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

Figure 1

Clinical characteristics of a patient with lens subluxation with AAC attack. (a) Affected eye (right eye): slit-lamp biomicroscopy demonstrated that the anterior chamber depth (ACD) was shallow in central region, and it was shallower in periphery (arrow). Imaging by ultrasound biomicroscopy (UBM) showed a 1.25 mm central ACD, whereas the peripheral nasal ACD was shallower (arrows). The lens vault (LV) was 1.48 mm. (b) Fellow eye (left eye): the central and peripheral ACD were wider than in the affected eye. The central ACD was 2.08 mm and the lens vault (LV) was 0.95 mm. The LV is defined as the perpendicular distance between the anterior pole of crystalline lens and horizontal line joining two scleral spurs. AAC, acute angle closure; Corn, cornea; S, sclera; I, iris; PC, posterior chamber.
