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.

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.
