To evaluate the ultrasound biomicroscopic appearance of anterior segment foreign bodies under clinical and experimental conditions.
Ultrasound biomicroscopy was performed on 4 eyes of 4 patients referred for evaluation of anterior segment trauma and known or suspected intraocular foreign body. Imaging of wood, aluminum, concrete, and glass foreign bodies was performed in the anterior chamber of a human cadaver eye.
Ultrasound biomicroscopy verified the location of a foreign body in two patients and identified occult foreign bodies in two others. Under clinical and experimental conditions, intraocular aluminum and glass produced comet tail artifacts. Under experimental conditions intraocular wood and concrete produced shadowing artifacts.
Ultrasound biomicroscopy provides useful information in the evaluation of known and occult anterior segment foreign bodies. Ultrasound patterns of shadowing and comet tail may help differentiate foreign body materials.
评估临床和实验条件下眼前段异物的超声生物显微镜表现。
对4例因眼前段外伤并已知或怀疑有眼内异物而转诊的患者的4只眼睛进行超声生物显微镜检查。在人尸体眼的前房内对木头、铝、混凝土和玻璃异物进行成像。
超声生物显微镜检查证实了2例患者眼内异物的位置，并在另外2例患者中发现了隐匿性异物。在临床和实验条件下，眼内铝和玻璃产生彗尾伪像。在实验条件下，眼内木头和混凝土产生阴影伪像。
超声生物显微镜检查在评估已知和隐匿性眼前段异物方面提供了有用信息。阴影和彗尾的超声模式可能有助于区分异物材料。
