COMMON CAUSES OF VISUAL IMPAIRMENT IN CHILDREN: LITERATURE REVIEW

Objective: This review aims to identify and analyze the most prevalent causes of vision impairment in children, focusing on the prevalence of each condition and recommended strategies for prevention and early intervention to mitigate developmental impacts. Methodology: A PRISMA-based systematic review was conducted, analyzing data from eight studies published over the last 10 years. The review involved searches in databases such as PubMed, Web of Science, and Scopus, using the search algorithm (“low vision” OR “visual impairment”) AND cause AND child. Results: Refractive errors were the most common cause of visual impairment in children, accounting for 38.6% to 86.6% of cases. The second most prevalent cause was congenital cataracts, contributing to 39.1% of cases. Other region-specific causes included albinism and neonatal conditions, as well as cortical visual impairment and retinopathy of prematurity. Conclusion: The literature indicates that refractive errors and cataracts are the leading causes of childhood visual impairment, with distinct regional differences underscoring the need for both universal and targeted strategies, including regular screenings, public health education, and enhanced access to treatment.
