Purpose: To evaluate 2-year efficacy, durability, and safety of the bispecific antibody faricimab, which inhibits both angiopoietin-2 and VEGF-A., Design: TENAYA (ClinicalTrials.gov identifier, NCT03823287) and LUCERNE (ClinicalTrials.gov identifier, NCT03823300) were identically designed, randomized, double-masked, active comparator-controlled phase 3 noninferiority trials., Participants: Treatment-naive patients with neovascular age-related macular degeneration (nAMD) 50 years of age or older., Methods: Patients were randomized (1:1) to intravitreal faricimab 6.0 mg up to every 16 weeks (Q16W) or aflibercept 2.0 mg every 8 weeks (Q8W). Faricimab fixed dosing based on protocol-defined disease activity at weeks 20 and 24 up to week 60, followed up to week 108 by a treat-and-extend personalized treatment interval regimen., Main Outcome Measures: Efficacy analyses included change in best-corrected visual acuity (BCVA) from baseline at 2 years (averaged over weeks 104, 108, and 112) and proportion of patients receiving Q16W, every 12 weeks (Q12W), and Q8W dosing at week 112 in the intention-to-treat population. Safety analyses included ocular adverse events (AEs) in the study eye through study end at week 112., Results: Of 1326 patients treated across TENAYA/LUCERNE, 1113 (83.9%) completed treatment (n = 555 faricimab; n = 558 aflibercept). The BCVA change from baseline at 2 years was comparable between faricimab and aflibercept groups in TENAYA (adjusted mean change, +3.7 letters [95% confidence interval (CI), +2.1 to +5.4] and +3.3 letters [95% CI, +1.7 to +4.9], respectively; mean difference, +0.4 letters [95% CI, -1.9 to +2.8]) and LUCERNE (adjusted mean change, +5.0 letters [95% CI, +3.4 to +6.6] and +5.2 letters [95% CI, +3.6 to +6.8], respectively; mean difference, -0.2 letters [95% CI, -2.4 to +2.1]). At week 112 in TENAYA and LUCERNE, 59.0% and 66.9%, respectively, achieved Q16W faricimab dosing, increasing from year 1, and 74.1% and 81.2%, achieved Q12W or longer dosing. Ocular AEs in the study eye were comparable between faricimab and aflibercept groups in TENAYA (55.0% and 56.5% of patients, respectively) and LUCERNE (52.9% and 47.5% of patients, respectively) through week 112., Conclusions: Treat-and-extend faricimab treatment based on nAMD disease activity maintained vision gains through year 2, with most patients achieving extended dosing intervals., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Purpose: To investigate associations between residual subretinal fluid (rSRF) volumes, quantified using artificial intelligence and treatment outcomes in a subretinal fluid (SRF)-tolerant treat-and-extend (T&E) regimen in neovascular age-related macular degeneration., Methods: Patients enrolled in the prospective, multicenter FLUID study randomized in an SRF-tolerant T&E regimen were examined by spectral-domain optical coherence tomography and tested for best-corrected visual acuity (BCVA). Intraretinal fluid and SRF volumes were quantified using artificial intelligence tools. In total, 375 visits of 98 patients were divided into subgroups: extended intervals despite rSRF and extended intervals without fluid. Associations between BCVA change, SRF volume, subgroups, and treatment intervals were estimated using linear mixed models., Results: In extended intervals despite rSRF, increased SRF was associated with reduced BCVA at the next visit in the central 1 mm (-0.138 letters per nL; P = 0.014) and 6 mm (-0.024 letters per nL; P = 0.049). A negative association between increased interval and BCVA change was found for rSRF in 1 mm and 6 mm (-0.250 and -0.233 letter per week interval, respectively; both P < 0.001). Extended intervals despite rSRF had significantly higher SRF volumes in the central 6 mm at the following visit (P = 0.002)., Conclusion: Artificial intelligence-based analysis of extended visits despite rSRF demonstrated increasing SRF volumes associated with BCVA loss at the consecutive visit. This negative association contributes to the understanding of rSRF volumes on treatment outcomes in neovascular age-related macular degeneration.

Purpose: To assess visual function outcomes to 48 weeks in patients with bilateral geographic atrophy (GA) secondary to age-related macular degeneration included in 2 interventional clinical trials: relationship to baseline lesion size, outcomes by baseline lesion characteristic subgroups, and correlation of visual function outcomes with GA area., Design: The Chroma and Spectri studies (ClinicalTrials.gov identifiers, NCT02247479 and NCT02247531, respectively) were identically designed phase 3, double-masked, multicenter, randomized, sham injection-controlled clinical trials that evaluated intravitreal lampalizumab in GA., Participants: Eligible patients were 50 years of age or older with well-demarcated bilateral GA (lesion size, 1-7 disc areas) without evidence of or previous treatment for choroidal neovascularization in either eye and best-corrected visual acuity (BCVA) letter score of 49 letters or more (≥1 GA lesion within 250 μm of foveal center if BCVA ≥79 letters)., Methods: Patients (pooled n = 1881) were randomized 2:1:2:1 to lampalizumab every 4 weeks, sham every 4 weeks, lampalizumab every 6 weeks, or sham every 6 weeks. Sham arms were pooled for analysis., Main Outcome Measures: Functional end points included change in BCVA from baseline to week 48, low-luminance visual acuity, mesopic microperimetry (number of absolute scotomatous points, mean macular sensitivity), binocular and monocular maximum reading speed, and 2 validated patient-reported outcome measures: Functional Reading Independence Index and 25-item National Eye Institute Visual Function Questionnaire., Results: Enlargement of GA area, approximately 2 mm 2 /year on average across all treatment groups in each study, was accompanied by overall deterioration in all functional end points. No statistically significant differences were found between lampalizumab or sham arms for changes from baseline in functional assessment scores. Of visual function tests, only microperimetry outcomes were correlated moderately with GA lesion area when assessed cross-sectionally at baseline and week 48., Conclusions: Chroma and Spectri provide a unique data set of functional end points in GA that are relevant for future clinical trials. Patients with bilateral GA experienced a consistent decline in visual function over 48 weeks, but measures of visual function were not correlated strongly with GA lesion area. It is not possible to predict visual function outcomes from GA lesion size., (Copyright © 2020 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.)

Purpose: To explore various methods for assessing the early response to vascular endothelial growth factor (VEGF) inhibitors for neovascular age-related macular degeneration and investigate their association with 3-year visual acuity (VA) outcomes., Design: Database study, prospectively designed., Participants: Treatment-naïve eyes in the Fight Retinal Blindness! registry that commenced anti-VEGF therapy between January 1, 2007, and March 1, 2014, that received 3 anti-VEGF injections within the first 3 months., Methods: The early response was defined as occurring up until the fourth injection. Various early response metrics were explored: (1) achieving good VA (≥70 letters; Snellen equivalent, 20/40), (2) absolute change in VA from baseline, (3) time to first grading of the choroidal neovascular lesion as inactive, and (4) maximum rate of VA change between successive injections., Main Outcome Measures: Proportion of eyes achieving ≥70 letters 3 years., Results: This study included 2051 treatment-naïve eyes from 1828 patients. Achieving good vision at 3 years was associated significantly with (1) having good vision by the fourth injection (VA ≥70 vs. VA <70 letters: odds ratio [OR], 9.8; 95% confidence interval [CI], 6.5-14.7), (2) small (1-5 letters) or large (>5 letters) early VA gains (vs. early VA loss: OR, 1.8; 95% CI, 1.2-2.6; P = 0.002; and OR, 1.8; 95% CI, 1.3-2.5; P < 0.001), (3) fewer injections until first grading of lesion inactivity (≤3 vs. >3 injections: OR, 1.6; 95% CI, 1.2-2.1; P < 0.001), (4) gradual change (between -4 and 4 letters) or rapid gains (≥5 letters) between successive injections (vs. rapid loss: OR, 1.7; 95% CI, 1.1-2.6; P = 0.015; and OR, 1.6; 95% CI, 1.1-2.3; P = 0.018). Eyes that achieved small or large early gains had similar vision at 3 years (65.0 and 64.7 letters, respectively) and had better vision than eyes with early VA loss (57.2 letters)., Conclusions: Attainment of good vision by the fourth injection was associated strongly with 3-year visual outcomes, whereas other early response parameters showed a moderate association. The early response during the initial 3 monthly injections can be a useful guide for subsequent treatment decisions., (Copyright © 2018 American Academy of Ophthalmology. Published by Elsevier Inc.

Importance: Improved vision self-monitoring tools are required for people at risk of neovascular complications from age related macular degeneration (AMD)., Background: to report the self-monitoring habits of participants with intermediate AMD using the Amsler grid chart, and the use of personal electronic devices and gameplay in this over 50 year old cohort., Design: single-centre descriptive study carried out at the Centre for Eye Research (CERA), Melbourne, Australia., Participants: 140 participants over 50 years of age, with a diagnosis of intermediate AMD and best-corrected visual acuity (BCVA) of ≥6/12 in each eye., Methods: structured questionnaire survey of participants who were enrolled in natural history of AMD studies at CERA., Main Outcome Measures: frequency of vision self-monitoring using the Amsler grid chart, and frequency of general use of personal electronic devices and gameplay., Results: Of 140 participants with mean age of 70.5 years, 83.6% used an Amsler grid chart, but only 39.3% used it once per week. Most participants (91.4%) used one or more personal electronic devices. Of these, over half (54.7%) played games on them, among whom 39% played games once a day. Of participants aged 50-69 years, 92% (95%CI 85.1-98.9) were willing to play a game to monitor their vision, compared to 78% (95%CI 69.0-87.0) of those aged 70 years and older (P < 0.05)., Conclusions and Relevance: a large proportion of AMD patients already use personal electronic devices. Gamification techniques are likely to increase compliance with self-monitoring, leading to earlier detection in the next generation of patients with neovascular AMD., (© 2017 Royal Australian and New Zealand College of Ophthalmologists.)

Purpose: To report 24-month outcomes of a treat and extend (T&E) regimen using aflibercept in eyes with neovascular age-related macular degeneration., Methods: This was a database observational study that included treatment-naive eyes with neovascular age-related macular degeneration tracked by the Fight Retinal Blindness! outcome registry completing 24 months of sole monotherapy with aflibercept treatment under a T&E regimen between November 1, 2012 and January 31, 2014. Locally weighted scatterplot smoothing curves were used to display visual acuity outcomes. Main outcome measures were change in visual acuity at 24 months and number of injections and visits during the study period., Results: The study population, identified by reviewing the database, consisted of 136 eyes from 123 patients completing 24 months of follow-up on aflibercept. Mean (SD) age was 77.2 (7.0) years, 59% were female. Mean visual acuity increased from 61.4 (∼20/60; SD 17.4) letters at baseline to 67.4 (∼20/45; SD 17.7) letters at 24 months (+6.0 letters [95% confidence interval: 3.3-8.5]; P < 0.001). From baseline to 24 months, the proportion of eyes with visual acuity ≥70 letters (20/40) increased (40%-58%, P < 0.001) and the proportion of eyes with visual acuity ≤35 letters (20/200) remained the same (10%; P = 0.547). Ninety-eight per cent of eyes starting with visual acuity ≥70 letters (20/40) were able to maintain this up to 24 months. From the first to the second year of treatment, the mean number of injections (7.8 [2.1] vs. 5.7 [2.6]; P < 0.001) and visits (8.7 [1.7] vs. 6.5 [2.4]; P < 0.001) decreased for eyes completing 24 months of treatment. When data from 60 eligible eyes that did not complete 2 years follow-up, along with 14 eyes that switched to ranibizumab, were included using last observation carried forward, the mean change in visual acuity from baseline was +5.6 letters (95% confidence interval: 3.3-7.7)., Conclusion: These data indicate that eyes treated with aflibercept, as a sole therapy, in routine clinical practice with a T&E regimen can achieve good visual outcomes while decreasing the burden of treatments and clinic visits.

Aims: To examine 12-month outcomes of eyes switching from intravitreal ranibizumab to aflibercept for neovascular age-related macular degeneration (nAMD)., Methods: Database observational study of eyes with nAMD tracked by the Fight Retinal Blindness outcome registry that received ranibizumab for at least 12 months before switching to aflibercept and followed for at least 12 months after the switch. Visual acuity (VA) recorded at 12 months after the switch was analysed using locally weighted scatterplot smoothing curves. Lesion activity was graded according to a prospectively identified definition. Main outcomes were change in VA and treatment intervals 12 months after the treatment switch. Secondary outcomes included change in activity grading, effect of duration of treatment before switching and analysis of eyes that switched back., Results: A total of 384 eyes switched from ranibizumab to aflibercept after a mean duration of 39.8 months on the original treatment. The mean VA did not change from the time of switching treatment (63.4, SD 15.9 logarithm of the minimum angle of resolution letters) to 12 months later (63.3, SD 16.7). While 10% of eyes gained 10 or more letters 12 months after the switch, 13% lost the same amount. The mean number of injections decreased by around one injection in the 12 months after switching (p<0.001), with a decrease in the proportion of choroidal neovascular membrane lesions that were graded as active. Eyes that had been treated for the longest time (49 or more months) before switching had worse vision at the point of switch but neither change in VA nor treatment interval was different between groups. The small proportion (6.9%) of eyes that switched back again to ranibizumab had already lost a mean of 5.2 letters from the first switch to the switch back and continued to lose vision at a similar rate for at least 6 months., Conclusions: The mean VA of eyes that switched treatments from ranibizumab to aflibercept was not different 12 months later. There was a modest increase in treatment intervals and a somewhat greater proportion of eyes that were graded as inactive after the switch., Competing Interests: JJA, RG, APH, ILM and MCG are members of advisory boards for Novartis and Bayer.

Purpose: To analyze visual acuity (VA) outcomes before and after preplanned treatment regimen change in the VIEW studies at week 52 (W52)., Design: Multiple post hoc analyses for retrospectively defined subgroups in 2 multicenter, multinational, double-masked trials., Participants: Two thousand four hundred fifty-seven neovascular age-related macular degeneration (AMD) patients., Methods: Patients were randomized to treatment with 0.5 mg ranibizumab given monthly, a 0.5-mg or 2-mg intravitreal aflibercept injection given monthly, or 2 mg intravitreal aflibercept given every other month, after 3 initial monthly doses, up to W52. From W52 through W96, patients received their original dosing assignment using a capped pro re nata (PRN) regimen, with defined retreatment criteria based on VA and morphologic signs of disease activity and mandatory dosing at least every 12 weeks., Main Outcome Measures: Best-corrected VA (BCVA) and optical coherence tomography assessments were mandatory at all visits from baseline to W96. Outcomes were changes in BCVA and central retinal thickness. Outcomes were evaluated in all patients who completed 2 years of the VIEW studies using the last observation carried forward method for missing data at interim visits., Results: After W52, approximately 20% of patients lost 5 Early Treatment Diabetic Retinopathy Study (ETDRS) letters or more across all treatment arms with PRN treatment. Patients who met the retreatment criterion of loss of 5 ETDRS letters or more in the first quarter of the PRN dosing phase did not recover; mean final VA loss across the 4 study arms was -4.4 to -5.8 letters. Outcomes of these patients up to W52 were indistinguishable from those of the overall population. There were no differences between groups in serious ocular adverse events or Anti-Platelet Trialists' Collaboration arterial thromboembolic events through W96., Conclusions: These analyses suggest that there are subgroups of patients for whom VA outcomes in the second year of the VIEW studies were less stable than in the first year and for whom W52 seems to be an important inflection point. Although alternate reasons specific to the nature of the underlying AMD cannot be fully excluded, the switch in treatment regimen at W52 is a plausible explanation., (Copyright © 2015 American Academy of Ophthalmology.

PurposeTo assess retinal vascular calibre changes in eyes with neovascular age-related macular degeneration (AMD), treated with intravitreal anti-vascular endothelial growth factor agents, over a 1-year period and compare any such changes to untreated fellow eyes.MethodsTreatment naïve patients with neovascular AMD received three consecutive intravitreal injections of ranibizumab, followed by a pro re nata dosing regimen up to 1 year, with the aim of maintaining a 'fluid-free' macula. Retinal arteriolar and venular calibre was measured from digital fundus photographs at baseline and at three monthly intervals to 1 year, and summarised as central retinal artery equivalent (CRAE) and central retinal venular equivalent (CRVE), respectively.ResultsA total of 53 injected eyes and 41 fellow, non-injected eyes were analysed. At baseline, there were no differences in retinal vascular calibre between injected and non-injected eyes (mean CRAE (SD) 144.93 (14.07) vs 145.74 (13.10) μm, P=0.80 and mean CRVE (SD) 216.23 (25.93) vs 219.91 (22.82) μm, P=0.53). Over a 12-month period, retinal venular calibre dilatation occurred in injected eyes (mean CRVE change +5.71 (14.71) μm, P=0.007), with no change in retinal arterioles, +0.69 (14.71) μm, P=0.68. In non-injected eyes, arteriolar narrowing occurred as a whole, mean CRAE change −4.20 (7.00) μm, P=0.001, over 12 months, with a trend for narrowing in venules, −2.16 (11.56) μm, P=0.28. In injected eyes, after controlling for covariates, the changes in CRVE over 12 months mirrored improvements in macular thickness, −0.06 (−0.005, −0.11) μm, P=0.04, and visual acuity, +9.66 (−0.30, +19.32) μm, P=0.06.ConclusionIntravitreal ranibizumab significantly dilated retinal venules after a 1-year period.

Purpose(1) To evaluate the spectrum of BEST1mutations within Australian Best Disease or vitelliform macular dystrophy (VMD) pedigrees, including any novel mutations; (2) to analyse the range of clinical presentations of this cohort; (3) to determine any possible genotype-phenotype correlations and (4) to compare clinical data of patients with phenotypic VMD, both with and without a BEST1mutation.Patients and methodsPatients with suspected VMD were referred to clinical centres for ophthalmological assessment and genetic screening. When a mutation was identified in a proband, further family members were invited for clinical and genetic screening.ResultsWe identified 42 patients with one of 13 BEST1mutations. Seven mutations were novel. There were a further 14 probands in whom a BEST1mutation was not identified. Median visual acuity in both VMD (mutation positive) and clinical VMD (no BEST1mutation identified) groups reached driving standards (6/12 or better).ConclusionWe did not identify any firm genotype-phenotype correlations in our Australian VMD pedigrees, in which there was a spectrum of BEST1mutations and marked variation in clinical presentation. Genetic screening remains the gold standard for VMD diagnosis. Patients should be counselled that visual acuity might remain at or above driving standards in at least one eye even in the presence of a BEST1mutation. [ABSTRACT FROM AUTHOR]

BackgroundAlthough randomized clinical trials (ANCHOR and MARINA) have shown excellent results of ranibizumab treatment in patients with neovascular age-related macular degeneration (AMD), it is unclear whether such an outcome is achievable in daily practice. We evaluated the results of ranibizumab treatment for neovascular AMD in clinical practice in Australia.MethodsA retrospective chart review of patients in four practices injected with ranibizumab in 2006 for AMD. Patients who had been diagnosed with subfoveal choroidal neovascular membrane in the preceding 6 months and had completed at least 6 months follow-up were enrolled. No standard treatment protocols were required. The main outcome measure was visual acuity (VA) at 6 and 12 months.ResultsA total of 158 patients fulfilled the entry criteria. The mean baseline VA (decimal) was 0.35±0.21 (Snellen equivalent 6/17). At 6 months, the mean VA improved to 0.46±0.27 (6/13) and remained stable until month 12 (0.48±0.30). The improvement in VA between baseline and months 6 and 12 was statistically significant (P<0.0001). Both the mean and the median number of injections were four in the first 6 months and nine at 12 months. VA results were comparable with those of the ANCHOR and MARINA trials, and were achieved with a lower number of injections (P<0.0001).ConclusionVA results achieved in daily clinical practice using ranibizumab for neovascular AMD are similar to large prospective randomized trials.Eye (2009) 23, 1633–1640; doi:10.1038/eye.2009.175; published online 31 July 2009 [ABSTRACT FROM AUTHOR]
