Lee, Lee, Shin, Lee, Jang, and Baek: Significant Intraocular Sequelae in Orbital Blunt Trauma and Their Association with Blowout Fracture

Abstract

Purpose

To investigate the frequency of significant intraocular sequelae (SIOS) in orbital blunt trauma and their association with blowout and facial bone fractures.

Methods

A retrospective survey consisting of 726 patients with orbital blunt trauma who visited Korea University Medical Center was performed. Patients were divided into three groups: blowout fracture only group (group 1), facial bone fracture group (nasal bone fracture, maxillary fracture, zygoma fracture without blowout fracture, group 2), and non-fracture group (group 3). SIOS (traumatic iridocyclitis, commotio retina, hyphema, retinal hemorrhage, eyeball rupture, vitreous hemorrhage, retinal detachment, lens dislocation, traumatic cataract) were surveyed in each group, and the association between the frequency of SIOS and the presence of blowout fracture or facial bone fracture was analyzed.

Results

The frequency of SIOS in the fracture groups was 83.8% in group 1 and 73.3% in group 2, which were both higher than the 67.9% in group 3, the non-fracture group (p = 0.000 by chi-square linear by linear association). Traumatic iridocyclitis and hyphema were also significantly higher in groups 1 and 2 than group 3 (p = 0.003, p = 0.008 by chi-square linear by linear association).

Conclusions

SIOS was found significantly more often in the fracture group than the group without fracture, although the frequency of severe SIOS was lower in the fracture group than the non-fracture group. The results from the present study could help in the treatment and management of patients with orbital blunt trauma.
