Abstract

Introduction: This study aimed to assess the impact of early vitrectomy on visual outcomes 1 month after surgery in patients with open ocular trauma. Methods: A historical cohort study analyzed 180 eyes from patients who underwent primary vitrectomy between 2017 and 2023. Data collected included the Birmingham Eye Trauma Terminology for injury assessment, the Ocular Trauma Score (OTS) for clinical findings, and visual acuity measured on the logMAR scale. Visual outcomes were compared between early surgery (within 4 days) and delayed surgery (after 4 days) using a linear mixed-effects model with a random effect for the surgeries performed. Results: Most cases had an OTS of 1 and underwent pars plana vitrectomy (PPV) and phacoemulsification (PHACO). OTS 2 cases underwent PPV with PHACO and air tamponade, while OTS 3-4 cases involved additional tamponades. One month after surgery, OTS 2 eyes with early surgery showed significantly better visual outcomes (p = 0.003). There were no statistically significant differences in complications regarding the time of surgery. Conclusion: Early vitrectomy, particularly within 4 days of injury, seems to improve both functional and anatomical outcomes in patients with severe open ocular trauma, especially for OTS 2.
