眼外伤常伴有眼部组织的多处损伤,其中前房积血、晶体混浊、晶体脱位、虹膜根部离断、房角后退、睫状体脱离等眼前节的损伤,临床表现多种多样。裂隙灯、房角镜和普通的眼B超等检查不易观察伴有屈光间质混浊的眼部结构及一些细小的变化。分辨率比较高的CT和MRI,有时也不能达到眼科临床检查的要求。UBM的出现,是眼科影像诊断技术发展史上一个新的里程碑,在眼外伤的检查中有着极其广泛的应用价值,对眼外伤尤其是眼前节结构损伤的法医临床学鉴定也具有重要的应用意义。 Ocular trauma is often accompanied by multiple injuries of the eye tissue, including anterior chamber hemorrhage, crystal opacity, dislocation of the crystal, the iris root rupture, angle retreat, ciliary body detachment and other anterior segment of the injury, a variety of clinical manifestations. Slit lamp, gonioscopy and ordinary eye B ultrasound examination is not easy to observe the ocular structure with refractive mesenchymal opacity and some small changes. High resolution CT and MRI, and sometimes can not meet the requirements of ophthalmic clinical examination. The emergence of UBM is a new milestone in the development of ophthalmic diagnostic imaging technology. It has an extremely wide range of applications in the inspection of ocular trauma. It is also of great significance for forensic clinical identification of ocular trauma, especially for anterior ocular segment structures.
