Angle-closure caused by an anterior segment membrane

Anterior segment imaging in angle-closure disease

Introduction Angle-closure disease (both primary and secondary) is a spectrum of disorders characterized by iridotrabecular contact obstructing aqueous outflow. Anterior segment imaging plays an important role in understanding the pathophysiology of angle closure, diagnosis, and monitoring the treatment, especially in challenging cases. Indirect gonioscopy, the gold standard for visualizing the...

Qualitative evaluation of anterior segment in angle closure disease using anterior segment optical coherence tomography

PURPOSE To evaluate different mechanisms of primary angle closure (PAC) and to quantify anterior chamber (AC) parameters in different subtypes of angle closure disease using anterior segment optical coherence tomography (AS-OCT). METHODS In this prospective study, 115 eyes of 115 patients with angle closure disease were included and categorized into three groups: 1) fellow eyes of acute angle...

Major determinants of acute primary angle closure demonstrated by anterior segment optical coherence tomography.

Comparison of Anterior Segment-Optical Coherence Tomography Parameters in Phacomorphic Angle Closure and Acute Angle Closure Eyes.

PURPOSE The purpose of this study is to compare anterior segment-optical coherence tomography (AS-OCT) parameters in phacomorphic angle closure and acute primary angle closure (APAC) eyes. METHODS In this cross-sectional case series, a total of 134 patients with phacomorphic angle closure (28 eyes) or APAC (54 eyes), as well as normal control subjects (52 eyes), were enrolled. Patients underw...

Anterior Segment Morphology in Primary Angle Closure Glaucoma using Ultrasound Biomicroscopy

Aim To evaluate the configuration of the anterior chamber angle quantitatively and study the morphological changes in the eye with ultrasound biomicroscopy (UBM) in primary angle closure glaucoma (PACG) patients after laser peripheral iridotomy (LPI). Materials and methods A total of 185 eyes of 185 PACG patients post-LPI and 126 eyes of 126 normal subjects were included in this prospective s...
