OBJECTIVE In this study we investigated the relationship between heart rate variability (HRV) and respiration in healthy and probably asphyxiated infants using magnetocardiographic (MCG) recordings. METHODS Ten healthy and eight infants from pregnancies complicated by preeclampsia with indications of mild perinatal asphyxia were included in the study. All(More)
PURPOSE To evaluate the reproducibility of peripapillary retinal nerve fiber layer thickness (RNFLT) and ganglion cell complex (GCC) measurements made with the RTVue-100 Fourier-domain optical coherence tomography (OCT) device (Optovue, Inc., Fremont, CA) and to determine the influence of 4 factors: pupil dilation, subject age, experience in imaging(More)
PURPOSE To evaluate the diagnostic accuracy of retinal nerve fibre layer thickness (RNFLT), ganglion cell complex (GCC), and optic disc measurements made with the RTVue-100 Fourier-domain optical coherence tomography (OCT) to detect glaucoma in a Caucasian referral population. METHODS One randomly selected eye of 286 Caucasian patients (93 healthy, 36(More)
PURPOSE To investigate the ability of different parameters of the RTVue-100 Fourier-domain optical coherence tomograph (RTVue-OCT) to detect early glaucomatous progression. METHODS One eye of 17 healthy and 51 perimetric glaucoma patients was imaged prospectively at 6-month intervals for 1.5 to 3 years. Progression was determined by Octopus normal G2(More)
PURPOSE To compare repeatability of measurements of peripapillary retinal nerve fiber layer thickness (RNFLT) made using the RTVue-100 Fourier-domain optical coherence tomograph against repeatability of those made using scanning laser polarimetry with variable corneal compensation or enhanced corneal compensation (GDx-VCC and GDx-ECC, respectively).

We investigate the use of fractal analysis (FA) as the basis of a system for multiclass prediction of the progression of glaucoma. FA is applied to pseudo 2-D images converted from 1-D retinal nerve fiber layer data obtained from the eyes of normal subjects, and from subjects with progressive and nonprogressive glaucoma. FA features are obtained using a(More)
PURPOSE To compare sensitivity and specificity of retinal nerve fiber layer thickness (RNFLT) measurements made using RTVue-100 Fourier-domain optical coherence tomography (RTVue-OCT) and scanning laser polarimetry with variable (GDx-VCC) or enhanced compensation (GDx-ECC). METHODS One eye of each of 177 consecutive patients was imaged. Healthy (n=50) and(More)
PURPOSE To compare retinal nerve fiber layer thickness (RNFLT) and inner macula thickness changes measured with Fourier-domain optical coherence tomography (FD-OCT) and scanning laser polarimetry during the course of acute optic neuritis (ON). METHODS Nine eyes of 7 consecutive patients with multiple sclerosis (MS) were prospectively imaged from the onset(More)
Purpose. To compare long-term variability of retinal nerve fiber layer thickness (RNFLT) measurements made with the RTVue-100 Fourier-domain optical coherence tomograph (RTVue-OCT) and scanning laser polarimetry with variable (GDx-VCC) and enhanced (GDx-ECC) corneal compensation. Methods. One eye each of 110 Caucasian patients (17 healthy, 20 ocular(More)
Small supernumerary marker chromosomes (sSMCs) cannot be identified or characterized unambiguously by conventional cytogenetic banding techniques. Until recently, the large variety of marker chromosomes, as well as the limitations in their identification, have presented a diagnostic problem. In order to determine the origin of sSMCs, we used a variety of(More)
