Abstract

PURPOSE
To evaluate the clinical significance of angle-opening distance 500 (AOD500) using ultrasound biomicroscopy (UBM) in the early stage of traumatic hyphema. METHODS: The participants of this study were 46 hospitalized traumatic hyphema patients. We measured the quantity of initial blood clotting using a slit-lamp and the range of angle recession, AOD500 using UBM and then reviewed the relationship between the two. RESULTS: The difference of AOD500 in the traumatic and the non-traumatic eye measured by UBM at admission increased significantly in the wider recessed angle group (p=0.008), but did not increase at a statistically significantly level in the larger initial blood clot grade group (> or =Grade 2). CONCLUSIONS: These results suggest that the measurement of the angle-opening distance of both eyes using UBM will aid in evaluating the range of angle recession in patients in the early stage of traumatic hyphema.
