To investigate the pupillary diameter and light response in patients who have recovered from COVID-19.Thirty two eyes of 32 with a history COVID-19 last months age sex-matched healthy controls were included this prospective study. All had neurological symptoms. Dynamic static pupillometry measurements performed Sirius (CSO, Italy) corneal topography device.Patients higher mean scotopic, mesopic, photopic pupil diameters compared to (p = .01, p .04, .02, respectively). In dynamic analysis, 0th, 2th, 8th 16th second There no differences average speed dilatation > .05).Our findings suggest that response, an indicator autonomic nervous system activity, may be affected

To evaluate the effects of stimulus intensity, aging, sex, smoking and eye symmetry on pupillary light reflex (PLR) parameters.We evaluated 2812 eyes from 1406 subjects in a single-centre, cross-sectional study. PLR data were collected using four different intensities. We prepared two models for each eight parameters, defined model with lowest values Akaike's information criterion (AIC) as being best-fit. Model A was linear regression without adjustment among-individual variability, while B mixed-effects (LMMs) adjusted variability. The coefficients compared.Model showed AIC all parameters best fit. For age symmetry, yielded similar results parameters. sex index, some opposite results, i.e., significant did not.These indicate that are factors affect These should be when evaluating clinical potential diagnostic tool. In addition, adjusting variability due to LMMs can improve fit reduce false positives. This reveal association between increased accuracy.

This study aimed to evaluate glare source-induced disk halo size and assess its correlation with higher-order aberrations (HOAs), pupillometry findings, contrast sensitivity in myopic adults (aged 23.8 ± 4.4 years). In this cross-sectional study, 150 eyes of patients were assessed. All underwent routine ophthalmic examinations, wavefront aberrometry, measurement, dynamic pupillometry, tests. Spearman's analysis independent sample t -tests performed for data analysis. The mean radius was 82.5 21.8 236.7 52.2 arc min at 5 1 cd/m 2 luminance levels, respectively. values inversely correlated internal spherical aberration (SA) ( r = −0.175, p 0.032 −0.241, 0.003, respectively), but not equivalent (SE, both > 0.05). Positive correlations observed between pupil size, contraction amplitude, dilation speed during pupillary light reflex. Halo radii levels significantly the area under log function −0.093, 0.258 −0.149, 0.069, respectively). clinically different healthy level did differ high low-to-moderate myopia (all According a stepwise linear regression model, SA had negative effect on low photpic condition; average diameter, corneal HOAs played large role determining mesopic condition.

Automated pupil light reflex (PLR) is a valid indicator of dysfunctional autonomic brain function following traumatic injury. PLR's use in identifying disturbed repeated head impacts without outwardly visible symptoms has not yet been examined. As combat sport featuring 'sub-concussive' impacts, mixed martial arts (MMA) sparring may provide model to understand such changes. The aim this pilot study was explore which, if any, PLR variables are affected by MMA sparring. A cohort n = 7 athletes (age 24 ± 3 years; mass 76.5 9 kg; stature 176.4 8.5 cm) took part their regular sessions (eight rounds × min: 1 min recovery). both eyes measured immediately pre- and post-sparring using Neuroptic NPi-200. Bayesian paired samples t-tests (BF10 ≥ 3) revealed decreased maximum size 3), minimum 4) reduced latency post-sparring. Anisocoria present prior increased post-sparring, with having different sizes 3-4) constriction velocities 3). These data suggest cause disturbances the absence symptoms. results direction for cohort-controlled studies formally investigate potential changes observed.

BackgroundTo compare the static and dynamic pupillometry measurements in patients with pseudoexfoliation syndrome (PES), glaucoma (PEG) age‐matched healthy subjects using an automatic quantitative system.MethodsThis prospective, cross‐sectional study consisted of 40 PES, 30 PEG 43 control subjects. Static including scotopic pupil diameter, mesopic low photopic high diameter were undertaken. Subsequently, resting amplitude contraction, latency duration velocity dilation, dilation These compared between groups.ResultsThe scotopic, mesopic, values statistically significantly lower PES controls (p < 0.001). However, these parameters similar > 0.05). The mean within all groups = 0.54). contraction was than Patients also had Additionally, higher when to 0.05).ConclusionThis demonstrated that accumulation pseudoexfoliative material can cause alterations pupillary characteristics progression from may be associated reduced values.
