Background: We hypothesize that creation of a structured curriculum in neuro-ophthalmology principles might improve self-rated learner satisfaction and knowledge base of National Football League (NFL) game officials. Our initial objective is to create the said curriculum in coordination with game official experts and staff at the NFL to increase levels of understanding of neuro-ophthalmology principles. We reviewed the prior published literature on applicable neuro-ophthalmic principles in professional sports. Major neuro-ophthalmic principles reviewed include both the efferent (e.g., saccadic and pursuit eye movements and vestibulo-ocular reflex) and afferent (visual field, dynamic visual acuity during body movement, and selective attention deficits).

Methods: A 6-question survey pertaining to levels of understanding, future applicability, relevance, satisfaction, and interest in additional training was then given to 26 individuals before and after a lecture given by Dr. Andrew Lee in Plano, TX. The primary outcome measure was the creation of the curriculum followed by real-world testing for face and content validity and ending with a self-rated assessment.

Results: Twenty-one individuals completed the prelecture and postlecture survey out of 26 individuals who attended. Prelecture means for the level of understanding of oculomotor terms and the likelihood of using said terms were 3.4 and 3.2, respectively. Postlecture means were 8.9 and 8.8, respectively. The lecture was rated 9.2 of 10 for relevance to coaching and teaching officials, and individuals rated their interest in further content as 9.4 of 10.

Conclusions: This study found that NFL game officials are interested in learning more about the science behind play-calling in terms of neuro-ophthalmology principles and practices. In addition, from our pilot survey, it is evident that even one lecture can improve participants' level of understanding and likelihood of learning more about neuro-ophthalmic principles.

Background: Optometrists are often the first providers to evaluate patients with acute vision loss and are often the first to diagnose a central retinal artery occlusion (CRAO). How quickly these patients present to the optometrist, are diagnosed, and referred for evaluation are major factors influencing the possibility of acute therapeutic intervention. Our aim was to survey the U.S. optometric community to determine current optometric practice patterns for management of CRAO.

Methods: An anonymous seven-question survey was emailed in 2020 to the 5,101 members of the American Academy of Optometry and the 26,502 members of the American Optometric Association.

Results: Of 31,603 optometrists who were sent the survey, 1,926 responded (6.1%). Most respondents (1,392/1,919, 72.5%) worked in an optometry-predominant outpatient clinic and were less than 30 minutes from a certified stroke center (1,481/1,923, 77.0%). Ninety-eight percent (1,884/1,922) of respondents had diagnosed less than 5 CRAOs in the previous year, and 1,000/1,922 (52.0%) had not diagnosed a CRAO in the prior year. Of the optometrists who diagnosed at least one CRAO in the previous year, 661/922 (71.7%) evaluated these patients more than 4 hours after the onset of vision loss. Optometrists who diagnosed a CRAO or branch retinal artery occlusion referred patients to an emergency department (ED) affiliated with a certified stroke center (844/1,917, 44.0%), an outpatient ophthalmology clinic (764/1,917, 39.9%), an ED without a stroke center (250/1,917, 13.0%), an outpatient neurology clinic (20/1,917, 1.0%), or other (39/1,917, 2.0%); most (22/39, 56.4%) who responded "other" would refer to a primary care physician.

Conclusions: Optometrists are likely the first providers to evaluate patients with acute vision loss, including from a retinal artery occlusion. However, only 6.1% of optometrists responded to our survey despite 2 reminder emails, likely reflecting the lack of exposure to acute retinal artery occlusions, and a potential lack of interest of optometrists in participating in research. Of the optometrists who reported evaluating a CRAO in the previous year, less than 29% saw the patient within 4 hours of vision loss. In addition, a large portion of optometrists are referring acute CRAO patients to outpatient ophthalmology clinics, delaying appropriate acute management. Therefore, it is imperative that optometrists and ophthalmologists are educated to view acute retinal arterial ischemia as an acute stroke and urgently refer these patients to an ED affiliated with a stroke center. The delay in patient presentation and these referral patterns make future clinical trials for acute CRAO challenging.

Background: To investigate whether recovery from or development of metabolic syndrome (MetS) in a population is associated with an altered risk for ocular motor cranial nerve palsy (CNP).

Methods: This cohort study included 4,233,273 adults without a history of ocular motor cranial nerve palsy (ocular motor CNP) who underwent 2 consecutive biennial health screenings provided by the Korean National Health Insurance System between 2009 and 2011. They were followed up until December 31, 2018. Participants were categorized into a MetS-free, MetS-developed, MetS-recovered, or MetS-chronic group. A multivariable Cox proportional hazard regression model was used. Model 3 was adjusted for age, sex, smoking status, alcohol consumption, and physical activity.

Results: Compared with the MetS-free group, the MetS-chronic group had the highest risk of ocular motor CNP (hazard ratio [HR]: 1.424; 95% confidential interval [CI]: 1.294-1.567, Model 3), followed by the MetS-developed group (HR: 1.198, 95% CI: 1.069-1.343), and the MetS-recovered group (HR: 1.168, 95% CI: 1.026-1.311) after adjusting for potential confounders. The hazard ratio of ocular motor CNP in men with chronic MetS was 1.566 (95% CI, 1.394-1.761) while that of women with chronic MetS was 1.191 (95% CI, 1.005-1.411). Among age groups, those in their 30s and 40s showed the highest association between dynamic MetS status and ocular motor CNP.

Conclusions: In our study, recovering from MetS was associated with a reduced risk of ocular motor CNP compared with chronic MetS, suggesting that ocular motor CNP risk could be managed by changing MetS status.
