(2021). Can dynamic and static pupillary responses be used as an indicator of autonomic dysfunction in patients with obstructive sleep apnea syndrome? International Ophthalmology, 41(7), 2555-2563.0165-57011573-2630https://link.springer.com/content/pdf/10.1007/s10792-021-01814-0.pdfhttps://hdl.handle.net/11468/10005WOS:000632380600003PMID: 33763793Purpose We aimed to reveal whether static and dynamic pupillary responses can be used for the detection of autonomic nervous system (ANS) dysfunction in patients with obstructive sleep apnea syndrome (OSAS). Methods We included in this study patients with OSAS, who were divided into three groups according to the apnea-hypopnea index (AHI) (group 1, mild [n = 20]; group 2, moderate [n = 20]; and group 3, severe [n = 20]), and healthy controls (group 4, n = 20). Pupillary responses were measured using a pupillometry system. Results Static (mesopic PD, P = 0.0019; low photopic PD, P = 0.001) and dynamic pupil responses (resting diameter, P = 0.004; amplitude of pupil contraction, P < 0.001; duration of pupil contraction, P = 0.022; velocity of pupil contraction, P = 0.001; and velocity of pupil dilation, P = 0.012) were affected in patients with different OSAS severities. Also, AHI was negatively correlated with mesopic PD (P = 0.008), low photopic PD (P = 0.003), resting diameter (P = 0.001), amplitude of pupil contraction (P < 0.001), duration of pupil contraction (P = 0.011), velocity of pupil contraction (P < 0.001), and velocity of pupil dilation (P = 0.001). Conclusion We detected pupil responses innervated by the ANS were affected in the OSAS patients. This effect was more significant in the severe OSAS patients. Therefore, the pupillometry system can be an easily applicable, noninvasive method to detect ANS dysfunction in the OSA patients.eninfo:eu-repo/semantics/openAccessPupillometryObstructive sleep apnea syndromeAutonomic dysfunctionDiabetic autonomic neuropathyArticle41725552563WOS:0006323806000032-s2.0-851033502833376379310.1007/s10792-021-01814-0Q2Q3
