Intro: The purpose of this study was to investigate the effects of quiet eye training (QET) on inhibitory control, visuospatial working memory (WM), and tonic attention in children with attention-deficit hyperactivity disorder (ADHD).
Methods: Forty-eight children with ADHD aged 9-12 years were randomly assigned to QET and control (CON) groups. The QET group practiced targeted hand-eye tasks within a QET protocol developed to optimize controlled attention and gaze through eye fixations. We used the go/no-go (GNG) test, the Corsi test, and the reaction test of alertness (RTA) to verify the effects of QET on inhibition control, WM, and tonic attention.
Results: QET group showed significantly shorter reaction times, a higher number of correct responses, and a lower number of omissions in the GNG inhibition test after QET as compared to the pre-measurements, whereas the CON group did not demonstrate significant changes in this test. The measures of WM (Corsi test) and tonic attention (RTA) did not change significantly with the QET-based intervention.
Conclusion: The study demonstrated that the QET protocol, which includes instructions and a video demonstration to optimize eye fixation on a target during aiming tasks, is acceptable and usable for children with ADHD. Overall, a short-term, 5-week visuomotor training intervention based on the quiet eye paradigm was shown to be effective in improving inhibitory control and focused visual attention, but not visuospatial WM and intrinsic attention in 9-12-year-old children with inattentive or combined ADHD.

Background: Noseband adjustment should avoid discomfort and allow some jaw movement.
Objectives: To determine pressure beneath a cavesson noseband at five tightness levels during standing and chewing. It was hypothesised that increased noseband tightness is associated with increases in nasal and mandibular pressures while standing and chewing, accompanied by increases in eye temperature and blink rate.

Purpose: Chronic anterior uveitis (CAU) often requires suppressive therapy, which has potential side effects including cataract, ocular hypertension, and increased risk of infection. No remittive therapy is currently available; however, several studies have demonstrated an association between low 25-hydroxy Vitamin D (25OHD) levels and either uveitis incidence or uveitis disease activity. This study investigates the potential of Vitamin D supplementation as a remittive treatment for CAU.

To our knowledge, this is the first report of anterior segment ischaemia after PreserFlo Micro-Shunt insertion surgery. Our patient developed anterior chamber (AC) activity and keratic precipitates 1 week after surgery. Five weeks after surgery, examination revealed a shallow AC, a distorted pupil with posterior synechiae and surface iris neovascularisation.

Gastroesophageal refluxes (GERs) are universal in newborns and may induce deleterious consequences, especially in preemies. We have previously shown that nasal continuous positive airway pressure (nCPAP) inhibits GERs in full-term lambs, complementing similar results in adult humans. The effect of high-flow nasal cannula (HFNC) on GERs, however, remains unknown.
