Corneal hysteresis and visual field asymmetry in open angle glaucoma.
PURPOSE To investigate the association between corneal biomechanical parameters and asymmetric primary open angle glaucoma (POAG) using the Ocular Response Analyzer (ORA). METHODS In a prospective cross-sectional study, ORA parameters were measured in 117 POAG patients with asymmetric visual fields (VF). The asymmetry in VF was defined as a five point difference between the eyes using the Adv...
متن کاملErratum. Lack of Association Between Corneal Hysteresis and Corneal Resistance Factor With Glaucoma Severity in Primary Angle Closure Glaucoma.
PURPOSE We investigated the association between corneal hysteresis (CH) and corneal resistance factor (CRF) with glaucoma severity in primary angle closure glaucoma (PACG). METHODS We recruited 204 subjects with PACG. Each subject underwent CH and CRF measurements using the Ocular Response Analyzer (ORA), optic nerve head topography measurement using scanning laser ophthalmoscopy, and visual ...
متن کاملPrimary open-angle glaucoma
Primary open-angle glaucoma (POAG) is an idiopathic disorder in which the resistance to outflow through the trabecular meshwork gradually increases and the intraocular pressure (IOP) rises, causing irreversible damage to the optic nerve POAG is the second most common cause of vision loss in the U.S. Usually asymptomatic until advanced visual field loss has occurred; less than 50% of those...
متن کاملScreening of CYP1B1 Arg368His as predominant mutation in North Indian primary open angle glaucoma and juvenile onset glaucoma patients
In India, mutations in Cytochrome P450 (CYP1B1) are a predominant cause of not only primary congenital glaucoma (PCG) but also involved in primary open angle glaucoma (POAG) and juvenile onset glaucoma (JOAG). After ethical clearance, 100 POAG patients, 30 primary angle closure glaucoma (PACG) patients and 130 ethnically matched controls were recruited in this study. Genomic DNA was is...
متن کاملNew Technologies in Diagnosis of Primary Open-angle Glaucoma
The purpose of the study is to determine the most important diagnostic criteria for distinguishing preperimetric glaucoma from perimetric glaucoma on the basis of a comprehensive assessment of structural changes and indicators of ocular blood flow. 90 eyes, including 30 eyes with preperimetric glaucoma, 30 eyes with perimetric glaucoma, and 30 normal eyes were analyzed in the present study. The...
