Abstract

The purpose of this investigation was to evaluate the role of ultrasound biomicroscopy (UBM) as a method for assessing the zonules after blunt trauma. Twenty-five patients were participated in this study, who had underwent ocular blunt trauma. UBM examinations were performed using the Humphrey Instruments Ultrasound Biomicroscope equipped with a 50-mHz transducer. A plastic eyecup filled with 2% methylcellulose solution was used in each case. Data were obtained at each 45 degree position. We can find zonular defect in 13 of 21 patients (52.0%). Zolulolysis less than one forth were found in 4 (30.8%) and more than a half in 9 (69.2%). UBM is an effective method for identifying zonular damage in patients with ocular blunt trauma. Also, it is helpful to the surgeon to reduce the chance of intraoperative complications.
