A Review of the Published Literature in Global Population-Based Studies of Childhood Blindness and Vision Impairment.

Purpose: Reducing childhood blindness and vision impairment (BVI) remains a global health priority. Our purpose was to summarize the peer-reviewed literature to date on measuring and reporting childhood BVI using population-based surveys and vision examinations.

Methods: We conducted a scoping review of published studies that aimed to report BVI prevalence in children or studies that aimed to report BVI prevalence in the general population but which also included children.
