Role of 25 MHz Ultrasound Biomicroscopy in the Detection of Subluxated Lenses

Figure 2

Subluxated lenses with age-related cataract images obtained in the same patient with 25 and 50 MHz UBM. (a) A 25 MHz UBM axial section image shows that the anterior chamber geometry is distorted, the distance between the ciliary process and lens equator is increased on the subluxated side, and the side of the lens equator with increased distance is more curved than the other side; the opacity of the lens, ciliary process, lens zonule, and lens equator are shown clearly (arrows); (b) a 50 MHz UBM axial section image shows only that the anterior chamber geometry is distorted; the distance of the subluxated side and other lesion features of the lens are not shown clearly; (c, d) the 50 MHz UBM longitudinal section images show the difference in the distance between the ciliary process and lens equator. The distance between the ciliary process and lens equator in (d) is longer than that in (c).
