  • Title: [A preliminary ultrasound biomicroscopic study of anterior segment structures in normal human eyes].
    Author: Yang W, Liu L, Li X.
    Journal: Zhonghua Yan Ke Za Zhi; 1997 Mar; 33(2):85-7. PubMed ID: 10437006.
    Abstract:
    OBJECTIVE: We investigated anterior segment structures in normal human eyes by ultrasound biomicroscopy (UBM). METHOD: UBM high frequency transducer (50-100mHz) was used to measure the anterior segment of normal human eyes. RESULT: Cornea, sclera, iris, lens, ciliary body, anterior chamber, posterior chamber and extraocular muscles can be visualized by UBM. CONCLUSION: UBM is a new noninvasive method for imaging the anterior segment structures under living condition, and supplementary to the present existing imaging methods that have shortcomings in dynamic observation of the anterior ocular structures under such condition. As the frequency of the transducer is rather high, the imaging depth is limited to 4-5 mm, thus only the anterior ocular structures can be viewed.
