Según informa "Archives of Ophthalmology", el estudio, prospectivo, se llevó a cabo sobre una muestra de profesionales sanos, femeninos y masculinos, entre 1980 y 1996. Los participantes tenían 40 años como mínimo y no sufrían glaucoma en el momento de iniciar la investigación.
Se analizaron factores comunes de riesgo de glaucoma de ángulo abierto primario, tales como la edad, la hipertensión y descendencia de etnia afroamericana. Los resultados indicaron que ni los fumadores activos ni los que ya habían abandonado este hábito presentaban mayor riesgo de desarrollar glaucoma de ángulo abierto primario que los no fumadores. Además, tampoco aumentaba este riesgo para los grandes fumadores.
Asimismo, se observó una pequeña relación inversa entre paquetes fumados al año y desarrollo de esta patología. En concreto, los fumadores de más de 30 paquetes anuales tenían un 22% de riesgo menor de desarrollar glaucoma de ángulo abierto primario que los no fumadores.
