Quantitative assessment of atypical birefringence images using scanning laser polarimetry with variable corneal compensation.
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...
متن کاملDetection of glaucoma with scanning laser polarimetry.
OBJECTIVE To determine which retinal nerve fiber layer (RNFL) measures obtained with scanning laser polarimetry are most useful in detecting early to moderate glaucomatous visual field loss. SUBJECTS AND METHODS One eye from 84 healthy individuals and 83 patients with early to moderate glaucomatous visual field loss (167 eyes) was assessed with a scanning laser polarimeter (Laser Diagnostic T...
متن کاملRetinal scanning laser polarimetry and methods to compensate for corneal birefringence.
Scanning laser polarimetry (SLP) was developed to provide objective assessment of the retinal nerve fiber layer (RNFL), a birefringent tissue, by measuring the total retardation in the reflected light. The birefringence of the anterior segment of the eye, mainly the cornea, is a confounding variable to the RNFL measurement. Anterior segment birefringence varies over a wide range among individua...
متن کاملScanning laser polarimetry with variable corneal compensation: identification and correction for corneal birefringence in eyes with macular disease.
PURPOSE In scanning laser polarimetry with variable corneal compensation (SLP-VCC), the macula is used as an intraocular polarimeter to calculate and neutralize corneal birefringence based on an intact Henle's layer. The purpose of this investigation was to validate this strategy in eyes with macular structural disease. METHODS A nerve fiber analyzer was modified to enable the measurement of ...
متن کاملThe effect of atypical birefringence patterns on glaucoma detection using scanning laser polarimetry with variable corneal compensation.
PURPOSE The purpose of this study was to investigate the effect of the presence of atypical birefringence patterns, as measured by the typical scan score (TSS), on the diagnostic accuracy of a scanning laser polarimeter (the GDx VCC; Carl Zeiss Meditec, Inc., Dublin, CA) assessed by receiver operating characteristic (ROC) curves for discriminating between glaucoma and healthy eyes. METHODS Tw...
