机械性眼球外伤后，常伴有屈光间质的混浊，超声检查可提供重要诊断依据。本文总结报告了72例（77只眼）眼球机械外伤的病例。以75MHz高频探头检查，对外伤后前房积血、晶体损伤、球内异物、玻璃体积血及膜状物形成、视网膜脱离的超声特征进行了描述，探讨这些表现随外伤时间的长短不同、程度不同所具有的敏感性和特异性。结论：超声检查是机械性眼球外伤的敏感可靠的检查手段。 Mechanical eye trauma, often accompanied by refractive opacity opacity, ultrasound can provide important diagnostic basis. This article summarizes the report of 72 cases (77 eyes) cases of mechanical eye injury cases. To 75MHz high-frequency probe examination, post-traumatic hyphema, crystal damage, intracranial foreign body, vitreous hemorrhage and membranous formation, retinal detachment of the ultrasound features were described to explore the performance of these traumatic time with different length, Degree of sensitivity and specificity of different. Conclusion: Ultrasonography is a sensitive and reliable means of detecting mechanical eye injuries.
