Intraocular pressure comparison between the lateral decubitus position and supine position for right/left eye at various nocturnal measured time points.
<p>Data are expressed as the mean ± SD; IOP: intraocular pressure; LDP: lateral decubitus position; Wilcoxon signed-rank test was used for the comparisons; P values less than 0.05 were considered significant.</p><p>* Intraocular pressure comparison between the right LDP and supine position for right/left eye;</p><p>** Intraocular pressure comparison between the left LDP and supine position for right/left eye.</p><p>Intraocular pressure comparison between the lateral decubitus position and supine position for right/left eye at various nocturnal measured time points.</p

Three 24-hour habitual intraocular pressure (IOP) patterns for the right eye.
<p>Three 24-hour habitual IOP patterns were obtained according to the diurnal sitting position (⧫) and nocturnal body positions, including supine position (△), right lateral decubitus position (○), and left lateral decubitus position (◊).</p

Estimation of 24-hour intraocular pressure (IOP) rhythm in each pattern for the left eye.
<p>The position of the acrophase around the circle shows its timing, and the radial distance from the center shows the amplitude of the IOP rhythm. The null hypothesis of a random circular distribution of acrophases was rejected by the Rayleigh test for each age group (p<0.001). The square (â–¡) represents the sitting-right LDP (LDP, lateral decubitus position) pattern; the rhombus (â—Š) represents the sitting-left LDP pattern; the dot (â—‹) represents the sitting-supine pattern.</p

Method of analyzing images.
<p>a. 570nm image; b. The vessels were minimum 50 pixels from the optic disc margin and at least 100 pixels from the edge of the image; c. Masking of vessel branchings and A-V crossings along with marking of 2 concentric circles within which vessel segments would be analysed; d. Vessel segment markings (thickest arteriole and venule per quadrant).</p
