The aim of the study was to evaluate macular thickness and macular volume in unilateral and bilateral exfoliation syndrome and to compare them with exfoliative glaucoma and control eyes using optical coherence tomography. This prospective study included 114 subjects (228 eyes) divided into 4 groups according to the presence of exfoliation: 30 patients with unilateral syndrome, 24 patients with ...

Exfoliated graphite (EG) refers to graphite that has a degree of separation of a substantial portion of the carbon layers in the graphite. Graphite nanoplatelet (GNP) is commonly prepared by mechanical agitation of EG. The EG exhibits clinginess, due to its cellular structure, but GNP does not. The clinginess allows the formation of EG compacts and flexible graphite sheet without a binder. The ...

Exfoliation syndrome (XFS) is an age-related disorder of the extracellular matrix that leads the production of abnormal fibrillar material that leads to elevated intraocular pressure and a relatively severe glaucoma. Exfoliation material is deposited in numerous ocular tissues and extraocular organs. XFS is associated with ocular ischemia, cerebrovascular disease, neurodegenerative disease and ...

AIM To study the course of exfoliation and simplex glaucoma with respect to intraocular pressure (IOP) regulation and visual field survival after primary trabeculectomy. METHODS Postoperative IOP regulation and complications were analysed prospectively in 95 patients. Mean follow up was 46 months. Visual field survival was studied by high pass resolution perimetry (HRP) in a subsample of 28 p...

Two different phases of the transition-metal dichalcogenide and molybdenum ditelluride (1T′-MoTe2 2H-MoTe2) were grown by chemical vapor transport. Oxygen-free surfaces generated exfoliation in air then analyzed x-ray photoelectron spectroscopy. High-resolution core valence Auger spectra acquired for both materials including Te 3d, 4d, MNN, Mo band spectra. Differences 3d peak positions that pr...

purpose: to compare body mass index (bmi) in patients with exfoliation syndrome (xfs) and a matched control group. methods: in a cross-sectional study, 84 patients with xfs (xfs group) and 84 persons without xfs (control group) were matched for sex and age and selected sequentially. bmi was compared in the two groups. patients with xfs with or without glaucoma and other complications were inclu...

polymer/clay nanocomposites are considered as a new subject of research in iran and the world. addition of a minimum amount of clay (2-5wt%) can improve the mechanical properties, enhance barrier properties and reduce flammability dramatically. polystyrene (ps) exhibits high strength, high modulus and excellent dimensional stability, but it has poor ductility, elongation, and flexural modulus. ...

Previous studies have shown that the exfoliation of graphitic carbon nitride (g-C3N4) is essential to obtain materials with good photocatalytic properties. However, in most works influence exfoliation...
