Ultrasound biomicroscopy findings in fireworks-related blunt eye injuries

Abstract

To present ultrasound biomicroscopic (UBM) findings and their clinical correlations in people with optically hazy media after injury at the Persian Wednesday Eve fireworks festival. Ultrasound biomicroscopy was performed on a series of 32 eyes with severe closed-globe injuries by P40 ultrasound biomicroscope. The median age of the participants was 19 years, and 81.3% were male. All but one had gross hyphema. Seventy-five percent had an extension of the injury (at least) to Birmingham Eye Trauma Terminology zone II. Ultrasound biomicroscopy detected 3 more iridodialyses and 10 more cyclodialyses in addition to the respective 5 and 3 that were diagnosed clinically. Ten cases of angle recession were observed, and 5 were suggestive of subluxation of the crystalline lens. Two cases were suspected for anterior segment intraocular foreign body on clinical examination, but UBM and computed tomography scanning together ruled out such a diagnosis. Our study showed the value of UBM in the assessment of severely contused eyes and hyphema. It made possible evaluation for dialyses and recessions at presentation. Ultrasound biomicroscopy illustrated diverse subclinical disruptions in clinically invisible anterior segment structures.
