RESUMO
INTRODUCTION: Understanding patient perspectives of treatment may improve adherence and outcomes. This study explored real-world patient experiences with anti-vascular endothelial growth factor (anti-VEGF) treatment for diabetic macular edema (DME) and neovascular age-related macular degeneration (nAMD). METHODS: This multinational, non-interventional, quantitative, cross-sectional, observational survey assessed treatment barriers/burden, patient-reported visual functioning, and treatment satisfaction in DME and nAMD patients in the USA, the UK, Canada, France, Italy, and Spain. Treatment patterns and visual outcomes were extracted from medical charts. Regression models evaluated relationships between adherence, total missed visits, number of anti-VEGF injections, and clinical and patient-reported outcomes for visual functioning. Association between treatment satisfaction and aspects of burden were assessed. RESULTS: The survey was completed by 183 DME and 391 nAMD patients. Patients had moderately high vision-related functioning (25-item National Eye Institute Visual Functioning Questionnaire score: mean = 74.8) and were satisfied with their current treatment (mean total score: Macular Disease Treatment Satisfaction Questionnaire = 59.2; Retinopathy Treatment Satisfaction Questionnaire = 61.3). Treatment satisfaction scores were worse with higher time-related impacts of treatment (nAMD/DME), higher impacts on finances and daily life (nAMD), negative impacts on employment and lower expectations for treatment effectiveness (DME). Most patients reported ≥1 barrier (66.1% DME, 49.2% nAMD patients) related to treatment (35.0%), clinic (32.6%), and COVID-19 (21.1%). Moreover, 44.9% of patients reported some impairment in activities of daily living. Work absenteeism was observed among >60% of working patients. Nearly one-quarter (24.2%) of patients needed ≥1 day to recover from intravitreal injections; most reported ≥30 min of travel time (73.7%) and clinic wait time (54.2%). In unadjusted univariable analyses, treatment adherence (vs. nonadherence) was related to higher most recent visual acuity (ß = 8.98 letters; CI, 1.34-16.62) and lower odds of visual acuity below driving vision (≤69 letters) (OR = 0.50; CI, 0.25-1.00). CONCLUSION: More durable treatments with reduced frequency of injections/visits may reduce treatment burden and improve patient satisfaction, which may enhance adherence and visual outcomes.

BACKGROUND: Neovascular age-related macular degeneration (nAMD) has been treated with anti-vascular endothelial growth factor (anti-VEGF) therapy since 2006 with initial efficacy evidence of 2 years. In many, long-term therapy is required, and evidence for benefit is required from real-world data collection. METHODS: Retrospective review of electronic medical records of a consecutive series of patients treated with anti-VEGF therapy for nAMD over a 10-year period. Age, lens status and loss to follow-up was recorded. Primary outcome was change in VA at 10 years; secondary outcomes included proportion of eyes losing <15 letters at 3, 5, 7 and 10 years, number of injections and anatomic outcome. RESULTS: Of 196 patients (197 eyes), 90 patients had 10 years of follow-up data. Visual acuity (VA) declined by -11.2 letters (p=0.001), but 63.3% of eyes lost ≤15 letters. The proportion of eyes maintaining ≥70 letters was 17.7%, and the mean number of injections (±SD) was 47 ± 16. Retinal fluid was still present in 72.2% of eyes at 10 years. Forty-six percent of patients continued to receive anti-VEGF injections 10 years after treatment was commenced. CONCLUSION: Anti-VEGF treatment for nAMD over a ten-year period showed 63.3% of eyes lost ≤15 letters. Eyes with better baseline vision were more likely to continue receiving anti-VEGF treatment, but the frequency of injection treatment decreased.
RESUMO
PURPOSE: The purpose of this study was to investigate the visual and anatomic outcomes in patients with macular edema due to retinal vein occlusions (RVO) who were actively managed with intravitreal anti-vascular endothelial growth factor (VEGF) before and after cataract surgery. METHODS: Retrospective, cohort study of all patients with RVO who underwent cataract surgery and were receiving intravitreal anti-VEGF injections from January 1st, 2012 through October 31st, 2018. There were 31 eyes that underwent cataract surgery and received at least one intravitreal anti-VEGF injection for a diagnosis of RVO within 6 months prior to surgery. Data collected included the development of subretinal or intraretinal macular fluid in the 6 months following surgery, timing of injections, number of injections, best corrected visual acuity (BCVA), and central subfield thickness (CST). RESULTS: There was a significant improvement between pre- and post-operative BCVA when comparing all eyes (p values < .0001) and no significant difference in CST before and after surgery (p > .05). Eyes without fluid pre-operatively saw an improvement in visual acuity, but with an initial significant increase in CST (p = .03) that normalized over time (p = .33) without an increase in frequency of anti-VEGF injections. CONCLUSION: Patients with cataracts who are actively managed for macular edema due to RVO with anti-VEGF agents may undergo cataract surgery, knowing they will have a transient increase in macular thickness that resolves without adjusting the frequency of intravitreal injections and is not visually significant.

BACKGROUND: A new approach to address focal vitreomacular adhesion in patients with diabetic macular edema may control and stabilize diabetic macular edema with fewer anti-vascular endothelial growth factor injections. OBJECTIVES: The aim of this study was to demonstrate that diabetic macular edema can be improved by inducing the release of a vitreomacular adhesion, with less than 2500 µm, with enzymatic vitreolysis. METHODS: From a retrospective analysis of clinical records from patients with diabetic retinopathy, patients with diabetic macular edema and vitreomacular adhesion <2500 µm were selected for a single-arm prospective study. The primary endpoint was to control diabetic macular edema with fewer anti-vascular endothelial growth factor injections after an observed vitreomacular adhesion release. A statistical subanalysis was performed for the following two groups: the group with vitreomacular adhesion release (group 1) and the group without vitreomacular adhesion release (group 2). RESULTS: A total of 23 eyes from 19 patients were included. A reduction of the median number of injections was achieved in group 1 (p = 0.006). Adverse events were mild and transitory. CONCLUSION: Release of vitreomacular adhesion <2500 µm through enzymatic vitreolysis contributed to the control and stabilization of diabetic macular edema with fewer anti-vascular endothelial growth factor injections, reducing the burden and the risks related to these invasive and frequently chronic treatments.
