Comparative biometric study between plateau iris configuration and primary open angle glaucoma with narrow angle

Prevalence and characteristics of plateau iris configuration among American Caucasian, American Chinese and mainland Chinese subjects

“…We therefore hypothesise that the longer AL can potentially provide longer distance between the iris and trabecular meshwork, even in the event of anterior angulations of the ciliary processes, which in turn helps to prevent angle closure formation. This is consistent with previous reports, where among patients with PIC, those with narrow angles had shorter AL than those with POAG 22. On the other hand, we did not find any difference in AL between patients who had PIC and those who did not among mainland Chinese subjects.…”
