Humphrey Matrix Perimetry for Open-Angle Glaucoma Screening in A High-Risk Population
The aim of this study was to evaluate the role of Humphrey Matrix perimetry to better guide appropriate referral of at-risk individuals for glaucoma assessment. Fifty-two consecutive patients referred to a specialist glaucoma ophthalmology practice for an opinion about a new diagnosis of glaucoma were enrolled. Prior to assessment for presence of open-angle glaucoma, patients performed Humphrey...
متن کاملA Comparison of Perimetric Results from a Tablet Perimeter and Humphrey Field Analyzer in Glaucoma Patients
PURPOSE To determine the correlation between the perimetric outcomes from perimetry software Melbourne Rapid Fields (MRF) run on an Apple iPad tablet and those from the Humphrey Field Analyzer (HFA). METHODS The MRF software was designed with features including variable fixation and fast thresholding using Bayes logic. Here, we report a cross-sectional study on 90 eyes from 90 participants: 1...
متن کاملStructural and Functional Relationships in Glaucoma Using Standard Automated Perimetry and the Humphrey Matrix
PURPOSE To evaluate and compare correlations between structural and functional loss in glaucoma as assessed by optical coherence tomography (OCT), scanning laser polarimetry (GDx VCC, as this was the model used in this study), standard automated perimetry (SAP), and the Humphrey Matrix (Matrix). METHODS Ninety glaucomatous eyes identified with SAP and 112 eyes diagnosed using Matrix were inde...
متن کاملIdentifying "preperimetric" glaucoma in standard automated perimetry visual fields.
PURPOSE To compare the visual fields (VFs) of preperimetric open angle glaucoma (OAG) patients (preperimetric glaucoma VFs, PPGVFs) with the VFs of healthy eyes, and to discriminate these two groups by using the Random Forests machine-learning method. METHODS All VFs before a first diagnosis of manifest glaucoma (Anderson-Patella's criteria) were classified as PPGVFs. Series of VFs were obtai...
متن کاملVisual field progression with frequency-doubling matrix perimetry and standard automated perimetry in patients with glaucoma and in healthy controls.
IMPORTANCE A new analysis method called permutation of pointwise linear regression measures the significance of deterioration over time at each visual field location, combines the significance values into an overall statistic, and then determines the likelihood of change in the visual field. Because the outcome is a single P value, individualized to that specific visual field and independent of...
