ACUNA, Lizbeth; URIBE, María Mónica  e  OROZCO, Luis Carlos. Evaluation of the reproducibility of the Merchán monocular dynamic retinoscopy. Colomb. Med. [online]. 2009, vol.40, n.4, pp.399-407. ISSN 1657-9534.

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.
