The ability to make on-field, split-second decisions is critical for National Football League (NFL) game officials. Multiple principles in visual function are critical for accuracy and precision of these play calls, including foveation time and unobstructed line of sight, static visual acuity, dynamic visual acuity, vestibulo-ocular reflex, and sufficient visual field. Prior research has shown that a standardized curriculum in these neuro-ophthalmic principles have demonstrated validity and self-rated improvements in understanding, confidence, and likelihood of future utilization by NFL game officials to maximize visual performance during officiating. Virtual reality technology may also be able to help optimize understandings of specific neuro-ophthalmic principles and simulate real-life gameplay. Personal communication between authors and NFL officials and leadership have indicated that there is high interest in 3D virtual on-field training for NFL officiating. In this manuscript, we review the current and past research in this space regarding a neuro-ophthalmic curriculum for NFL officials. We then provide an overview our current visualization engineering process in taking real-life NFL gameplay 2D data and creating 3D environments for virtual reality gameplay training for football officials to practice plays that highlight neuro-ophthalmic principles. We then review in-depth the physiology behind these principles and discuss strategies to implement these principles into virtual reality for football officiating.

In light of the potential effects of spaceflight on the anterior segment of the eye, there is a pressing need for anterior segment imaging to be available and accessible to monitor astronauts’ ocular health, including alterations to the cornea and lens. We aim to highlight the clinical basis and need for anterior segment imaging for astronauts. We explore the impacts of spaceflight-associated hazards, including microgravity and radiation, on astronauts’ risk of developing anterior segment pathology including risk of ocular trauma, infection, dry eye symptoms, cataracts, and possibly additional pathologies from increased radiation exposure. Such risks highlight the potential value that longitudinal assessment of anterior ocular structures would offer in future spaceflight missions. Specifically, anterior segment imaging would enable evaluations of corneal morphology, including longitudinal monitoring for microgravity-induced changes, and evaluation of interventions that aim to preserve anterior segment health during spaceflight. Lastly, non-invasive anterior segment imaging allows for unique insights into astronaut ocular health and can be performed routinely through modalities such as anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM). We discuss these modalities and their implications for astronaut health during future spaceflight.
