The Role of Computed Tomography in the Immediate Workup of Open Globe Injury

Abstract

Purpose Immediate primary closure is indicated in cases of traumatic open globe injury. Orbital computed tomography (CT) is performed prior to primary closure in order to rule out possible intraocular foreign bodies (IOFB) and/or damage to adjacent extraocular as well as intraocular structures. The aim of the present study is to evaluate the yield of orbital CT scan in immediate clinical decision-making in cases of open globe injury. Methods All cases of open globe injury treated in our institute during a 10-year period were reviewed. All underwent a CT scan before any surgical intervention, regardless of trauma severity. The influence of the CT scan results on decisions regarding the immediate treatment of the open globe injury was analyzed. Results A total of 125 cases of open globe injury were included in the present study. In none of these cases did the CT scan results have any influence on immediate treatment. The CT scan results did influence decisions that were made after the immediate operative stage. Conclusions Computed tomography scan has limited value in immediate clinical decision-making in cases of open globe injury scheduled for primary closure. While not crucial prior to the initial procedure, it is of value in managing the case during the following few days as well as later on. This study suggests that a CT scan performed after the initial globe exploration and suturing procedure is a valid alternative to stalling the definite globe suturing process until a CT scan is obtained and interpreted.
