OBJECTIVES Subjective visual deficits are common after demyelinating optic neuritis despite the frequent return of normal visual acuity. Visual and electrodiagnostic tests have demonstrated evidence of these persisting functional abnormalities, which are thought to be secondary to demyelination and variable axonal loss in the optic nerve. Scanning laser polarimetry (SLP) is a new image analysis...
PURPOSE To evaluate the birefringence properties of eyes with age-related macular degeneration (AMD). To compare the information from two techniques--scanning laser polarimetry (GDx) and polarization-sensitive spectral-domain optical coherence tomography (OCT)--and investigate how they complement each other. METHODS The authors prospectively examined the eyes of two healthy subjects and 13 pa...
Aims: To evaluate different algorithms used to analyse retinal nerve fibre layer thickness (RNFL) data obtained by scanning laser polarimetry, in order to compare their relative abilities to discriminate between patients with glaucomatous localised nerve fibre layer defects and normal subjects. Methods: 48 eyes of 48 glaucomatous patients with localised RNFL defects and 53 eyes of 53 healthy su...
Advanced ocular imaging technologies facilitate objective and reproducible quantification of change in glaucoma but at the same time, impose new challenges on scientists and clinicians for separating true structural change from imaging noise. This review examines time-domain and spectral-domain optical coherence tomography, confocal scanning laser ophthalmoscopy and scanning laser polarimetry t...
Numerous articles describe findings from patients with known and suspected glaucoma using confocal scanning laser ophthalmoscopy (CSLO), scanning laser polarimetry (SLP), and optical coherence tomography (OCT). These studies report that abnormalities may be detected on these examinations before functional changes are noted.(1) The literature, specialty society guidelines, and clinical input ind...
PURPOSE Aim of the present study was to evaluate whether there is a correlation between retinal blood vessel density (RVD) and the peripapillary retinal nerve fiber layer (RNFL) thickness profile. METHODS RNFL thickness of 106 healthy subjects was measured using scanning laser polarimetry, GDx variable corneal compensation (VCC), and GDx enhanced corneal compensation (ECC). A proprietary soft...
This report is of a patient with ischemic central retinal vein occlusion who underwent panretinal photocoagulation. Serial measurements of the retinal nerve fiber layer were performed using scanning laser polarimetry, which showed increased thickness of the peripapillary region as early as 2 weeks after the panretinal photocoagulation.
