All eyes had been initiated on a loading dose of 3 monthly IVI with different anti-VEGF agents followed by a PRN regimen in the first year. At year 2, monitoring as well as therapeutic intervention could be prolonged every 2weeks up to intervals of 3months without capping treatment. Primary outcome measure was the change of visual acuity (VA) assessed by Early Treatment Diabetic Retinopathy Study charts at 4 meters (ETDRS) in letters—counting every correctly read letter—and converted to Snellen. Secondary outcome measures were number of injections and change of central retinal thickness (CMT) from baseline. Results Mean baseline VA was 20/63 + 1 (0.63 ± 0.26 ETDRS) and declined to 20/100 + 2 (0.45 ± 0.33) with an overall loss of 9 letters ETDRS after 7years (p = 0.001). An average of 3.5 ± 1.9 IVI was given per year and eye. Mean CMT at baseline was 322 ± 95 μm, decreased by 52 μm, decreased by 52 μm, decreased by 52 μm, decreased by 52 μm to 270 ± 70 μm within the first year, and remained below baseline at year 7 (271 ± 106 μm; p = 0.001). An average of 3.5 ± 1.9 IVI was given per year and eye. Mean CMT at baseline was 322 ± 95 μm, decreased by 52 μm to 270 ± 70 μm within the first year, and remained below baseline at year 7 (271 ± 106 μm; p < 0.001). Conclusions Our data confirm an absolute vision loss in eyes compromised by nAMD after 7 years of continuous VEGF inhibition. The visual decline was significantly related to baseline VA as well as the number of injections. We suggest following patients thoroughly independent of the initial VA and a greater incentive for the physician to treat.

BMJ Open Ophthalmol 2019; 4:e000353. [PMID: 31673632 PMCID: PMC6797267 DOI: 10.1136/bmjophth-2019-000353] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Revised: 09/03/2019] [Accepted: 09/14/2019] [Indexed: 11/04/2022] Open
Abstract
Objective To prospectively explore the following patient-reported outcome measures (PROMs) in the management of neovascular age-related macular degeneration (nAMD): (1) self-reported visual function, (2) symptom-state, (3) general-health and (4) satisfaction of treatment. Methods and analysis Corresponding to the four PROMs, participants responded to the following questionnaires: (1) National Eye Institute Visual-Functioning-Questionnaire (NEI-VFQ-25), (2) Patient-Acceptable-Symptom-Status (PASS 5), (3) EuroQol-Group-Questionnaire (EQ-5D-3L) and (4) Dimensions of Importance in Treatment of nAMD (DITAMD). Data were collected at baseline and after 3, 6 and 12 months of intravitreal antivascular endothelial growth factor treatment. Results were evaluated with t-tests and mixed linear regression analyses. Results The study included 197 patients. At baseline NEI-VFQ-25 (79.53±14.52) and EQ-5D (0.74±0.28) had relatively high scores, whereas PASS 5 was below 'acceptable' (3.30±0.80). At 12 months NEI-VFQ-25 and PASS 5 showed significant improvement, whereas EQ-5D and DITAMD remained unchanged. At baseline patients receiving treatment of the better-seeing eye (BSE) (n=52) reported significantly worse NEI-VFQ-25 and PASS 5 than patients for whom treatment only involved the worse-seeing eye (WSE), (n=145). In contrast to BSE patients, there was no improvement of NEI-VFQ-25 for WSE patients at 12 months, despite a significant improvement in best-corrected visual acuity (BCVA). Two independent variables, treatment including the BSE and BCVA for the treated eye, were found to predict both NEI-VFQ-25 and PASS 5. Conclusion After 12 months of nAMD treatment, there was a significant improvement in PASS 5 and NEI-VFQ-25, the latter depending on whether therapy included BSE. EQ-5D and DITAMD remained unaltered.

Clin Ophthalmol 2019; 13:1981-1989. [PMID: 31631966 PMCID: PMC6790115 DOI: 10.2147/opth.s224319] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Accepted: 09/10/2019] [Indexed: 11/23/2022] Open
Abstract
Purpose To report the results of 9-year follow-up examinations and predictive factors for visual acuity outcome after intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents to treat retinal angiomatous proliferation (RAP). Methods We conducted a retrospective observational study of 85 treatment-naïve eyes in 61 patients (21 men, 40 women; age range, 70-95 years; mean age, 84.0 years) treated with intravitreal injections of anti-VEGF agents. All patients received three consecutive monthly injections as an induction treatment. During the maintenance phase, the patients received intravitreal injections as needed or fixed dosing. The primary outcome measures were best-corrected visual acuity (BCVA) during the follow-up period. Furthermore, we investigated potential predictive factors of improvement in visual acuity. The proportion of patients who developed specific complications were also analyzed. Results The mean BCVA gradually decreased from 0.58 at baseline to 0.70 at 36 months (P = 0.146), 0.82 at 48 months (P = 0.004), and 0.92 at 108 months (P = 0.021). Improvement in visual acuity at the final visits was associated with baseline visual acuity and central foveal thickness. Massive subretinal hemorrhage, fibrotic scars, and macular atrophy developed in 4 (4.7%), 9 (10.6%), and 50 (56.8%) eyes, respectively, at the final visits, and were all significantly associated with final visual acuity (P = 0.013, P < 0.001, and P = 0.001, respectively). Conclusion Long-term stabilization of vision in patients with RAP, regardless of treatment modality, was difficult to achieve by using intravitreal injections of anti-VEGF agents. Earlier detection and treatment are important to maintain visual acuity in patients with RAP.
