Abstract
Introducción: La retinopatía del prematuro (ROP) es una causa potencialmente evitable de ceguera en niños. Los avances en la atención neonatal posibilitan la supervivencia de bebés extremadamente prematuros, que presentan una mayor incidencia de la enfermedad. El objetivo del estudio es evaluar la fiabilidad del cribado de ROP mediante retinografía con la cámara gran angular RetCam 3 y también estudiar la variabilidad del diagnóstico de ROP según el evaluador.
Material y métodos: El examen de oftalmoscopia indirecta fue realizado por un Oftalmólogo Pediátrico Experto en ROP. El mismo oftalmólogo y un técnico especializado en captura de imágenes digitales tomaron imágenes de retina utilizando la cámara gran angular RetCam 3. Un total de 30 conjuntos 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: Según el diagnóstico mediante oftalmoscopia indirecta, la sensibilidad (26-93), Kappa (0,24-0,80) y el porcentaje de concordancia fueron estadísticamente significativos en el grupo C para el diagnóstico de ROP Tipo 1. En el diagnóstico de ROP Tipo 1 +Tipo 2, Kappa (0,17-0,33) y el porcentaje de acuerdo (58-90) fueron estadísticamente significativos, con valores superiores en el grupo C.
Conclusión: El diagnóstico realizado por oftalmólogos expertos en ROP con la cámara gran angular RetCam 3 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: groupA (8 ophthalmologists), groupB (5 experts in vision), and groupC (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 groupC. Conclusion: The diagnosis, carried out by ROP-expert ophthalmologists, using the wide-angle camera RetCam3 has proved to be a reliable method.
