    Glaucoma

    Glaucoma is a condition in which the pressure within the eyeball rises, leading to impaired eye circulation and, ultimately, to eye damage and possible blindness.

    Research has shown that pressure within the eye goes up when a person lies down, and goes down when the person sits up. A slight head elevation can lower eyeball pressure and should have been used as a treatment for glaucoma.

    It has been ignored, however, due to the cultural assumption that head elevation during sleep is not a medical issue. Nevertheless, sleeping with the head too flat for too long over many years pressurizes the eyeballs as well as the brain, slowly creating glaucoma.

    To perform the following SELF STUDY, you may want to get your eyeball pressure checked before and after the study period, since this is the only way to tell whether or not your eye pressure has changed.

    Mensen met oogproblemen ondervinden meer problemen met de oogdruk als zij horizontaal liggen:

    Posture-induced intraocular pressure changes: considerations regarding body position in glaucoma patients.
    Prata TS1, De Moraes CG, Kanadani FN, Ritch R, Paranhos A Jr.

    Although glaucoma is a multifactorial disease, elevated intraocular pressure (IOP) remains the most important known risk factor. Different systemic and local factors are thought to influence an individual’s IOP. There can be a clinically significant rise in IOP when going from upright to horizontal or inverted body positions. Although there is a significant interindividual variability, the magnitude of the IOP change is greater in glaucomatous eyes. As patients usually spend a significant portion of their lives in the horizontal position, mainly during sleep, this is highly relevant. In this review we discuss the relationship between postural changes and IOP fluctuation, including changes in both body and head position. The possible mechanisms involved and the main implications for glaucomatous eyes are discussed. Finally, considerations with regard to sleep position in glaucoma patients are made based on evidence in the literature.
