Abstract
Introduction This study aims to delineate the etiology and prevalence of isolated pathogens, along with the clinical characteristics of endophthalmitis patients over a 9-year period at hospital in Southwest of China. Additionally, we investigating the metabolic and cellular processes related to environmental factors may offer novel insights into endophthalmitis. Methods We analyzed data pertaining to endophthalmitis patients treated at the Affiliated Hospital of Yunnan University from 2015 to 2023. According to our clinical data, we conducted an experiment based on transcriptomics and metabolomics analysis to verify whether environmental factors affect behavior of S. epidermidis by culturating S. epidermidis under oxic and microoxic condition. Results In this study, 2,712 fungi or bacteria strains have been analyzed, gram-positive bacteria constituted 65.08%, with S. epidermidis being the most predominant species (25.55%). Ophthalmic trauma was the primary pathogenic factor for S. epidermidis ocular infections. Regarding fluoroquinolones, S. epidermidis exhibited the higher resistance rate to levofloxacin than moxifloxacin. Moreover, our investigation revealed that S. epidermidis in microoxic environment increase in energy metabolism, amino acid metabolism, and membrane transport. Conclusion Our findings underscore the significance of S. epidermidis as a crucial pathogen responsible for infectious endophthalmitis. It is crucial to exercise vigilance when considering Levofloxacin as the first-line drug for empiric endophthalmitis treatment. The metabolites alteration observed during the commensal-to-pathogen conversion under microoxic condition serve as a pivotal environmental signal contributing to S. epidermidis metabolism remodeling, toward more pathogenic state.

Carbohydr Polym 2024; 331:121854. [PMID: 38388052 DOI: 10.1016/j.carbpol.2024.121854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 01/18/2024] [Accepted: 01/20/2024] [Indexed: 02/24/2024]
Abstract
Open globe injuries (OGIs) demand immediate attention to prevent further complications and improve vision prognosis. Herein, we developed a thermo/photo dual-crosslinking injectable hydrogel, HBC_m_Arg, for rapidly sealing OGIs in emergency ophthalmic cases. HBC_m_Arg was prepared with arginine and methacrylic anhydride modified hydroxybutyl chitosan (HBC). HBC_m_Arg was initially in liquid form at 25 °C, enabling easy injection at the injury site. After reaching the ocular surface temperature, it underwent reversible heat-induced gelation to achieve in situ transformation. Further, HBC_m_Arg was capable of rapid photocrosslinking under UV light, forming a dual network structure to bolster mechanical strength, thereby facilitating effective OGI closure. Biocompatibility assessments, including in vitro studies with three ocular cell types and in vivo experiments on rabbit eyes, confirmed the safety profile of HBC_m_Arg. Ex vivo and in vivo burst pressure tests demonstrated the hydrogel's ability to promptly restore intraocular pressure and withstand elevated pressures, underscoring its potential for OGI stabilization. Additionally, the suitable degradation of HBC_m_Arg within ocular tissues, coupled with its stability in ex vivo assessments, presented a delicate balance between stability and biodegradability. In conclusion, HBC_m_Arg holds promise for improving emergency ophthalmic care by providing a rapid, effective, and safe way to seal OGIs in critical situations.

Abstract
Open-globe injuries (OGI) can lead to significant visual impairment. The Ocular Trauma Score (OTS) is the most widely recognized tool for predicting visual outcomes. This review aimed to identify prognostic factors and assess the effectiveness of the OTS in predicting visual outcomes. Twenty-one articles published on PubMed and Google Scholar were analyzed. Initial visual acuity and the zone of injury were found to be the most significant prognostic factors for OGI. Other significant prognostic factors include retinal detachment/involvement, relative afferent pupillary defect, vitreous hemorrhage, vitreous prolapse, type of injury, hyphema, lens involvement, and duration from incidence of OGI to vitrectomy. Of the 21 studies evaluated, 11 investigated the effectiveness of OTS. Four studies concluded that OTS was effective overall, while six studies suggested that it was only useful in certain OGI categories. Thus, there is a need for further research to develop an optimized ocular trauma prognosticating system.

Open Globe Injury in a Tertiary Hospital of Northern Thailand: No Vision Survival and Ocular Trauma Score. Clin Ophthalmol 2023; 17:365-373.

Abstract
Purpose To determine characteristics and factors associated with no vision survival (included no light perception, enucleation, and evisceration) following open globe injury (OGI) and to correlate the proportion of final vision to predictive values of ocular trauma score (OTS). Patients and Methods The medical records of consecutive patients diagnosed as OGI between January 2015 and December 2020 were retrospectively reviewed. Data collected included demographics, mechanisms and modes of injuries, ophthalmic presentations, managements, and visual outcomes at the final visit. Results Three hundred and seventy-one patients with a mean (standard deviation, SD) age of 44.0 (17.4) years were included. Male with workplace injury was the most frequent scenario. High-velocity metallic objects were the predominant causative materials. Following treatments, fifty-six eyes (14.9%) obtained no vision survival. Factors associated with no vision survival following OGI were low presenting vision, globe perforation, larger wound, presence of relative afferent pupillary defect, retinal detachment, and vitreous hemorrhage. Compared to OTS predictive values, eyes in OTS categories 1 and 2 had a lower proportion of no vision survival. Conclusion This study identified the importance of workplace injuries. Overall, there were comparable final visions between OTS and this study. However, a reduced proportion of no vision survival among severely injured eyes signifies the challenges of OGI management.

Abstract
Purpose To determine the prevalence of different types of ocular trauma and their relationship with some factors in the elderly population. Methods The present population-based cross-sectional study was conducted on the elderly population aged 60 years and above in Tehran, Iran, using multi-stage stratified random cluster sampling in 2019. After selecting the samples and their participation in the study, demographic information and history of ocular trauma were obtained through an interview. Psychological evaluation was performed using the Goldberg's 28-question General Health Questionnaire. All study participants underwent optometric and ophthalmological examinations. Results Three thousand three hundred and ten people participated in the study (response rate: 87.3%). Of these, 1912 individuals (57.8%) were female and the mean age of individuals was 68.25 ± 6.55 (from 60 to 97) years. 7.46% (95% confidence interval [CI]: 6.51-8.41) of the study participants reported a history of ocular trauma. Blunt and chemical traumas were the most and the least common types of ocular trauma, respectively (5.72% and 0.16%). 3.93% of cases visited an ophthalmologist for ocular trauma, 1.67% reported a history of hospitalization, and 1.47% underwent surgery. The prevalence of visual impairment in individuals with a history of ocular trauma was 12.53%. Visual impairment was more prevalent in people with a history of ocular trauma than those without a history of ocular trauma (P < 0.05). History of ocular trauma was only significantly related to low education level (odds ratio = 0.63, 95% CI = 0.40-0.99). Participants with a history of ocular trauma had more anxiety and higher mean psychological distress score than those without a history of ocular trauma (P = 0.035). Conclusions The development of preventive programs against the occurrence of ocular trauma can play an important role in reducing the psychological damage of affected patients while reducing visual disorders. These interventions should be especially considered in groups with a lower education level.
