PURPOSE To determine whether or not there is an association of the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism with disease in cohorts of primary open-angle glaucoma (POAG) and primary closed-angle glaucoma (PCAG) from Pakistan. METHODS This was a prospective study consisting of 150 patients (90 POAG and 60 PCAG) and 70 control(More)
PURPOSE To investigate the methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C genotypes and plasma concentrations of total homocysteine (tHcy) in Pakistani patients with primary open angle glaucoma (POAG) and primary closed angle glaucoma (PCAG). METHODS This was a prospective case-control study. A total of 295 patients (173 POAG, 122 PCAG) and(More)
PURPOSE Matrix metalloproteinases (MMPs) play an important role in remodeling of the extracellular matrix during development and growth of various tissues including the eye. Various functional polymorphisms in MMPs have been implicated in the pathogenesis of different types of glaucoma. The aim of the present study was to investigate the role of various(More)
PURPOSE Despite the different etiology of primary open angle glaucoma (POAG), primary angle closure glaucoma (PACG), and pseudoexfoliative glaucoma (PEXG), several studies have suggested that these forms of glaucoma have overlapping genetic risk factors. Therefore, the aim of this study was to evaluate the role of genetic variants recently associated with(More)
Purpose: Three genes VSX1, HGF and LOX have been previously reported to be causative of keratoconus (KC) in different populations. In the current study we investigated the role of these genes in three autosomal recessive Pakistani families and 100 sporadic KC cases from Pakistan. Methods: Mutation analysis of VSX1 gene was done by Sanger sequencing of three(More)
PURPOSE A novel application of pulsed electronic speckle pattern interferometry (PulseESPI) techniques in important corneal elasticity measurements is presented in this pilot study. For laser-ablative procedures like laser-assisted in situ keratomileusis, it has been found that elastic properties of the cornea have a role in the outcome of corneal(More)
BACKGROUND Recently nonsynonymous coding variants in the ankyrin repeats and suppressor of cytokine signaling box-containing protein 10 (ASB10) gene were found to be associated with primary open angle glaucoma (POAG) in cohorts from Oregon and Germany, but this finding was not confirmed in an independent cohort from Iowa. The aim of the current study was to(More)
