Existe-t-il une place pour la micronutrition dans les glaucomes ?
2009
National audience; Lamicronutrition a pris ses marques en ophtalmologie principalement dans la dégénérescence maculaire liée à l'âge (DMLA), mais aussi dans les maladies de la surface oculaire. Pour les glaucomes, le stade actuel est plutôt celui de la réflexion qui permet de construire un rationnel à partir des hypothèses physiopathogéniques des glaucomes. Dans ce court article, nous évoquerons ces hypothèses et nous citerons les études animales et chez l'homme qui existent déjà, en insistant sur le rôle des lipides et des acides gras essentiels.
Molecular biomarkers in glaucoma
2013
The seventh annual ARVO/Pfizer Ophthalmic Research Institute conference was held Friday and Saturday, April 29 and 30, 2011, at the Fort Lauderdale Hyatt Regency Pier 66, Fort Lauderdale, Florida. The conference, funded by The ARVO Foundation for Eye Research through a grant from Pfizer Ophthalmics, provided an opportunity to gather experts from within and outside ophthalmology to determine the state of knowledge pertaining to molecular biomarkers associated with glaucoma, as well as the methods to identify and validate them to predict (a) those who would be susceptible to development of glaucoma; (b) markers that will enable prediction of glaucoma progression; and (c) markers that will pre…
A large cross-ancestry meta-analysis of genome-wide association studies identifies 69 novel risk loci for primary open-angle glaucoma and includes a …

AbstractWe conducted a large multi-ethnic meta-analysis of genome-wide association studies for primary open-angle glaucoma (POAG) on a total of 34,179 cases vs 349,321 controls, and identified 127 independent risk loci, almost doubling the number of known loci for POAG. The majority of loci have broadly consistent effect across European, Asian and African ancestries. We identify a link, both genome-wide and at specific loci, between POAG and Alzheimer’s disease. Gene expression data and bioinformatic functional analyses provide further support for the functional relevance of the POAG risk genes. Several drug compounds target these risk genes and may be potential candidates for developing no…
SLC23A2 Gene Variation, Vitamin C Levels, and Glaucoma
2014
Abstract Primary open-angle glaucoma (POAG) is a multifactorial disease in which both genetic and environmental factors are involved. Among the environmental factors associated with POAG, nutritional factors are particularly important since nutrition is essential for maintaining good health. Researchers can study the interactions between nutrition and genes by means of nutritional genomics, but nutrigenomics studies regarding eye diseases are very scarce. This research group recently published one of the first studies on nutrigenomics in POAG. It was found that the rs1279683 polymorphism in the SLC23A2 gene, which encodes a vitamin C transporter, is associated with a higher risk of POAG. Si…
Genetic polymorphism related to exfoliative glaucoma is also associated with primary open-angle glaucoma risk
2014
Background To investigate the possible association of the rs2165241 polymorphism (C > T) in LOXL1 gene with the risk of primary open-angle glaucoma in a Mediterranean population. Methods The analysis of genetic polymorphisms was performed by standard TaqMan allelic discrimination technique, using a 7900HT Sequence Detection System (Applied Biosystems). Results In a recessive genetic model, the T allele of the rs2165241 polymorphism was significantly associated with the risk of primary open-angle glaucoma (TT vs. CC: odds ratios = 2.19, 95% confidence interval = [1.33–3.62]). After multivariate logistic regression model adjusted by age and weight, the magnitude of the association decreased b…

Strategies to Reduce Oxidative Stress in Glaucoma Patients
2018
Background Primary open-angle glaucoma (POAG) is a multifactorial pathology involving a variety of pathogenic mechanisms, including oxidative/nitrosative stress. This latter is the consequence of the imbalance between excessive formation and insufficient protection against reactive oxygen/nitrogen species. Objective Our main goal is to gather molecular information to better managing pathologic variants that may determine the individual susceptibility to oxidative/nitrosative stress (OS/NS) and POAG. Method An extensive search of the scientific literature was conducted using PUBMED, the Web of Science, the Cochrane Library, and other references on the topic of POAG and OS/NS from human and a…
