Purpose: To construct a comprehensive reference database (RDB) for a novel binocular automated perimeter.
Design: A four-site prospective randomized clinical trial.
Subjects And Controls: Three hundred fifty-six healthy subjects without ocular conditions that might affect visual function were categorized into 7 age groups.
Article Synopsis
- * It involved a retrospective cohort study and a case-control study, focusing on glaucoma patients from Veteran Affairs clinics and analyzing their VF results to categorize areas of pattern reversal as peripheral, paracentral, or mixed.
- * Results showed that eyes with mixed pattern reversal had significantly higher false-positive error rates (16.25%) compared to those with only paracentral (6.26%) or peripheral loss (8.15%), and individuals with paracentral loss were
Purpose: To analyze the relationship between rates of false positive (FP) responses and standard automated perimetry results.
Design: Prospective multicenter cross-sectional study.
Methods: One hundred twenty-six patients with manifest or suspect glaucoma were tested with Swedish Interactive Thresholding Algorithm (SITA) Standard, SITA Fast, and SITA Faster at each of 2 visits.
Purpose: To compare standard reliability metrics and gaze tracking (GT) metrics on the Humphrey field analyzer (HFA).
Design: Retrospective cross-sectional study.
Methods: The study was performed at the VA Medical Center, San Diego, and included 494 glaucoma and glaucoma suspect patients who had an HFA 24-2 SITA Fast visual field (VF) performed in both eyes.
Purpose: To describe a new time-saving threshold visual field-testing strategy-Swedish Interactive Thresholding Algorithm (SITA) Faster, which is intended to replace SITA Fast-and to report on a clinical evaluation of this new strategy.
Design: Description and validity analysis for modifications applied to SITA Fast.
Methods: Five centers tested 1 eye of each of 126 glaucoma and glaucoma suspect patients with SITA Faster, SITA Fast, and SITA Standard at each of 2 visits.
Purpose: To describe the process by which imaging devices undergo reference database development and regulatory clearance. The limitations and potential improvements of reference (normative) data sets for ophthalmic imaging devices will be discussed.
Method: A symposium was held in July 2013 in which a series of speakers discussed issues related to the development of reference databases for imaging devices.
Prediction of glaucomatous visual field loss by extrapolation of linear trends.
Arch Ophthalmol
December 2009
Objective: To investigate how well short-term progression rates can predict long-term visual field outcomes in patients with glaucoma.
Methods: We calculated visual field rates of progression using linear regression analysis of the Visual Field Index (VFI) for 100 consecutive patients with glaucoma having 10 or more Swedish Interactive Thresholding Algorithm standard field tests. Final VFI was predicted on the basis of linear extrapolation of the slope defined by the initial 5 field test results.
Purpose: To study optic nerve head (ONH) topography parameters measured by Stratus optical coherence tomography (OCT) in normal subjects and to analyze ONH data for differences in relation to disc size, ethnicity, and age.
Methods: Three hundred sixty-seven normal subjects underwent Stratus optical coherence tomography ONH measurement using the fast optic disc scan protocol software package 3.0.
Purpose: To determine the effects of age, optic disc area, ethnicity, eye, gender, and axial length on the retinal nerve fiber layer (RNFL) in the normal human eye as measured by Stratus OCT (optical coherence tomography).
Design: Cross-sectional observational study.
Participants: Three hundred twenty-eight normal subjects 18 to 85 years old.
