VEGFA and Abnormal retinal morphology: In a Danish study, 73% of DME patients (n = 23) rated their health literacy as poor when surveyed with the European Health Literacy Survey Questionnaire (HLS-EU-Q47) [7, 14, 15].However, this questionnaire does not include explicit questions about retinal disease or anti-VEGF treatment, which was a major reason for developing true/false knowledge statements specifically for DME patients and their companions in our study.
