Assessment of pupillary autonomic functions by dynamic pupillometry in different circadian arterial blood pressure patterns.

Objective: The aim of the present cross-sectional study was to evaluate the autonomic nervous system by dynamic pupillometry (DP) in normotensive and hypertensive individuals with either a non-dipper-type or a dipper-type circadian rhythm of blood pressure (BP).

Patients And Methods: A total of 80 patients were allocated into four groups: normotensive/dipper (n=23), normotensive/nondipper (n=19), hypertensive/dipper (n=18), and hypertensive/nondipper (n=20). Pupil diameters (R0, R1, R2, and R%): latency (Lc), amplitude (Ac), velocity (Vc), and duration (Tc) of pupil contraction: latency (Ld), velocity (Vd), and duration (Td) of pupil dilatation were measured by DP.

Computerized dynamic pupillometry indices mirrors the heart rate variability parameters.

Objective: Dynamic pupillometry (DP) is a simple, non-invasive computerized assessment of pupillary light response which provides data concerning both branches of the autonomous nervous system (ANS). Heart rate variability (HRV) analysis assess cardiac health and the ANS modulation on the heart. In this study, we aimed to evaluate the utility of DP as a predictor of cardiac autonomic activity assessed by HRV.

Assessment of the relationship between dynamic pupillometry and exercise heart rate recovery among healthy subjects.

Objective: Dynamic pupillometry (DP) is a simple, non-invasive computerized technique for assessment of pupillary light response which provides data concerning the balance of both branches of the autonomous nervous system (ANS). Heart rate (HR) recovery (HRR) after graded exercise reflects cardiac autonomic activity and predicts cardiovascular events. In this study, we aimed to evaluate the utility of DP as a predictor of cardiac autonomic activity assessed by HRR.

Plasma coenzyme Q10 levels in type 2 diabetic patients with retinopathy.

Aim: To determine the relationship between proliferative diabetic retinopathy (PDRP) and plasma coenzyme Q10(CoQ10) concentration.

Methods: Patients with type 2 diabetes and PDRP were determined to be the case group (n=50). The control group was consist of healthy individuals (n=50).

Retinal nerve fiber layer thickness analysis in suspected malingerers with optic disc temporal pallor.

Purpose: To investigate the value of temporal retinal nerve fiber layer (RNFL(temporal)) thickness in the prediction of malingering.

Materials And Methods: This prospective, cross-sectional study was conducted on 33 military conscripts with optic disc temporal pallor (ODTP) and 33 age-and sex-matched healthy controls. Initial visual acuity (VA(i)) and visual acuity after simulation examination techniques (VA(aset)) were assessed.
