TLDR
Two nonsynonymous SNPs in exon 1 of the gene LOXL1 explain the association with glaucoma, and the data suggest that they confer risk of XFG mainly through exfoliation syndrome (XFS).Abstract:
Glaucoma is a leading cause of irreversible blindness A genome-wide search yielded multiple single-nucleotide polymorphisms (SNPs) in the 15q241 region associated with glaucoma Further investigation revealed that the association is confined to exfoliation glaucoma (XFG) Two nonsynonymous SNPs in exon 1 of the gene LOXL1 explain the association, and the data suggest that they confer risk of XFG mainly through exfoliation syndrome (XFS) About 25% of the general population is homozygous for the highest-risk haplotype, and their risk of suffering from XFG is more than 100 times that of individuals carrying only low-risk haplotypes The population-attributable risk is more than 99% The product of LOXL1 catalyzes the formation of elastin fibers found to be a major component of the lesions in XFGread more

Gene finding in primary open-angle glaucoma.
TL;DR: There is extensive evidence that there is a genetic component to developing primary open-angle glaucoma (POAG), and unraveling this genetic component might clarify the pathophysiology of the disease and greatly assist in treatment and prevention of visual loss of many thousands of individuals.

TL;DR: Prevalence of PEX was higher in rural population and baseline OHT was a significant factor for conversion to glaucoma, and rates of cataract surgery were higher in subjects with PEX.

TL;DR: This review summarises the important properties of successful biomarkers and surrogates, and relates this to how intraocular pressure, visual field testing, and imaging have been refined to improve early diagnosis and progression analysis of glaucoma patients.

The genetic associations of rhegmatogenous retinal detachment and ectopia lentis
TL;DR: A clear genotype-phenotype correlation between isolated EL and its most important causative gene: ADAMTSL4 is established, suggesting that mutations in this gene result in a more severe phenotype than other genes causing EL.

Statistical Aspects of the Analysis of Data From Retrospective Studies of Disease
Nathan Mantel,William Haenszel +1 more
TL;DR: In this paper, the role and limitations of retrospective investigations of factors possibly associated with the occurrence of a disease are discussed and their relationship to forward-type studies emphasized, and examples of situations in which misleading associations could arise through the use of inappropriate control groups are presented.

TL;DR: Estimates from data on low vision and blindness as defined in the International statistical classification of diseases, injuries and causes of death, 10th revision show cataract remains the leading cause of visual impairment in all regions of the world, except in the most developed countries.

TL;DR: The performance of the genomic control method is quite good for plausible effects of liability genes, which bodes well for future genetic analyses of complex disorders.

The definition and classification of glaucoma in prevalence surveys
TL;DR: This review describes a scheme for diagnosis of glaucoma in population based prevalence surveys that makes provision for diagnosing glauca in eyes with severe visual loss where formal field testing is impractical, and for blind eyes in which the optic disc cannot be seen because of media opacities.

TL;DR: A gene encoding a trabecular meshwork protein (TIGR) mapped to the narrowest disease interval by STS content and radiation hybrid mapping and will aid in early diagnosis of glaucoma.
