Abstract
PURPOSE To evaluate the impact of the changes in treatment patterns before, during and after the COVID-19 pandemic on best-corrected visual acuity (BCVA) in previously treated neovascular age-related macular degeneration (nAMD) patients. METHODS A multi-centre, retrospective, observational study of consecutive nAMD patients during 2019-2021. Data collected included demographics, BCVA, dates of intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections and clinic visits. RESULTS A total of 1652 eyes of 1652 nAMD patients were included, out of which 850 eyes were assessed in 2019 (pre-COVID-19), 630 eyes were assessed in 2020 (COVID-19) and 974 eyes were assessed in 2021 (post-COVID-19). During the COVID-19 period, the mean number of anti-VEGF injections was significantly lower than the corresponding pre-COVID-19 and post-COVID-19 periods (5.55 compared to 6.13 and 6.60, respectively p < 0.01). A constant lower ratio of injections per patient/month was observed during COVID-19 compared to previous and following years, with a notable decline during March-April, reaching a ratio of 0.4 in 2020 versus 0.65 in 2019 and 0.62 in 2021 (p < 0.01). Baseline BCVA (0.825, p < 0.001), number of injections (-0.007, p < 0.001), gender (-0.027, p = 0.037) and age (0.004, p < 0.001) were shown to be significant predictors of final BCVA. CONCLUSION During the COVID-19 period, patients were treated with significantly less intravitreal anti-VEGF injection compared to the previous year with compensation in the following year. These changes in treatment patterns did not have a significant impact on BCVA outcomes. Age, gender, baseline BCVA and number of injections are predictors of final visual outcomes.

[PMID: 38494487 PMCID: PMC10946101 DOI: 10.1186/s12886-024-03387-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 03/08/2024] [Indexed: 03/19/2024] Open
Abstract
INTRODUCTION In neovascular age-related macular degeneration (nAMD) trials, anti-VEGF injection frequency decreases after the first year, while outcomes remain primarily related to the number of injections. To the best of our knowledge, there are no reports of maintaining the best corrected visual acuity (BCVA) for more than 7 years in extension studies. OBJECTIVE To report a 12-year follow-up of a real-world case of nAMD where BCVA was preserved from declining. CASE DESCRIPTION A 67-year-old Caucasian female presented to our department in June 2010 due to decreased vision in her left eye (LE) within the preceding months. Examination showed a BCVA of 85 letters (L) in the right eye (RE) and 35 L in the LE. Fundus examination showed drusen in the macula of both eyes. Macular edema, loss of the macular lutein pigment, macular hypo/hyperpigmentation were observed in the LE. A diagnosis of Type 2 choroidal neovascular membrane (CNV) in the LE was established and within two months a Type 1 CNV developed in the RE. She undergone 9 injections of bevacizumab (six) and ranibizumab (three) within the first year of treatment in the LE and seven injections of ranibizumab within the first year in the RE. RESULTS The LE had a mean of 5.2 injections per year, and the RE had a mean of 7.5 injections per year, from 2010 to 2022. RE's BCVA dropped by 8L (85L to 77L) and central retinal thickness (CRT) increased by 16 μm (276 μm to 292 μm) while LE's BCVA increased by 28L (35L to 63L) and CRT decreased by 369 μm (680 μm to 311 μm), at the twelfth year. CONCLUSIONS Although the final visual outcome depends on baseline BCVA and lesion type or size, the number of injections is paramount in preserving BCVA and achieving favorable functional outcomes in nAMD, even after 12 years of treatment.

Eye (Lond) 2023; 37:2438-2453. [PMID: 36526863 PMCID: PMC9871156 DOI: 10.1038/s41433-022-02360-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 10/13/2022] [Accepted: 12/06/2022] [Indexed: 12/23/2022] Open
Abstract
The aim of this systematic literature review is twofold, (1) detail the impact of retinal biomarkers identifiable via optical coherence tomography (OCT) on disease progression and response to treatment in neovascular age-related macular degeneration (nAMD) and (2) establish which biomarkers are currently identifiable by artificial intelligence (AI) models and the utilisation of this technology. Following the PRISMA guidelines, PubMed was searched for peer-reviewed publications dated between January 2016 and January 2022. POPULATION Patients diagnosed with nAMD with OCT imaging. SETTINGS Comparable settings to NHS hospitals. STUDY DESIGNS Randomised controlled trials, prospective/retrospective cohort studies and review articles. From 228 articles, 130 were full-text reviewed, 50 were removed for falling outside the scope of this review with 10 added from the author's inventory, resulting in the inclusion of 90 articles. From 9 biomarkers identified; intraretinal fluid (IRF), subretinal fluid, pigment epithelial detachment, subretinal hyperreflective material (SHRM), retinal pigmental epithelial (RPE) atrophy, drusen, outer retinal tabulation (ORT), hyperreflective foci (HF) and retinal thickness, 5 are considered pertinent to nAMD disease progression; IRF, SHRM, drusen, ORT and HF. A number of these biomarkers can be classified using current AI models. Significant retinal biomarkers pertinent to disease activity and progression in nAMD are identifiable via OCT; IRF being the most important in terms of the significant impact on visual outcome. Incorporating AI into ophthalmology practice is a promising advancement towards automated and reproducible analyses of OCT data with the ability to diagnose disease and predict future disease conversion. SYSTEMATIC REVIEW REGISTRATION This review has been registered with PROSPERO (registration ID: CRD42021233200).

Abstract
Objectives The aim of the study was comparison of wet-type age-related macular degeneration in phakic and pseudophakic patients in terms of anatomical and functional success based on the real-life data of Türkiye. Methods The multicenter retrospective real-life study data of the. retinal study group were used in this study. Among 867 eyes of 867 patients were included in the study. Patients were divided into two groups according to the status of the lens; phakic group and pseudophakic group. The follow-up period of the two groups, the number of injections at the 1st, 2nd, and 3rd years, and changes in the central macular thickness (CMT, μ) and visual acuity (VA, logMAR) of the patients at the beginning, 6th, 12th, 24th, and 36th months were examined. Results In our study, the number of injections in the 1st, 2nd, and 3rd years, respectively, was 4.2±2.0, 1.8±1.9, and 1.0±1.7 in the phakic group, and 3.9±2.0, 1.7±1.9, and 0.8±1.4 in the pseudophakic group. When the two groups were compared in terms of the number of injections, there was a statistically significant difference in the 1st year, but there was no significant difference in the 2nd and 3rd years (p=0.001, p=0.350, and p=0.288, respectively). There was no statistically significant difference between the groups in terms of CMT in the baseline, 6th, 12th, 24th, and 36th months (p=0.991, p=0.327, p=0.652, p=0.599, and p=0.873, respectively). Although there was no difference in VA between groups at the beginning (p=0.052), the phakic group showed statistically better VA in controls at 3rd, 6th, 12th, 24th, and 36th months (p=0.001, p=0.001, p=0.000, p=0.000, and p=0.003, respectively). Conclusion Differences in the number of injections and visual results between phakic and pseudophakic patients in wet type AMD may necessitate the creation of different treatment and follow-up protocols.

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.

The Influence of COVID-19 on the Stability of Patients with Neovascular Age-Related Macular Degeneration with Different Treatment Regimens. Adv Ther 2022; 39:1568-1581. [PMID: 34817809 PMCID: PMC8611250 DOI: 10.1007/s12325-021-01993-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 11/09/2021] [Indexed: 01/29/2023]
Abstract
Introduction To explore the impact of coronavirus disease 2019 (COVID-19) on the stability of patients with neovascular age-related macular degeneration (nAMD) receiving the treat and extend (T&E) or the pro re nata (PRN) treatment regimen and to identify indicators that may predict the disease stability of nAMD. Methods This is a retrospective study of patients with nAMD treated at the Second Affiliated Hospital of Harbin Medical University whose treatment schedule was interrupted at least once between 1 February and 31 May 2020. The demographic and clinical characteristics, including the best corrected visual acuity (BCVA), optical coherence tomography (OCT) features, subfoveal choroidal thickness (SFCT), interval between the last injection and the beginning of the pandemic, and the number of anti-vascular endothelial growth factor (VEGF) injections, were analyzed. Results A total of 209 stable patients with nAMD (122 eyes received the T&E regimen; 87 eyes received the PRN regimen) were identified. Compared to those who received the PRN regimen, the patients who received the T&E regimen were more stable during the first visit after COVID-19 (53.3% vs. 33.3%, P = 0.004), the BCVA was significantly better (58.5 letters vs. 56 letters, P = 0.006), and the CRT fluctuated only slightly (15 μm vs. 35 μm, P = 0.001). Furthermore, a multivariate logistic regression analysis showed that stable patients with nAMD with type 1 choroidal neovascularization (CNV) (OR 2.493 [95% CI 1.179–5.272], compared with type 2 CNV; P = 0.017; OR 2.912 [95% CI 1.133–7.485], compared with retinal angiomatous proliferation; P = 0.026) or with pigment epithelial detachment (PED) were more likely to remain stable when treatment was interrupted (OR 0.392 [95% CI 0.181–0.852], compared with no PED; P = 0.018). Conclusion Compared to patients who received the PRN treatment regimen, stable patients with nAMD who received the T&E treatment regimen could better maintain stability when the treatments were suddenly interrupted by the COVID-19 pandemic. In addition, patients with type 1 CNV or patients with PED were more likely to remain stable. At present, the COVID-19 pandemic is becoming increasingly normalized, and the T&E regimen can become a more advanced treatment option for patients undergoing therapy.

Predictive Biomarkers of Age-Related Macular Degeneration Response to Anti-VEGF Treatment. J Pers Med 2021; 11:jpm11121329. [PMID: 34945801 PMCID: PMC8706948 DOI: 10.3390/jpm11121329] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 11/10/2021] [Accepted: 12/06/2021] [Indexed: 02/06/2023] Open
Abstract
Age-related macular degeneration (AMD) is an incurable disease associated with aging that destroys sharp and central vision. Increasing evidence implicates both systemic and local inflammation in the pathogenesis of AMD. Intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents is currently the first-line therapy for choroidal neovascularization in AMD patients. However, a high number of patients do not show satisfactory responses to anti-VEGF treatment after three injections. Predictive treatment response models are one of the most powerful tools for personalized medicine. Therefore, the application of these models is very helpful to predict the optimal treatment for an early application on each patient. We analyzed the transcriptome of peripheral blood mononuclear cells (PBMCs) from AMD patients before treatment to identify biomarkers of response to ranibizumab. A classification model comprised of four mRNAs and one miRNA isolated from PBMCs was able to predict the response to ranibizumab with high accuracy (Area Under the Curve of the Receiver Operating Characteristic curve = 0.968), before treatment. We consider that our classification model, based on mRNA and miRNA from PBMCs allows a robust prediction of patients with insufficient response to anti-VEGF treatment. In addition, it could be used in combination with other methods, such as specific baseline characteristics, to identify patients with poor response to anti-VEGF treatment to establish patient-specific treatment plans at the first visit.

Abstract
Background Neovascular age-related macular degeneration (nAMD) is a leading cause of blindness in older people. Low-grade inflammation is well-known as one of the pathogenic mechanisms in nAMD. Anti-vascular endothelial growth factor (VEGF) therapy is the first-line treatment for nAMD, although macula atrophy (MA) developed under anti-VEGF therapy causes irreversible visual function impairment and is recognized as a serious disorder. Here, we show specific expression patterns of aqueous humor (AH) cytokines in nAMD eyes developing MA under intravitreal injection of aflibercept (IVA) as an anti-VEGF antibody and present predictive cytokines as biomarkers for the incidence of MA in nAMD eyes under IVA treatment. Methods Twenty-eight nAMD patients received three consecutive monthly IVA, followed by a pro re nata regimen for 2 years. AH specimens were collected before first IVA (pre-IVA) and before third IVA (post-IVA). AH cytokine levels, visual acuity (VA), and central retinal thickness (CRT) were measured. Results Two-year incidence of MA was 21.4%. In nAMD eyes developing MA [MA (+) group], pre-IVA levels of monocyte chemoattractant protein-1 (MCP-1), macrophage inflammatory protein (MIP)-1β, VEGF and post-IVA level of MCP-1 were higher than those in nAMD eyes without MA [MA (−) group]. In hierarchical cluster analysis, pre-IVA MCP-1 and VEGF were grouped into the same subcluster, as were post-IVA MCP-1 and CRT. In principal component analysis, principal component loading (PCL) of pre-IVA interferon-γ-inducible protein 10 (IP-10) was 0.61, but PCL of post-IVA IP-10 decreased to −0.09. In receiver operating characteristic analysis and Kaplan–Meier curves, pre-IVA MCP-1, MIP-1β, and VEGF and post-IVA interleukin-6, MCP-1, and MIP-1β were detected as predictive factors for MA incidence. In 2-year clinical course, changes of VA in groups with high levels of pre-IVA MIP-1β (over 39.9 pg/ml) and VEGF (over 150.4 pg/ml) were comparable to those in MA (+) group. Conclusion Substantial loss of IP-10 effects and persistent inflammation contribute to incidence of MA, and screening of AH cytokine levels could be a useful method to predict MA incidence in nAMD eyes under anti-VEGF therapy.

Association between Retinal Thickness Variability and Visual Acuity Outcome during Maintenance Therapy Using Intravitreal Anti-Vascular Endothelial Growth Factor Agents for Neovascular Age-Related Macular Degeneration. J Pers Med 2021; 11:1024. [PMID: 34683165 PMCID: PMC8541068 DOI: 10.3390/jpm11101024] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2021] [Revised: 10/09/2021] [Accepted: 10/11/2021] [Indexed: 01/04/2023] Open
Abstract
Previous studies based on clinical trial data have demonstrated that greater fluctuations in retinal thickness during the course of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy for neovascular age-related macular degeneration (nAMD) is associated with poorer visual acuity outcomes. However, it was unclear whether similar findings would be observed in real-world clinical settings. This study aimed to evaluate the association between retinal thickness variability and visual outcomes in eyes receiving anti-VEGF therapy for nAMD using pro re nata treatment regimen. A total of 64 eyes which received intravitreal anti-VEGF therapy (bevacizumab, ranibizumab or aflibercept) for the treatment of nAMD were evaluated. Variability in spectral-domain optical coherence tomography (OCT) central subfield thickness (CST) was calculated from the standard deviation (SD) values of all follow-up visits after three loading doses from month 3 to month 24. Eyes were divided into quartiles based on the OCT CST variability values and the mean best-corrected visual acuity values at 2 years were compared. At baseline, the mean ± SD logMAR visual acuity and CST were 0.59 ± 0.39 and 364 ± 113 µm, respectively. A significant correlation was found between CST variability and visual acuity at 2 years (Spearman's ρ = 0.54, p < 0.0001), indicating that eyes with lower CST variability had better visual acuity at 2 years. Eyes with the least CST variability were associated with the highest mean visual acuity improvement at 2 years (quartile 1: +9.7 letters, quartile 2: +1.1 letters, quartile 3: -2.5 letters, quartile 4: -9.5 letters; p = 0.018). No significant difference in the number of anti-VEGF injections was found between the four CST variability quartile groups (p = 0.21). These findings showed that eyes undergoing anti-VEGF therapy for nAMD with more stable OCT CST variability during the follow-up period were associated with better visual outcomes. Clinicians should consider adopting treatment strategies to reduce CST variability during the treatment course for nAMD.

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 OF REVIEW Predicting treatment response and optimizing treatment regimen in patients with neovascular age-related macular degeneration (nAMD) remains challenging. Artificial intelligence-based tools have the potential to increase confidence in clinical development of new therapeutics, facilitate individual prognostic predictions, and ultimately inform treatment decisions in clinical practice. RECENT FINDINGS To date, most advances in applying artificial intelligence to nAMD have focused on facilitating image analysis, particularly for automated segmentation, extraction, and quantification of imaging-based features from optical coherence tomography (OCT) images. No studies in our literature search evaluated whether artificial intelligence could predict the treatment regimen required for an optimal visual response for an individual patient. Challenges identified for developing artificial intelligence-based models for nAMD include the limited number of large datasets with high-quality OCT data, limiting the patient populations included in model development; lack of counterfactual data to inform how individual patients may have fared with an alternative treatment strategy; and absence of OCT data standards, impairing the development of models usable across devices. SUMMARY Artificial intelligence has the potential to enable powerful prognostic tools for a complex nAMD treatment landscape; however, additional work remains before these tools are applicable to informing treatment decisions for nAMD in clinical practice.

Abstract
PURPOSE To evaluate the real-world effectiveness, treatment patterns, and safety of ranibizumab in Korean patients with neovascular age-related macular degeneration (nAMD). METHODS LUMINOUS™ is a 5-year, global, prospective, observational, open-label study. Adults aged ≥18 years who were either treatment-naïve or prior-treated were enrolled and treated with ranibizumab 0.5 mg as per the local label. Outcome measures included mean (± standard deviation [SD]) changes from baseline in visual acuity (VA) and central retinal thickness (CRT), and rate of ocular and non-ocular adverse events (AEs). RESULTS Overall, 367 Korean patients with nAMD (152 treatment-naïve and 215 prior-treated) were enrolled. The mean (SD) VA changes from baseline at 1-year were +10.1 (±21.77; P=0.0005) and +1.4 (±15.17; P=0.2142) Early Treatment Diabetic Retinopathy Study letters, with mean numbers of injections of 5.2 and 3.4 in the treatment-naïve and prior-treated groups, respectively. VA gains were greater in patients with lower baseline VA, who received a loading dose, and with polypoidal choroidal vasculopathy (PCV). Multivariate logistic regression analyses demonstrated younger age, worse baseline VA, and those who received loading dose being associated with higher odds of any gain in VA at 1 year (P<0.05). Mean (SD) CRT changes from baseline were -126.7 (±174.90) µm (P<0.0001) and +10.8 (±89.62) µm (P=0.5833) in the treatment-naïve and prior-treated groups, respectively, with greater reductions observed in patients with PCV. Ocular and non-ocular AEs were reported in 8.4% (n=31) and 10.1% (n=37) of patients, respectively. CONCLUSION The LUMINOUS study confirms real-world effectiveness and safety of ranibizumab in Korean patients with nAMD; factors including age, baseline VA, and loading-dose were associated with VA gain at one-year post-treatment.

Abstract
Question What are the differences in treatment outcomes of combination therapy with intravitreal ranibizumab and verteporfin photodynamic therapy vs ranibizumab monotherapy in polypoidal choroidal vasculopathy at month 24? Findings In the EVEREST II randomized clinical trial, combination therapy was superior to monotherapy in terms of adjusted mean best-corrected visual acuity gain and superior in achieving complete absence of indocyanine green hyperfluorescence of polypoidal lesions with fewer ranibizumab injections. Meaning These data suggest that ranibizumab plus prompt verteporfin photodynamic therapy is more effective compared with ranibizumab monotherapy for polypoidal choroidal vasculopathy with reduced treatment burden. Importance The 2-year efficacy and safety of combination therapy of ranibizumab administered together with verteporfin photodynamic therapy (vPDT) compared with ranibizumab monotherapy in participants with polypoidal choroidal vasculopathy (PCV) are unclear. Objective To compare treatment outcomes of ranibizumab, 0.5 mg, plus prompt vPDT combination therapy with ranibizumab, 0.5 mg, monotherapy in participants with PCV for 24 months. Design, Setting, and Participants This 24-month, phase IV, double-masked, multicenter, randomized clinical trial (EVEREST II) was conducted among Asian participants from August 7, 2013, to March 2, 2017, with symptomatic macular PCV confirmed using indocyanine green angiography. Interventions Participants (N = 322) were randomized 1:1 to ranibizumab, 0.5 mg, plus vPDT (combination therapy group; n = 168) or ranibizumab, 0.5 mg, plus sham PDT (monotherapy group; n = 154). All participants received 3 consecutive monthly ranibizumab injections, followed by a pro re nata regimen. Participants also received vPDT (combination group) or sham PDT (monotherapy group) on day 1, followed by a pro re nata regimen based on the presence of active polypoidal lesions. Main Outcomes and Measures Evaluation of combination therapy vs monotherapy at 24 months in key clinical outcomes, treatment exposure, and safety. Polypoidal lesion regression was defined as the absence of indocyanine green hyperfluorescence of polypoidal lesions. Results Among 322 participants (mean [SD] age, 68.1 [8.8] years; 225 [69.9%] male), the adjusted mean best-corrected visual acuity (BCVA) gains at month 24 were 9.6 letters in the combination therapy group and 5.5 letters in the monotherapy group (mean difference, 4.1 letters; 95% CI, 1.0–7.2 letters; P = .005), demonstrating that combination therapy was superior to monotherapy by the BCVA change from baseline to month 24. Combination therapy was superior to monotherapy in terms of complete polypoidal lesion regression at month 24 (81 of 143 [56.6%] vs 23 of 86 [26.7%] participants; P < .001). Participants in the combination group received fewer ranibizumab injections (median, 6.0 [interquartile range (IQR), 4.0-11.0]) than the monotherapy group (median, 12.0 [IQR, 7.0-17.0]) up to month 24. The combination group required a median of 2.0 (IQR, 1.0-3.0) vPDT treatments for 24 months, with 75 of 168 participants (44.6%) requiring only 1 vPDT treatment. Conclusions and Relevance The 24-month data findings confirm that ranibizumab therapy, given as monotherapy or in combination with vPDT, is efficacious and safe for treatment of PCV. Combination therapy with vPDT added to ranibizumab achieved superior BCVA gain, increased odds of complete polypoidal lesion regression, and fewer treatment episodes compared with ranibizumab monotherapy. Trial Registration ClinicalTrials.gov Identifier: NCT01846273.

Abstract
Aim.To study predictive factors for functional outcome of aflibercept intravitreal antiangiogenic therapy in patients with neovascular age-related macular degeneration (nAMD).
Material and methods.Thirty-six treatment naive nAMD patients (45 eyes, 26 females and 10 males, with a mean age of 74.4 10.9 years) were included in this study. All patients received 3 monthly aflibercept injections followed by 4 bimonthly aflibercept injections. Demographic characteristics, baseline best corrected visual acuity (BCVA), central retinal thickness (CRT), and structural retinal changes on optical coherence tomography (OCT) scans were evaluated for the correlation with BCVA after 10 months follow-up.
Results.At the end of the follow-up period, the mean BCVA increased statistically significantly from 31 15 (~0.32) letters at baseline to 37 14 (~0.4) letters (p= 0.003). CRT at baseline and at the end of follow-up was 357 110 and 269 70 m (p 0.001), respectively. Final BCVA correlated statistically significantly with baseline BCVA (r= 0.62,p 0.0001), baseline CRT (r= 0.48,p= 0.001), and disease duration from the appearance of complaints until the therapy start (r= 0.32,p= 0.03). Structural macular changes on the OCT scans were not related to final BCVA (p 0.05) apart from the status of the ellipsoid zone (p 0.001). Final BCVA was statistically significantly lower in males than in females (34.7 14.0 (~0.4) and 45.0 9.2 (~0.63) letters, respectively,p= 0.03).
Conclusion.Baseline visual acuity, gender, CRT, disease duration from the appearance of complaints until the therapy start, and status of the ellipsoid zone are predictive for the functional outcome in wet AMD patients.

Abstract
Since the determination of the first molecular models of proteins there has been interest in creating proteins artificially, but such methods have only become widely successful in the last decade. Gradual improvements over a long period of time have now yielded numerous examples of non-natural proteins, many of which are built from repeated elements. In this review we discuss the design of such symmetrical proteins and their various applications in chemistry and medicine.

Abstract
PURPOSE The aim of this study was to evaluate the effect of vitreous reflux (VR) on the short-term effect of intravitreal ranibizumab injection. MATERIALS AND METHODS The study included 181 eyes of 81 age-related macular degeneration (AMD) and 100 diabetic macular edema (DME) patients. Treatment response was evaluated by measuring central macular thickness (CMT) as well as 1 mm and 3 mm central macular thicknesses (MT1 and MT3). Patients were grouped as; Group 1: no VR, Group 2: <3 mm VR, and Group 3: >3 mm VR according to conjunctival bleb diameters. The data were analyzed using variance, correlation and regression analyses. RESULTS In AMD patients, reduction of CMT values following the treatment were 88.3 ± 110.6 µm in Group 1, 85.6 ± 158.7 µm in Group 2, and 93.1 ± 92.2 µm in Group 3. Likewise, in DME patients, it was 82.4 ± 88.4 µm, 72.9 ± 109.9 µm, and 73.7 ± 113.7 µm, respectively. Reduction of MT1 values after the treatment were 47.4 ± 72.6 µm, 36.0 ± 131.9 µm, and 36.7 ± 114.4 µm in AMD patients, and 33.3 ± 72.5 µm, 36.6 ± 90.2 µm, and 46.9 ± 83.4 µm in DME patients. In all comparisons among groups of VR, macular thickness (MT) change did not exhibit significant difference following an intravitreal ranibizumab treatment (p > .05). CONCLUSION We found that the increase in VR amount did not adversely affect the decrease in MT after intravitreal ranibizumab treatment in AMD and DME patients.

Abstract
<b><i>Introduction:</i></b> The aim of this study is to assess and compare the long-term clinical efficacy of anti-VEGF drugs using the Imaculaweb registry. <b><i>Methods:</i></b> In this observational study based on the Imaculaweb registry, outcome measures were the number of injections, the change in mean visual acuity (VA) and central macular thickness (CMT), and the time between diagnosis and the first injection. <b><i>Results:</i></b> In total, 126 eyes of 109 patients were included in the study. The mean VA was 49.4 ± 21.4, 54.1 ± 22.2, 51.6 ± 24.9, and 48.3 ± 25.7 letters at baseline and at the 1-, 2-, and 3-year follow-ups, respectively. Significant VA increases (<i>p</i> = 0.0002 for the first year and <i>p</i> = 0.045 for the second year) were documented at years 1 and 2 but not at year 3 (<i>p</i> = 0.8). The mean number of injections was 5.2, 2.6, and 2.3 at the 1-, 2-, and 3-year follow-ups, respectively. In the first year, 30% of the patients received at least 7 injections, while only 6.4% received <3 injections. CMT decreased significantly during the overall follow-up period, and intra- and subretinal fluid decreased (<i>p</i> < 0.0001). <b><i>Conclusion:</i></b> Imaculaweb turned out to be an effective tool to collect and share clinical data as well as to monitor patient outcome.

Abstract
Background/objectives To investigate the association between optical coherence tomography (OCT) markers of lesion activity and changes in visual acuity (VA) during anti-vascular endothelial growth factor (anti-VEGF) therapy of eyes diagnosed with neovascular age-related macular degeneration (nAMD); and how VA and OCT markers are considered in physicians’ decision to retreat with anti-VEGFs. Subjects/methods Retrospective, non-comparative, non-randomised cohort study involving electronic medical record data collected from 1190 patient eyes with nAMD diagnosis at two sites in the United Kingdom. Two sub-cohorts consisting of 321 and 301 eyes, respectively, were selected for analyses. Results In 321 eyes, absence of IRF or SRF at ≥2 clinic visits resulted in a gain of five ETDRS letters from baseline, compared with two letters gained in eyes with <2 clinic visits with absence of IRF (p = 0.006) or SRF (p = 0.042). Anti-VEGF treatment was administered at 421 clinic visits, and 308 visits were without treatment. Comparing treatment visits with non-treatment visits, the maximum difference in frequency of OCT markers of lesion activity were for intraretinal fluid (IRF; 24% versus 5%) and subretinal fluid (SRF; 32% versus 5%). Pigment epithelial detachment (PED) was reported in 58% of treatment visits compared with 36% in non-treatment visits. VA loss was not a consistent trigger for retreatment as it was present in 63% of injection visits and in 49% of non-injection visits. Conclusions Retreatment decision making is most strongly influenced by the presence of IRF and SRF and less by the presence of PED or VA loss.

Abstract
Many conditions affecting the heart, brain, and even the eyes have their origins in blood vessel pathology, underscoring the role of vascular regulation. In age-related macular degeneration (AMD), there is excessive growth of abnormal blood vessels in the eye (choroidal neovascularization), eventually leading to vision loss due to detachment of retinal pigmented epithelium. As the advanced stage of this disease involves loss of retinal pigmented epithelium, much less attention has been given to early vascular events such as endothelial dysfunction. Although current gold standard therapy using inhibitors of vascular endothelial growth factor (VEGF) have achieved initial successes, some drawbacks include the lack of long-term restoration of visual acuity, as well as a subset of the patients being refractory to existing treatment, alluding us and others to hypothesize upon VEGF-independent mechanisms. Against this backdrop, we present here a nonexhaustive review on the vascular underpinnings of AMD, implications with genetic and systemic factors, experimental models for studying choroidal neovascularization, and interestingly, on both endothelial-centric pathways and noncell autonomous mechanisms. We hope to shed light on future research directions in improving vascular function in ocular disorders.

Garweg JG. Twelve-week dosing with Aflibercept in the treatment of neovascular age-related macular degeneration. Clin Ophthalmol 2019; 13:1289-1295. [PMID: 31409968 PMCID: PMC6650619 DOI: 10.2147/opth.s185756] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Accepted: 06/11/2019] [Indexed: 12/16/2022] Open
Abstract
Purpose To review published evidence for a treatment interval extension to ≥12-weeks in neovascular macular degeneration treated with intravitreal Aflibercept. Methods A systematic search was performed in the NCBI/PubMed database to identify pro- and retrospective studies retrieved by the key terms <exudative> or <neovascular> and <AMD> or <age-related macular degeneration> AND <intravitreal therapy> AND <Aflibercept> and included all papers that used a treat-and-extend (T&E) protocol including a loading phase of 3 intravitreal anti-VEGF injections and a minimal follow-up of 2 years. Disease stability was defined as the absence of any intraocular and absence or stability of subretinal fluid and pigment-epithelial detachment. Results Four studies were identified that reported information pertaining to disease stability or treatment extension beyond 12 weeks under intravitreal Aflibercept therapy including 1,102 eyes in total. Following a T&E protocol, a mean of 62.9% achieved disease stability and a 6.9 letter gain based on 11.9 injections over 24 months of Aflibercept treatment. As much as 43.0% of all eyes or 64.1% of the eyes with stable disease were maintained on ≥12-weekly injection intervals. Conclusions A consequent treatment with a null tolerance for intraretinal fluid is prerequisite to induce stability and maintain visual gain after the loading phase. Using Aflibercept in a T&E protocol, disease stability and interval extension to ≥12 weeks were reported in 43% of the eyes by end of the second year with less injections, but similar results as under fix dosing. A lower treatment burden strongly argues for an individualized proactive treatment regimen.

Abstract
Emerging anti-vascular endothelial growth factor (anti-VEGF) therapies for neovascular age-related macular degeneration (nAMD) have revolutionised medical retina practice and the management and eventual outcome of nAMD. Recent research has focused on evaluating and comparing the efficacy of the two most widely employed anti-VEGF agents, bevacizumab and ranibizumab; however, a subgroup of patients with nAMD demonstrates a suboptimal response to standard therapy. We have therefore conducted a review of pertinent studies published until August 2018 which have documented the clinical efficacy when switching to a different anti-VEGF. Evidence on baseline disease characteristics, injection frequency and disease outcome has been obtained for patients treated with ranibizumab 0.5 mg and/or bevacizumab 1.25 mg and were switched to aflibercept 2 mg. Our review identified 45 studies investigating switching to aflibercept. Our review showed a clear anatomical benefit after the switch in terms of central retinal thickness and pigment epithelium detachment characteristics, whereas the functional outcomes were variable. Remarkable heterogeneity was documented among the relevant studies with regard to several factors including the baseline characteristics of the cohorts, the non-response definition and previous treatment protocols. Larger prospective trials with appropriate control arms are therefore required to elucidate the potential benefit when switching between anti-VEGF agents in refractory nAMD.
