PURPOSE To investigate the association of lysyl oxidase like 1 (LOXL1) variants with exfoliation syndrome (XFS), exfoliation glaucoma (XFG), and primary open angle glaucoma (POAG) in a Turkish population. METHODS Two LOXL1 single nucleotide polymorphisms (SNPs), rs1048661 (R141L) and rs3825942 (G153D), were analyzed in 300 Turkish patients (100 patients with XFS, 100 patients with XFG, 100 pa...
Endothelin-1 concentration is increased in the aqueous humour of patients with exfoliation syndrome.
BACKGROUND /aim: Endothelin 1 (ET-1) is considered the most potent vasoconstrictor in the body and the eye. This molecule may play a significant role in the pathobiology of exfoliation syndrome (XFS), a disorder characterised by a progressive iris vasculopathy. The purpose of this study was to investigate the concentration of ET-1 in the aqueous humour of cataract patients with and without XFS....
PURPOSE Human eyes with exfoliation syndrome (XFS) exhibit a distinctive pattern of iris transillumination defects that are recapitulated in Lyst mutant mice carrying the beige allele. The purpose of this study was to determine the anatomic basis for Lyst-mediated transillumination defects, test whether Lyst mutant mice develop other features of XFS, and describe the molecular basis of the beig...
PURPOSE To evaluate the reproducibility of intraocular pressure (IOP) peaks and fluctuations detected during the water-drinking test (WDT) in patients with exfoliation syndrome (XFS) and exfoliative glaucoma (XFG). METHODS This prospective study included 34 XFS and 30 XFG patients. Each patient was evaluated twice, with the two WDTs performed on a 30-day interval. We recorded IOP peak (highes...
Exfoliation syndrome (XFS) is a common, age-related, systemic fibrillinopathy. It greatly increases risk of exfoliation glaucoma (XFG), a major worldwide cause of irreversible blindness. Coding variants in the lysyl oxidase-like 1 (LOXL1) gene are strongly associated with XFS in all studied populations, but a functional role for these variants has not been established. To identify additional ca...
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 ...
PURPOSE To increase knowledge of the biochemical composition of lenticular exfoliation material (XFM) by using proteomic approaches. METHODS Anterior lens capsules from patients with and without exfoliation syndrome (XFS) were homogenized in formic acid and subjected to cyanogen bromide (CNBr) cleavage, and the pattern of chemically generated fragments was compared by SDS-PAGE after silver st...
PURPOSE To investigate whether the single nucleotide polymorphisms (SNPs) of the LOXL1 gene associated with exfoliation syndrome (XFS) and exfoliative glaucoma (XFG) are different in XFS/XFG patients with and without cardiovascular disease (CVD); and to compare the allele frequencies in XFS/XFG with those in ischemic cerebrovascular disease (stroke), in the Hungarian population. METHODS G153D...
PURPOSE Exfoliation syndrome (XFS) is an age-related ocular condition that is characterized by the accumulation of fibrillogranular extracellular material in intra- and extraocular tissues. The purpose of the present study was to identify the genetic basis of XFS in a large Finnish family. METHODS A genome-wide scan with 1000 microsatellite markers was performed in an extended family from an ...
PURPOSE To test the hypothesis that autophagy dysfunction is involved in exfoliation syndrome (XFS), a systemic disorder of extracellular elastic matrices that causes a distinct form of human glaucoma. METHODS Fibroblasts derived from tenon tissue discards (TFs) from filtration surgery to relieve intraocular pressure in XFS patients were compared against age-matched TFs derived from surgery i...
