Visual Performance and Sports: A Scoping Review.

Vision is central to success in nearly all sports, and there is an emerging body of research investigating the links between visual abilities and athletic performance. This preregistered scoping review seeks to clarify the topics of study, methodologies used, populations under investigation, researchers, and disciplines driving this field. Systematic searches of English-language articles were conducted in PubMed and Web of Science, with additional literature identified through bibliographic searches.

Review: Vision and On-field Performance: A Critical Review of Visual Assessment and Training Studies with Athletes.

Sports vision is an emerging field that seeks to establish the relationships between visual function and sports performance. Here we provide the first critical review of empirical studies that attempt to link visual assessments and vision training to competitive game performance.Vision is essential to producing controlled movement, and therefore, it is intuitive that better visual abilities should relate to better sporting performance.

The Uses of Vision Data in Selecting Players for the Major League Baseball Draft.

Significance: This report illustrates the potential uses of vision data in helping teams select players during the draft.

Purpose: Visual performance has gradually gained recognition in baseball as a tool that can optimize on-field performance. It also may be useful in player development programs that gradually move players toward the major league.

The Effect of Visual Function on the Batting Performance of Professional Baseball Players.

This report evaluates the role of the combined visual abilities of acuity, contrast sensitivity and presentation time on plate discipline and baseball batting performance. A visual function test (EVTS) was performed on 585 professional baseball players. The results were compared to several common plate-discipline measures.

The Hand-eye Coordination of Professional Baseball Players: The Relationship to Batting.

Significance: A visuomotor skill (eye-hand visual-motor reaction time [EH-VMRT]) important for baseball performance is described. Eye-hand visual-motor reaction time represents the integration of visual information, perceptually based decisions, and motor movements to accomplish a specific task. The speed at which this occurs depends on many factors, some visual, some perceptual, and some motor related.

Case Report: Use of Sports and Performance Vision Training to Benefit a Low Vision Patient's Function.

Significance: Despite our inability to attenuate the course of many ocular diseases that can ultimately lead to loss or significantly decreased visual function, this report describes a potential technique to aid such patients in maximizing the use of the vision that remains.

Purpose: The aim of this study was to demonstrate the applicability of utilizing sports vision training to improve objective and subjective visuomotor function in a low vision patient.

Case Report: A 37-year-old woman with Usher syndrome presented with reduced central visual acuity and visual field.

The Refractive Error of Professional Baseball Players.

Purpose: High levels of visual acuity are required to hit a baseball effectively. Research has shown that any decrease in vision is likely caused by low-order optical aberrations. This study is designed to validate the SVOne autorefractor, and describe the amount and type, of low-order optical aberrations present in a large cohort of professional baseball players.

Thoughts on ocular dominance-is it actually a preference?

Background: Ocular dominance has been studied for many years, and there have been many attempts to correlate eye dominance with athletic performance. Although many reports have failed to show a correlation, some reports have shown a relationship between sports performance and eye dominance.

Methods: This report reviews some of those studies and the tests of eye dominance used in the reports.

The visual function of olympic-level athletes-an initial report.

Objective: To describe the visual functions of Olympic-level athletes and begin to describe any differences between sports.

Methods: A commercially available testing system was used to evaluate 157 Olympic-level athletes. These sports vision evaluations were therefore performed under standardized conditions.

Optic neuropathy in a child with alopecia.

A 4-year-old boy develops an insidious optic neuropathy, of unknown etiology, followed shortly thereafter by a focal patch of hair loss (biopsy proven-alopecia areata) on the back of his head. The temporal aspects of these findings suggest a common, likely inflammatory, etiology.

Optical aberrations in professional baseball players.

Purpose: To determine the presence, type, and size of optical higher-order aberrations (HOAs) in professional athletes with superior visual acuity and to compare them with those in an age-matched population of nonathletes.

Setting: Vero Beach and Fort Myers, Florida, USA.

Methods: Players from 2 professional baseball teams were studied.

Effects of head tilt on stereopsis.

Purpose: Depth perception is an important part of many everyday tasks such as driving, catching a ball, and threading a needle. Binocular cues such as horizontal retinal image disparity (HRID) are significant cues to depth and play an important role in overall depth perception. Stereoscopic threshold (stereoacuity) is directly proportional to the interpupillary distance (IPD).

A symptom survey and quality of life questionnaire for nasolacrimal duct obstruction in children.

Purpose: To develop and validate a new parental questionnaire addressing symptoms and health-related quality of life (HRQL) in childhood nasolacrimal duct obstruction (NLDO).

Design: Cross-sectional study.

Participants: Children ages 6 to younger than 48 months with and without clinical signs of NLDO.

The effect of laser refractive surgery on the on-field performance of professional baseball players.

Background: The aim of this study was to determine the effect of laser refractive surgery on the offensive performance of professional baseball players.

Methods: Extensive search of the public media was conducted to determine which major league baseball players had undergone laser refractive surgery and when the procedure was performed. Baseball performance data were then used to determine presurgery and postsurgery baseball performance averages.
