Abstract
Objective: This study aimed to investigate the etiology, pathogens, antibiotic susceptibility, treatments, and factors influencing the visual prognosis of pediatric post-traumatic endophthalmitis (PTE) to provide valuable insights for clinical diagnosis and treatment. Results: A total of 301 children were included, with 142 (47.2%) cultures yielding positive results. Gram-positive cocci were the predominant pathogens (71.1%), with high sensitivity to vancomycin (95.4%). Pars plana vitrectomy (PPV) was performed in 216 eyes (71.8%), with emergency or immediate vitrectomy within 24 h of hospitalization performed on 171 eyes (56.8%). The first intravitreal antibiotic injection, consisting of ceftazidime and norvancomycin, was administered to 248 patients (82.4%). The absence of retinal detachment (OR, 0.191; 95% CI, 0.065-0.560; p = 0.002), normal intraocular pressure (OR, 1.894; 95% CI, 1.151-3.117; p = 0.012), and no lens extraction (OR, 0.187; 95% CI, 0.069-0.504; p < 0.001) were found to be independent factors associated with better visual outcomes (BCVA) in pediatric PTE patients. Methods: A retrospective analysis was conducted on pediatric PTE patients treated between January 2012 and June 2022. Data were collected on clinical characteristics, causative pathogens, antibiotic sensitivity, treatments, and visual outcomes. Conclusions: Gram-positive cocci are the most common pathogens in pediatric PTE, with early vitrectomy and intravitreal ceftazidime and norvancomycin being the most effective treatments. Favorable visual outcomes are strongly associated with the absence of retinal detachment, normal intraocular pressure, and no lens extraction. These findings highlight the need for timely surgical and antimicrobial interventions tailored to each patient to improve visual prognosis.
