The quiet eye gaze behavior of 4 near-expert and 4 expert baseball umpires who called balls and strikes in simulated pitch-hit situations was assessed with a mobile eye cornea tracker system. Statistical analyses of the umpires' gaze behavior (fixation/pursuit tracking, saccades, and blinks)--onset, duration, offset, and frequency--were performed between and within 4 stages (pitcher's preparation, pitcher's delivery, ball in flight, and umpire call) by umpire's skill level. The results indicated that the quiet eye of expert umpires at onset of the pitcher's release point occurred earlier and was longer in duration than near-expert umpires. Expert expert umpires. The area outside the pitcher's ball release point may be the key environment cue for the behind-the-plate umpire.

Objective: Periorbital necrotizing soft tissue infection (NSTI) is a rare entity caused either by polymicrobial infection (type 1) or Streptococcus pyogenes and/or Staphylococcus species (type 2). A high level of clinical suspicion is necessary to make the diagnosis. We present 3 cases of NSTI illustrating our diagnostic and therapeutic approach.

Introduction: Peripheral intravenous cannulation (PIVC) is a common and complex procedure with low first-attempt success rates, causing patient suffering and increased healthcare costs. Quiet Eye (QE) training, a gaze-focused approach, has shown promise in improving procedural PIVC skills. We will examine the effectiveness of traditional technical training (TT) and QE training (QET) on student nurse PIVC performance.

Speechreading-gathering speech information from talkers' faces-supports speech perception when speech acoustics are degraded. Benefitting from speechreading, however, requires listeners to visually fixate talkers during face-to-face interactions. The purpose of this study is to test the hypothesis that preschool-aged children allocate their eye gaze to a talker when speech acoustics are degraded.

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.
Vitamin D Supplementation and Remission from Chronic Anterior Uveitis.

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.
