PURPOSE To compare outcomes in exfoliation glaucoma versus primary open-angle glaucoma (POAG) after ab interno trabeculectomy alone (Trabectome) or in combination with cataract surgery and intraocular lens (IOL) implantation. SETTING Trabectome Study Group institutions. DESIGN Prospective nonrandomized cohort study. METHODS Outcomes included intraocular pressure (IOP), glaucoma medication...

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 ...

Graphene has attracted intense interest due to its exceptional physical and chemical properties as well as its wide potential applications. For applications of two-dimensional graphene, commercially viable sources are necessary. Liquid-phase exfoliation graphite is one of the most promising economical mothed for the mass production of graphene. A number of methods have been developed to achieve...

Understanding and exploiting the remarkable optical and electronic properties of phosphorene require mass production methods that avoid chemical degradation. Although solution-based strategies have been developed for scalable exfoliation of black phosphorus, these techniques have thus far used anhydrous organic solvents in an effort to minimize exposure to known oxidants, but at the cost of lim...

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...

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...
