Abstract
PURPOSE Ranibizumab monotherapy showed stronger effects on area of retinal neovascularization (NV) reduction while offering better visual acuity (VA) results than panretinal laser photocoagulation (PRP) monotherapy during the first 12 months of the PRIDE study. The second year of PRIDE was an observational, non-interventional follow-up, performed to evaluate long-term anatomical and functional outcomes in proliferative diabetic retinopathy (PDR) patients under real-life conditions, prior to the approval of ranibizumab for PDR. METHODS Seventy-three PDR patients (28 from the ranibizumab group; 20 from the PRP group; 25 from the combination group) were included in the observational follow-up phase and treated at the investigators discretion. Visual acuity (VA) measurements and retinal imaging were performed at Months 12, 18 and 24. RESULTS Mean (± SD) NV area in the ranibizumab monotherapy and combination follow-up groups increased from 3.16 ± 4.30 mm2 and 1.13 ± 2.78 mm2 at Month 12 to 6.09 ± 10.79 mm2 and 2.14 ± 4.41 mm2 at Month 18 and 10.00 ± 17.63 mm2 and 3.26 ± 7.05 mm2 at Month 24, respectively. In the PRP follow-up group, NV area declined from 5.44 ± 14.55 mm2 at Month 12 to 1.22 ± 1.67 mm2 at Month 18, but increased again to 4.05 ± 11.66 mm2 at Month 24. During the observational phase, only 2 (6;8) patients in the ranibizumab (PRP;combination) follow-up group were treated with anti-VEGF medications, while 17 (6;10) patients received PRP laser therapy. CONCLUSION Discontinuation of ranibizumab treatment in PDR patients may result in an increase of NV area and VA loss. Tight monitoring of disease activity and continued treatment beyond the first year is needed to maintain disease control.

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.

Abstract
PURPOSE To describe the sociodemographic, medical and management characteristics of patients using intravitreal (IVT) anti-vascular endothelial growth factors (VEGF) in France. METHODS An observational study was conducted in patients treated with IVT ranibizumab or aflibercept, aged 18 years or older using the French National Health Insurance Databases covering 99% of the French population. Patients currently treated in 2018 were included in a cross-sectional approach to describe treatment history over the previous 6 years. Patients newly treated between 2014 and 2018 were included in a longitudinal approach to describe treatment management during up to 6 years of follow-up. Sociodemographic characteristics and medical history were described in both populations. The analyses were performed at the patient level, as no distinction between the eyes could be made. RESULTS A total of 224 775 current users of IVT anti-VEGF in 2018 (mean age 78.1 ± 11.3 years, 60% female) and 330 969 new users between 2014 and 2018 (mean age 75.9 ± 12.0 years, 59% female) were included. In both populations cardiovascular comorbidities or risk factors were frequent and the main treatment indications were age-related macular degeneration and diabetic macular oedema. Among current users of IVT anti-VEGF in 2018, the mean number of years receiving a treatment was 2.9 ± 2.0 years, with a mean of 13.7 ± 11.8 dispensations. In the longitudinal approach, a 26% increase in IVT anti-VEGF initiation was observed between 2014 and 2018. For new users, the mean number of years receiving a treatment was 1.6 ± 1.6 and 67% had at least three dispensations within the first three months. A treatment interruption was observed for 83% of new users and occurred on average of 6.1 ± 8.1 months after initiation. The mean number of dispensations was 4.8 ± 2.8 in the first year and 2.2 ± 2.9 in the second year. The mean number of eye monitoring examinations was 6.5 ± 4.7 in the first year and 4.6 ± 4.4 in the second year. CONCLUSION This study described the real-world conditions of IVT anti-VEGF dispensing at the entire French population scale. Less frequent dispensations and surveillance examinations were observed than in monthly schemes applied in registration trials for IVT anti-VEGF. These results may indicate a lack of systematic monitoring associated with fewer injections and/or clinicians' preference for more flexible and personalized injection schemes than those originally recommended.

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 characterize the rates of panretinal photocoagulation (PRP) and anti-vascular endothelial growth factor (VEGF) medications before and after publication of the Diabetic Retinopathy Clinical Research Network protocol S. DESIGN A retrospective, cross-sectional study from January 2012, through September 2019, using a nationally representative claims-based database, Clinformatics Data Mart Database (OptumInsight, Eden Prairie, MN). PARTICIPANTS Eyes newly diagnosed with proliferative diabetic retinopathy (PDR), continuous enrollment, and no prior treatment with PRP or anti-VEGF agents. METHODS Interrupted time series regression analysis was performed to identify the annual change in treatment rates before and after the publication of Protocol S (November 2015). MAIN OUTCOME MEASURES Annual rates of anti-VEGF or PRP treatments per 1000 treated eyes with PDR. RESULTS From 2012 through 2019, 10 035 PRP or anti-VEGF treatments were administered to 3685 PDR eyes. Of these, 63.6% (n = 6379) were anti-VEGF agents, and 36.4% (n = 3656) were PRP treatments. Throughout treatment, 88.7% of eyes treated with anti-VEGF received the same agent and 7.7% were treated with both PRP and anti-VEGF agents. Panretinal photocoagulation rates declined from 784/1000 treated eyes in 2012 to 566/1000 in 2019 (pre-Protocol S: β = -32 vs. post-Protocol S: -77; P = 0.005), whereas anti-VEGF rates increased from 876/1000 in 2012 to 1583/1000 in 2019 (β = -48 vs. 161, respectively; P = 0.001). Panretinal photocoagulation rates in diabetic macular edema (DME) eyes did not significantly differ from 474/1000 in 2012 to 363/1000 in 2019 (β = -9 vs. -58 respectively; P = 0.091), and anti-VEGF rates increased from 1533/1000 in 2012 to 2096/1000 in 2019 (β = -57 vs. 187; P = 0.043). In eyes without DME, PRP use declined from 1017/1000 in 2012 to 707/1000 in 2019 (β = -31 vs. -111, respectively; P < 0.001), and anti-VEGF use increased from 383/1000 in 2012 to 1226/1000 in 2019 (β = -48 vs. 140, respectively; P < 0.001). CONCLUSIONS Following the publication of Protocol S, PRP rates decreased, while anti-VEGF rates increased. Panretinal photocoagulation rates did not significantly change among eyes with DME. Our findings indicate the impact that randomized controlled trials can have on real-world practice patterns.

Ophthalmology. Retina. 2021;(2):141-150
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
SIGNIFICANCE A differential outcome in randomized controlled trials of anti-vascular endothelial growth factor (anti-VEGF) therapy, including ranibizumab, for diabetic macular edema is a major dilemma for planning, optimizing, and managing clinical usage. The variable outcome of the therapeutics necessitates the importance of finding a predictive biomarker for anti-VEGF therapy to improve subject selection. PURPOSE Our study correlates the baseline pro- and anti-VEGF isoforms and its three receptors (VEGFReceptor1, VEGFReceptor2, and VEGFReceptor3) for circulatory candidate protein molecules among diabetic patients with macular edema, with the clinical outcome of ranibizumab therapy. METHODS This study included 86 individuals who were anti-VEGF naive at the time of ascertainment but have completed the standardized therapy regimen of the clinic. Plasma proteins for pro- and anti-VEGF isoforms and its three receptors were determined in replicate by an enzyme-linked immunosorbent assay. RESULTS The study demonstrated that 56 (65.12%) individuals benefited from the therapy in terms of letter gain (Snellen chart). Baseline plasma soluble VEGF receptor 2 (sVEGFR-2) was significantly higher among responders (65.10 pg/mL; 95% confidence interval, 55.41 to 74.80 pg/mL) compared with nonresponders (46.38 pg/mL; 95% confidence interval, 38.69 to 54.07 pg/mL; PFDR = .03). Diffuse diabetic macular edema with proliferative diabetic retinopathy increases the risk of nonresponse to the therapy by 3.03-fold (PFDR = .04). CONCLUSIONS The present study postulates that diffuse diabetic macular edema with proliferative diabetic retinopathy and baseline circulatory soluble VEGF receptor 2 may be potential candidates as therapy-stratifying markers for ranibizumab treatment among patients with diabetic macular edema.

Scientific reports. 2021;(1):23981
Abstract
This study aimed to analyze the concentrations of VEGF, b-FGF, TNF, interleukin (IL)-1, IL-6, IL-8, IL-10, and IL-12 in the aqueous humor of patients with diabetic macular edema with and without peripheral retinal ischemia and to ascertain the changes in the levels of these molecules during treatment with ranibizumab. A therapeutic, prospective, randomized interventional study was carried out. Twenty-four eyes from 24 patients were studied and divided into 3 groups. Group 1 (9 eyes) included patients with diabetic macular edema without peripheral ischemia. Group 2 (10 eyes) included patients with diabetic macular edema with peripheral ischemia. Group 3 (5 eyes), the control group, included patients without systemic and/or eye diseases. Patients in Groups 1 and 2 received 3 intravitreal injections of 2 mg/0.05 ml ranibizumab at an interval of approximately 30 days. Before administering the injections, the aqueous humor was collected. In the control group, aqueous humor was collected before facetectomy. During treatment, the median IL-6 concentration significantly increased in Group 1 but showed a slight but not significant decrease in Group 2. Interleukin 8 levels were significantly different at the end of treatment compared to the beginning in Groups 1 and 2. TNF, IL-1, IL-10, and IL-12 levels were practically unchanged in both groups. VEGF was significantly reduced at the end of the study in Groups 1 and 2. B-FGF was not detected in most of the studied patients, and in those with detectable levels, there was no significant variation. There was a significant increase in the median level of interleukin 6 in the group without ischemia and a significant decrease in VEGF in both groups. The cytokines TNF, IL-1, IL-10, and IL-12 did not show significant variation.

Erdem, B, Gok, M
Current eye research. 2021;(9):1387-1392
Abstract
Purpose: To investigate the effects of intravitreal ranibizumab (IVR) and intravitreal aflibercept (IVA) on systemic inflammatory and cardiovascular biomarkers in treatment-naive patients with neovascular age-related macular degeneration (nAMD)Methods: This study included 24 eyes of 24 patients treated with 0.5 mg ranibizumab (IVR group) and 25 eyes of 25 patients treated with 2.0 mg aflibercept (IVA group). Complete blood count, C-reactive protein (CRP), low-density lipoprotein cholesterol (LDL-c), high-density lipoprotein cholesterol (HDL-c), uric acid (UA), albumin, fibrinogen levels were measured in blood samples before and after the three-monthly loading dose treatment. Neutrophil/lymphocyte ratio (NLR), monocyte/HDL-c ratio (MHR), CRP/albumin ratio (CAR), monocyte/lymphocyte ratio (MLR), platelet/lymphocyte ratio (PLR) were also calculated.Results: A statistically significant decline was determined in post-treatment CRP (P = .002), LDL-c (P < .001) levels, white blood cell (WBC, P = .001), neutrophil (P < .001), monocyte (P = .019) counts and NLR (P = .020), MHR (P = .042), CAR (P = .010) ratios comparing with pre-treatment values in the IVA group. No statistically significant change was found in any of the parameters evaluated in the study in the IVR group. Also, there was no significant change in fibrinogen, lymphocyte count, MLR, HDL-c, UA, PLR, and platelet count values in both groups.Conclusion: Compared to IVR, IVA treatment had a small but significant effect on systemic inflammatory and cardiovascular biomarkers.
