Prognostic Factors in Open Globe Injuries

Abstract

Purpose:  To detect the factors affecting the final visual acuity in open globe injuries.

Material And Methods: Fifty eight eyes of 58 patients who were treated for open globe injuries were analysed prospectively. Factors which are deemed to have effect on visual prognosis were examined statistically.

Results: Forty five patients (%77.6) were male, with a mean age of 29.6 ±19.4. Final visual acuity was 0.1 and lower in 28 (%48.3) cases. The prognostic factors predicting the final visual acuity were initial visual acuity, wound size, mechanism of the injury, presence of relative afferent pupillary defect (RAPD), zone of the injury, anterior chamber finding, lens injury, posterior segment finding, uveal injury  and Ocular Trauma Score . According to multiple retrospective logistic regression analysis, those factors having the highest effect  on final visual acuity were found to be presence of an  RAPD, female gender, old age and large laceration respectively.

Conclusion: Initial examination findings are helpful for predicting the visual outcome in open globe injuries. Therefore, standardization in classification of the initial examination findings is compulsory.
