Posttraumatic intraocular pressure elevation and associated factors in patients with zone I open globe injuries
Abstract
Background: The object of this study was to determine factors that might be associated with intraocular pressure (IOP) elevation after anterior segment open globe injuries (zone I).
Methods: Data were obtained from the records of 68 patients who experienced zone I open globe injury between January 2008 and October 2010. Group I was composed of patients with chronically elevated IOP of at least 21 mmHg within a 1-year follow-up period. The rate of posttraumatic IOP elevation and associated structural and functional risk factors were evaluated.
Results: Of the 68 patients, 17 (25%) developed posttraumatic IOP elevation (Group 1). The mean age in group I was significantly older compared to group II (36.8±24.4 and 15.7±15.3 years, respectively [p=0.003]). Iris damage, postoperative inflammation, and use of long-term corticosteroids were significantly greater in group I (p<0.001, p<0.001, p=0.005 respectively). In group I, 13 of 17 patients (76.5%) had a wound size larger than 6 mm compared to only one patient (1/51, 2%) in group II, and the result was statistically significant (p<0.001). The size of wound larger than 6 mm also retained its statistical significance in multivariate analysis (p<0.001, odds ratio: 162.5).
Conclusion: This study shows a significant relationship between larger wound size (>6 mm) and elevation of IOP after trauma in zone I open globe injuries.
