Generating Evidence for Program Planning: Rapid Assessment of Avoidable Blindness in Bangladesh

ABSTRACTPurpose: There is a lack of data on the prevalence and causes of blindness in Bangladesh, which is important to plan effective eye health programs and advocate support services to achieve the goals of Vision 2020.Methods: We conducted a rapid assessment of avoidable blindness (RAAB) in 8 districts of Bangladesh (January 2010 – December 2012) to establish the prevalence and causes of blindness. People aged ≥50 years were selected, and eligible participants had visual acuity (VA) measured. Ocular examinations were performed in those with VA<6/18. Additional information was collected for those who had or had not undergone cataract surgery to understand service barriers and quality of service.Results: In total, 21,596 people were examined, of which 471 (2.2%, 95% confidence interval, CI, 2.0–2.4%) were blind. The primary cause of blindness was cataract (75.8%). The majority of blindness (86.2%) was avoidable. Cataract and refractive error were the primary causes of severe visual impairment (73.6%) and...
