Los pilotos de líneas aéreas tienen más riesgo de desarrollar cataratas debido a su exposición a los rayos cósmicos, según una investigación desarrollada en la Universidad de Islandia en Reykjavik que publica “Archives of Ophthalmology”.
En este estudio de casos y controles incluyeron a un grupo de 445 hombres de 50 o más años, de los que 79 eran pilotos. De estos últimos, 71 tenía cataratas, por lo que concluyeron que los pilotos tenían tres veces mayor riesgo de cataratas. Tras ajustar los resultados por edad, tabaquismo y exposición al sol, observaron que la radiación cósmica puede ser el factor causal. Los autores también señalan que en los astronautas también se ha demostrado un mayor riesgo de cataratas, y que en su estudio el tabaquismo se relacionó, asimismo, con un incremento del riesgo.
