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.

Self-reported dry eyes and diabetic history.

Purpose: Dry eyes and diabetes have been linked in previous studies. However, the connection between a family history of diabetes and self-reported dry eyes needs to be explored. Patients with self-reported dry eyes were screened for self-reported diabetes or a family history of diabetes.

Validity of fluorexon disodium versus sodium fluorescein for use in Goldmann tonometry.

Purpose: To evaluate the safety, validity, and comfort of 0.35% fluorexon disodium and 0.4% benoxinate (Flura-Safe) compared with the gold standard of 0.

Accommodative insufficiency is the primary source of symptoms in children diagnosed with convergence insufficiency.

Purpose: Accommodative insufficiency (AI) and convergence insufficiency (CI) have been associated with similar symptomology and frequently present at the same time. The severity of symptomology in CI has been linked to the severity of the CI, suggesting a dose-dependent relationship. However, with increasing severity of CI also comes increased comorbidity of AI.

Color vision screening for individuals with intellectual disabilities: a comparison between the Neitz Test of Color Vision and Color Vision Testing Made Easy.

Background: The Neitz Test of Color Vision (Neitz) and Color Vision Testing Made Easy(trade mark) (CVTME) were compared to determine which test was more effective in evaluating patients with intellectual disability (i.e., mental retardation) and developmental delay.

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.

Developmental Eye Movement Test: reliability and symptomatology.

Background: The Developmental Eye Movement Test (DEM) is a widely used visual skill test, especially in the context of a vision therapy evaluation. It is intended to diagnose oculomotor dysfunction (OMD) and can also identify deficient rapid automatized naming. As such, its reliability and associated symptomatology are important.

Prevalence and severity of symptomatic dry eyes in Hispanics.

Purpose: Past studies have not addressed the prevalence of dry eyes in the growing US Hispanic population. 463 Hispanic patients were screened in an optometric practice located in Southern California.

Methods: A single symptom variable of self-assessed ocular dryness was used to categorize patients.

Ocular and systemic findings and their correlation with hemodynamically significant carotid artery stenosis: a retrospective study.

Background: Optometrists often encounter patients with ocular signs and/or symptoms suggestive of carotid artery disease, but criteria for eye care practitioners concerning when to order carotid studies are not well established. A retrospective study in an optometry clinic was performed to determine if certain ocular findings and associated systemic risk factors were associated with hemodynamically significant carotid artery stenosis (HSCAS).

Methods: A retrospective analysis was performed on all patients examined in the optometry clinic at the Sepulveda Ambulatory Care Center from January 1, 1998 through December 31, 1999 to identify all patients who had carotid studies ordered.
