Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Worldwide, eye health care systems must determine optimal strategies for reaching people outside of their immediate orbit in order to reduce visual impairment. Visual impairment can be reduced by case detection of prevalent disease like cataract and refractive error, or by screening for early disease like glaucoma, AMD, and DR and preventing progression. Systems around the world have developed numerous approaches to both case detection and screening but there is very little research to support the choice of allocating resources to case detection or screening and little data exists on the cost effectiveness of the various approaches to each.
VIEW II Pilot is a cluster-randomized trial to determine the effectiveness of different approaches to community-based case detection and screening for ocular disease. Communities in Nepal will be randomized to one of four arms: 1) a comprehensive ocular screening program, 2) a cataract camp-based program, 3) a community health worker-based program, and 4) no program.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Specific Aim 2: to determine whether a community health volunteer program increases the rate of cataract surgery compared to a no program.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Community-based screening
Community-based screening program
In communities randomized to receive the screening program, all adults aged 50 and older will be eligible to receive screening for ocular disease. Screening assessments include visual acuity, refraction, intra-ocular pressure, fundus photography, and anterior segment photography. Participants meeting criteria for referral based on screening assessments will be referred to the nearest eye care center or eye hospital for further evaluation.
Cataract camp program
Cataract camp program
In communities randomized to receive the cataract camp program, all adults aged 50 and older will be eligible to participate in a routine cataract camp run by Bharatpur Eye Hospital. Trained ophthalmic personnel and assistants will perform case detection for cataract via visual acuity, pen light exam, and indirect ophthalmoscope exam per Bharatpur Eye Hospital's standard cataract camp program. Participants with cataracts will be referred to the nearest eye care center or eye hospital for further evaluation.
Community health worker program
Community health worker program
In communities randomized to receive the community health worker program, all adults aged 50 and older will be eligible to participate. Existing community health workers will be trained to perform case detection for cataract via visual acuity assessment. Participants with cataracts will be referred to the nearest eye care center or eye hospital for further evaluation.
