Background: This study was undertaken to determine whether a difference exists in treatment outcome between patients treated with tranexamic acid (TEA) plus topical steroids and those treated with topical steroids alone.
Methods: A retrospective cohort study was conducted to compare treatment results for children with traumatic hyphema treated with TEA and topical steroids versus topical steroids alone. Patients were identified from a chart review of the Children's Hospital of Eastern Ontario eye clinic and the Queen's Department of Ophthalmology emergency eye clinic for charts coded "traumatic hyphema." The primary outcomes measured included visual acuity, rebleed rate, intraocular pressure, and time to hyphema resolution. Covariates were hyphema grade, the need for medications to lower intraocular pressure, and the presence of associated ocular traumatic complications. Analysis was performed with both bivariate analysis and multivariate models.
Results: Two hundred and fifteen patients with traumatic hyphema were included in our study. One hundred and thirty-seven patients (63.1%) received TEA plus topical steroids, and the remaining 78 patients received topical steroids alone. There was no significant difference in rebleed rate between the TEA plus topical steroid group (1.6%) and the steroid-alone group (2.6%, p = 0.60).
Interpretation: Patients with traumatic hyphema treated with TEA plus topical steroids did not have a significantly lower incidence of rebleed than those treated with topical steroids alone.
