متن کاملVisual field testing for glaucoma – a practical guide
Examining visual fields is an integral part of a full ophthalmic evaluation. Several methods for assessing visual field loss are available, and the choice of which to use depends on the patient’s age, health, visual acuity, ability to concentrate, and socio-economic status. Available techniques can test the full field (including confrontation, tangent screen, Goldmann perimetry and automated pe...
متن کاملComparison of contrast sensitivity, visual acuity, and Humphrey visual field testing in patients with glaucoma.
BACKGROUND Despite their normal or near-normal Snellen visual acuity, patients with glaucoma often complain of "poor" vision. OBJECTIVE To investigate the relationship between large-letter contrast sensitivity, high-contrast visual acuity, and visual field defects in patients with glaucoma who have 20/40 or better visual acuity. DESIGN Prospective, cross-sectional case series. PATIENTS AN...
متن کاملEvaluation of Visual Field Progression in Glaucoma
Detection of visual field progression is of critical importance in the management of patients with glaucoma; however, there is no agreed upon set of criteria for the definition of progression. The most commonly utilized method of progression detection in clinical practice may be subjective assessment of serial visual fields. Event-based and trend-based approaches to the analysis of serial visua...
متن کاملPrediction of visual field progression in glaucoma.
PURPOSE To determine the probability of future glaucomatous visual field (VF) progression with clinical and perimetric data. METHODS One hundred sixty-one eyes of patients (161) enrolled in the Advanced Glaucoma Intervention Study (AGIS) with >or=8 years of follow-up and a baseline VF score <or=16 were selected. VF progression at 8 years was determined with point-wise linear regression (PLR) ...
