Abstract
Background: The role of key informants (KIs) in identifying children with vision loss is expanding, yet there is a minimal understanding of KI perceptions of vision loss in children. The aim of the study was to understand the KI’s perception of childhood vision loss in order to design more effective training programmes. Materials and Methods: A population-based study on the prevalence and causes of childhood blindness and severe visual impairment was conducted using the KI method. KIs were selected by their communities and trained in advocacy, identifi cation and referral of children with visual impairment. Prior to the KI training, a pre-test was conducted, asking, “what is your perception of vision loss in children and how will you identify these children in your community?”. Result: The 742 KI provided 1,650 responses. There were three main methods suggested to identify children; observation of a child, vision assessment of a child, and recognition of isolation of a child. Conclusion: KI have a good understanding of the impact of vision loss on children. Training programmes should use existing knowledge of KI. Furthermore, training programmes should include the social impact of severe vision loss to help identify children needing the assessment. Keywords: Childhood blindness, key informant, Nigeria, perception, vision
