2. Sensitivity and Specificity of Red Reflex Test in Newborn Eye Screening. (PubMed)

Sensitivity and Specificity of Red Reflex Test in Newborn Eye Screening. To validate the sensitivity of an isolated red reflex test in detection of ocular abnormalities of the anterior and posterior segments in newborns.Red reflex test and comprehensive eye examinations including external inspection, pupil examination, hand-held slit lamp examination, and RetCam fundus imaging (Clarity Medical Systems, Pleasanton, California) were performed in 7641 newborns. All results were documented (...) as negative or positive. Sensitivity and specificity of red reflex test were calculated by the use of comprehensive eye examinations as the reference standard. Anterior abnormalities were separated from posterior abnormalities, and the sensitivity of red reflex test for each group was calculated.The proportion of abnormalities that were correctly classified by red reflex test was greater in anterior segment group (sensitivity = 99.6%, 95% CI 97.1%-100%) than in the posterior group (sensitivity = 4.1%, 95

6. Melanopsin-mediated pupillary light reflex and sleep quality in patients with normal tension glaucoma. (PubMed)

Melanopsin-mediated pupillary light reflex and sleep quality in patients with normal tension glaucoma. The intrinsically photosensitive retinal ganglion cells (ipRGCs) and sleep quality are impaired in patients with primary open-angle glaucoma (POAG). In this study, we investigated whether ipRGCs and sleep quality were also impaired in patients with normal tension glaucoma (NTG).We performed pupillometry and sleep quality assessment in 15 patients with NTG and 17 healthy age-matched controls (...) . Pupillometry protocol consisted of monocular stimulation with high illuminance (100 lux) red (633 nm, 300 cd/m2 or 15.23 log quanta/cm2 /s) and blue light (463 nm, 332 cd/m2 or 15.27 log quanta/cm2 /s) and binocular pupil measurements. Prior to light stimulation, patients were dark-adapted for 5 min. The late postillumination pupillary response (PIPRLate ) to blue light was used as marker of ipRGC activity. Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI) questionnaire.The PIPRLate

pressor response to static exercise in PAD. We hypothesized that limb ischemia impairs muscle superoxide dismutase (SOD) thereby leading to abnormal autonomic responsiveness observed in PAD animals, and a chronic compensation of SOD for anti-oxidation improves the exaggerated exercise pressor reflex. Our data show that femoral occlusion decreased the protein levels of SOD in ischemic muscle as compared with control muscle. Downregulation of SOD appeared to a greater degree in the oxidative (red (...) Local Injections of Superoxide Dismutase Attenuate the Exercise Pressor Reflex in Rats with Femoral Artery Occlusion The exercise pressor reflex is amplified in patients with peripheral artery disease (PAD) and in an experimental PAD model of rats induced by femoral artery occlusion. Heightened blood pressure worsens the restricted blood flow directed to the limbs in this disease.

11. Analysis of basal and reflex human tear osmolarity in normal subjects: assessment of tear osmolarity (PubMed)

Analysis of basal and reflex human tear osmolarity in normal subjects: assessment of tear osmolarity The aim of this study is to evaluate the difference between reflex and basal tear osmolarity among healthy normal subjects.The right eyes of 20 healthy normal male subjects aged 20 to 40 years were recruited for this study. The inclusion criteria for the subjects were the Ocular Surface Disease Index questionnaire score of less than 12 and wetting length of the phenol red thread of more than 10 (...) mm. Tear film osmolarity was assessed using TearLab osmometer. Basic tear osmolarity was measured normally without inducing any irritation to the eye. In order to stimulate reflex tear, subjects were asked to open their eye as long as they can till they feel ocular surface irritation (minimum 20 s).The mean score on the Ocular Surface Disease Index questionnaire was 5.5 ± 3. The mean value obtained from the phenol red thread was 21 ± 4.5 mm. There were no statistically significant differences

Neurovascular mechanisms underlying augmented cold‐induced reflex cutaneous vasoconstriction in human hypertension In hypertensive adults (HTN), cardiovascular risk increases disproportionately during environmental cold exposure. Despite ample evidence of dysregulated sympathetic control of the peripheral vasculature in hypertension, no studies have examined integrated neurovascular function during cold stress in HTN.

Reflex vasodilation was elicited in 13 young [23 ± 1 (SE) yr] and 13 older (67 ± 2 yr) adults using a water-perfused suit to elevate esophageal temperature by 1.0°C. SSNA (peroneal microneurography) and red cell flux (laser Doppler flowmetry) in the innervated dermatome (the dorsum of foot) were continuously measured. SSNA was normalized to, and expressed (...) Blunted increases in skin sympathetic nerve activity are related to attenuated reflex vasodilation in aged human skin Reflex cutaneous vasodilation in response to passive heating is attenuated in human aging.

20. Effect of topical anti-glaucoma medications on late pupillary light reflex, as evaluated by pupillometry. (PubMed)

Effect of topical anti-glaucoma medications on late pupillary light reflex, as evaluated by pupillometry. The late post-illumination pupillary response (PIPR 10-30s ) to blue light is reduced in glaucoma, suggesting that pupillometry can be used in clinical glaucoma evaluation. Since animal studies have indicated that common anti-glaucomatous agents affect the iris muscle, we investigated the short-term effect of the anti-glaucoma drugs on the pupillary light reflex and in particular (...) on the PIPR10-30s.In this randomized, double-masked, crossover trial, pupillometry was performed before and after topical administration of latanoprost, dorzolamide, and timolol in 20 healthy subjects. Stimulus was blue (463 nm) and red light (633 nm) of 2 log (lux). Main outcome was the PIPR10-30s to blue light. Additionally, pupil size, maximal contraction, and the early post-illumination pupillary response (PIPR 0-10s ) to blue and red light were investigated. Pupil response variations between 8 a.m
