Abstract

Aim: To determine the visual outcomes in adult patients who sustained open globe injuries and to determine whether the visual prognosis following an eye injury in an African setting differs from the predicted outcomes according to the Ocular Trauma Score (OTS) study. A secondary aim was to establish the evisceration rate for these injuries and assess how this form of intervention affected outcomes in comparison to the OTS.

Methods: A prospective case series of all patients admitted with open globe injuries over a two-year (July 2009 to June 2011) period. Injuries were scored using the OTS and the surgical intervention was recorded. The best corrected visual acuity at three months was regarded as visual outcome.

Results: There were 249 open globe injuries, of which 169 patients (169 eyes) completed the 3-month follow-up. All patients underwent primary surgery, 175 (70.3%) repairs, 61 (24.5%) eviscerations and 13 (5.2%) other procedures. Globe eviscerations were mainly done on OTS Category 1 cases, but outcomes in this category were not found to be different from OTS outcomes. Outcomes were significantly worse in Category 2, but when the entire distribution was tested, the differences were not statistically significant. The overall association between OTS outcomes and the final visual outcomes in this study was found to be a strong (P<0.005).

Conclusion: Reliable information regarding the expected outcomes of eye injuries will influence management decisions and patient expectations. The OTS is a valuable tool, the use of which has been validated in many parts of the world-it may also be a valid predictor in an African setting.
