Update on Epidemiologic Trends in Causes of Childhood Blindness and Severe Visual Impairment in East Africa

Abstract

BL/SVI due to the cornea was among the common anatomic sites of disease in our study. The identification of measles as an associated systemic etiology requires further understanding in the context of increased vaccination programs. Multiple articles acknowledged that cataract has become the predominant cause of BL/SVI owing to increased measles vaccination and vitamin A supplementation. Additional research should be conducted to gain a complete understanding of childhood BL/SVI in East Africa, and responses at regional and national levels are likely necessary to address treatable causes of vision impairment.
