The continental collision and subduction between the North China Craton Yangtze Plate resulted in complex multistage tectonic episodes of Tanlu fault zone. To adequately understand geodynamic processes collision, we construct a high-resolution shear-wave velocity model crust uppermost mantle using full-wave ambient noise tomographic method based on new broadband dense seismic array across Our r...

The pre-ocular tear film is a complex biochemical structure produced by the lacrimal glands and epithelial cells on the ocular surface. Clinical syndromes of ocular irritation may result from deficiencies in one or more of these layers. At a recent dry eye workshop at the National Eye Institute, dry eye conditions were classified into those with adequate aqueous tear production and those with a...

This study was performed to evaluate the changes of tear film and ocular surface caused by smoking. Symptom scoring, tear film break-up time (BUT), basal tear secretion test, corneal sensitivity test, keratoepitheliopathy scoring, and conjunctival impression cytology were performed in 29 smokers (58 eyes) and 26 non-smokers (52 eyes). Tear film BUT, basal tear secretion, corneal sensitivity, an...

Rabbit tear lysozyme was detected in low concentration in rabbit tears collected without any stimulation. Quantitation of rabbit tear lysozyme was found possible through the use of sensitive techniques that measure its specific enzymic activity on the bacterial cell walls of Micrococcus lysodeikticus. Rabbit tear lysozyme has an electrophoretic mobility identical to that of hen egg-white lysozy...

PURPOSE To describe various types of anterior capsular tears and an early diagnostic, flap motility, as a sign of posterior capsular rupture following posterior extension of radial tears. DESIGN This was a prospective study carried out in 4,331 eyes that underwent phacoemulsification in a private practice setting from April 2015 to February 2016. Twenty six consecutive cases of anterior capsu...

The fluorescein tear film break-up test is a common tear film stability test for dry eye diagnosis. This test requires applying fluorescein sodium drops to a tear film to observe the tear film break-up. However, this test is limited by using the fluorescein sodium drops, which can induce reflex tearing and reduce the reliability of the diagnosis results. This paper proposes that tear film evapo...

PURPOSE To determine the repeatability of real-time optical coherence tomography (OCT) measurements of tear film thickness (TFT) and variables of tear film menisci. METHODS Forty eyes were imaged with a custom-built, real-time OCT to obtain heights, curvatures, and cross-sectional areas of upper and lower tear menisci simultaneously. The central TFT was indirectly determined as the difference...

PURPOSE To determine the clinical features of tear fluid signs associated with filtration blebs via three-dimensional anterior segment optical coherence tomography (3D AS-OCT). METHODS In total, 152 eyes (130 patients) with glaucoma that underwent trabeculectomy with mitomycin C were evaluated retrospectively. We investigated tear fluid signs associated with filtration blebs, using 3D AS-OCT ...

PURPOSE Floppy eyelid syndrome (FES) presents nonspecific ocular surface irritation. The hypothesis for the current study was that one contributing factor is the abnormality in tear film dynamics. METHODS Sixteen patients with FES were consecutively examined. Tear film dynamics were evaluated by kinetic tear interference images, infrared thermometry, water evaporation rate, tear break-up time...
