Village-Integrated Eye Worker Trial II

The vast majority of blindness is avoidable. The World Health Organization (WHO) estimates that 80% of cases of visual impairment could be prevented or reversed with early diagnosis and treatment. The leading causes of visual impairment are cataract and refractive error, followed by glaucoma, age-related macular degeneration (AMD), and diabetic retinopathy (DR). Loss of vision from these conditions is not inevitable; however, identifying cases early and linking cases with appropriate care remain significant challenges. To address the global burden of avoidable blindness, eye care systems must determine optimal strategies for identifying people with or predisposed to visual impairment beyond opportunistic screening. Outreach programs can prevent blindness both by screening for asymptomatic disease like age-related macular degeneration (AMD), diabetic retinopathy (DR), and glaucoma and case detection of symptomatic disease like cataract and refractive error. Eye care systems have developed numerous approaches to these identification methods, including screening using telemedicine and case detection via cataract camps or health worker models, but no studies have been conducted on the comparative effectiveness or cost effectiveness of these various approaches. Technology promises to greatly improve access to sophisticated eye care. AMD, DR, and glaucoma can result in irreversible vision loss, and early diagnosis and effective treatment can prevent progression. Thus, mass screen…
