“…10 Compared with the upright posture, IOP has been shown to increase in the horizontal postures (supine, [11][12][13][14][15][16][17] prone, or lateral decubitus [18][19][20][21][22][23][24] ) in healthy and glaucomatous eyes. Such posture-induced IOP rise has been associated with progression of glaucomatous damage.…”

“…Such posture-induced IOP rise has been associated with progression of glaucomatous damage. 21,22,25 Some researchers studied the effect of sleeping in a head-up position using a wedge pillow in glaucoma patients 26,27 and healthy subjects, 27 and they demonstrated reduction of mean IOP by 1.5-3.2 mm Hg in the head-up position compared with the flat position. However, keeping the head up can be achieved by other methods such as using multiple pillows (MP) or raising the head of the bed.…”

Purpose To evaluate the effects of different methods of head elevation on intraocular pressure (IOP) in healthy young subjects. Methods Twenty-four healthy young Korean subjects were included in this prospective observational study. The IOP measurements were taken with the subjects in the sitting position and in the supine positions with the head flat and 301 up using two different methods: (1) raising the bed head and (2) using multiple pillows. IOP was measured using Tonopen AVIA in both eyes 10 min after assuming each position in a randomized sequence. The Wilcoxon signed-rank test was used to compare the IOP by changing the methods of head elevation. Results Mean IOP of both eyes when sitting was lower than that measured in the supine position with head flat (P ¼ 0.001). Compared with that measured in the supine position with head flat, the mean IOP was lower when measured in the supine position with the head kept 30 1 up by bed head elevation (P ¼ 0.001), whereas the mean IOP was not significantly different when measured in the supine position with the head elevated using multiple pillows (right eye, P ¼ 0.061; left eye, P ¼ 0.089). Conclusion In normal subjects, IOP was lower when measured in the supine position with the head kept up by the bed head elevation compared with that measured when lying flat. However, such head-up positioninduced IOP reduction was not found when the head was kept up using multiple pillows. These findings suggest that elevating the head using multiple pillows may not help to reduce IOP in the supine posture.

“…Primary open-angle glaucoma affects both eyes but often asymmetrically. 44 As found for sleep-related asymmetry exposure to elevated IOP 13 and, as discussed below, asymmetrical presentations of glaucomatous damage may be explained in part by corresponding asymmetrical exposures to IOP elevating activities unrelated to sleep. However, the survey only serves as a screening instrument.…”

“…For example, in glaucoma patients IOP elevation asymmetry during side sleeping was found to be associated with corresponding asymmetric field losses. 13 Correspondence between asymmetric exposure to elevated IOP and clinical findings suggest that appropriate behaviour modification to reduce exposure to IOP elevation for the more advanced eye could be more likely to be of benefit.…”

“…In assessing diurnal IOP variations the greatest interest has been in relation to supine sleep positions. 9---12 Side sleep positions have been shown to elevate IOP to higher levels than supine positions 13,14 and prone positions to even higher levels. 15 However, there are numerous other activities which are associated with elevated IOP in addition to those which are sleep-related (Table 1).…”

An examination of the hypothesis that intraocular pressure elevation episodes can have prognostic significance in glaucoma suspects

The efficacy of intraocular pressure reduction in retarding the progression of glaucoma has been demonstrated. This review examines the potential for prognostic advantage for glaucoma suspects in reducing their optic nerve head exposure to elevated intraocular pressure associated with activities which have been shown to elevate intraocular pressure. In this observational study, patients examined at the Centre for Eye Health (University of New South Wales) with a diagnosis of glaucoma suspect were surveyed to determine their histories for participation in activities which are known to elevate intraocular pressure. The evidence regarding the pathological significance of these sources of elevation in susceptible patients was examined. Apart from the universality of sleep-related intraocular pressure elevations, the histories from 183 confirmed glaucoma suspects indicate a wide range and variation in frequency of participation in other intraocular pressure elevating activities. A reduction in exposure to elevated intraocular pressure may improve the prognosis for glaucoma suspects. Additional patient specific assessment of the results of this screening could provide an indication of the degree (frequency, intensity level and duration) of exposure to elevated intraocular pressure. Such information may provide the basis for improving a patient's prognosis by helping them to identify opportunities to reduce such exposure to elevated intraocular pressure. Any benefit of reduction of such exposure appears likely to be greater if activities which elevate intraocular pressure are of long duration, occur frequently, occur over a long period of time, and/or involve high levels of intraocular pressure elevation.
