PURPOSE To determine the reproducibility of Stratus OCT peripapillary retinal nerve fiber layer (RNFL) measurements in glaucomatous eyes. DESIGN Experimental study. PARTICIPANTS Fifty-one stable glaucoma patients with a range of severity. METHODS Peripapillary RNFL thickness was measured using the Standard and Fast scan protocols of Stratus optical(More)
PURPOSE To present and evaluate a new method of estimating rates of retinal ganglion cell (RGC) loss in glaucoma by combining structural and functional measurements. DESIGN Observational cohort study. METHODS The study included 213 eyes of 213 glaucoma patients followed up for an average of 4.5 ± 0.8 years with standard automated perimetry visual fields(More)
PURPOSE To determine the reproducibility of the pattern electroretinogram with the new Pattern Electroretinogram for Glaucoma (PERGLA) recording paradigm in glaucoma patients with a range of severity. DESIGN Experimental study. PARTICIPANTS Fifty-three glaucoma patients were recruited for the study (mean age +/- standard deviation [SD], 69+/-11 years).(More)
A 1-yr retrospective study was undertaken to verify whether the prevalence of cellulitis in broiler chicken flocks was associated 1) with sex and average body weight controlling for the time of year and 2) with some other condemnation causes such as air-sacculitis, ascites, cyanosis, emaciation, valgus varus deformity, peritonitis, and total condemnation(More)
OBJECTIVE To evaluate a new method of quantifying and visualizing discordance between structural and functional measurements in glaucomatous eyes by predicting the visual field (VF) from retinal nerve fiber layer thickness (RNFLT) using a bayesian radial basis function. METHODS Five GDx VCC RNFLT scans and 5 Humphrey 24-2 Swedish Interactive Thresholding(More)
PURPOSE We evaluated Progression of Patterns (POP) for its ability to identify progression of glaucomatous visual field (VF) defects. METHODS POP uses variational Bayesian independent component mixture model (VIM), a machine learning classifier (MLC) developed previously. VIM separated Swedish Interactive Thresholding Algorithm (SITA) VFs from a set of(More)
PURPOSE To study the performance of the Matrix perimeter compared with the Humphrey Field Analyzer II (HFA) with the Swedish Interactive Thresholding Algorithm over the range of contrast sensitivities each machine could estimate. METHODS Fifty stable glaucoma subjects at various stages of disease and three normal subjects had visual fields testing done on(More)
