Size Matters for Interplicata Diameter: A Case-Control Study of Plateau Iris.

Purpose: Ultrasound biomicroscopy (UBM) has been used to characterize anterior segment dimensions in plateau iris configuration (PIC), but transverse measurements between the recesses of the ciliary sulcus (sulcus-to-sulcus diameter [STSD]) and the ciliary body processes (interplicata diameter [IPD]) have not been reported. We measured STSD and IPD and compared these among eyes with PIC, primary angle closure (PAC), and control eyes with open angles.

Design: Retrospective, cross-sectional clinical study.

Mechanisms for in-the-bag uveitis-glaucoma-hyphema syndrome.

We propose 2 mechanisms of uveitis-glaucoma-hyphema (UGH) syndrome in 2 patients with intracapsular or in-the-bag single-piece acrylic intraocular lenses (IOLs). In the first case, pseudophacodonesis secondary to zonular laxity from pseudoexfoliation syndrome caused chafing of the posterior iris by the square-edged haptic. In the second case, focal capsular fibrosis around the square-edged haptics combined with anteriorly rotated ciliary processes in plateau iris configuration caused points of chafing.
