Correlation between Intraocular Pressure Fluctuation with Postural Change and Postoperative Intraocular Pressure in Relation to the Time Course after Trabeculectomy

Figure 2

Posture-induced intraocular pressure (IOP) changes measured with an ICare rebound tonometer before and after trabeculectomy over an 18-month period. The IOPs in both the sitting and the lateral decubitus positions were decreased at every visit after the trabeculectomy (𝑃<0.01 every visit; Bonferroni test). The IOP in the lateral decubitus position was significantly increased (𝑃<0.05; paired 𝑡-test). The squares, upper bars, and lower bars indicate 25–75%, 95%, and 5% percentiles, respectively.
