Hussein MA, et al. - Researchers examined the influence of perioperative dexamethasone, presumed to reduce edema, on the success rate of nasolacrimal duct obstruction (NLDO) treatment by balloon dacryoplasty. They retrospectively reviewed the medical records of patients treated for NLDO using balloon dacryoplasty. Patients either received intravenous dexamethasone perioperatively at a dose of 0.50 mg/kg or no dexamethasone. Perioperative dexamethasone use was noted to be associated with a reduced rate of failure in children in this study cohort.
