The effect of injury type and location on the prognosis of the patients with open globe injuries

Abstract

Objective: Investigation of the effect of the globe injury site and the globe injury type on the postoperative results in the patients with a relatively softer open globe injury (OGI) was aimed. Methods: Medical records of the patients with OGI due to blunt or penetrating trauma were analyzed retrospectively. The patient cohort was divided into laceration and rupture groups. The location of injury was evaluated in zones (I-II-III). Presence and type of the complication (cataract, retinal detachment, etc.) were evaluated. Final best-corrected visual acuity (BCVA) was evaluated as the primary outcome measure. Results: Seventy eyes of 70 patients with OGI were included in the study. While 58 eyes (82.9%) had lacerations, 12 eyes (17.1%) had ruptures. Among the 52 patients with lacerations for whom there was an available BCVA data, 13 (25%) patients showed no change, 32 (61.5%) showed an increase, and 7 (13.5%) showed a decrease in BCVA. Among the 11 patients with ruptures, 2 (18.2%) patients showed no change and 9 (81.8%) showed an increase in BCVA. A complication was observed in 23 (44.2%) patients with laceration and 4 (33.3%) patients with rupture (p: 0.474). No difference was detected in terms of the complication rate between the patients having a different zone of injury. However, final BCVA was lower in those with Zone III injury in comparison to those with Zone II injury (p: 0.028). Conclusion: Although the injury type was thought to have an effect on the final BCVA of the patients with OGI, no difference was detected between the patients with laceration and rupture. Zone III injuries resulted in lower preoperative BCVA values. However, despite a significant difference between Zone II and III injuries, no significant difference was observed in terms of the final BCVA between the patients with Zone I and those with Zone III injuries.
