Comparisons of Ocular Anatomic Differences of Lens-Subluxated Eye with or without Acute Angle Closure: A Retrospective Study

Figure 2

Ultrasound biomicroscopic examination of the affected eye in a patient with subluxated lens-induced AAC. (a) and (b) illustrated the structures of zonular bundles (white arrow) and slit-like opened anterior chamber angles (blank arrows) at 12 : 00 and 3 : 00, respectively. (c) An irregular hyperreflectivity (white arrow) and a completely occluded angle (blank arrows) were noted at 6 : 00, but the appearance of zonular fibers was defective. (d) The zonules were also absent at 9 : 00 and the angle was closed appositionally (blank arrows). AAC, acute angle closure; Corn, cornea; S, sclera; AC, anterior chamber; I, iris; PC, posterior chamber; L, lens; LC, lens capsule; CB, ciliary body.
