Visual system is a critical sensory system in humans and a vital component of the central nervous system, which is responsible for over 80% of external information acquisition.Visual function is a key indicator of overall health.With socioeconomic development, the public has higher expectations for eye health, shifting the focus of eye health initiatives from disease treatment to comprehensive public eye health.Key scientific challenges include how to effectively prevent, diagnose, and treat blindness and visual impairment at an early stage; how to enhance the overall visual quality of patients to ensure not just sight but clear and comfortable vision; and how to meet the public's diverse and multi-tiered eye health needs.Visual science is an interdisciplinary field exploring the development of the visual system, the mechanisms of vision, and brain-related perceptual, cognitive and behavioral processes involving sight.Prioritizing and advancing visual science research is of great significance for promoting comprehensive eye health and implementing the Healthy China Strategy.This article first outlines the concept and research significance of visual science.It then highlights the key scientific questions in visual science pertaining to several major eye diseases, such as myopia, amblyopia, cataract, fundus diseases, glaucoma, and corneal diseases, reviews the historical foundation of visual science research in China, selectively summarizes key achievements and ongoing progress in this field, analyzes the landscape and challenges faced by domestic research, and proposes, to this end, strategies to advance visual science in China.These recommendations are designed to promote visual science research in China and ultimately advance comprehensive eye health.

Objective:To investigate the risk factors of acute gastrointestinal failure in patients with traumatic brain injury(TBI).Methods:A retrospective analysis of 297 patients admitted to the Rugao Hospital Affiliated to Nantong University for traumatic brain injury from March 2018 to March 2020 was performed. Multivariate Logistic regression analysis was used to test the risk factors of acute gastrointestinal failure in patients with traumatic brain injury.Results:Of the 297 patients with TBI, 92 (30.98%) had acute gastrointestinal failure, of which 56 (18.86%) were acute gastrointestinal injury(AGI) Ⅲ and 36 (12.12%) were AGI Ⅳ. Multivariate Logistic regression analysis showed that female, low Glasgow Coma Scale (GCS) scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection were independent risk factors for acute gastrointestinal failure in TBI patients ( P<0.05). The length of ICU stay in the acute gastrointestinal failure group was significantly higher than that of the non-acute gastrointestinal failure group: (18.5 ± 2.6) d vs. (6.3 ± 1.2) d, and the incidence of good prognosis was significantly lower than that of the non-acute gastrointestinal failure group: 60.87%(56/92) vs. 80.49(165/205), the differences were statistically significant ( P<0.05). Conclusions:That female, low GCS scores, frontal lobe injury, abnormal serum sodium, lung infection and intracranial infection are independent risk factors for acute gastrointestinal failure in TBI patients
