Abstract
Purpose To report the long-term follow-up results of posterior segment intraocular foreign body (IOFB) removal in children and to determine the prognostic factors for visual outcome. Methods Design: retrospective, noncomparative, interventional case series; a single tertiary care center study. Participants or samples: eleven eyes (11 patients) under 16 years of age with posterior segment IOFB injuries from May 2014 to November 2017. Main outcome measures: clinical features of injury, visual acuity, and complications. Results The mean age was 6.8 years, and the mean follow-up was 20.2 months. The main IOFB sources were accidental penetration of the eye by materials in the playground (6 cases) or by pencil lead at school (4 cases). The mean IOFB size was 3.8 (range 1–6) mm. At the last visit, the visual acuities were 20/40 or better in 40.0% of patients and better than 20/200 in 70.0%. Poor visual outcome was correlated with intraoperative rhegmatogenous retinal detachment (P=0.0083). Postoperative complications included elevated transient intraocular pressure, retinal redetachment, and secondary glaucoma. Conclusions The clinical features of pediatric posterior segment IOFBs suggest insufficient awareness of such injuries both on the playground and at school. Visual outcomes from surgical treatment were relatively favorable in this series.
Highlights
Ocular trauma is a leading cause of noncongenital monocular blindness in children, and it imposes a significant economic burden on society [1]
Data Collection. is was a retrospective study designed to assess the characteristics and surgical outcomes of posterior segment intraocular foreign body (IOFB) injuries in children and possible prognostic factors for visual outcome. e posterior segment is the back two-thirds of the eye that includes the vitreous, retina, choroid, and optic nerve
Inclusion criteria were consecutive patients aged less than 16 years who were admitted to the Eye, Ear, Nose and roat Hospital between January 2014 and December 2017 for posterior segment IOFB injuries
Summary
Ocular trauma is a leading cause of noncongenital monocular blindness in children, and it imposes a significant economic burden on society [1]. Intraocular foreign bodies (IOFBs) account for approximately onethird of open globe injuries and most commonly affect the posterior segment of the eye [2, 3]. E most common IOFB is metallic pieces produced from hammering. Foreign body injuries are common in children [4]; there are few reports of IOFBs in patients aged < 16 years. We report the clinical features and surgical outcomes in consecutive pediatric patients with posterior segment IOFBs who visited the Eye, Ear, Nose and roat Hospital of Fudan University, the largest tertiary referral eye center in East China that handles almost all IOFB cases in this region
