- W3210833796 abstract "La retinoscopia, como técnica objetiva de evaluación del estado refractivo, es especialmente útil en la edad infantil. La técnica de Mohindra (RM) es una alternativa para aquellos pacientes en los que no es viable la retinoscopia mediante ciclopléjico (RC). En el presente estudio se pretende comparar ambas técnicas para determinar su correlación y concordancia.Se seleccionaron a 47 niños y niñas con edades comprendidas entre los 3 y 11 años. Se determinó para ambos ojos la refracción con RM y RC (ciclopentolato 1%), así como con autorefractómetro (AR). Se compararon los resultados de las tres técnicas y se calculó el factor de corrección correspondiente para equiparar RM con RC.Se encontraron diferencias significativas entre RM y RC (mediana de -0,42 D; p< 0,001) y entre RM y AR (mediana de -0,42 D; p = 0,008), pero no entre RC y AR (mediana de 0,00 D; p = 0,758). La correlación entre RM y RC fue excelente (rho = 0,846; p< 0,001) pero el test de Bland-Altman evidenció una mayor discrepancia entre técnicas a medida que aumentaba la refracción hipermetrópica, con un factor de corrección de RC = 1,15 RM + 0,42.La técnica de Mohindra se puede considerar como una alternativa válida a la retinoscopía mediante ciclopléjico en pacientes en edad escolar y preescolar, con una buena correlación entre ambas técnicas, pero con menor concordancia en hipermetropías elevadas.As an objective technique to assess refractive status, retinoscopy is particularly useful in children. The Mohindra technique (RM) is an alternative for those patients not good candidates for cycloplegic retinoscopy (RC). The aim of the present research was to compare both techniques and to determine the correlation and agreement of their measurements.A total of 47 boys and girls of ages ranging from 3 to 11 years old were included in the study. Cycloplegic (cyclopentolate 1%) and Mohindra retinoscopy were conducted in both eyes, and refraction was also assessed with an autorefractometre (AR). The results from the three techniques were compared and a correction factor between RM and RC was calculated.Statistically significant differences were found between RM and RC (median of -0.42 D; p< 0.001) and between RM and AR (median of -0.42 D; p = 0.008), but not between RC and AR (median of 0.00 D; p = 0.758). A strong correlation was found between RM and RC (rho = 0.846; p< 0.001), although the Bland-Altman test revealed a larger difference between these techniques in patients with larger hyperopic refractive errors, with a correction factor of RC = 1.15 RM + 0.42.The Mohindra technique may be considered a valid alternative to cycloplegic retinoscopy in patients of young age, with a good correlation between both techniques, albeit less agreement in patients with high hyperopic refractions." @default.
