Implementing a School Vision Screening Program in Botswana Using Smartphone Technology

Purpose: Child eye health is a significant public health issue in low- and middle-income countries, such as Botswana, and the need for eye care requires a well-integrated and innovative approach. Traditional vision screening tools are costly, difficult to transport, and reliant on highly trained eye care professionals. Novel smartphone-based vision screening technologies, however, are low cost, portable, and easily operated by trained novice users. Peek Vision is a mobile health (m-Health) organization that creates smartphone applications that screen for visual acuity, generate referrals to eye care professionals, and send phone notifications to those being screened. Methodology: In 2016, the government of Botswana partnered with local and international stakeholders to implement Peek vision screening in a subset of schoolchildren. From June to December of 2016, teachers, health assistants, nurses, and other volunteers in 49 schools in the Goodhope Subdistrict utilized Peek applications to screen schoolchildren, using acuity Results: Among 12,877 children screened, the application identified 16% (2,065/12,877) as screening positive for visual impairment, and these students were referred for optometric care. Ultimately, 96% (1,985/2,065) attended optometry triage camps, during which 42% (835/1,985) were provided with spectacles, 5% (94/1,985) received ophthalmic medications, and 3% (63/1,985) were referred for ophthalmic care. These findings underscore the need for comprehensive vision screening in schoolchildren in Botswana. Furthermore, the successful implementation of Peek smartphone applications illustrates the potential of m-Health technology for enacting comprehensive vision screening programs at a national level in Botswana and other similar countries.
