PURPOSE To explore factors affecting the glaucoma diagnostic capability of macular thickness and circumpapillary retinal nerve fiber layer (cRNFL) thickness as determined by spectral domain-optical coherence tomography. METHODS Area under the curve (AUC) of the receiver operating characteristics (ROC) discriminating healthy from glaucomatous eyes was determined using 10 macular thickness and ...

introduction: the term glaucoma refers to a group of diseases that have a characteristic optic neuropathy with associated visual field loss in common. intraocular pressure has been considered to be the only causal factor for glaucoma and the only factor that can be manipulated to alter the course of the disease. but considering high intraocular pressure as the only factor responsible for glauco...

conclusions it seems that there is no significant relationship between the side-lying endurance test and abdominal muscles thickness. patients and methods a convenience sample of 55 subjects, aged 20 - 30 years, participated in this study. endurance of abdominal muscles was measured using side-lying endurance test in all subjects. ultrasound thickness measurement for the transverses abdominis (...

Background and purpose - Arthroscopic estimation of articular cartilage thickness is important for scoring of lesion severity, and measurement of cartilage speed of sound (SOS)-a sensitive index of changes in cartilage composition. We investigated the accuracy of optical coherence tomography (OCT) in measurements of cartilage thickness and determined SOS by combining OCT thickness and ultrasoun...

Scattering contrast measurements were performed on thin films of amorphous carbon and polycrystalline Au, as well as single-crystal MgO nanocubes. Based on the exponential absorption law, mass-thickness can be obtained within 10% accuracy by measuring the incident and transmitted intensities in the same image. For mass-thickness measurement of a thin amorphous specimen, a small collection semia...

Accurate thickness measurement of sheet-like structure such as articular cartilage in CT images is required in clinical diagnosis as well as in fundamental research. Using a conventional measurement method based on the zero-crossing edge detection (zero-crossings method), several studies have already analyzed the accuracy limitation on thickness measurement of the single sheet structure that is...

[Purpose] The purpose of this study was to examine the reliability of ultrasound measurements by analyzing the relative reliability and absolute reliability when measuring soft tissue thickness around the shoulder joint. [Subjects and Methods] Eleven healthy young adults (22 shoulders) participated in this study. Thickness of the supraspinatus tendon, subacromial bursa, and biceps tendon was me...

BACKGROUND Sufficient buccal bone is important for optimal esthetic results of implant treatment in the anterior region. It can be measured with cone beam computed tomography (CBCT), but background scattering and problems with standardization of the measurements are encountered. The aim was to develop a method for reliable, reproducible measurements on CBCTs. METHODS Using a new method, bucca...

Intraocular pressure has been considered to be the only causal factor for glaucoma and the only factor that can be manipulated to alter the course of the disease.

High-resolution transmission electron microscopy (HR-TEM) has been used as the ultimate method of thickness measurement for thin films. The appearance of phase contrast interference patterns in HR-TEM images has long been confused as the appearance of a crystal lattice by nonspecialists. Relatively easy to interpret crystal lattice images are now directly observed with the introduction of annul...
