Analytical model of scanning laser polarimetry for retinal nerve fiber layer assessment.
PURPOSE To develop a quantitative understanding of scanning laser polarimetry (SLP) for retinal nerve fiber layer (RNFL) assessment in glaucoma diagnosis and management. METHODS The Mueller calculus was used to model the polarization optics of SLP. A birefringent retinal structure (RNFL or macula) was represented as a circularly symmetric linear retarder with a radial slow axis. The birefring...
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 کاملScanning Laser Topography and Scanning Laser Polarimetry: Comparing Both Imaging Methods at Same Distances from the Optic Nerve Head
PURPOSE To compare the performance of scanning laser topography (SLT) and scanning laser polarimetry (SLP) on the rim of the optic nerve head and its surrounding area and thereby to evaluate whether these imaging technologies are influenced by other factors beyond the thickness of the retinal nerve fiber layer (RNFL). MATERIALS AND METHODOLOGY A total of 154 eyes from 5 different groups were ...
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 کاملParafoveal Scanning Laser Polarimetry for Early Glaucoma Detection
Purpose: To investigate the glaucoma change detection in the parafoveal area using scanning laser polarimeter (SLP). Methods: Fourteen eyes with early glaucoma which have a point with 6 dB or more decrease in pattern deviation with the Humphrey Field Analyzer (HFA) 30–2 program within central 10 degrees visual field, and 14 normal control eyes were enrolled in this study. The average of the mea...
