Background: Ocular trauma is one of the major threats of monocular blindness in children. The purpose of the study was to investigate the epidemiology, clinical characteristics and surgical outcomes of pediatric ocular trauma in southwest of China.
Methods: The medical records of all patients with ocular trauma under 12 years old receiving three-port pars plana vitrectomy (PPV) in Southwest Eye Hospital from January 2007 to December 2017 were retrospectively analyzed in this study. Data records included age, gender, cause, type and time of injury, initial and final visual acuity (VA), type and times of operation.
Results: This study included 122 eyes of 122 pediatric patients over a 11-year period. The mean age was 6.6 ± 3.2 years with a male-to-female ratio of 4.3:1. There were 100 (82%) open globe injuries (OGI) and 22 (18%) closed globe injuries. Of the open globe injuries, penetrating injury caused by sharp metal objects accounted for the highest percentage (70%). PPV could significantly improve VA in children with ocular trauma (P ˂ 0.01). In addition, the successful rate of PPV was not related with the age (P = 0.23) but significantly associated with intraocular tamponade (P < 0.05).
Conclusions: The most common predisposing factor of pediatric ocular trauma in southwest of China was sharp metal objects resulting in penetrating injury. In our study, gas tamponade for vitrectomy had the highest successful rate, followed by balanced salt solution (BSS) and silicone oil. Unlike the age and injury classification, the preoperative VA was a solid prognostic indicator of postoperative vision.
