Sleeping posture and intraocular pressure.
INTRODUCTION This prospective observational case series aimed to determine whether the lateral decubitus position, which is commonly adopted during sleep, has an effect on intraocular pressure (IOP) in normal controls. METHODS Patients without glaucoma were recruited from those visiting outpatient clinics for non-glaucomatous conditions. The left eye of each patient was included. IOP was firs...
متن کاملPressure-Sensor System for Sleeping-Posture Classification
In this paper we present our research work on the classification of sleeping postures using pressure sensing. A densely pressure-sensor grid placed under the matrass is first used for the posture classification task that will serve next as a reference. Pressure data obtained from 21 subjects for 4 sleeping postures (supine, prone, left and right side) has been analysed to determine the optimal ...
متن کاملThe pressure difference between eye and brain changes with posture.
OBJECTIVE The discovery of a posture-dependent effect on the difference between intraocular pressure (IOP) and intracranial pressure (ICP) at the level of lamina cribrosa could have important implications for understanding glaucoma and idiopathic intracranial hypertension and could help explain visual impairments in astronauts exposed to microgravity. The aim of this study was to determine the ...
متن کاملPosture and Limb Detection for Pressure Ulcer Prevention
Pressure ulcers impose an enormous burden on health care system. For hospitalized patients, the prevalence ranges from 3% to 11% increasing both the length of hospital stay and hospital cost. Pressure ulcer results in a skin breakdown that happens when a patient stays in bed for a long time without dynamically shifting the body weight over the surface. Bedridden patients, immobile nursing home ...
متن کاملVisual Influences on Center of Pressure Dynamics in Upright Posture
In 2 experiments, participants stood upright with their eyes open or closed and fating forward or to the side; the 2nd experiment also included a manipulation of optical structure. At issue were the effects of different conditions of visual exproprioperception on motions of the body's center of pressure. Also at issue was the utility of 2 characterizations of postural control under the vision m...
