BACKGROUND: Neovascular age-related macular degeneration (nAMD) is a common cause of visual impairment and blindness in the elderly with globally increasing prevalence. Vascular endothelial growth factor inhibitor (anti-VEGF) treatment has improved visual prognosis of nAMD, but continuous treatment may cause anxiety and stress, although increase in visual acuity (VA) may also have positive effects on patients\' quality of life. The health care burden due to frequent treatment and monitoring is apparent, but the effect of anti-VEGF treatment on patients\' quality of life is not fully understood. We evaluated the overall impact of nAMD and its treatment on newly diagnosed patients\' health-related quality of life (HRQoL) in real-world setting.
METHODS: The present prospective cohort study included newly diagnosed nAMD patients treated with anti-VEGF injections at Oulu University Hospital during 2019-2020. Data included parameters from comprehensive ophthalmic examination and fundus imaging, age at diagnosis, sex, comorbidities, visual acuity, and frequency of anti-VEGF injections. HRQoL was assessed by 15D questionnaire at diagnosis, 6 months, and 12 months.
RESULTS: 95 nAMD patients were included. They were 78 ± 8 years old, 56 (59%) were female, and 74 (78%) had more than one comorbidity. The patients received 8 ± 3 anti-VEGF-injections. Visual acuity (VA) improved from 56 ± 18 to 61 ± 24 Early treatment diabetic retinopathy study (ETDRS) letters in 12 months. VA improved > 5 ETDRS letters in 45 (47%), remained stable in 30 (32%) and decreased > 5 letters in 17 (18%) eyes. The mean total 15D score reflecting overall HRQoL decreased from 0.850 ± 0.104 to 0.834 ± 0.103 in 12 months. Decreased HRQoL was associated with baseline best-corrected VA (BCVA) ≥ 70 ETDRS letters (p = 0.023) and more than one comorbidity (p = 0.034). HRQoL regarding visual function increased from 0.765 ± 0.194 to 0.789 ± 0.184 during the 12-month follow-up.
CONCLUSIONS: In real world setting, HRQoL regarding visual function improved in anti-VEGF-treated nAMD patients during the first 12 months after the diagnosis and treatment initiation. Good baseline VA or several comorbidities were associated with decreased overall HRQoL during the follow-up. Despite the effectiveness of anti-VEGF treatment on visual function, several other aspects affecting elderly patients\' everyday life should be considered when nAMD treatment is implemented.

OBJECTIVE: This study aimed to compare the treatment outcomes of patients with neovascular age-related macular degeneration (nAMD) who initially received faricimab or aflibercept treatment using propensity score matching (PSM) to align patient backgrounds.
METHODS: Patients with treatment-naïve nAMD who received either faricimab or aflibercept for three consecutive monthly injections as the loading phase were enrolled in this study. In the 1:1 PSM, sex, age, best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), and AMD subtypes in the pre-treatment state were selected as covariates. We examined the BCVA, CMT, CCT, and remaining fluid at 1-, 2-, and 3-month after the first injection.
RESULTS: After PSM, 43 eyes were included in the faricimab and aflibercept group each. Both groups showed significant improvements in BCVA, CMT, and CCT at 1-, 2-, and 3-month after the initial injection compared with baseline. Meanwhile, no significant differences were observed between the two groups at any time point regarding BCVA, CMT, and CCT. At 1-month, 18.6% of patients in the faricimab group and 41.9% in the aflibercept group demonstrated residual subretinal fluid or intraretinal fluid, with a significant difference between the groups (P = 0.03).
CONCLUSIONS: The BCVA improved after three loading injections of both faricimab and aflibercept. Faricimab may provide a favorable early treatment response in reducing subretinal fluid in a Japanese cohort.

UNASSIGNED: Intravitreal injection of anti-VEGF agents is the first-line treatment for patients with neovascular-age related macular degeneration (nAMD). One unique serious adverse event that may be associated with these agents is intraocular inflammation (IOI). The main purpose of this analysis was to evaluate the potential presence of texture-based radiomics features characterizing heterogeneity within the vitreous compartment of spectral domain optical coherence tomography (SD-OCT) images that may precede or develop in association with IOI and might serve as OCT biomarkers for IOI.
UNASSIGNED: This is a post-hoc analysis of a subset of cases (N = 67) involving IOI, endophthalmitis, and/or retinal vascular occlusion in the phase 3 HAWK trial. These were investigator determined diagnoses that were also confirmed by the safety review committee. Intraocular inflammation was any signs of inflammation within the eye, endophthalmitis was inflammation associated with presumed infection, and retinal vascular occlusions consisted of intraocular inflammation with concurrent vascular occlusions/vasculitis. Out of 67 eyes, 34 belonged to the Safety group with an IOI event and 33 were propensity-matched Controls. A total of 481 texture-based radiomics features were extracted from the vitreous compartment of the SD-OCT scans at pre-IOI time point (i.e., much earlier than the actual event). Most discriminating five features, selected by the Wilcoxon Rank Sum feature selection were evaluated using Random Forest (RF) classifier on the training set ( S t r , N = 47) to differentiate between the two patient groups. Classifier performance was subsequently validated on the independent test set ( S t , N = 20). Additionally, the classifier performance in discriminating the Control and Safety group was also validated on S t at the IOI event timepoint.
UNASSIGNED: The RF classifier yielded area under the Receiver Operating Characteristics curve (AUC) of 0.76 and 0.81 on S t using texture-based radiomics features at pre-IOI and event time-point, respectively.
UNASSIGNED: In this analysis, the presence of a pre-IOI safety signal was detected in the form of textural heterogeneity within the vitreous compartment even prior to the actual event being identified by the investigator. This finding may help the clinicians to assess for underlying posterior inflammation.

OBJECTIVE: This study sought to provide an overview of the current research and further analyze publication trends in the field of vascular endothelial growth factor (VEGF) and anti-VEGF treatment for neovascular age-related macular degeneration (NVAMD).
METHODS: We downloaded all related publications from 2001 to 2020 from the Web of Science Core Collection and conducted a bibliometric analysis using the bibiometrix package in R programming software.
RESULTS: A total of 3717 publications were included in the analysis. The USA contributed the largest number of publications (1443), and achieved the highest number of citations (74,946) and H-index value (28). Johns Hopkins University, USA, was the top institution with the most publications, and Peter A. Campochiaro was the most productive professor at The Wilmer Eye Institute, USA. 9.60% of the total publications were from the Journal of Retinal and Vitreous Diseases. Trend analysis demonstrated that anti-VEGF therapy was introduced in early 2000 after steroids, and the last 2 decades have witnessed the blossom of several anti-VEGF agents. \"Treat-and-extend\" and \"resistance\" were two popular trend topics in recent years.
CONCLUSIONS: The USA occupies a dominant position in the research field of VEGF and anti-VEGF treatments in NVAMD. Steroid administration, photodynamic therapy, and anti-VEGF therapy have been pivotal advances in the treatment of NVAMD patients over the past 2 decades. Limited acting period and resistance are potential investigation directions in future studies.

OBJECTIVE: To determine the proportion and characteristics of eyes with neovascular age-related macular degeneration (nAMD) treated with the Port Delivery System (PDS) with ranibizumab that receive supplemental intravitreal ranibizumab injections because of changes in best-corrected visual acuity (BCVA) or central subfield thickness (CST), or both, and to investigate the safety and efficacy of supplemental injections in eyes with the PDS.
METHODS: Post hoc analyses of data from the phase III, randomized, multicenter, open-label, active-comparator Archway trial (NCT03677934).
METHODS: Adults with nAMD diagnosed within 9 months of screening previously responsive to anti-VEGF therapy.
METHODS: Four hundred eighteen patients were randomized to the PDS with ranibizumab 100 mg/ml with fixed refill-exchanges every 24 weeks (Q24W) or monthly intravitreal ranibizumab 0.5 mg for 96 weeks.
RESULTS: Of the 246 eyes treated with the PDS Q24W and assessed for supplemental treatment criteria, the vast majority (94.6%-98.4%) did not receive supplemental treatment during each retreatment interval, with 87.4% not receiving supplemental treatment at any point during the trial. Of the 31 eyes receiving supplemental treatment, 58.1% received 1 injection and 32.3% received 2. At baseline, eyes receiving supplemental treatment were significantly more likely to have thicker retinas (mean CST, 370.5μm vs. 304.4μm; P = 0.0001), subretinal fluid (54.8% vs. 21.2%; P < 0.0001), and larger pigment epithelial detachment height (215.7 μm vs. 175.9 μm; P = 0.003). These features have previously been associated with difficult-to-treat nAMD. Although BCVA and CST generally remained constant throughout the trial in eyes without supplemental treatment, the small number of eyes receiving supplemental treatment on average lost 1 line of vision from baseline to week 96 (mean, -5.7 ETDRS score letters) and CST continued to increase over time. Absolute BCVA at week 96 was similar irrespective of supplemental treatment status (71.1 and 73.7 letters). Best-corrected visual acuity and CST generally improved within 28 days of supplemental treatment.
CONCLUSIONS: Although the PDS Q24W effectively maintains vision and retinal stability in most eyes with nAMD, a small proportion of patients with features of difficult-to-treat nAMD may benefit from supplemental intravitreal anti-VEGF injections and initial close monitoring is recommended.

This study compares the effectiveness of Conbercept and Aflibercept in treating neovascular age-related macular degeneration (nAMD). Conducted at the First Affiliated Hospital of Chongqing Medical University\'s Ophthalmology Department (May 2020-May 2023), this prospective study enrolled 159 nAMD patients. Participants were randomly divided into two groups: one receiving 0.5 mg Conbercept and the other 2 mg Aflibercept intravitreal injections. Over 12 months, the study, employing a Treat-and-Extend (T&E) regimen, assessed Best-Corrected Visual Acuity (BCVA), Central Retinal Thickness (CRT) changes and injection frequency. Of the 159 patients, 137 (149 eyes) completed the study. No significant age difference was found between the groups (P = 0.331). After 12 months, BCVA improved similarly in both groups (Conbercept: 52.8 ± 18.9, Aflibercept: 52.0 ± 19.7 letters; P = 0.820). CRT reduction was also comparable (Conbercept: 246.3 ± 82.8 µm, Aflibercept: 275.9 ± 114.3 µm; P = 0.079). Injection frequencies averaged 6.9 ± 0.7 (Conbercept) and 6.7 ± 0.7 (Aflibercept; P = 0.255). Subtype analysis revealed Type 1 MNV had higher baseline BCVA and lower CRT, with more frequent injections compared to other types. Both Conbercept and Aflibercept are clinically similar in efficacy for nAMD, with the T&E regimen proving therapeutically effective and potentially reducing patient costs. Anti-VEGF treatment efficacy varies across nAMD subtypes, indicating a potential benefit in tailored treatments for specific subtypes.Clinical trial registration number NCT05539235 (Protocol Registration and Results System).

BACKGROUND: To investigate the clinical effects of double-dose (4 mg) aflibercept treatment in neovascular age-related macular degeneration (nAMD), compared with the standard-dose (2 mg) treatment.
METHODS: A total of 108 eyes from 97 patients with nAMD and received intravitreal aflibercept 2 mg and/or 4 mg treatment were retrospectively reviewed. The changes of central macular thickness (CMT)/ pigmental epithelium detachment height and the recurrence rate of exudation during the 12-month follow-up were compared between the 2 mg group and the 4 mg group. Self-control comparisons (2 mg switch to 4 mg) were also made between two regimens.
RESULTS: Compared with the 2 mg group, tendencies of lower intraretinal fluid incidence and more CMT reduction were observed in the 4 mg group. The later one was also observed when eyes switching from 2 mg to 4 mg regimen. The median remission interval was 5 months in the 4 mg group, 2 months longer than the 3 months in the 2 mg group (P = 0.452). Injections needed in the 4 mg group were 3.644 ± 1.670, less than the 4.286 ± 2.334 injections in the 2 mg group within 12 months as well (P = 0.151). However, no associated vision benefits were gained from the double-douse regimen. No markedly increased-intraocular pressure events, or other adverse events were found in two groups.
CONCLUSIONS: Compared to the aflibercept 2 mg treatment in nAMD, tendencies of anatomic gains and relieving treatment burden were brought by the aflibercept 4 mg treatment. This study may have additional importance, given the further application of high-dose aflibercept in real-world settings.

BACKGROUND: The study aimed to evaluate comparability in terms of efficacy, safety and immunogenicity of Sun\'s ranibizumab biosimilar with reference ranibizumab in patients with neovascular age-related macular degeneration (nAMD).
METHODS: This prospective, randomised, double-blind, two-group, parallel-arm, multicentre, phase 3 comparative study included patients with nAMD ≥ 50 years, randomised (in a 2:1 ratio) in a double-blind manner to receive 0.5 mg (0.05 mL) intravitreal injection of either Sun\'s ranibizumab or reference ranibizumab in the study eye every 4 weeks until week 16 (total of four doses).
RESULTS: Primary endpoint results demonstrated equivalence in the proportion of patients who lost fewer than 15 letters from baseline best-corrected visual acuity (BCVA) to the end of week 16 (99% of patients in Sun\'s ranibizumab and 100% in reference ranibizumab; p > 0.9999), with the proportional difference (90% confidence interval) at -1% (-2.51, +0.61) lying within a pre-specified equivalence margin. Visual acuity improved by 15 or more letters in 43% of Sun\'s ranibizumab group and 37% of the reference ranibizumab group (p = 0.4267). The mean increase in BCVA was 15.7 letters in Sun\'s ranibizumab group and 14.6 letters in the reference ranibizumab group (p < 0.001 within both groups and p = 0.5275 between groups). The mean change in central macular thickness was comparable between groups (p = 0.7946). Anti-ranibizumab antibodies were found in one patient of the reference ranibizumab group, while neutralising antibodies were not found in any patients. Both products were well tolerated.
CONCLUSIONS: Sun\'s ranibizumab biosimilar is found to be therapeutically equivalent to reference ranibizumab in patients with nAMD. There were no additional safety or immunogenicity concerns.
BACKGROUND: CTRI/2020/09/027629, registered on 07 September 2020.

BACKGROUND: 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.
METHODS: 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.

OBJECTIVE: To evaluate 2-year efficacy, durability, and safety of faricimab in the TENAYA Japan subgroup and pooled global TENAYA/LUCERNE cohort of patients with neovascular age-related macular degeneration (nAMD).
METHODS: Subgroup analysis of TENAYA/LUCERNE (NCT03823287/NCT03823300): phase III, multicentre, randomised, active comparator-controlled, double-masked, non-inferiority trials. Treatment-naïve patients aged ≥ 50 years with nAMD were randomised (1:1) to intravitreal faricimab (6.0 mg up to every 16 weeks [Q16W] after 4 initial Q4W doses) or aflibercept (2.0 mg Q8W after 3 initial Q4W doses). Outcomes were assessed through year 2 for the TENAYA Japan subgroup (N = 133) and global pooled TENAYA/LUCERNE cohort (N = 1329).
RESULTS: Vision and anatomic improvements achieved with faricimab at year 1 were maintained over 2 years and were generally comparable between the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Adjusted mean best-corrected visual acuity (BCVA) change from baseline at year 2 for the TENAYA Japan subgroup and global pooled TENAYA/LUCERNE cohort was +7.1 (3.7-10.5) and +4.4 (3.2-5.5) letters in the faricimab arm, respectively, and +5.2 (1.9-8.6) and +4.3 (3.1-5.4) letters in the aflibercept arm, respectively. At week 112, the proportion of faricimab-treated patients on Q16W dosing was 61.0% and 63.1% in the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Faricimab was well tolerated through year 2.
CONCLUSIONS: Year 2 TENAYA Japan subgroup findings for faricimab were generally consistent with the pooled global TENAYA/LUCERNE results in patients with nAMD. Vision and anatomical benefits with faricimab were similar to those with aflibercept but with fewer injections.
