Kim JG, Kim YC, Kang KT. Two-Year Follow-Up Study of Patients with Neovascular Age-Related Macular Degeneration Undergoing Anti-VEGF Treatment during the COVID-19 Pandemic. J Clin Med 2024; 13:867. [PMID: 38337561 PMCID: PMC10856664 DOI: 10.3390/jcm13030867] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 01/24/2024] [Accepted: 01/27/2024] [Indexed: 02/12/2024] Open
Abstract
BACKGROUND regular intravitreal anti-vascular endothelial growth factor (VEGF) treatment is crucial for patients with neovascular age-related macular degeneration (nAMD), and delayed treatment can exacerbate disease progression. METHODS we compared the outcomes of on-time versus delayed intravitreal anti-VEGF treatment for patients with nAMD. This study was conducted during the coronavirus disease 2019 (COVID-19) pandemic with a 2-year follow-up period. The best-corrected visual acuity (BCVA) and anatomical findings were evaluated before the pandemic, during the pandemic, and at 6-, 12-, 18-, and 24-months post-pandemic. RESULTS The delayed and on-time groups comprised 54 and 72 patients, respectively. After the pandemic, the injection interval increased by 0.65 ± 1.51 months (p = 0.003), with 22.2% of the patients in the delayed group switching to the treat-and-extended regimen (p < 0.001). The delayed group showed greater mean BCVA deterioration (p = 0.027) and central subfield thickness (p = 0.037) at 6 months and worse maximum subretinal fluid height (p = 0.022) at 18 months than the on-time group. No difference was observed between the groups in the second year. CONCLUSION the negative effects of delaying anti-VEGF treatment because of the COVID-19 pandemic can be ameliorated by changing the treatment regimen and shortening treatment intervals.

Non-adherence and non-persistence to intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy: a systematic review and meta-analysis. Syst Rev 2023; 12:92. [PMID: 37269003 DOI: 10.1186/s13643-023-02261-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 05/26/2023] [Indexed: 06/04/2023] Open
Abstract
BACKGROUND Intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections play a key role in treating a range of macular diseases. The effectiveness of these therapies is dependent on patients' adherence (the extent to which a patient takes their medicines as per agreed recommendations from the healthcare provider) and persistence (continuation of the treatment for the prescribed duration) to their prescribed treatment regimens. The aim of this systematic review was to demonstrate the need for further investigation into the prevalence of, and factors contributing to, patient-led non-adherence and non-persistence, thus facilitating improved clinical outcomes. METHODS Systematic searches were conducted in Google Scholar, Web of Science, PubMed, MEDLINE, and the Cochrane Library. Studies in English conducted before February 2023 that reported the level of, and/or barriers to, non-adherence or non-persistence to intravitreal anti-VEGF ocular disease therapy were included. Duplicate papers, literature reviews, expert opinion articles, case studies, and case series were excluded following screening by two independent authors. RESULTS Data from a total of 409,215 patients across 52 studies were analysed. Treatment regimens included pro re nata, monthly and treat-and-extend protocols; study durations ranged from 4 months to 8 years. Of the 52 studies, 22 included a breakdown of reasons for patient non-adherence/non-persistence. Patient-led non-adherence varied between 17.5 and 35.0% depending on the definition used. Overall pooled prevalence of patient-led treatment non-persistence was 30.0% (P = 0.000). Reasons for non-adherence/non-persistence included dissatisfaction with treatment results (29.9%), financial burden (19%), older age/comorbidities (15.5%), difficulty booking appointments (8.5%), travel distance/social isolation (7.9%), lack of time (5.8%), satisfaction with the perceived improvement in their condition (4.4%), fear of injection (4.0%), loss of motivation (4.0%), apathy towards eyesight (2.5%), dissatisfaction with facilities 2.3%, and discomfort/pain (0.3%). Three studies found non-adherence rates between 51.6 and 68.8% during the COVID-19 pandemic, in part due to fear of exposure to COVID-19 and difficulties travelling during lockdown. DISCUSSION Results suggest high levels of patient-led non-adherence/non-persistence to anti-VEGF therapy, mostly due to dissatisfaction with treatment results, a combination of comorbidities, loss of motivation and the burden of travel. This study provides key information on prevalence and factors contributing to non-adherence/non-persistence in anti-VEGF treatment for macular diseases, aiding identification of at-risk individuals to improve real-world visual outcomes. Improvements in the literature can be achieved by establishing uniform definitions and standard timescales for what constitutes non-adherence/non-persistence.

Abstract
BACKGROUND Traditionally, visual acuity gain and central retinal thickness have been used to measure outcomes when investigating the efficacy of vascular endothelial growth factor (VEGF) inhibitors for patients with neovascular age-related macular degeneration (nARMD). However, localization of retinal fluid may offer additional prognostic value for treatment. The primary aim of this retrospective clinical audit was to investigate whether the presence and location of subretinal fluid has an effect on the visual outcomes of treatment naïve patients with nARMD treated in the real-world setting with VEGF inhibitors. Secondary aims included investigation of change to visual and anatomical outcomes and investigation of the dosing schedule. METHODS Retrospective observational study of patients attending one suburban and one regional ophthalmology clinic requiring treatment with VEGF inhibitors for nARMD using single-user non-identifiable data from the Fight Retinal Blindness! Registry from 2014 to 2020. Visual acuity (VA) and central subfield thickness (CST) were recorded at baseline, 3, 6, 12 and 24 months. RESULTS Forty-nine eyes of 42 treatment naïve patients were included for analysis (aged 62-89 years). Almost half (49%) presented with a combination of intra- and subretinal fluid at baseline. Intraretinal fluid was present in 75% of eyes but decreased to 22.7% of eyes by 24 months. VA at baseline was 55 letters, and this improved by 6 letters. The change in VA from baseline to 3, 6 and 12 months was statistically significant (p < .05). The mean change in CST from baseline to 3 months was significant (-76 µm). This change was also observed at the other milestones (p < .001). CONCLUSIONS The findings of this study suggest that allowing some subretinal fluid to remain will not affect treatment outcomes.

BMJ Open Ophthalmol 2022; 7:bmjophth-2022-001038. [PMID: 36161843 PMCID: PMC9240889 DOI: 10.1136/bmjophth-2022-001038] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 05/31/2022] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVE To record visual acuity outcomes after 12 months of treatment for neovascular age-related macular degeneration (NvAMD), investigate variation between sites and explore associations with baseline characteristics and care processes. METHODS AND ANALYSIS Anonymised demographic and clinical data were extracted from electronic medical records at treating National Health Service (NHS) Trusts. Associations with acuity outcomes were investigated using multivariate linear and logistic regression. RESULTS Analysis included 9401 eyes (7686 patients) treated at 13 NHS Trusts. From baseline to month 12, median acuity improved from LogMAR 0.50 (IQR 0.30-0.80) to 0.40 (0.22-0.74) and the proportion of eyes with LogMAR ≥0.3 increased from 34.5% to 39.8%. Baseline visual acuity was the strongest predictor of visual acuity outcomes. For each LogMAR 0.1 worsening of baseline acuity, the acuity at 12 months was improved by LogMAR 0.074 (95% CI 0.073 to 0.074) and the odds of a 'poor' acuity outcome was multiplied by 1.66 (95% CI 1.61 to 1.70). Younger age, independent living status, lower socioeconomic deprivation, timely loading phase completion and higher number of injections were associated with better acuity outcomes. Despite case-mix adjustments, there was evidence of significant variation in acuity outcomes between sites. CONCLUSIONS Even after adjustment for other variables, variation in acuity outcomes after NvAMD treatment within the NHS remains. Meaningful comparison of outcomes between different providers requires adjustment for a range of baseline characteristics, not visual acuity alone. Identifying best practice at sites with better outcomes and adapting local care processes are required to tackle this health inequality.

Abstract
BACKGROUND Intravitreal drug delivery belongs to the most common medical procedures, with approximately 1.5 million treatments per year in Germany. However, for this enormous challenge to provision of proper care, there is a lack of empirical data regarding the treatment process and its clinical and subjective effect. MATERIALS AND METHODS This publication presents the development and structure of the Hamburg register for intravitreal therapies (QIVOM). Patients undergoing intravitreal injection therapy were invited to join the register study. Patients were recruited from the Hamburg eye clinics in Heidberg-Nord and Barmbek as well as from the University Medical Center Hamburg-Eppendorf (UKE). Both subjective patient-reported information about the perception of their eye disease and its treatment as well as medical parameters were stored in a central electronic database. RESULTS Of the first 162 study patients (aged 41-95 years), 64% suffered from wet age-related macular degeneration (AMD), 22% had a retinal vein occlusion, and 11% a diabetic macula edema. Disease severity and subjective impairment were heterogenous. Among these patients, 31.8% had a visual acuity above 10/20 on the treated eye compared to 79.1% on the other eye. The reduced ability to read was the most relevant limitation for more than one third of patients. However, 62% were able to drive a vehicle. An improvement of vision through intravitreal therapy was experienced by 45%. CONCLUSION Collection of patient-reported as well as treatment-related data comprises the advantage of the newly created register. This extension of the data basis should deliver new findings in the future and contribute to quality assurance in intravitreal care.

Abstract
Intravitreal injection (IVI) of drugs for treatment of various macular diseases is now one of the most frequently performed surgical procedures worldwide. As mostly chronic diseases are treated, the indications for treatment often mean a continuous treatment over years with a corresponding effort regarding spatial, personnel and financial resources. The diagnosis and indications for treatment are nowadays mainly made by spectral domain optical coherence tomography (SD-OCT). The ability to clinically assess and evaluate a fluorescence angiography is less practiced, although these are still a component of the indications for intravitreal injections. Therefore, it can happen that despite all diligence patients may receive anti-vascular endothelial growth factor (VEGF) treatment, sometimes permanently, based on a misinterpretation of the macular diagnosis or disease activity and these indications, once made, are rarely questioned or retracted. Therefore, the aim of this manuscript is to point out possible and typical misinterpretations in the indications or continuation of IVI treatment with anti-VEGF by means of case studies and to sensitize for differential diagnoses.

Abstract
Background and Objectives: Wet age-related macular degeneration (wAMD) is a chronic, progressive disease of the central part of the retina. Standard treatment for wAMD consists of multiple intravitreal injections of anti-vascular endothelial growth factor drugs. The study goal was to evaluate the three-year effectiveness of wAMD treatment with aflibercept and ranibizumab as part of the therapeutic program in routine clinical practice. Materials and Methods: 1430 patients (possessing 1430 wAMD eyes) with median age of 78.0 years (71.0, 83.0) were enrolled in a non-randomized, retrospective, observational, multicenter study; 804 (56.2%) eyes were treatment-naïve. Therapy was carried out in accordance with the guidelines of the treatment program (the fixed or pro re nata regimen). Results: After the first year of treatment, there was a gain of 2.03 (12.15) letters; after the second, 0.94 (13.72) (p ˂ 0.001); and after the third, 0.17 (14.05) (p ˂ 0.001). There was a significant reduction in the central retinal thickness. In the first year, the patients received 7.00 (5.00, 8.00) injections. In the following years, a significantly lower number of injections (4.00 (2.00, 5.00)) was administered. After the first year, there was a significant difference in the distribution of the best corrected visual acuity according to the Early Treatment Diabetic Retinopathy Study protocol, with more frequent values in the ranges > 35 ≤ 70 for this parameter and > 70 letters in the treatment naïve eye subgroup. After the first year, central retinal thickness in treatment-naïve eyes was significantly reduced. Conclusions: Regular treatment of wet age-related macular degeneration as part of the treatment program achieves functional stabilization and significant morphological improvement over a long-term, three-year follow-up, with significantly fewer injections needed after the first year of treatment.

Abstract
The problem associated with the prevalence of retinal diseases, and age-related macular degeneration (AMD) in particular, is undoubtedly relevant. This aspect is based on steadily growing statistics on morbidity, a high number of randomized controlled trials (RCT) and published real world data (RWD). The analysis of RCT results being published by researchers on 15.05.19 showed 2915 studies were registered on the subject of retinal diseases; that exceeds the number of studies on glaucoma by approximately 1.38 times (2118 studies) and conjunctival lesions by 2.37 times (1230 studies). AMD is one of the leading causes of irreversible vision loss and blindness; its neovascular form leads to blindness in 80-90% of all cases. Even though the topic of nAMD therapy is widely highlighted in modern ophthalmology, today there are many aspects that require targeted solutions. The main controversial issues that determine the complexity of therapy and patient management include discrepancies in determination of reference points (disease activity criteria) for implementation of anti-VEGF dosing regimens, patients' compliance, prioritization issues in treatment, its continuity with potential for the increase of intervals between injections and monitoring visits.

PERSEUS 24-month analysis: a prospective non-interventional study to assess the effectiveness of intravitreal aflibercept in routine clinical practice in Germany in patients with neovascular age-related macular degeneration. Graefes Arch Clin Exp Ophthalmol 2021; 259:2213-2223.

Abstract
PURPOSE To evaluate the real-world effectiveness of intravitreal aflibercept injections in Germany in patients with neovascular age-related macular degeneration over 24 months. METHODS PERSEUS was a prospective, non-interventional cohort study. The primary endpoint was the mean change in visual acuity (VA) from baseline. Secondary endpoints included the proportion of patients with a VA gain or loss of ≥ 15 letters and the frequency of injections and examinations. Patients with regular (bimonthly after 3 monthly injections during year 1 and ≥ 4 injections in year 2) and irregular (any other) treatment were analyzed. The last observation carried forward (LOCF) and the observed cases (OC) approach was applied for primary endpoint analysis to account for missing data. RESULTS 803 patients were considered for effectivity analysis. At month 24, only 38% of the patients were still under observation. The LOCF population included 727, the OC population 279 patients. Treatment-naïve patients improved by 6.3 (LOCF)/8.1 (OC) letters with regular treatment over 24 months but only by 3.3 (LOCF)/3.1 (OC) letters with irregular treatment. The proportion of treatment-naïve patients achieving a VA improvement of ≥ 15 letters was similar between regularly and irregularly treated cohorts. However, considerably more patients in the irregular cohorts experienced a VA worsening of ≥ 15 letters than in the regular cohorts (LOCF: 18.7% vs. 7.4%). CONCLUSIONS Regular IVT-AFL treatment resulted in better VA outcomes than irregular treatment at month 24. However, only a minority of patients received regular treatment over a 2-year period.
