Abstract

Purpose To investigate the incidence and risk factors of intraocular foreign body- (IOFB-) related endophthalmitis. Methods A total of 1701 patients diagnosed with IOFB between January 1, 2005 and June 30, 2015 were included. Two groups of patients were defined according to the presence or absence of endophthalmitis, and a comparison of personal information, IOFB characteristics, and wound location were performed. Results In total, 279 patients (16.4%) developed endophthalmitis, older age (P=0.01) was a risk factor. IOFBs retained in the crystal lens or wall of the eyeball conferred lower risks (P=0.01 and 0.04, respectively) compared to the vitreous chamber. The coexistence of different IOFB types and plant IOFBs conferred higher risks (P=0.02 and 0.03, respectively), while glass/plastic IOFBs conferred a lower risk (P=0.03) compared to metallic IOFBs. Conclusions Age, IOFB locations, and types were related to development of endophthalmitis, while IOFB number, size, or timing of primary repairs was not related.

Highlights

Retained intraocular foreign body (IOFB) occurs in 18%– 41% of ocular trauma cases, leading to a wide range of ocular pathologies and vision outcomes [1]
Endophthalmitis has been included in the Ocular Trauma Score as an indicator for poor visual prognosis [2]. e prevalence of traumatic endophthalmitis has been reported to occur in approximately 4% to 8% of cases and may be higher at 6.9% to 30% in IOFB injuries [3]
Limited information is available in Asian populations regarding IOFB and associated endophthalmitis. us, the purposes of our study were to (1) assess the incidence of intraocular foreign body- (IOFB-)related endophthalmitis in a Chinese population and (2) relate the IOFB characteristics, including number, type, size, location, and wound location and time of primary repair, to the development of endophthalmitis

Summary

Introduction

Retained intraocular foreign body (IOFB) occurs in 18%– 41% of ocular trauma cases, leading to a wide range of ocular pathologies and vision outcomes [1]. Several studies reported that nonmetallic IOFBs had a higher risk of endophthalmitis compared to metallic IOFBs [5, 6].
