The Diabetic Retinopathy Barometer Study: Global perspectives on access to and experiences of diabetic retinopathy screening and treatment.

AIM: To assess the level of awareness, prevention and treatment of Diabetic Eye Disease (DED) comprising Diabetic Retinopathy (DR) and Diabetic Macula Edema (DME) retinopathy among adults with diabetes and health professionals. METHODS: The Diabetic Retinopathy Barometer Study consisted of a qualitative study, which consisted of semi-structured interviews, and a quantitative study using online surveys for adults with diabetes and for health professionals. RESULTS: A total of 4340 adults with diabetes and 2329 health professionals participated in the surveys. Diabetic eye disease (DED) without macular edema (DME) was reported by 19.5% of adults with diabetes and a further 7.6% reported that they had DME. Although 94% of adults with diabetes saw a health care professional for their diabetes, only 79% had ever had an eye examination for DED, and 23% had not had an eye examination in the last year. Moreover, 65% of the ophthalmologists surveyed reported that most patients presented when visual problems had already occurred. Overall, 62% of people with DED had received treatment. Of these, 74% had laser therapy, 29% surgery and 24% anti-VEGF therapy. CONCLUSION: Strategic investment is required to enhance patient education and professional training on the importance of regular eye examinations; and in providing accessible DR screening programmes and proactive treatments.
