ABSTRACT
INTRODUCCIÓN: La retinopatía del prematuro (ROP) es una de las principales causas de ceguera infantil potencialmente evitable. Los avances en los cuidados neonatales consiguen la supervivencia de niños de bajo peso extremo asociado con una mayor incidencia de la enfermedad. El objetivo de este estudio es evaluar la fiabilidad en el diagnóstico de la ROP a través de retinografías obtenidas con la cámara de campo amplio RetCam3 y estudiar la variabilidad en el diagnóstico de ROP en función del evaluador. MATERIAL Y MÉTODOS: El examen con oftalmoscopio indirecto fue realizado por un oftalmólogo pediátrico experto en ROP. Las imágenes retinianas fueron obtenidas por el mismo oftalmólogo y un técnico especializado en la captura de imágenes digitales. Un total de 30sets de imágenes fueron analizados por 3 grupos enmascarados: grupo A (8 oftalmólogos), grupo B (5 expertos en visión) y grupo C (2 oftalmólogos expertos en ROP). RESULTADOS: Acorde con el diagnóstico mediante oftalmoscopia indirecta, la sensibilidad (26-93), el índice Kappa (0,24-0,80) y el porcentaje de aciertos fueron estadísticamente significativos en el grupo C para el diagnóstico de ROP tipo1. En el diagnóstico de ROP tipo1+tipo2 el índice Kappa (0,17-0,33) y el porcentaje de aciertos (58-90) fueron estadísticamente significativos, obteniendo valores superiores en el grupo C. CONCLUSIONES: El diagnóstico realizado por oftalmólogos expertos en ROP con el retinógrafo móvil RetCam3 ha demostrado ser un método fiable
INTRODUCTION: The retinopathy of prematurity (ROP) is a potentially avoidable cause of blindness in children. The advances in neonatal care make the survival of extremely premature infants, who show a greater incidence of the disease, possible. The aim of the study is to evaluate the reliability of ROP screening using retinography imaging with the RetCam3 wide-angle camera and also study the variability of ROP diagnosis depending on the evaluator. MATERIAL AND METHODS: The indirect ophthalmoscopy exam was performed by a Pediatric ROP-Expert Ophthalmologist. The same ophthalmologist and a technician specialized in digital image capture took retinal images using the RetCam3 wide-angle camera. A total of 30image sets were analyzed by 3 masked groups: group A (8 ophthalmologists), group B (5 experts in vision), and group C (2 ROP-expert ophthalmologists). RESULTS: According to the diagnosis using indirect ophthalmoscopy, the sensitivity (26-93), Kappa (0.24-0.80), and the percent agreement were statistically significant in group C for the diagnosis of ROP Type1. In the diagnosis of ROP Type1+Type2, Kappa (0.17-0.33) and the percent agreement (58-90) were statistically significant, with higher values in group C. CONCLUSION: The diagnosis, carried out by ROP-expert ophthalmologists, using the wide-angle camera RetCam3 has proved to be a reliable method
