Evaluación de la reproducibilidad de la retinoscopia dinámica monocular de Merchán

Abstract

Objetivo: Evaluar la reproducibilidad de la retinoscopia dinámica monocular y su nivel de acuerdo con la retinoscopia estática binocular y monocular, retinoscopia de Nott y Método Estimado Monocular (MEM). Métodos: Se determinó la reproducibilidad entre los evaluadores y entre los métodos por medio del coeficiente de correlación intraclase (CCI) y se establecieron los límites de acuerdo de Bland y Altman. Resultados: Se evaluaron 126 personas entre 5 y 39 años y se encontró una baja reproducibilidad interexaminador de la retinoscopia dinámica monocular en ambos ojos CCI ojo derecho: 0.49 (IC95% 0.36; 0.51); ojo izquierdo 0.51 (IC95% 0.38; 0.59). El límite de acuerdo entre evaluadores fue ±1.25 D. Al evaluar la reproducibilidad entre la retinoscopia dinámica monocular y la estática se observó que la mayor reproducibilidad se obtuvo con la estática binocular y monocular y, en visión próxima, entre el método estimado monocular y la retinoscopia de Nott. Conclusiones: La retinoscopia dinámica monocular no es una prueba reproducible y presenta diferencias clínicas significativas para determinar el estado refractivo, en cuanto a poder dióptrico y tipo de ametropía, por tanto, no se puede considerar dentro de la batería de exámenes aplicados para determinar diagnósticos y correcciones refractivas tanto en la visión lejana como en la visión próxima. Objective: To assess the reproducibility of monocular dynamic retinoscopy and its level of agreement with binocular static retinoscopy, the Nott retinoscopy, and the Monocular Estimated Method (MEM). Materials and methods: The reproducibility was determined among evaluators and among the methods through the intraclass coefficient of correlation (ICC) and set the limits of agreement of Bland and Altman. Results: A total of 126 subjects between 5 and 39 years of age were evaluated and low inter-rater reproducibility of the monocular dynamic retinoscopy was found in both eyes: ICC right eye: 0.49 (IC 95% 0.36; 0.61) left eye 0.51 (IC 95% 0.38; 0.59). The limit of agreement between evaluators was ±1.25D. In assessing reproducibility between the monocular dynamic retinoscopy and the static retinoscopy, it was observed that the greatest reproducibility was obtained with the binocular and monocular static retinoscopy and in near vision between the estimated method monocular and Nott retinoscopy. Conclusions: Monocular dynamic retinoscopy is not a reproducible test and presents clinical differences meaningful to determine the refractive state, regarding power dial and type of ametropy; therefore, it could not be considered within the battery of tests used to determine diagnoses and refractive corrections both in distant vision and in near vision.
