Clinical analysis of posterior segment injury in left-behind children in China.

Background: We aimed to evaluate the severity and prognosis of posterior segment injury between left-behind children (LBC) and guarded children (NLBC).

Methods: A retrospective, controlled analysis of a case series was performed. Patients diagnosed with posterior segment injury in Department of vitreous and retinal, the Affiliated Ophthalmology and Otolaryngology Hospital of Fudan University were included in this study. Patients were divided into two groups, including LBC group (n = 48) and NLBC group (n = 44). All the children underwent 25G transconjunctival sutureless pars plana vitrectomy.

Results: Compared with NLBC, LBC had delayed treatment, worse baseline vision and visual prognosis, lower OTS rating, more times of vitrectomies, more complicated surgical procedures, and higher rate of lens removal and silicone oil tamponade.

Conclusions: Due to lack of care and delayed treatment, posterior segment ocular trauma in the LBC was more severe, more common complicated with infectious endophthalmitis, and had worse visual prognosis. It was urgent to enforce the guardianship in LBC.
