Abstract
PURPOSE To evaluate the safety and efficacy of the Port Delivery System with ranibizumab (PDS) for the treatment of neovascular age-related macular degeneration (nAMD). DESIGN Phase 3, open-label, randomized, visual acuity assessor-masked noninferiority and equivalence trial. PARTICIPANTS Patients with nAMD diagnosed within 9 months of screening previously treated with and responsive to anti-vascular endothelial growth factor therapy. METHODS Patients were randomized 3:2 to treatment with the PDS with ranibizumab 100 mg/ml with fixed 24-week (Q24W) refill-exchanges (PDS Q24W) or intravitreal ranibizumab 0.5-mg injections every 4 weeks (monthly ranibizumab). MAIN OUTCOME MEASURES Primary end point was change in best-corrected visual acuity (BCVA) Early Treatment Diabetic Retinopathy Study letter (letters) score from baseline averaged over weeks 36 and 40 (noninferiority margin,-4.5 letters; equivalence margin, ±4.5 letters). RESULTS Archway enrolled 418 patients; 251 were randomized to and 248 received treatment with the PDS Q24W, and 167 were randomized to and received treatment with monthly ranibizumab. Baseline BCVA was 74.4 letters (PDS Q24W arm) and 75.5 letters (monthly ranibizumab arm; Snellen equivalent, 20/32). Adjusted mean change in BCVA score from baseline averaged over weeks 36 and 40 was +0.2 letters (standard error [SE], 0.5 letters) in the PDS Q24W arm and +0.5 letters (SE, 0.6 letters) in the monthly ranibizumab arm (difference, -0.3 letters; 95% confidence interval, -1.7 to 1.1 letters). PDS Q24W was both noninferior and equivalent to monthly ranibizumab. Of 246 PDS-treated patients assessed for supplemental ranibizumab treatment, 242 (98.4%) did not receive supplemental ranibizumab treatment before the first refill-exchange procedure, including 4 patients who discontinued treatment before the first refill-exchange procedure. Prespecified ocular adverse events of special interest were reported in 47 patients (19.0%) in the PDS Q24W arm and 10 patients (6.0%) in the monthly ranibizumab arm, which included, in the former arm, 4 (1.6%) endophthalmitis cases, 2 (0.8%) retinal detachments, 13 (5.2%) vitreous hemorrhages, 6 (2.4%) conjunctival erosions, and 5 (2.0%) conjunctival retractions. Most ocular adverse events in the PDS Q24W arm occurred within 1 month of implantation. CONCLUSIONS Archway met its primary objective and PDS Q24W demonstrated noninferior and equivalent efficacy to monthly ranibizumab, with 98.4% of PDS-treated patients not receiving supplemental treatment in the first 24-week interval.

Ophthalmology. 2021;(10):1448-1457
Abstract
PURPOSE To evaluate panretinal photocoagulation (PRP) treatment and re-treatment patterns in patients with diabetic retinopathy (DR) and diabetic macular edema (DME). DESIGN Post hoc analysis of the phase 3 RIDE (clinicaltrials.gov identifier, NCT00473382) and RISE (clinicaltrials.gov identifier, NCT00473330) clinical trials of ranibizumab for the treatment of DME. PARTICIPANTS Seven hundred fifty-nine patients were randomized for treatment. METHODS Panretinal photocoagulation treatment patterns and clinical experiences were assessed by baseline PRP treatment status. MAIN OUTCOME MEASURES Number and timing of on-study PRP treatment sessions undergone through month 24. Time to new proliferative event (composite end point) was also assessed. RESULTS At baseline, approximately 25% of patients in RIDE and RISE had undergone PRP treatment before enrollment (22.2%, 24.4%, and 25.4% of patients in the sham, ranibizumab 0.3 mg, and ranibizumab 0.5 mg arms, respectively). In patients without prior PRP at baseline (n = 577), 9.5% of sham-treated patients underwent 1 or more PRP treatments through month 24, compared with 1.1% and 1.6% of patients receiving ranibizumab 0.3 mg and ranibizumab 0.5 mg, respectively (P < 0.001 for both ranibizumab arms vs. sham). In patients with prior PRP at baseline (n = 182), 19.3% of sham-treated patients underwent 1 or more PRP treatments through month 24. No ranibizumab-treated patients with prior PRP at baseline required additional on-study PRP through month 24 (P < 0.001 for both ranibizumab arms vs. sham). Ranibizumab treatment also significantly reduced clinical DR progression among patients who underwent prior PRP. By month 24 in patients with prior PRP at baseline, the probability of experiencing a new proliferative event was 10.3% and 9.9% in patients receiving ranibizumab 0.3 mg and ranibizumab 0.5 mg treatment, respectively, compared with 39.4% in sham-treated patients (P < 0.0001). Overall, sham-treated patients, including those patients who were PRP naïve at baseline who went on to require PRP, experienced more clinical events than ranibizumab-treated patients. CONCLUSIONS In RIDE and RISE, PRP treatment was not a "1 and done" procedure, with on-study PRP re-treatment occurring in patients both with and without prior PRP treatment at baseline. Ranibizumab treatment reduced on-study PRP treatment and DR progression regardless of prior PRP treatment status at baseline.

Abstract
PURPOSE To assess the influence of baseline choroidal neovascularization (CNV) features on visual change and fluid resolution after anti-vascular endothelial growth factor (VEGF) treatment of eyes with neovascular age-related macular degeneration (nAMD). DESIGN Post hoc analysis of 52-week data from the phase 3 Vascular Endothelial Growth Factor VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet Age-Related Macular Degeneration (AMD) Studies (VIEW) 1 and 2 clinical trials. PARTICIPANTS One thousand eight hundred four patients with nAMD. METHODS Integrated data from VIEW 1 and 2 of 1804 eyes receiving intravitreal aflibercept injections (IAIs) 2 mg every 4 weeks, IAIs 2 mg every 8 weeks after 3 initial monthly doses, and ranibizumab every 4 weeks with documented baseline CNV type, total area, and leakage area were analyzed. Time to an event and cumulative incidence were evaluated by Kaplan-Meier analysis, and relative risks were estimated using proportional hazards analysis. MAIN OUTCOMES MEASURES Cumulative incidence of time to first sustained vision gain of 15 or more Early Treatment Diabetic Retinopathy Study letters, vision loss of more than 5 Early Treatment Diabetic Retinopathy Study letters from baseline, as well as first sustained absence of retinal fluid and intraretinal fluid as evaluated by OCT with respect to CNV type, total CNV, and leakage area. RESULTS Eyes with predominantly classic CNV (mean best-corrected visual acuity [BCVA], 48.2 letters at baseline) showed a higher incidence rate of first sustained gain of 15 letters or more than eyes with occult CNV (mean BCVA, 57.9 letters at baseline; P < 0.01). Eyes with occult CNV at baseline showed higher incidence rates of first sustained absence of retinal fluid and of intraretinal fluid than eyes with predominantly classic CNV (both P < 0.01). With increasing baseline CNV total area and leakage area, the incidence rate of first sustained gain of 15 letters or more decreased. CONCLUSIONS This post hoc analysis provided additional evidence for the role of baseline CNV features (CNV type, total area, and leakage area) in influencing visual and anatomic outcomes in eyes with nAMD after anti-VEGF treatment.

Abstract
BACKGROUND/PURPOSE Treating neovascular age-related macular degeneration with intravitreal aflibercept treat-and-extend (T&E) can reduce treatment burden. ARIES assessed whether intravitreal aflibercept early-start T&E was noninferior to late-start T&E. METHODS A randomized, open-label, Phase 3b/4 study that included treatment-naïve patients aged ≥50 years with the best-corrected visual acuity 73-25 Early Treatment Diabetic Retinopathy Study letters and active choroidal neovascularization secondary to AMD. Patients received 2 mg intravitreal aflibercept at Week (W) 0, W4, W8, and W16. At W16, patients were randomized 1:1 to early-start (2W interval adjustments) or late-start T&E (8W intervals until W48 then 2W interval adjustments). Primary endpoint: the best-corrected visual acuity change from randomization to W104. RESULTS Two-hundred seventy-one patients were randomized. The mean (SD) best-corrected visual acuity at baseline was 60.2 (12.1; early-T&E) and 61.3 (10.8; late-T&E) letters. The mean (SD) best-corrected visual acuity change (W16-104) was -2.1 (11.4) versus -0.4 (8.4) letters (early-T&E vs. late-T&E; least-squares mean difference: -2.0; 95% confidence interval: -4.75 to 0.71; P = 0.0162 for noninferior); +4.3 (13.4) versus +7.9 (11.9) letters (W0-104). The mean (SD) number of injections was 12.0 (2.3) versus 13.0 (1.8). From baseline to W104, 93.4% and 96.2% maintained best-corrected visual acuity; the mean (SD) central retinal thickness change was -161.6 (135.6) µm and -158.6 (125.1) µm. The last injection interval (W104) was ≥12W for 47.2% and 51.9% of patients. CONCLUSION Outcomes were similar between patients with neovascular age-related macular degeneration treated with an intravitreal aflibercept early-T&E or late-T&E regimen after initial dosing, with one injection difference over 2 years.

Abstract
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.

Abstract
PURPOSE To evaluate whether baseline demographic, clinical, and OCT characteristics predict visual acuity (VA) outcomes in patients receiving anti-vascular endothelial growth factor (VEGF) therapy for macular edema (ME) due to central retinal vein occlusion (CRVO). DESIGN Post hoc analysis of the randomized noninferiority trial (Lucentis, Eylea, Avastin in CRVO) LEAVO Study from December 12, 2014, to December 16, 2016, carried out across 44 UK National Health Service ophthalmology departments. PARTICIPANTS Data on 267 participants with a baseline best-corrected mean visual acuity (BCVA) range of 19 to 78 Early Treatment Diabetic Retinopathy Study letter score (approximate Snellen equivalent, 20/32 to 20/320) who had central subfield thickness (CST) ≥ 320 μm on Spectralis OCT (Heidelberg Engineering) were analyzed. METHODS Study participants were randomized to receive repeated intravitreal injections of ranibizumab (0.5 mg/50 μl), aflibercept (2.0 mg/50 μl), or bevacizumab (1.25 mg/50 μl), and a protocol-driven pro re nata re-treatment regimen at 4 to 8 weekly visits was followed up to week 100 after 4 mandated 4-weekly loading injections. MAIN OUTCOME MEASURES Change in BCVA and percentage of patients gaining ≥ 10 letters and achieving BCVA letter score > 70 letters at 52 and 100 weeks. RESULTS The analysis was adjusted for treatment effects and confirmed by sensitivity analysis. Age ≥ 75 years is a poor predictor for all 3 visual outcomes. Lower baseline BCVA predicted 10-letter gainers and higher gains in BCVA, although it is a poor predictor of achieving > 70 Early Treatment Diabetic Retinopathy Study letters. None of the baseline OCT morphologic characteristics except ellipsoid zone (EZ) integrity influenced any visual outcomes. Both baseline CST and total macular volume showed a nonlinear relation to 10-letter gainers, with CST > 900 μm being a poor prognostic indicator. Baseline CST and macular volume did not predict mean change in BCVA or BCVA > 70 letters at 52 and 100 weeks. The sensitivity analysis conclusions after removing iCRVO were similar. CONCLUSIONS At presentation, younger age, higher baseline BCVA, and a definitely intact subfoveal EZ are predictors of BCVA score > 70 letters at 100 weeks.

Abstract
PURPOSE To assess the noninferiority of the treat-and-extend (T&E) and fixed bimonthly regimens of 0.5 mg intravitreal ranibizumab as compared with the pro re nata (PRN) in naïve patients with neovascular age-related macular degeneration (nAMD). METHODS Phase IV, randomized, 12-month, multicentre trial. Patients aged ≥50 years with nAMD and visual impairment [best-corrected visual acuity (BCVA) between 23 and 78 Early Treatment Diabetic Retinopathy Study (ETDRS) letters] were eligible. Patients (one eye per patient) were randomized to bimonthly, n = 103, T&E, n = 99 or PRN, n = 104. Noninferiority was established at five letters ETDRS. RESULTS The mean (95% CI) difference in BCVA at 12 months was 7.2 (4.2-10.2), 6.4 (2.9-9.8), and 8.0 (51.1-11.0) in the bimonthly, T&E and PRN, respectively. The bimonthly or T&E regimens were not inferior to the PRN scheme. All regimens were associated with a significant reduction of central subfield thickness and volume. The mean (95% CI) number of injections in the bimonthly regimen (7.6, 7.5-7.7) was similar as compared with the PRN regimen (7.4, 6.7-8.0) (p = 0.159) but lower than in the T&E regimen (9.3, 8.9-9.7) (p < 0.001). CONCLUSION At 12 months, bimonthly and T&E ranibizumab were noninferior to PRN in naïve nAMD.

Abstract
PURPOSE To evaluate spectral-domain (SD)-OCT features associated with baseline vision and visual outcomes in the prospective, multicenter Study Evaluating Dosing Regimens for Treatment with Intravitreal Ranibizumab Injections in Subjects with Macular Edema following Retinal Vein Occlusion (SHORE). DESIGN Post hoc analysis of prospective clinical trial data. PARTICIPANTS Two hundred two participants in the 15-month, phase 4 SHORE study comparing monthly versus pro re nata ranibizumab after 7 monthly doses in eyes with retinal vein occlusion (RVO) with macular edema. METHODS Baseline SD-OCT images were assessed for (1) central subfield thickness (CST); (2) presence of vitreomacular adhesion, vitreomacular traction, or epiretinal membrane; (3) presence, location, and amount of intraretinal fluid or subretinal fluid (SRF); (4) presence, location, and amount of hyperreflective foci (HF); (5) disorganization of retinal inner layers (DRIL); and (6) disruption of external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ). Univariate and multivariate regression analyses were performed to evaluate the association of these features with baseline best-corrected visual acuity (BCVA) and change in BCVA after 7 monthly ranibizumab injections. MAIN OUTCOME MEASURES Association of SD-OCT features with baseline BCVA and change in BCVA after 7 monthly ranibizumab injections. RESULTS Before therapy, worse baseline BCVA was associated with ERM presence (P = 0.0045), thicker SRF (P = 0.0006), larger intraretinal cysts (P = 0.0015), and higher percentage of DRIL (P < 0.0001), percentage of ELM disruption (P < 0.0001), percentage of EZ disruption (P = 0.0003), and percentage of IZ disruption (P = 0.0018). In multivariate models, only percentage of ELM disruption independently impacted baseline BCVA (P < 0.0001). After 7 monthly ranibizumab injections, mean BCVA improved by 18.3±12.6 Early Treatment Diabetic Retinopathy Study letters in treated eyes. The only factors independently associated with BCVA gain after 7 monthly ranibizumab treatments were younger age (P < 0.0001) and worse baseline BCVA (P < 0.0001). CONCLUSIONS Although SD-OCT features may be associated with presenting vision in eyes with macular edema and RVO, most eyes treated with ranibizumab achieve substantial vision gains, and only older age and better baseline BCVA limited visual improvements.

Ophthalmic surgery, lasers & imaging retina. 2020;(4):210-218
Abstract
BACKGROUND AND OBJECTIVE To compare early and long-term visual responses to ranibizumab in patients with diabetic macular edema. PATIENTS AND METHODS Retrospective analysis of RIDE (NCT00473382) and RISE (NCT00473330). Vision outcomes over 36 months were compared between limited early gainers (gained ≤ 5 Early Treatment Diabetic Retinopathy Study [ETDRS] letters), early 1-line gainers (gained 6 to 9 ETDRS letters), and early 2-or-more-line gainers (gained ≥ 10 ETDRS letters) at Month 3. RESULTS Among 235 ranibizumab-treated patients, 42.6%, 20.0%, and 37.4% were limited early gainers, early 1-line gainers, and early 2-or-more-line gainers, respectively. At Month 36, 71.3% of limited early gainers achieved 6 to 9 and 10 or more ETDRS letter gains. Mean ETDRS letter scores at Month 36 were comparable between limited early gainers (67.8), early 1-line gainers (73.4), and early 2-or-more-line gainers (71.6). CONCLUSION Clinically meaningful vision outcomes were achieved with long-term ranibizumab treatment, irrespective of early visual acuity response.

Abstract
BACKGROUND/AIMS: To investigate the yearly change of real-world outcomes for best corrected visual acuity (BCVA) after 2-year clinical intervention for treatment-naïve diabetic macular oedema (DMO). METHODS Retrospective analysis of aggregated, longitudinal medical records obtained from 27 retina specialised institutions in Japan from Survey of Treatment for DMO database. A total of 2049 treatment-naïve centre involving DMO eyes of which the initial intervention started between 2010 and 2015, and had been followed for 2 years, were eligible. As interventions, antivascular endothelial growth factor (VEGF) agents, local corticosteroids, macular photocoagulation and vitrectomy were defined. In each eye, baseline and final BCVA, the number of each intervention for 2 years was extracted. Each eye was classified by starting year of interventional treatment. RESULTS Although baseline BCVA did not change by year, 2-year improvement of BCVA had been increased, and reached to +6.5 letters in the latest term. There is little difference among starting year about proportions of eyes which BCVA gained >15 letters, in contrast to those which lost >15 letters were decreased by year. The proportion of eyes receiving anti-VEGF therapy was dramatically increased, while those receiving the other therapies were gradually decreased. The proportion of eyes which maintained socially good vision of BCVA>20/40 has been increased and reached to 59.0% in the latest term. CONCLUSION For recent years, treatment patterns for DMO have been gradually but certainly changed; as a result, better visual gain, suppression of worsened eyes and better final BCVA have been obtained. Anti-VEGF therapy has become the first-line therapy and its injection frequency has been increasing.
