Effect of prolonged supine position on the intraocular pressure in patients with obstructive sleep apnea syndrome

Abstract

IOP increase is significantly more in OSAS patients on prolong supine position.

Intraocular pressure response affected by changing of sitting and supine positions

“…The immediate increase (2.6 AE 2.4 mmHg) after lying down compared to the baseline as well as the higher mean IOP in the lying period compared to the sitting period (1.41 AE 2.4 mmHg) are consistent with the published studies in the case of the normal healthy subjects (e.g. Jorge et al 2010;Fang et al 2018;Lam et al 2013;Lee et al 2012;Lind en et al 2018;Malihi & Sit 2012;Parsley et al 1987) as well as the subjects with glaucoma (e.g. Anderson & Grant 1973;Kiuchi et al 2010;Lind en et al 2018;Parsley et al 1987).…”

“…The gradual IOP decrease in the supine position was not observed previously (e.g. Fang et al 2018). Due to this decrease, the IOP reached values close to the baseline in minute 15; the higher baseline led to the major decrease.…”

“…Due to this decrease, the IOP reached values close to the baseline in minute 15; the higher baseline led to the major decrease. In contrast, Jorge et al 2010;Lam et al 2013;Fang et al 2018 found a significant difference from the baseline after 15 or 30 min in the supine position in the case of normal healthy subjects (Jorge et al 2010;Lam et al 2013;Fang et al 2018). This discrepancy could be explained by the observed dependence of the IOP changes on the baseline (see Fig.…”

“…Intraocular pressure (IOP) is significantly affected by body position as well (e.g. Jorge et al 2010;Fang et al 2018;Kiuchi et al 2010;Lam et al 2013;Lee et al 2012;Lind en et al 2018;Malihi & Sit 2012;Meurs et al 2018; for a review of older studies see Prata et al 2010). The most studies refer to the higher IOP values in the supine compared to the sitting or upright position (e.g.…”

“…The most studies refer to the higher IOP values in the supine compared to the sitting or upright position (e.g. Galin et al 1963;Linder et al 1988;Jorge et al 2010;Kiuchi et al 2010;Lee et al 2012;Malihi & Sit 2012;Lam et al 2013;Fang et al 2018;Lind en et al 2018;Meurs et al 2018). Such an increase in IOP as well as its quick changes can be a risk factor for development and progression of glaucoma (e.g.…”
