Abstract

Purpose: To investigate the relationship between right-left sleep body position, as measured with a mobile device, and the progression of glaucoma asymmetry. We hypothesize that a patient’s preferred side of sleep position is associated with worsening of glaucomatous progression in the eye of the same side.

Methods: This was a single-masked, cross-sectional study. Primary open-angle glaucoma (POAG) patients with asymmetric glaucoma progression, as determined by perimetry, nerve fiber layer optical coherence tomography (OCT), and/or optic disc appearance, were enrolled. Home recordings of sleep body position were made over seven consecutive nights. A mobile device with the application Sleep Monitor was worn by the patient each night at bedtime. The right-left side sleep position in degrees was recorded, with positive angles indicating orientation on one side, negative angles on the other side, and zero degrees in the supine position. The overall sleep time in each position was also measured, as readings were logged every minute during sleep. The data were collected electronically, and the characteristic parameters of sleep body position were examined for a correlation with asymmetric glaucoma progression.

Results: Ten patients with diagnosed primary open-angle glaucoma (ages, 42 - 73 years) were included in the study. The average right-left sleep body position, as measured by the mean degree from supine, corresponded with glaucoma asymmetry progression in five patients, while the sleep body position did not correspond with glaucoma asymmetry progression in five patients.Fisher’s exact test showed no correlation between the side of sleep and the side of glaucoma (P=1.00)

Conclusions: In this pilot study, right-left sleep body position, as measured with a mobile device, demonstrated no significant correlation with the progression of glaucoma asymmetry in treated patients. The measurement of sleep body position with a mobile device offers a promising quantitative evaluation in the correlation between sleep body position and glaucoma asymmetry.
