Visual outcome and ocular survival in open-globe injuries

AIM: To detect the risk factors that predicts final visual acuity, retinal detachment, and ocular survival after penetrating trauma. METHODS: In a prospective case series study, 116 eyes with open-globe injuries were evaluated between 2001 and 2004. All data were filled in the questionnaire chart. Sex, age, involved eye, best-corrected visual acuity (BCVA), afferent pupillary defect (APD), location and wound length, cataract, iris prolapse, vitreous prolapse, retinal detachment (RD), intraocular foreign body (IOFB), vitrectomy procedure, and type of injury were evaluated as predisposing factors by logistic regression models for final visual acuity, RD, and ocular survival. RESULTS: Low BCVA, RD, and vitrectomy procedure were detected significant in the final visual acuity of 20/200 or less. APD and vitrectomy procedure were statistically significant in the final RD. BCVA 20/250 or less, wound length >10mm, scleral and corneoscleral lacerations, vitreous prolapse, vitreous hemorrhage, RD, and sharp injury were correlated with decreased globe survival. CONCLUSION: Low BCVA, APD, and vitrectomy procedure were effective in the visual outcome. RD and vitrectomy procedure were detected significant in the anatomic result. Establishment of predictors of visual outcome and ocular survival may assist clinicians in salvageable eyes for surgical repair.
