The Difference of Lens Thickness in Acute and Chronic Primary Angle Closure Glaucoma

Primary acute angle-closure glaucoma damage to cornea and lens.

The following corneal conditions will be considered: (1) pressure oedema; (2) oedema following endothelial damage; (3) persistent folds in Descemet's membrane; (4) vascularization; (5) lipoid infiltration; (6) band-shape degeneration. Oedema of the cornea caused by a sudden elevation of intra-ocular pressure is a diagnostic feature of acute angle-closure glaucoma. If the intra-ocular pressure r...

Gonioscopic Features in Patients with Acute and Chronic Angle-Closure Glaucoma

Background: A number of ocular biometric parameters, iris hiotologic and anatomic characters have been suggested as inciting factors for converting patients with narrow angle to angle-closure glaucoma. This study was conducted to determine if there was any goniscopic difference between patients with acute angle-closure glaucoma (AACG) and chronic angle-closure glaucoma (CACG). Methods: ...

Increased iris thickness and association with primary angle closure glaucoma.

AIMS To investigate the relationship between quantitative iris parameters and angle closure disease. methods: Participants with angle closure were recruited prospectively from glaucoma clinics. Anterior segment optical coherence tomography (AS-OCT) was performed under standardised dark conditions. Customised software was used on horizontal AS-OCT scans to measure iris thickness at 750 um...

Primary Angle Closure Glaucoma

A prospective comparison of chronic primary angle-closure glaucoma versus primary open-angle glaucoma in Singapore.

INTRODUCTION To describe the optic disc, visual field and ocular characteristics of a consecutive cohort of Asian patients with chronic primary angle-closure glaucoma (CPACG), and compare them with those having primary open-angle glaucoma (POAG). METHODS In a prospective comparative case series of new patients with POAG or CPACG in Singapore, all patients underwent visual acuity assessment, s...
