Abstract
A B S T R A C T S (1.7 0.3 vs. 2.2 0.9, P1⁄40.012) and PPC (26.8 7.2 vs. 33.9 7.1, P1⁄40.004) were significantly lower in patients with sTAA than the control group. There was a moderate negative correlation between maximal aortic diameter and amplitude of pupil contraction (r1⁄4-0.684, p1⁄4 0.001), velocity of pupil contraction (r1⁄4-0.662, p1⁄4 0.001) and PPC (r1⁄4-0.612, p1⁄4 0.001). In addition, there was a weak negative correlation between maximal aortic diameter and velocity of pupil dilatation (r1⁄4-0.410, p1⁄4 0.01). Conclusions: Patients with sTAA have lower amplitude of contraction; contraction and dilatation velocity and PPC. These findings are implying the presence of autonomic dysfunction in patients with sTAA, especially in higher maximal aortic diameter.
