Introducción. La miopía es una causa de discapacidad visual que repercute en el desarrollo de niños y adolescentes. El uso de apps de agudeza visual es una alternativa de tamizaje para médicos generales, técnicos en salud y legos. Objetivos. Evaluar la concordancia entre la evaluación de agudeza visual mediante app en niños de 6 a 17 años por profesores frente al método tradicional con cartilla de Snellen por un técnico de salud. Materiales y métodos. Estudio observacional analítico transversal; se realizaron tres evaluaciones ciegas e independientes (tabla de Snellen tradicional a seis metros, app de agudeza visual por optometrista y la misma app por profesor), previo consentimiento y asentimiento informados a 196/252 escolares. Se trabajó en unidades logMAR y se usó el coeficiente de Lin para evaluar la concordancia entre estos y se representó mediante gráficos de Bland-Altman. Resultados. La edad promedio fue 11,28 ±3,07 años; 55,61% fueron varones; diez salones fueron evaluados; los alumnos de primaria corresponden al 46,94%; 57,14% no utiliza lentes y solo el 51,53% ha sido evaluado previamente por un especialista. En el análisis de todos los salones, se obtuvo una concordancia con Lin baja (hasta 0,322) entre las mediciones. Conclusión. No es aplicable el uso de la app en lugar del método tradicional de medición de agudeza visual. / UTILITY OF A VISUAL ACUITY APP AND NEED OF OPHTHALMOLOGIC EVALUATION IN A PRIVATE SCHOOL OF CALLAO - 2005 ABSTRACT Introduction. Myopia is a cause of visual impairment that affects the development of children and adolescents. The use of visual acuity apps is an alternative for healthcare providers and non-healthcare professionals. Objectives. To evaluate the agreement between visual acuity assessment with an app performed by teachers against to the traditional Snellen chart performed by an optometrist in children of 6 to 17 years old. Materials and methods. Cross-sectional, analytical and observational study; three blind and independent evaluations were carried out (Snellen chart at 20 feet, visual acuity app by optometrist and the same app performed by teacher) to 196/252 school children. Values were changed to logMAR and the Lin coefficient was used to assess the concordance between them and was represented by Bland-Altman plots. Results. The mean age was 11.28 ±3.07 years; 55.61 % were male; ten classrooms were evaluated; elementary students correspond to 46.94 %; 57.14 % do not use lenses and only 51.53 % has been previously evaluated by a specialist. In the analysis of all classrooms, a low concordance with Lin coefficient (up to 0.322) between measurements was obtain. Conclusion. The Snellen chart can’t be replaced with the visual acuity app chosen for the study. Key words. Visual Acuity; Myopia; Mobile Applications; Child; Optometry, Peru (source: MeSH NLM) / Tesis
