Objective: The Port Delivery System with ranibizumab (PDS) is approved in the United States for neovascular age-related macular degeneration (nAMD). Portal (NCT03683251) is evaluating long-term safety and tolerability of the PDS in patients with nAMD who completed the phase II Ladder (NCT02510794) or phase III Archway (NCT03677934) trials., Design: Multicenter, nonrandomized, open-label, extension clinical trial., Participants: All-PDS safety population (N = 555) comprises patients enrolled in Portal who completed Ladder or Archway. Because of data availability, efficacy population comprises Ladder-to-Portal patients only: patients who previously received PDS 10, 40, or 100 mg/mL pro re nata (as-needed [PRN]; n = 58, 62, and 59, respectively) or monthly intravitreal ranibizumab 0.5-mg injections (monthly ranibizumab; n = 41) in Ladder and subsequently enrolled in Portal., Methods: Ladder patients received PDS refill-exchanges PRN or monthly ranibizumab. Archway patients received PDS 100 mg/mL with fixed refill-exchanges every 24 weeks (Q24W) or monthly ranibizumab. Once enrolled in Portal, all patients receive PDS Q24W from day 1., Main Outcome Measures: Ocular adverse events of special interest (AESIs); changes from baseline in best-corrected visual acuity (BCVA) and center point thickness (CPT); supplemental ranibizumab treatment between refill-exchange procedures; and PDS Patient Preference Questionnaire results., Results: In the All-PDS safety population (mean follow-up, 111 weeks), 137 (24.7%) patients had ≥1 ocular AESI; most common were cataract (11.4%), vitreous hemorrhage (6.1%), and conjunctival thickening (bleb)/filtering bleb leak (6.3%). Endophthalmitis occurred in 11 of 555 (2.0%) patients. For Ladder-to-Portal patients previously treated with PDS 100 mg/mL or monthly ranibizumab, BCVA remained stable from baseline to month 48; mean (95% confidence interval) changes from baseline were 0.1 (-6.6 to 6.8; n = 31) and 2.3 (-9.4 to 14.1; n = 15) letters, respectively; CPT remained stable through month 48. Approximately 95% of patients did not need supplemental treatment before each refill-exchange for >2 years since Portal enrollment. Of Ladder-to-Portal previous monthly ranibizumab patients, 92% preferred the PDS over injections., Conclusions: Interim results from Portal suggest 4-year maintenance of visual/anatomic outcomes with PDS 100 mg/mL, with the PDS preferred to monthly injections. Long-term safety profile of the PDS is well characterized., 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 evaluate for the presence, severity, and type of exudation at each study visit for a subgroup of patients with neovascular age-related macular degeneration from the Archway and Portal trials., Design: Retrospective analysis of prospectively obtained data., Methods: Spectral-domain optical coherence tomography scans from each study visit of 44 patients from the Port Delivery System (PDS) arm and 32 patients from the monthly injection arm of Archway were evaluated, and composites of horizontal scans through the fovea were created. Each composite was graded for the presence, type, and severity of exudation and impact on best-corrected visual acuity., Results: After PDS implantation, 20 of 44 eyes (45%) never showed any exudation in the fovea, 2 (5%) never showed exudation in the fovea but had several missed visits, whereas 15 (34%), 3 (7%), and 4 (9%) showed mild, moderate, or severe exudation at 1 or more study visits, respectively. When exudation was present, it was most commonly subretinal fluid (50%). Of 32 patients randomized to monthly injections, 15 (47%) had no exudation in the fovea during monthly injections or after PDS implantation. Fluctuation of exudation in the fovea over time was seen in some patients after PDS implantation or during monthly injections with little or no identifiable impact on best-corrected visual acuity. In the 7 eyes with moderate or severe exudation in the fovea after PDS implantation, final vision was good in 5 (20/25 in 3, 20/40 in 1, and 20/50 in 1) and 2 had reduced vision from submacular hemorrhage., Conclusions: The PDS provides excellent control of exudation in the fovea in patients with neovascular age-related macular degeneration, and when exudation occurs, it often resolves without a negative impact on vision., (Copyright © 2023 The Authors.

Purpose: To report 2-year results from the Archway clinical trial of the Port Delivery System with ranibizumab (PDS) for treatment of neovascular age-related macular degeneration (nAMD)., Design: Phase 3, randomized, multicenter, open-label, active-comparator-controlled trial., Participants: Patients with previously treated nAMD diagnosed within 9 months of screening and responsive to anti-vascular endothelial growth factor therapy., Methods: Patients were randomized 3:2 to PDS with ranibizumab 100 mg/ml with fixed refill-exchanges every 24 weeks (PDS Q24W) or intravitreal ranibizumab 0.5 mg injections every 4 weeks (monthly ranibizumab). Patients were followed through 4 complete refill-exchange intervals (∼2 years)., Main Outcome Measures: Change in best-corrected visual acuity (BCVA) Early Treatment Diabetic Retinopathy Study (ETDRS) letter score from baseline averaged over weeks 44 and 48, weeks 60 and 64, and weeks 88 and 92 (noninferiority margin, -3.9 ETDRS letters)., Results: The PDS Q24W was noninferior to monthly ranibizumab, with differences in adjusted mean change in BCVA score from baseline averaged over weeks 44/48, 60/64 and 88/92 of -0.2 (95% confidence interval [CI], -1.8 to +1.3), +0.4 (95% CI, -1.4 to +2.1) and -0.6 ETDRS letters (95% CI, -2.5 to +1.3), respectively. Anatomic outcomes were generally comparable between arms through week 96. Through each of 4 PDS refill-exchange intervals, 98.4%, 94.6%, 94.8%, and 94.7% of PDS Q24W patients assessed did not receive supplemental ranibizumab treatment. The PDS ocular safety profile was generally unchanged from primary analysis. Prespecified ocular adverse events of special interest (AESI) were reported in 59 (23.8%) PDS and 17 (10.2%) monthly ranibizumab patients. The most common AESI reported in both arms was cataract (PDS Q24W, 22 [8.9%]; monthly ranibizumab, 10 [6.0%]). Events in the PDS Q24W arm included (patient incidence) 10 (4.0%) conjunctival erosions, 6 (2.4%) conjunctival retractions, 4 (1.6%) endophthalmitis cases, and 4 (1.6%) implant dislocations. Serum ranibizumab sampling showed that the PDS continuously released ranibizumab over the 24-week refill-exchange interval and ranibizumab serum concentrations were within the range experienced with monthly ranibizumab., Conclusions: The PDS Q24W showed noninferior efficacy to monthly ranibizumab through approximately 2 years, with approximately 95% of PDS Q24W patients not receiving supplemental ranibizumab treatment in each refill-exchange interval. The AESIs were generally manageable, with learnings continually implemented to minimize PDS-related AEs., Financial Disclosure(s): Proprietary or commercial disclosure may be found after the references., (Copyright © 2023 American Academy of Ophthalmology.

Purpose: To evaluate the relationship between retinal fluid location, amount/severity, and vision with ranibizumab-treated neovascular age-related macular degeneration (nAMD)., Methods: In the phase 3 HARBOR trial (NCT00891735), treatment-naive patients with nAMD received ranibizumab 0.5 or 2.0 mg through month 24. This post hoc analysis included eyes with subretinal fluid (SRF) and/or intraretinal fluid (IRF) at screening, baseline, or week 1, and optical coherence tomography data at months 12 and 24 (n = 917). Outcomes were best-corrected visual acuity (BCVA) change from baseline and proportion of eyes with 20/40 or better vision at months 12 and 24. Eyes were stratified by the location, amount, and/or severity of fluid., Results: At baseline, 86% and 63% of eyes had SRF and IRF, respectively. Among eyes with residual SRF, mean BCVA gains at each time point were greater in eyes with central versus noncentral SRF; location did not affect the odds of having 20/40 or better vision over 24 months. Eyes with 20/40 or better BCVA at month 12 had significantly lower SRF thickness versus eyes with worse vision; however, no difference was apparent at month 24. Vision was comparatively worse in eyes with residual IRF at months 12 and 24; location and severity did not appear to affect this outcome., Conclusion: Residual IRF was associated with worse vision outcomes, regardless of location/severity, whereas, despite continued treatment, residual SRF was not associated with worse vision outcome at 24 months, regardless of location/thickness. These data suggest complex relationships between residual fluid, severity, and vision., (© 2022. The Author(s).)

Importance: The port delivery system (PDS) with ranibizumab has demonstrated noninferior and equivalent efficacy compared with monthly intravitreal injections of ranibizumab, an anti-vascular endothelial growth factor (VEGF) agent, in patients with neovascular age-related macular degeneration (nAMD), but evaluating patient preference is important to help inform clinical decision-making., Objective: Evaluate treatment satisfaction for ranibizumab delivered via PDS vs intravitreal injections as well as patient preference among those assigned to PDS., Design, Setting, and Participants: Archway was a phase 3 randomized active-comparator open-label clinical trial conducted at 78 sites in the US. Patients 50 years and older with nAMD diagnosed within 9 months of screening with a documented response to anti-VEGF therapy were included. Of 619 patients screened, 418 were enrolled; 415 were included in the primary analysis and 234 were included in the secondary exploratory analysis. The Archway study ran from September 12, 2019, through primary readout on May 22, 2020., Interventions: Patients were randomized 3:2 to PDS with ranibizumab, 100 mg/mL, with fixed refill exchanges every 24 weeks or intravitreal ranibizumab injections, 0.5 mg, every 4 weeks., Main Outcomes and Measures: Treatment satisfaction was measured using the Macular Disease Treatment Satisfaction Questionnaire in the PDS and intravitreal injection arms at week 40. Patient preference was assessed using the content-validated PDS Patient Preference Questionnaire (PPPQ), which measured the proportion of patients in the PDS arm with monthly monitoring who preferred treatment with the PDS at week 40 over previous intravitreal injections or concurrent fellow-eye injections. Both outcomes were exploratory end points., Results: The mean (SD) age of participants at baseline was 75.0 (7.9) years; 234 participants (59%) were women and 162 (41%) were men. At week 40, differences in overall treatment satisfaction scores were minimal for the PDS and intravitreal injection arms (mean, 68.0; 95% CI, 67.4-68.6; n = 237 and mean, 66.1; 95% CI, 64.9-67.3; n = 159, respectively; difference, 1.9; 95% CI, 0.7-3.1). A total of 234 of 248 patients (94.4%) in the PDS arm were included in the PPPQ analysis. At week 40, almost all patients in the PDS arm preferred treatment via PDS (218 of 234 [93.2%]) vs previous intravitreal injections (3 of 234 [1.3%]), including 172 of 234 (73.5%) with a very strong preference for the PDS. In patients who received concurrent fellow-eye injections (n = 78), 72 (92.3%) preferred the PDS., Conclusions and Relevance: Although PDS treatment was preferred by almost all patients assigned to PDS over previous intravitreal injections, both delivery methods have high treatment satisfaction. These findings provide further evidence for the PDS as a meaningful alternative treatment option for patients with nAMD., Trial Registration: ClinicalTrials.gov Identifier: NCT03677934.

Purpose: To characterize relationships between Consensus on Neovascular Age-Related Macular Degeneration Nomenclature (CONAN) Study Group classifications of macular neovascularization (MNV) and visual responses to ranibizumab in patients with neovascular age-related macular degeneration (nAMD)., Methods: This was a post hoc analysis of the phase 3 HARBOR trial of ranibizumab in nAMD. Analyses included ranibizumab-treated eyes with baseline multimodal imaging data; baseline MNV; subretinal and/or intraretinal fluid at screening, baseline, or week 1; and spectral-domain optical coherence tomography images through month 24 (n = 700). Mean best-corrected visual acuity (BCVA) over time and mean BCVA change at months 12 and 24 were compared between eyes with type 1, type 2/mixed type 1 and 2 (type 2/M), and any type 3 MNV at baseline., Results: At baseline, 263 (37.6%), 287 (41.0%), and 150 (21.4%) eyes had type 1, type 2/M, and any type 3 lesions, respectively. Type 1 eyes had the best mean BCVA at baseline (59.0 [95% CI: 57.7-60.3] letters) and month 24 (67.7 [65.8-69.6] letters), whereas type 2/M eyes had the worst (50.0 [48.6-51.4] letters and 60.8 [58.7-62.9] letters, respectively). Mean BCVA gains at month 24 were most pronounced for type 2/M eyes (10.8 [8.9-12.7] letters) and similar for type 1 (8.7 [6.9-10.5] letters) and any type 3 eyes (8.3 [6.3-10.3] letters)., Conclusion: Differences in BCVA outcomes between CONAN lesion type subgroups support the use of an anatomic classification system to characterize MNV and prognosticate visual responses to anti-vascular endothelial growth factor therapy for nAMD., Trial Registration: ClinicalTrials.gov identifier: NCT00891735.

Purpose: To investigate the relationship between retinal fluid and vision in ranibizumab-treated patients with neovascular age-related macular degeneration (nAMD)., Design: Clinical cohort study using post hoc analysis of clinical trial data., Methods: We assessed data from HARBOR (NCT00891735), a phase III, randomized, controlled trial. We reviewed 917 patients ≥50 years of age with subfoveal nAMD associated with subretinal (SRF) and/or intraretinal fluid (IRF) at baseline, screening, or week 1. The intervention was intravitreal ranibizumab 0.5 or 2.0 mg (all treatment arms pooled). Outcomes included mean best-corrected visual acuity (BCVA) and BCVA change from baseline at months (M) 12 and 24 evaluated by the presence/absence of SRF and/or IRF., Results: Baseline BCVA was higher with residual vs resolved SRF at M12 (mean [95% confidence interval {CI}] 58.8 letters [57.2-60.4] vs 53.5 [52.4-54.5]) and M24 (59.3 letters [57.8-60.8] vs 53.5 [52.5-54.5]). Mean BCVA change (adjusted for baseline) to M12 was greater with residual vs resolved SRF (mean difference [95% CI], +2.4 letters [+0.1 to +4.7]), but lower with residual vs resolved IRF (-3.5 letters [-5.8 to -1.2]). Eyes with residual SRF (no IRF) exhibited the largest mean BCVA gains (M12, +14.1 letters; M24, +13.2 letters), followed by resolved SRF/IRF (M12, +10.6 letters; M24, +10.0 letters), residual SRF/IRF (M12, +7.2 letters; M24, +8.5 letters), and residual IRF only (M12, +5.5 letters; M24, +3.6 letters)., Conclusions: Vision outcomes (adjusted for baseline BCVA) through M24 were better in ranibizumab-treated eyes with residual vs resolved SRF, and worse with residual vs resolved IRF. Presence of residual retinal fluid requires a more complex and nuanced assessment and interpretation in the context of nAMD management., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Purpose: To report the end-of-study results from the Ladder clinical trial of the Port Delivery System with ranibizumab (PDS) for the treatment of neovascular age-related macular degeneration (nAMD)., Design: Multicenter, randomized, active treatment-controlled phase 2 clinical trial., Participants: Patients diagnosed with nAMD with a documented response to anti-vascular endothelial growth factor treatment who received study treatment (N = 220)., Methods: Patients were randomized 3:3:3:2 to treatment with the PDS filled with ranibizumab 10-mg/ml, 40-mg/ml, and 100-mg/ml formulations or monthly intravitreal ranibizumab 0.5-mg injections., Main Outcome Measures: End-of-study results for the time to first meeting refill criteria (first refill), mean change from baseline for best-corrected visual acuity (BCVA) and central foveal thickness (CFT), and safety., Results: At study end, the mean time on study was 22.1 months (range, 10.8-37.6 months) for all PDS patients. Median time to first refill was 8.7 months, 13.0 months, and 15.8 months, and 28.9%, 56.0%, and 59.4% of patients went 12 months or longer without meeting refill criteria in the PDS 10-mg/ml, 40-mg/ml, and 100-mg/ml treatment arms, respectively. At month 22, the observed mean BCVA change from baseline was ‒4.6 Early Treatment Diabetic Retinopathy Study (ETDRS) letters, ‒2.3 ETDRS letters, +2.9 ETDRS letters, and +2.7 ETDRS letters in the PDS 10-mg/ml, 40-mg/ml, 100-mg/ml, and monthly intravitreal ranibizumab 0.5-mg treatment arms, respectively. At month 22, the observed mean CFT change from baseline was similar in the PDS 100-mg/ml and monthly intravitreal ranibizumab 0.5-mg treatment arms. No new safety signals were detected during the additional follow-up., Conclusions: Over a mean of 22 months on study, vision and anatomic outcomes were comparable between the PDS 100-mg/ml and monthly intravitreal ranibizumab 0.5-mg arms, with a lower total number of ranibizumab treatments with the PDS. The Ladder end-of-study findings were consistent with the primary analysis, and the PDS generally was well tolerated throughout the entire study period. The PDS has the potential to reduce treatment burden in patients with nAMD while maintaining vision., (Copyright © 2020 American Academy of Ophthalmology. Published by Elsevier Inc.

Purpose: To evaluate the agreement between detection of activity of choroidal neovascularization (CNV) in neovascular age-related macular degeneration (AMD) by fundus fluorescein angiography (FFA) and spectral-domain (SD) OCT in the HARBOR study. Most retina specialists rely on OCT to guide treatment decisions in neovascular AMD. However, OCT may not always detect exudative activity. Traditionally, FFA was frequently performed in clinical practice, but its use has diminished due to reliance on OCT., Design: Retrospective post hoc analysis of prospective clinical trial (HARBOR; ClinicalTrials.gov identifier, NCT00891735)., Participants: Patients with neovascular AMD in the HARBOR Trial., Methods: Baseline to month 24 data from all randomized study eyes in HARBOR with both FFA and SD OCT data were analyzed for (1) evidence of CNV activity on SD OCT (presence of subretinal fluid, intraretinal fluid, and/or cystoid spaces); (2) evidence of CNV activity on FFA identified by the presence of leakage, and (3) cross-tabulation of CNV activity identified by FFA and SD OCT by office visit., Main Outcome Measures: The percent agreement between FFA and SD OCT in detecting CNV activity and sensitivity and specificity of SD OCT to detect fluorescein leakage in neovascular AMD using FFA as the reference standard., Results: At baseline, 1094 patients (99.9%) had agreement between SD OCT and FFA in detecting CNV activity. By month 24, of the 779 total active cases, the agreement was only 36% (277 cases). By month 24, most cases (n = 452 [58%]) had evidence of CNV activity on SD OCT only, whereas 6% of cases (n = 50) had CNV activity identified by FFA only. At screening and months 3, 6, 12, and 24, 92% to 100% of cases identified by FFA only were occult CNV lesions. Using FFA as the reference standard, the sensitivity and specificity of SD OCT in detecting CNV activity was 91% (95% confidence interval [CI], 84%-99%) and 13% (95% CI, 4%-22%)., Conclusions: Spectral-domain OCT alone can be relied upon for detecting CNV activity while monitoring eyes with neovascular AMD. However, FFA may still be of value in those with occult lesions that appear quiescent on SD OCT, as this type of lesion may show leakage on FFA., (Copyright © 2020 American Academy of Ophthalmology.

Purpose: To identify baseline risk factors for macular atrophy (MA) development in HARBOR via a longitudinal assessment of monthly spectral-domain (SD)-OCT scans. Previous analyses of MA in HARBOR examined data from color fundus photography (CFP) and fluorescein angiography (FA)., Design: Retrospective, post hoc analysis of SD-OCT images from HARBOR (ClinicalTrials.gov identifier, NCT00891735), a phase 3, multicenter, prospective, randomized, double-blind, active treatment-controlled clinical trial., Participants: Patients (N = 1097) with subfoveal choroidal neovascularization secondary to neovascular age-related macular degeneration (nAMD) treated with intravitreal ranibizumab 0.5 mg monthly (n = 275), 0.5 mg pro re nata (PRN) after 3 loading doses (n = 275), 2.0 mg monthly (n = 274), or 2.0 mg PRN (n = 273)., Methods: Evaluable SD-OCT macular cube scans from patients with 24 months of follow-up (N = 941) were examined monthly from baseline to month 24 by masked reading center-trained graders. Atrophy diagnosis criteria were consistent with those proposed by the Classification of Atrophy Meetings (CAM) group: hypertransmission of light into the choroid, loss of retinal pigment epithelium, and loss of outer retinal layers. Multivariable proportional hazards regression was performed for time to atrophy development., Main Outcome Measures: Risk factors for MA as determined by time to MA development over 24 months of treatment., Results: Baseline risk factors for MA were confirmed from prior analyses that used CFP and FA data: absence of subretinal fluid, presence of intraretinal cysts, presence of Type 3 neovascularization, and presence of atrophy in the fellow eye. This analysis of SD-OCT data identified new baseline risk factors for MA: higher central drusen volume, lower choroidal thickness, presence of nascent atrophy, presence of reticular pseudodrusen, and increased central foveal thickness. Ranibizumab treatment regimen and dose level were not found to be risk factors for MA development., Conclusions: In this analysis of a major nAMD trial using CAM atrophy criteria, new baseline risk factors for MA development were identified using an SD-OCT dataset. Risk factors for MA development identified by prior analyses were confirmed. Monthly treatment with ranibizumab 0.5 mg was not found to be a risk factor for MA development over 24 months., (Copyright © 2020 American Academy of Ophthalmology. Published by Elsevier Inc.

Purpose: Previous studies of macular atrophy (MA) in HARBOR analyzed color fundus photography and fluorescein angiography image data. This study performed a longitudinal assessment of monthly spectral-domain (SD) OCT scans to determine MA prevalence, incidence, and progression in HARBOR., Design: Post hoc analysis of SD OCT images from HARBOR (ClincalTrials.gov identifier, NCT00891735), a phase 3 multicenter, prospective, randomized, double-blind, active treatment-controlled clinical trial., Participants: Patients (n = 1097) with subfoveal choroidal neovascularization secondary to neovascular age-related macular degeneration (nAMD) treated with ranibizumab 0.5 mg monthly (n = 275), 0.5 mg pro re nata (PRN) after 3 loading doses (n = 275), 2.0 mg monthly (n = 274), or 2.0 mg PRN (n = 273)., Methods: Evaluable SD OCT macular cube scans from patients with 24 months of follow-up (N = 941) were examined by masked reading center-trained graders monthly from baseline to month 24. Atrophy diagnosis criteria were consistent with those proposed by the Classification of Atrophy Meetings (CAM) group: hypertransmission of light into the choroid, retinal pigment epithelium loss, and loss of outer retinal layers. Macular atrophy was considered Definite if all 3 criteria were met and Questionable if 2 were met. Study arms were compared for time to MA detection (log-rank test) and enlargement rates (time × arm interaction test)., Main Outcome Measures: Prevalence, incidence, and enlargement rates of MA., Results: At baseline, imbalance in MA rates across ranibizumab arms was evident (0.5 mg monthly, 19.1%; 0.5 mg PRN, 16.1%; 2.0 mg monthly, 10.1%; 2.0 mg PRN, 10.5%). At month 24, new MA development rates in eyes without baseline MA were similar between ranibizumab doses (0.5 mg, 25.9%; 2.0 mg, 25.4%) and treatment regimens (monthly, 26.4%; PRN, 25.0%). No significant differences in enlargement rate of new atrophy area (P = 0.479, square-root transformed) or time to detection of new MA (P = 0.997) were evident among study arms., Conclusions: In this analysis of a major nAMD trial using CAM atrophy criteria, no differences were observed in incidence or progression rates of new MA among study arms, ranibizumab doses, or treatment regimens. Monthly versus PRN treatment did not influence MA incidence or progression., (Copyright © 2019 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.)

Purpose: To determine optical coherence tomography signs associated with macular atrophy (MA) in eyes with neovascular age-related macular degeneration and pigment epithelial detachments treated with vascular endothelial growth factor inhibitors., Methods: Optical coherence tomography scans from a subgroup of the pigment epithelial detachment cohort of the HARBOR study were analyzed for MA. Two groups were formed based on MA presence/absence at Month 24. Then, optical coherence tomography scans from each baseline visit were graded with standard reading center grading parameters including ellipsoid zone disruption, intraretinal cysts, subretinal fluid, and MA or nascent MA in the study and fellow eyes., Results: Twenty-eight eyes from 28 patients were included in the analysis. Fourteen eyes had optical coherence tomography-based MA at Month 24 and 14 did not. Macular atrophy at Month 24 was significantly associated with 1) MA/nascent MA at baseline (P = 0.0136), 2) intraretinal cysts at baseline (P = 0.0048), and 3) collapse of pigment epithelial detachments in the study eye (P = 0.0025). Macular atrophy was not associated with ellipsoid zone disruption or subretinal fluid in the study eye at baseline., Conclusion: This study suggests that some optical coherence tomography findings in eyes of patients with neovascular age-related macular degeneration were present before the start of anti-vascular endothelial growth factor therapy and may predict the development of MA.

Purpose: To analyze the effect of baseline presence and height of pigment epithelial detachments (PEDs) on visual and anatomic outcomes at 24 months in patients with neovascular age-related macular degeneration (AMD) treated with ranibizumab., Design: Post hoc analysis of HARBOR, a 24-month, phase III, randomized, multicenter, double-masked, active treatment-controlled study (clinicaltrials.gov identifier, NCT00891735)., Participants: One thousand ninety-seven patients with neovascular AMD., Methods: Intravitreal ranibizumab 0.5 mg or 2.0 mg monthly or pro re nata (PRN) after 3 monthly loading doses., Main Outcome Measures: We evaluated the effect of presence and height of baseline PED on several outcomes at 24 months, including best-corrected visual acuity (BCVA), change in PED height, resolution of PED, and number of injections in the PRN arms. Development of macular atrophy at month 24 by presence or absence of PED was evaluated., Results: Five hundred ninety-eight (54.5%) patients showed PED at baseline. In the ranibizumab 0.5-mg PRN group, mean numbers of injections were similar for patients with PED present or absent at baseline (14.0 vs. 12.5). Mean BCVA gains from baseline to 24 months were seen in all treatment groups and were comparable in patients with or without PED at baseline treated with ranibizumab 0.5 mg monthly (PED present at baseline, +9.0 letters; PED absent at baseline, +11.3 letters), 0.5 mg PRN (present, +8.4; absent, +7.9), 2.0 mg monthly (present, +7.1; absent, +11.1), or 2.0 mg PRN (present, +7.2; absent, +8.8). When analyzed by baseline PED height, mean BCVA gains were demonstrated and comparable in all treatment groups at 24 months except for patients treated with ranibizumab 2.0 mg monthly in the extra-large group (PEDs ≥352 μm; mean BCVA change, -0.8 letters). At 24 months, 53.2% (0.5 mg monthly), 44.5% (0.5 mg PRN), 70.4% (2.0 mg monthly), and 57.3% (2.0 mg PRN) of patients showed complete resolution of PED., Conclusions: Ranibizumab 0.5 mg given monthly or PRN effectively treated PEDs in patients with neovascular AMD, and significant vision gains resulted regardless of PED status and height at baseline. In this analysis, there was no additional vision benefit with a higher dose of ranibizumab (2.0 mg)., (Copyright © 2016 American Academy of Ophthalmology. Published by Elsevier Inc.
