Abstract
Objective

Identify the prevalence of ocular manifestations due to vitamin A in children.

Methods

The systematic search was carried out in September 2022. Observational studies with populations between 0–18 years old, who had ocular manifestations due to vitamin A deficiency, were included. Studies with selected subjects with underlying diseases were excluded. The results were exported to the Rayyan tool for duplicate removal and paired reading. The methodological quality assessment of the included articles was carried out with the Agency for Healthcare Research and Quality Institute instrument.

Results

79 studies published from 1972 to 2020 were included, carried out mainly in Asia 42 (53%) and Africa 28 (35.4%). In America, 4 studies were from Brazil; no research was found in Europe. The most reported ocular manifestations due to vitamin A were: xerophthalmia in 38.0% of the articles and night blindness in 69.6%, being more common in the general population (76.3%) and less in aborigines (1.9%). The diagnostic methods used were: surveys (82.3%), laboratory tests (32%), ocular evaluation by optometry or ophthalmologist (25.3%) and ocular examination by trained personnel (8.9%). The studies were carried out in the general population (79.7%), hospitals (15.2%), schools for the blind (2.5%), migrants in transit (1.3%) and aborigines (1.3%).

Conclusion

Ocular manifestations continue to represent a public health problem that affects children from 0 to 18 years of age on 4 continents, with greater emphasis on Asia and Africa. Additional studies are required to understand the impact of vitamin A deficiency in Latin America.

Resumen
Objetivo

Identificar la prevalencia de manifestaciones oculares por avitaminosis A en niños.

Métodos

La búsqueda sistemática se realizó en septiembre del 2022. Se incluyeron estudios observacionales con poblaciones entre los 0–18 años, que tuvieran manifestaciones oculares por deficiencia de vitamina A. Se excluyeron estudios con sujetos seleccionados con enfermedades de base. Los resultados se exportaron a la herramienta Rayyan para la eliminación de duplicados y lectura pareada. Se realizó la evaluación de calidad metodológica de los artículos incluidos con el instrumento del Instituto Agency for Healthcare Research and Quality.

Resultados

Fueron incluidos 79 estudios publicados entre 1972 y 2020, realizados principalmente en Asia 42 (53%) y África 28 (35,4%). En América, 4 estudios fueron de Brasil; no se encontraron investigaciones en Europa. Las manifestaciones oculares por avitaminosis A más reportadas fueron: xeroftalmia en el 38,0% de los artículos y ceguera nocturna en el 69,6%, siendo más común en población general (76,3%) y menos en aborígenes (1,9%). Los métodos diagnósticos utilizados fueron: encuestas (82,3%), pruebas de laboratorio (32%), valoración ocular por optometría u oftalmología (25,3%) y examen ocular por personal entrenado (8,9%). Los estudios se realizaron en población general (79,7%), hospitales (15,2%), escuelas para ciegos (2,5%), migrantes en tránsito (1,3%) y aborígenes (1,3%).

Conclusión

Las manifestaciones oculares continúan representando un problema de salud pública que afecta a niños de 0 a 18 años en 4 continentes, con mayor énfasis en Asia y África. Se requieren estudios adicionales para conocer el impacto del déficit de vitamina A en Latinoamérica.
