Risk Factors for Endophthalmitis and Retinal Detachment with Retained Intraocular Foreign Bodies

Abstract EN

Purpose.

To analyze risk factors for endophthalmitis and retinal detachment (RD) in patients with retained intraocular foreign bodies (IOFBs).

Design.

A retrospective, interventional, consecutive case series.

Participants.

All patients treated at Bascom Palmer Eye Institute for traumatic IOFBs between 1999 and 2008.

Methods.

Analysis of visual outcome, mechanism of injury, management, and postoperative course.

Results.

108 eyes with IOFBs were identified.

Endophthalmitis occurred in 7 eyes (6.4%) at presentation, and risk was higher with vegetable matter exposure (P=0.003).

All eyes with posterior segment IOFBs received intravitreal antibiotics and there were no cases of endophthalmitis after initial management.

RD was identified in 6 of 108 eyes (5.5%) at presentation.

Risk factors were entry more than 5 mm behind the limbus (P<0.001) and posterior segment IOFB (P=0.028).

Postoperative RD occurred in 11 of 102 eyes (10.7%).

Risk factors for postoperative RD were preoperative endophthalmitis (P=0.001), posterior segment IOFB (P=0.008), and retinal impact sites (P=0.028).

Conclusions.

Risk factors for endophthalmitis included vegetable matter exposure and delay to initial management.

Risk factors for RD were posterior entry site, posterior segment IOFB, endophthalmitis, and retinal impact sites.

No eyes developed endophthalmitis after presentation.
