En el glaucoma de tensión normal, aun sin existir elevada presión intraocular, se producen lesiones del nervio óptico. De aquí que se haya pensado que ello es causa de otros mecanismos patogénicos y vasculares. Con todo, las causas exactas son todavía desconocidas.
Según publica la revista "Ophthalmologica", con la hipótesis de la asociación de SAS y glaucoma de tensión normal, el equipo de investigación suizo estudio el comportamiento durante el sueño de 16 pacientes. Todos ellos sufrían SAS. Mientras dormían se llevó a cabo una polisonografía. Para diagnosticar el grado de apnea durante el sueño, se utilizó el índice de trastorno respiratorio (ITR). Los pacientes con un índice igual o superior a 10 fueron diagnosticados como afectados por apnea del sueño.
La prevalencia de asociación entre ambas patologías fue de 0% en el grupo de pacientes menores de 45 años; de 50% (3 de 6), en pacientes de 45 a 64 años; y de 63% (5 de 8) en el grupo mayor de 64 años.
