purpose: to quantify the intraobserver reproducibility of retinal nerve fiber layer (rnfl) measurements using scanning laser polarimetry with variable corneal compensation in glaucoma suspect patients. methods: twenty-six eyes of 26 glaucoma suspect patients were included. complete ophthalmologic examination and standard automated perimetry were performed for all of them. rnfl measurements were...

PURPOSE To evaluate the structure/function relationship between visual field sensitivity and retinal nerve fiber layer (RNFL) thickness measured by StratusOCT (Carl Zeiss Meditec, Inc., Dublin, CA) and GDx VCC (Laser Diagnostic Technologies, Inc., San Diego, CA). METHODS Eighty-nine subjects (27 who had healthy eyes, 21 who were glaucoma suspect, 41 who had glaucoma) were enrolled in this cro...

PURPOSE To compare the structure-function relationship between peripapillary retinal nerve fiber layer (RNFL) retardation, measured with scanning laser polarimetry (SLP) with both enhanced and variable corneal compensation (ECC [enhanced corneal compensation] and VCC [variable corneal compensation], respectively; features of the GDx Nerve Fiber Analyzer; Carl Zeiss Meditec, Inc., Dublin, CA), a...

PURPOSE To investigate the impact of diabetic retinopathy on quantitative retinal nerve fiber layer (RNFL) assessment and diagnostic power for glaucoma by scanning laser polarimetry (GDx-VCC) and optical coherence tomography (StratusOCT). METHODS The individual RNFL parameters of GDx and OCT were obtained for 170 eyes (one eye from each of 170 subjects [45 healthy, 47 glaucoma, 40 diabetes, a...

PURPOSE To evaluate quantitatively the intraobserver reproducibility of measurements of the retinal nerve fiber layer (RNFL) in healthy subjects and an ocular hypertensive population using two nerve fiber analyzers. METHODS Sixty eyes of normal (n=30) and ocular hypertensive subjects (n=30) were consecutively recruited for this study and underwent a complete ophthalmologic examination and ach...

PURPOSE To investigate the relationship between optical coherence tomography (OCT) and scanning laser polarimetry (SLP) in measuring peripapillary retinal nerve fiber layer (RNFL) thickness in glaucomatous eyes. METHODS Fifty glaucomatous eyes were evaluated in this study. Evaluations were analyzed two ways. First, parameters of the Stratus OCT (average thickness, superior/inferior average) a...

BACKGROUND We compared the parameters of retinal nerve fibre layer in patients with advanced glaucoma with the use of different OCT (Optical Coherence Tomograph) devices in relation to analogical measurements performed with GDx VCC (Nerve Fiber Analyzer with Variable Corneal Compensation) scanning laser polarimetry. MATERIAL/METHODS Study subjects had advanced primary open-angle glaucoma, pre...

purpose: to examine the relationship between retinal nerve fiber layer (rnfl) measurements obtained using scanning laser polarimetry with variable corneal compensation (vcc) and central corneal thickness (cct) measurements using pentacam in myopic patients methods: the study included 45 eyes from 45 myopic patients with intraocular pressure (iop) measurements≤21 mmhg. all participants had norma...

PURPOSE To compare optic disk and retinal nerve fiber layer (RNFL) imaging methods to discriminate eyes with early glaucoma from normal eyes. DESIGN Retrospective, cross-sectional study. METHODS In a tertiary care academic glaucoma center, 92 eyes of 92 subjects (46 with early perimetric open-angle glaucoma and 46 controls) were studied. Diagnostic performance of optical coherence tomograph...

PURPOSE To define the clinical characteristics of atypical birefringence images and to describe a quantitative method for their identification. DESIGN Prospective, comparative, clinical observational study. METHODS Normal and glaucomatous eyes underwent complete examination, standard automated perimetry, scanning laser polarimetry with variable corneal compensation (GDx-VCC), and optical co...
