Abstract
PURPOSE To determine the association between central subfield thickness (CST) variability and visual outcomes in eyes with neovascular age-related macular degeneration treated with anti-vascular endothelial growth factor therapies. METHODS In this post hoc, treatment-agnostic analysis, patients (N = 1,752) were grouped into quartiles of increasing CST variation. The association between CST variability and best-corrected visual acuity was measured from baseline, or from the end of the loading phase, until the end of the study using a multilevel modeling for repeated-measures model. The association between CST variability and the presence of retinal fluid was also assessed. RESULTS Increased CST variability was associated with worse best-corrected visual acuity outcomes at the end of study, with a least-square mean difference in best-corrected visual acuity of 8.9 Early Treatment Diabetic Retinopathy Study letters between the quartiles with the lowest and highest CST variability at the final visit. Increased variability was also associated with a higher mean fraction of visits with the presence of fluid. CONCLUSION More stable CST was associated with better visual outcomes at the end of treatment suggesting that CST variability may provide a more reliable prognostic marker of visual outcomes than the presence of fluid alone, with the potential to enhance the clinical care of neovascular age-related macular degeneration patients.

Abstract
PURPOSE To describe longitudinal retinal fluid dynamics on spectral domain OCT and to identify imaging biomarkers that predict the worsening of DME with interval extension during anti-vascular endothelial growth factor (VEGF) therapy. DESIGN A post hoc sub-analysis of phase III, VISTA-DME study. METHODS Eyes received either intravitreal aflibercept injection 2 mg every 4 weeks (2q4) or every 8 weeks after 5 initial monthly injections (2q8), and eyes imaged with the Cirrus HD-OCT system were included. The macular cube was analyzed for 10 time-points from baseline through week 100. Retinal OCT images were evaluated using a novel software platform to extract retinal fluid features for calculation of volumetric fluid parameters, including the retinal fluid index (RFI): the percentage of retinal volume that was occupied by intraretinal fluid. RESULTS Fifty-five eyes were included in the 2q4 group, and 58 eyes were included in the 2q8 group. Early RFI volatility with a central macular RFI increase by ≥5 points from week 4 to 8 (P = .004, odds ratio [OR] 31.3, 95% confidence interval [CI] 3.0 to 329) and cumulative RFI volatility with an aggregate increase in macular RFI by ≥10 points from those timepoints with increased RFI between baseline to week 20, P = .005, OR 10.2, 95% CI 2.1 to 51.3) were both significant predictors for the worsening of DME and visual acuity when the treatment interval was extended to 8 weeks in the 2q8 group. CONCLUSIONS Early fluid dynamics as measured by (1) early RFI volatility and (2) cumulative RFI instability with aggregate increased RFI were associated with intolerance of interval extension.

Abstract
IMPORTANCE Visit adherence has been shown to play a significant role in patient health outcomes. The effect of missing visits on visual acuity (VA) in individuals with neovascular age-related macular degeneration has yet to be characterized. OBJECTIVE To quantify the association between patients' adherence to randomized clinical trial visits and VA in individuals with neovascular age-related macular degeneration based on 4 visit adherence metrics. DESIGN, SETTING, AND PARTICIPANTS This is a secondary analysis of the Comparison of Age-Related Macular Degeneration Treatment Trial randomized clinical trial. Individuals with age-related macular degeneration were recruited from 44 clinical centers in the United States between February 2008 and December 2009. The 2-year study protocol required 1 visit every 4 weeks (every 21-35 days for a total of 26 visits) for monthly vs pro re nata treatments of bevacizumab vs ranibizumab. Analysis took place from November 2018 through May 2019. EXPOSURES Visit adherence was measured in 4 ways: total number of missed visits, average number of days (avg days) between each visit, longest duration in days (max days) between visits, and visit constancy (the tally of 3-month periods with at least 1 visit attended). Average and max days were also categorized as on time (28-35 days), late (36-60 days), and very late (>60 days). MAIN OUTCOMES AND MEASURES Change in Early Treatment Diabetic Retinopathy Study VA between the baseline and the last visit. Linear multivariate regression models were applied to analyze the association between visit adherence and change in VA, controlling for age, sex, baseline VA, anti-vascular endothelial growth factor drug, number of injections, and dosing regimen. RESULTS Of 1178 patients, the mean (SD) age was 79.1 (7.3) years, and 727 (61.7%) were women. The mean (SD) number of missed visits was 2.4 (3.1). Overall, 1091 patients (92.6%) had complete visit constancy during the entire study period. Average days were categorized with 1060 patients (90.0%) classified as on time, 108 (9.2%) were late, and 10 (0.8%) were very late. For max days between visits, 197 patients (16.7%) were on time, 773 (65.6%) were late, and 208 (17.7%) were very late. After controlling for covariates, the late (avg days = -6.1; max days = -2.0) and very late (avg days = -12.5; max days = -5.9) groups saw fewer letters in both the avg and max days categories than patients in the on-time group (P < .001). CONCLUSIONS AND RELEVANCE These results provide evidence to support the concept that visit adherence contributes to VA outcomes in neovascular age-related macular degeneration. The magnitude of the association of visit adherence with VA outcomes in this clinical scenario suggests that substantial effort should be expended to strive for visit adherence or therapeutic strategies that reduce the visit burden without compromising VA outcomes.

Abstract
PURPOSE To compare visual outcomes and treatment burden between intravitreally administered aflibercept (IVT-AFL) and ranibizumab (RBZ) treat-and-extend (T&E) regimens in patients with wet age-related macular degeneration (wAMD) at 2 years. METHODS A systematic literature review was carried out in Medline, EMBASE, and CENTRAL in October 2018. Matching-adjusted indirect comparison (MAIC) and/or individual patient data meta-regression was used to connect ALTAIR (assessing IVT-AFL T&E) with other studies, adjusting for between-trial differences in baseline visual acuity and age or baseline visual acuity, age, and polypoidal choroidal vasculopathy (PCV) status. Sensitivity analyses were conducted to test the robustness of the results, including direct MAIC between IVT-AFL T&E (ALTAIR) and RBZ T&E (CANTREAT and TREX-AMD trials). RESULTS Six randomized controlled trials (RCTs) (ALTAIR, VIEW 1 and 2, CATT, CANTREAT, and TREX) were included in the analysis. IVT-AFL T&E was assessed in one study, ALTAIR (n = 255), while RBZ T&E was assessed in two trials (n = 327). At 2 years, the median difference (95% credibility interval) between IVT-AFL T&E and RBZ T&E regarding the numbers of Early Treatment Diabetic Retinopathy Study (ETDRS) letters gained was not significant (M1: - 2.29 [- 8.10, 3.58]; M2: - 0.55 [- 6.34, 5.29]). IVT-AFL T&E was associated with significantly fewer injections than RBZ-T&E (M1: - 6.12 [- 7.60, - 4.65]; M2: - 5.93 [- 7.42, - 4.45]). Results of the sensitivity analyses were consistent with the main scenarios. CONCLUSION Patients with wAMD receiving an IVT-AFL T&E regimen achieved and maintained improvement in visual acuity with fewer injections over 2 years compared with RBZ T&E. IVT-AFL T&E may therefore serve as the optimal therapy for wAMD, as it was associated with clinical efficacy and minimized treatment burden.

[Comparison of objective optical quality measured by double-pass aberrometry in patients with moderate dry eye: Normal saline vs. artificial tears: A pilot study].
Vandermeer, G, Chamy, Y, Pisella, PJ
Journal francais d'ophtalmologie. 2018;(3):238-245
Abstract
Dry eye is defined by a tear film instability resulting in variable but systematic fluctuations in the quality of vision. Variability in optical quality can be demonstrated using a double pass aberrometer such as the OQAS (Optical Quality Analyzing System, Visiometrics). The goal of this work is to compare fluctuations in objective quality of vision measured by OQAS between treatment with normal saline eye drops and treatment with carmellose 0.5% and hyaluronic acid 0.1% (Optive Fusion [OF], Allergan) in patients with moderate dry eye syndrome. Optical quality was measured by evaluating the variations in the Optical Scattering Index (OSI) over 20seconds using the OQAS. Inclusion criteria were dry eye syndrome with an Ocular Surface Disease Index (OSDI) score>23 treated only with artificial tears. The patients were their own controls: OF in one eye and normal saline in the fellow eye. The choice of the subject eye and control eye was determined in a randomized fashion. OSI variations were measured in each eye before instillation, 5minutes and 2hours after instillation. The primary endpoint was OSI fluctuation over 20seconds of measurement. Secondary endpoints were the number of blinks and patient's preference (preferred eye). Preliminary results were obtained on 19 patients. Average OSDI score was 36.8. Visual acuity was 10/10 with no significant difference between the two eyes. Prior to instillation, there was no significant difference between "normal saline" and "OF" eyes in terms of OSI, OSI variability or number of blinks. In the normal saline eye, there was no significant variation in mean OSI, OSI variability, OSI slope, or number of blinks. However, in the "OF" eye, there was a significant variation between initial and 2-hour OSI variability (0.363 versus 0.204; P<0.05), the average slope of OSI (0.04 versus 0.01; P<0.05) and the number of blinks (4.2 versus 2.8; P<0.05). Sixty-five percent of patients preferred the OF eye, 24% did not have a preference, and 11% preferred the normal saline eye. Objective quality of vision measured by OQAS is an interesting parameter for evaluating the effectiveness of a lacrimal substitute. The purpose of artificial tears is, among other things, to provide comfort and a reduction of dry eye symptoms such as poor quality of vision. This study demonstrates that 0.5% carmellose and 0.1% hyaluronic acid allowed better stabilization of the tear film and thus a significant improvement in the quality of vision compared to normal saline.

Abstract
BACKGROUND/AIMS: To evaluate intravitreal aflibercept versus laser in subgroups of patients with baseline Diabetic Retinopathy Severity Scale (DRSS) scores ≤43, 47, and ≥53 in VIVID-DME and VISTA-DME. METHODS Patients with diabetic macular oedema were randomised to receive intravitreal aflibercept 2 mg every 4 weeks (2q4), intravitreal aflibercept 2 mg every 8 weeks after five initial monthly doses (2q8), or macular laser photocoagulation at baseline with sham injections at every visit. These post hoc analyses evaluate outcomes based on baseline DRSS scores in patients in the integrated dataset. The 2q4 and 2q8 treatment groups were also pooled. RESULTS 748 patients had a baseline DRSS score based on fundus photographs (≤43, n=301; 47, n=153; ≥53, n=294). At week 100, the least squares mean difference between treatment groups (effect of intravitreal aflibercept above that of laser, adjusting for baseline best-corrected visual acuity) was 8.9 (95% CI 5.99 to 11.81), 9.7 (95% CI 5.54 to 13.91), and 11.0 (95% CI 7.96 to 14.1) letters in those with baseline DRSS scores ≤43, 47, and ≥53, respectively. The proportions of patients with ≥2 step DRSS score improvement were greater in the intravitreal aflibercept group versus laser, respectively, for those with baseline DRSS scores of ≤43 (13% vs 5.9%), 47 (25.8% vs 4.5%), and ≥53 (64.5% vs 28.4%). CONCLUSIONS Regardless of baseline DRSS score, functional outcomes were superior in intravitreal aflibercept-treated patients, demonstrating consistent treatment benefit across various baseline levels of retinopathy. TRIAL REGISTRATION NUMBERS NCT01331681 and NCT01363440, Post-results.

Abstract
PURPOSE Assess associations of 2-year visual acuity (VA) outcomes with VA and optical coherence tomography central subfield thickness (CST) after 12 weeks of anti-vascular endothelial growth factor treatment for diabetic macular edema in DRCR.net Protocol T. DESIGN Randomized clinical trial. METHODS Setting: Multicenter (89 U.S. sites). PATIENT POPULATION Eyes with VA and CST data from baseline and 12-week visits (616 of 660 eyes randomized [93.3%]). INTERVENTION Six monthly injections of 2.0 mg aflibercept, 1.25 mg bevacizumab, or 0.3 mg ranibizumab; subsequent injections and focal/grid laser as needed for stability. MAIN OUTCOME MEASURES Change in VA from baseline and VA letter score at 2 years. RESULTS Twelve-week VA response was associated with 2-year change in VA and 2-year VA letter score for each drug (P < .001) but with substantial individual variability (multivariable R2 = 0.38, 0.29, and 0.26 for 2-year change with aflibercept, bevacizumab, and ranibizumab, respectively). Among eyes with less than 5-letter gain at 12 weeks, the percentages of eyes gaining 10 or more letters from baseline at 2 years were 42% (20 of 48), 31% (21 of 68), and 47% (28 of 59), and median 2-year VA was 20/32, 20/32, and 20/25, in the aflibercept, bevacizumab, and ranibizumab groups, respectively. Twelve-week CST response was not strongly associated with 2-year outcomes. CONCLUSIONS A suboptimal response at 12 weeks did not preclude meaningful vision improvement (ie, ≥ 10-letter gain) in many eyes at 2 years. Eyes with less than 5-letter gain at 12 weeks often had good VA at 2 years without switching therapies.

Abstract
PURPOSE To identify baseline factors associated with change in visual acuity or development of vision-impairing central-involved diabetic macular edema (DME) over 2 years when treating proliferative diabetic retinopathy (PDR) with ranibizumab or panretinal photocoagulation (PRP). DESIGN Post hoc analyses of randomized, multicenter clinical trial data. PARTICIPANTS Eyes completing the 2-year visit (n = 328) or without vision-impairing central-involved DME at baseline (n = 302) in Diabetic Retinopathy Clinical Research Network Protocol S. METHODS Intravitreous ranibizumab (0.5 mg/0.05 ml) or PRP. MAIN OUTCOME MEASURES Change in visual acuity (area under the curve) and development of vision-impairing (20/32 or worse) central-involved DME over 2 years. RESULTS After multivariable model selection with adjustment for baseline visual acuity and central subfield thickness, no factors were identified as associated with change in visual acuity or development of vision-impairing central-involved DME within the ranibizumab group. In the PRP group, worse change in visual acuity was more likely with higher hemoglobin A1c level (-0.6 letters per 1% increase; 95% confidence interval [CI], -1.2 to -0.1 letters; continuous P = 0.03), more severe diabetic retinopathy (difference between high-risk PDR or worse vs. moderate PDR or better, -2.8 letters [95% CI, -5.5 to -0.2 letters]; continuous P = 0.003), and higher mean arterial pressure (difference between ≥100 mmHg vs. <100 mmHg, -2.0 letters [95% CI, -4.6 to 0.5 letters]; continuous P = 0.009). Development of vision-impairing central-involved DME was more likely with higher hemoglobin A1c level (hazard ratio [HR] per 1% increase, 1.31 [95% CI, 1.13-1.52]; continuous P < 0.001), more severe diabetic retinopathy (HR for high-risk PDR or worse vs. moderate PDR or better, 1.46 [95% CI, 0.73-2.92]; continuous P = 0.03), and the presence of cystoid abnormalities within 500 μm of the macula center (HR, 2.90 [95% CI, 1.35-6.24]; P = 0.006). CONCLUSIONS For eyes managed with PRP, higher hemoglobin A1c level and more severe diabetic retinopathy were associated with less vision improvement and an increased risk of vision-impairing central-involved DME developing. When managing PDR with ranibizumab, eyes gained vision, on average, with no baseline characteristics identified as associated with visual acuity or central-involved DME outcomes.

Abstract
IMPORTANCE The prevalence of persistent diabetic macular edema (DME) after months of anti-vascular endothelial growth factor therapy and its effect on visual acuity are unknown. OBJECTIVE To assess subsequent outcomes of eyes with DME persisting for 24 weeks after initiating treatment with 0.5 mg of ranibizumab. DESIGN, SETTING, AND PARTICIPANTS We performed post hoc, exploratory analyses of a randomized clinical trial from March 20, 2007, through January 29, 2014, from 117 of 296 eyes (39.5%) randomly assigned to receive ranibizumab with persistent DME (central subfield thickness ≥250 μm on time domain optical coherence tomography) through the 24-week visit. INTERVENTIONS Four monthly intravitreous injections of ranibizumab and then as needed per protocol. MAIN OUTCOMES AND MEASURES Cumulative 3-year probabilities of chronic persistent DME (failure to achieve a central subfield thickness <250 μm and at least a 10% reduction from the 24-week visit on at least 2 consecutive study visits) determined by life-table analyses, and at least 10 letter (≥2 line) gain or loss of visual acuity among those eyes. RESULTS The probability of chronic persistent DME among eyes with persistent DME at the 24-week visit decreased from 100% at the 32-week visit to 81.1% (99% CI, 69.6%-88.6%), 55.8% (99% CI, 42.9%-66.9%), and 40.1% (99% CI, 27.4%-52.4%) at the 1-, 2-, and 3-year visits, respectively. At 3 years, visual acuity improved in eyes with and without chronic persistent DME through the follow-up period, respectively, by a mean of 7 letters and 13 letters from baseline. Among 40 eyes with chronic persistent edema through 3 years, 17 (42.5%) (99% CI, 23.1%-63.7%) gained 10 letters or more from baseline, whereas 5 (12.5%) (99% CI, 2.8%-31.5%) lost 10 letters or more from baseline. CONCLUSIONS AND RELEVANCE These data suggest less than half of eyes treated for DME with intravitreous ranibizumab have persistent central-involved DME through 24 weeks after initiating treatment. Among the 40% that then have chronic persistent central-involved DME through 3 years, longer-term visual acuity outcomes appear to be slightly worse than in the 60% in which DME does not persist. Nevertheless, when following the treatment protocol used in this trial among eyes with vision impairment from DME, long-term improvement in visual acuity from baseline is typical and substantial (≥2-line) loss of visual acuity is likely uncommon through 3 years, even when central-involved DME chronically persists.

Abstract
PURPOSE To assess the incidence and progression of macular atrophy and other key anatomic outcomes over 7 to 8 years in an early cohort of ranibizumab-treated exudative age-related macular degeneration patients. DESIGN Follow-up analysis of long-term outcomes in a multicenter treatment cohort. METHODS Fourteen study sites enrolled 65 previous subjects from the ranibizumab treatment arms of the ANCHOR, MARINA, and HORIZON trials. In a single update visit, clinical assessment and retinal imaging studies were performed, with comparison with each subject's prior results from the previous trials. Early Treatment Diabetic Retinopathy Study visual acuity was the primary outcome. Secondary outcomes, including area of macular atrophy and selected anatomic factors, were analyzed for associations with long-term vision outcomes. RESULTS At a mean 7.3 years after ANCHOR or MARINA enrollment, mean visual acuity was 54 letters, study eyes having received a mean 1.6 injections per year since the HORIZON study. Macular atrophy was present in 98% of study eyes, the mean area increasing from 0.83 ± 0.96 mm(2) at the ANCHOR or MARINA year 2 exit to 2.22 ± 1.6 mm(2) at the SEVEN-UP visit, a growth rate of 0.28 mm(2)/year. Progression of macular atrophy was associated significantly with visual decline over this 5-year period (P < .001), and final macular atrophy lesion size was related significantly to final vision (P < .001). Other key anatomic outcomes (macular thickening, thinning, or fluid and submacular fibrosis) did not have significant effects on vision outcomes. CONCLUSIONS Seven years after initiation of intensive ranibizumab therapy for exudative age-related macular degeneration, macular atrophy progression and severity were the primary anatomic determinants of visual outcomes.
