Relative lens vault in subjects with angle closure
BACKGROUND The purpose of this study was to investigate the association of a novel biometric parameter, relative lens vault (LV), with primary angle-closure (PAC) and primary angle-closure glaucoma (PACG). METHODS We evaluated 101 subjects with PAC (G) and 101 normal subjects that were age- and gender-matched. Based on anterior-segment optical coherence tomography scans, and using customized ...
متن کاملLens extraction in primary angle closure.
T he crystalline lens has a pivotal role in primary angle closure (PAC), both in the pathogenesis of pupil block and by exacerbating the effect of non-pupil block mechanisms such as peripheral iris crowding. Eyes with angle closure tend to have shallow anterior chambers and thick, anteriorly positioned lenses when compared with normal eyes. Removing the lens creates more space in the anterior c...
متن کاملThe role of clear lens extraction in angle closure glaucoma
Clear lens extraction can be considered a therapeutic option in angle closure glaucoma (ACG). Even if it does not represent the first choice of treatment, it can be taken into consideration when the topical treatment does not control the intraocular pressure (IOP) and iridotomy does not have a positive effect on the angle closure, especially in appositional angle closure when biometry or ultrab...
متن کاملRole of Lens Extraction in Primary Angle Closure Disease
An eye with angle closure glaucoma is anatomically characterized by a short axial length, a shallow anterior chamber, a thickened lens that is situated relatively anteriorly and a small corneal diameter. These conditions may lead to the development of relative pupillary block. Pupillary block is classically managed with a peripheral iridectomy which provides a route for the aqueous to drain. Bu...
متن کاملPrimary 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...
