It is a matter of considerable clinical interest whether removal of the lens causes regression of pseudoexfoliation of the lens capsule. Before the paper by Dvorak-Theobald (I954), pseudoexfoliation of the lens capsule was often confused with true exfoliation, and it was suggested that lens extraction caused the condition to disappear (Irvine, I940; Gradle and Sugar, I947). After this paper app...

The first cases of pseudoexfoliation of the lens to be found in Australian Aborigines are reported. The prevalence rate in the communities in central Australia is 1-3% and for those 61 years and older is 16-3%. Within the limits of our assessment glaucoma was an associated finding in 8-1% of these cases. A high incidence of old trachoma, previous trauma, and Labrador keratopathy was also noted ...

The experimental exfoliation of layered, ternary transition-metal carbide and nitride compounds, known as MAX phases, into two-dimensional (2D) nanosheets, is a great development in the synthesis of novel low-dimensional inorganic systems. Among the MAX phases, Mo-containing ones might be considered as the source for obtaining Mo2C nanosheets with potentially unique properties, if they could be...

PURPOSE To visualize structural alterations of the cornea, iris, and lens in patients with exfoliation syndrome (XFS) using a noncontact in vivo laser scanning confocal microscope and to correlate these with the clinical features. METHODS The cornea, iris, and lens of 30 eyes with XFS were imaged using the Rostock Cornea Module of Heidelberg Retina Tomograph II (50x noncontact Nikon lens, an ...

OBJECTIVE To identify geographic and climatic risk factors associated with exfoliation syndrome (ES). METHODS A retrospective study of 626 901 eye care recipients, dating from 2001 to 2007 from 47 US states in a managed care network. Incident ES cases-patients (N = 3367) were identified by using billing codes. We assessed the risk of ES by geographic latitude tier in the continental United St...

PURPOSE To investigate the contactin-associated protein-like 2 (CNTNAP2) gene for single-nucleotide polymorphisms (SNPs) in Japanese patients with the exfoliation syndrome (XFS). METHODS One hundred and eight unrelated Japanese patients with the XFS, and 199 normal controls were studied. Genomic DNA was extracted from the leukocytes of the peripheral blood, and 8 SNPs, rs826802, rs1404699, rs...

True exfoliation of the lens capsule is known to be associated with glassblower's cataract, which is caused by extended exposure to excessive heat. Furthermore, inflammation and trauma are also considered to be predisposing factors. We report two cases of true exfoliation that were confirmed after cataract surgery. Neither patient exhibited true exfoliation before cataract surgery. In addition,...

This study demonstrates a facile, mild and environmentally-friendly sustainable (soft processing) approach for the efficient electrochemical exfoliation of graphite using a sodium hydroxide/hydrogen peroxide/water (NaOH/H2O2/H2O) system that can produce high-quality, anodic few-layer graphene nanosheets in 95% yield at ambient reaction conditions. The control experiment conducted using NaOH/H2O...
