OBJECTIVES:

Intravitreal anti–vascular endothelial growth factor (VEGF) therapy is efficacious for neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME). However, the frequent treatment and monitoring required for optimal real-world outcomes can be burdensome to patients and can impact adherence to treatment. This study aimed to understand patient treatment experience with anti-VEGF standard of care.

METHODS:

A cross-sectional survey was employed comprising de novo questions, patient-reported outcome (PRO) measures and medical chart extraction. Adult patients with nAMD or DME treated with intravitreal anti-VEGF injections for ≥12 months were recruited via 38 clinical sites (6 Canada, 6 France, 4 Italy, 7 Spain, 6 United Kingdom, 9 United States).

RESULTS:

Surveys were completed by 391 patients with nAMD and 183 patients with DME. PRO scores indicated that patients across both conditions had relatively high vision-related functioning and were generally satisfied with their current treatment. Mean number of anti-VEGF injections over 12 months across countries ranged from 6.3–9.7 for nAMD and 4.3–8.0 for DME. Nineteen patients with nAMD (19/391; 5%) and 27 patients with DME (27/183; 15%) missed ≥1 injection or examination visit in the past 12 months. Reported barriers were mainly related to treatment (eg, pain and discomfort during/after anti-VEGF injection), clinic (eg, not having someone to accompany them to appointments) and, to a lesser extent, the COVID-19 pandemic. After treatment, the majority recovered in ≤1 day; however, 24% (139/574) needed >1 day to recover. Impairment in daily activities due to treatment was reported by 45% (258/574) of patients. Among working patients 62% (41/66) reported productivity impairment from absenteeism.

CONCLUSIONS:

Patients reported impairment of daily activities, burden and barriers related to intravitreal anti-VEGF therapy, despite high adherence and treatment satisfaction levels. More durable therapy options, requiring less frequent treatments may be able to reduce treatment-related burden and barriers.
