“…As for PA in relation to VD, some studies were consistent with ours, which reported an increase of central VD after high-intensity interval training [19], whereas those of others were not [18, 20, 21]. However, prior research regarding the impact of exercise on VD mostly assessed short episodes of PA, thus hardly providing clues to the chronic effect of PA on vascular structure.…”

“…Similarly, Yalçın et al found a reduction in FAZ area of the deep capillary plexus after acute anaerobic exercise [17] while Pressler et al [10] reported a significantly greater arteriolar-to-venular ratio (i.e., larger arterioles and smaller venules) in marathon runners compared with their age-matched sedentary controls. In contrast, a recent cross-sectional study comparing the neurovascular structures between 30 adult athletes and 30 nonathletes detected an increased FAZ perimeter in nonathletes [18].…”

Introduction: We aimed to assess the association of physical activity (PA) with retinal thickness and vascular structure in an elderly Chinese population. Methods: This study enrolled 220 retirees aged 50 years and above from Tianjin University of Sport, China. PA data gathered through the International Physical Activity Questionnaires were computed for metabolic equivalent of task-minutes per week. All participants underwent full ophthalmic examination including optical coherence tomography angiography (OCTA). Multiple linear regression analyses were used to evaluate the association of PA with retinal thickness and vascular structure. Results: A high amount of total PA was associated with smaller size of foveal avascular zone (FAZ) (high vs. low: area, β=-0.04; circumference β=-0.14) and greater central vessel (VD) (β=1.04) and perfusion densities (PD) (β=0.02). For domain-specific PA, participants with high and moderate recreational PA levels were found to have greater central VDs and PDs. Non-leisure activities demonstrated negative relationship with FAZ perimeter ratio (moderate vs. low: β=-0.08; high vs. low: β=-0.13) and, counter-intuitively, negative relation with VDs measured at the inner (high vs. low: β=-0.98) and outer retinal layers (high vs. low: β=-0.38). Additionally, higher levels of total PA were related to increased macular fovea thickness and average thickness of retinal nerve fiber layer. Conclusions: High PA level, particularly recreational PA, was associated with smaller FAZ and greater VD and PD in senior adults. Non-leisure time PA might not confer the same health benefits as leisure time PA. Our data supports a possible protective role of recreational PA in the retina against microvascular changes.

“…They found that in the nonathlete group, there were significantly reduced vessel densities across many retinal microvascular structures [36]. In a review by Bryle et al ( 2022), the authors provided evidence from various studies about the benefits of physical activity in reducing the risk of developing DR and stated that less physically active diabetic patients showed increased blood flow in the retina on exertion [37]. In general, the pathogenesis of DR is primarily due to vascular abnormalities in the retina, yet choroidal abnormalities in the eye of patients with DR have also been found [38].…”

Substantial evidence highlights the association between physical inactivity and diabetes onset and complications. Little is known regarding the link between physical inactivity and diabetic retinopathy in terms of onset, progression, and severity. This review aims to investigate these associations and understand the underlying mechanisms behind these associations. Decreased sedentary times and the inclusion of more physical activity have been linked to the delayed onset and progression of diabetic retinopathy and less severe forms of said condition. Physical activity provides both protective and anti-inflammatory effects on the retina. Further research is needed to understand and elucidate the exact mechanisms by which lack of physical activity affects retinal health and the onset, progression, and severity of diabetic retinopathy.

Remarkable athletic feats often invoke questions from observers about how these achievements are possible. In baseball, softball, and cricket, how does a batter achieve the remarkable temporal and spatial accuracy in their swing necessary to successfully bat the ball, all while under severe timing constraints? How does a soccer player moving at full speed "thread the needle" with a perfectly placed pass between defenders? Sports are necessarily designed to test the limits of human abilities, and given the vital role of vision in sport, it is important to consider how visual abilities enable or constrain sports performance.The overarching topic in this feature issue is the role of vision in sports performance. This area is clearly of growing interest, with 73% (1985/2713) of the citations returned in PubMed for the search terms "sports" and "vision" occurring since 2010 (on May 1, 2021). As further evidence of the interest and enthusiasm for sports vision, the International Sports Vision Association was formed to advance the field of vision assessment and training for athletes, and the Journal of Sports and Performance Vision began publishing research articles on these topics in 2019. Because sports vision encompasses a wide array of subject matters, the sports vision literature is understandably disseminated throughout many diverse journals that may or may not be devoted solely to vision. These journals are centered around topics including vision science, cognition, kinesiology and biomechanics, sports science, neuroscience, learning, and both ocular and systemic clinical issues.The goal of this feature issue is to bring together studies that cover a variety of topical areas in sports vision. There are articles on vision assessments, vision correction and eye protection, cognitive-perceptual issues, vision training, concussion, and retinal physiology. Key questions for sports vision practitioners that are addressed in this feature issue include the following: what visual or vision-related attributes may underpin success in a particular sport, what cues are used by athletes to compete successfully in their sport, what visual assessments are best to measure an athlete's current level of development and to estimate his/her future potential, and which training methods and training environments (e.g., virtual or on-field) result in optimal transfer to athletic competitions. In keeping with the global reach of sports, the articles in this feature issue were contributed by authors from Australia,
