Association between visual reaction time and batting, fielding, and earned run averages among players of the Southern Baseball League.

BACKGROUND: This study was performed to investigate the relationship between vision reaction time (VRT) and batting, fielding, and pitching skill in baseball. METHODS: A vision screening of 213 professional baseball players in the Southern Baseball League was performed, and the visual reaction times of these players were determined. Official Southern Baseball League statistics were consulted to obtain the players' batting average, fielding average, and earned run average. RESULTS: The mean visual reaction time for all players was 239 msec. There was no significant association between mean VRT and age or race. The mean VRT for dominant eyes was not significantly different from the mean VRT for nondominant eyes. For the 92 players who batted at least 100 times, an association was found between mean VRT and batting average (p = 0.017). For the 168 fielders in the league playing at least 20 games, no statistically significant association was found between mean VRT and fielding average. Similarly, no association was found between mean VRT and earned run average for the B8 pitchers who had participated in more than 20 games. CONCLUSIONS: An association was found between visual reaction time and batting skill in baseball. No association was found between visual reaction time and fielding or pitching skill.

Release of contact lens prescriptions: an update.

BACKGROUND: The release of contact lens prescriptions to patients is a clinicolegal issue of importance to optometrists. Legal obligations to release contact lens prescriptions are created by state optometry statute or optometry board rule or regulation. METHODS: State statutes and optometry board rules or regulations that pertain to contact lens prescription release requirements are reviewed. RESULTS: There are 22 states in which statutes or board rules or regulations require optometrists to provide prescriptions after patients have been fitted with contact lenses. In 29 states, the minimum elements of a contact lens prescription have been established. Optometrists in these states must understand and comply with prescription release requirements. CONCLUSIONS: To minimize misunderstandings and conflicts with patients, optometrists in jurisdictions without contact lens prescription release requirements should establish an office policy for the release of prescriptions and communicate this policy in writing to patients. To minimize the likelihood of injury to patients, contact lens prescriptions should be as complete as possible, thereby ensuring that lenses obtained from a third party dispenser will provide optimum acuity, comfort, and physiological response.

Glaucoma--a clinicolegal review.

BACKGROUND: Glaucoma is a leading cause of professional liability claims involving eye care practitioners. Reasons for litigation include the severe loss of vision that can result if the disease goes undetected and the variety of legal theories-breach of informed consent, negligence, and product liability-under which a practitioner may be held liable. METHODS: Leading cases and claims are reviewed to describe the variety of clinical situations in which glaucoma-related lawsuits have been successfully alleged. RESULTS: Eye care practitioners are most likely to be charged with failure to diagnose open-angle glaucoma, but failure to warn patients of suspicious findings and adverse effects of antiglaucoma medications are also significant causes of liability claims.

Liability for pediatric care.

Liability claims involving eye care for pediatric patients may constitute as much as 20% of claims against optometrists, with the most common sources of litigation being failure to detect tumors affecting the visual system, improper diagnosis and management of binocular vision disorders, and injuries from shattered spectacle lenses. Claims for pediatric patients tend to allege large damages, partially because of the significant effect exerted by lifelong vision impairment or loss of vision.

Release of spectacle prescriptions: an update.

BACKGROUND: Due to the provisions of the Federal Trade Commission's prescription release rule, the patients of optometrists are entitled to a copy of the spectacle prescription following the examination. METHODS: The FTC rule and provisions of various state laws that regulate the release of information from medical records have been reviewed to determine the specific legal requirements that govern the release of spectacle prescriptions. RESULTS: Although the FTC rule does not require specific information to be included in a spectacle prescription, in 19 states specific information is required, and optometrists in all states should include such additional information as they believe will be necessary to ensure that patients receive the appropriate spectacles from a third-party dispenser. In addition, the laws of 29 states require optometrists to release copies or information from patient records on request from the patient, and in 3 states optometry practice acts or board rules require the release of copies of the spectacle prescription, thereby expanding the duty to patients beyond that required by the FTC rule. In states that do not have statutory provisions, court rulings must be consulted to determine the extent of an optometrist's obligation to provide prescription information from records to patients. CONCLUSIONS: These legal obligations should be observed when providing spectacle prescriptions or responding to requests for prescription information.
