Primary angle closure glaucoma (PACG) is a major cause of blindness worldwide. We conducted a genome-wide association study including 1,854 PACG cases and 9,608 controls across 5 sample collections in Asia. Replication experiments were conducted in 1,917 PACG cases and 8,943 controls collected from a further 6 sample collections. We report significant(More)
Anterior chamber depth (ACD) is a key anatomical risk factor for primary angle closure glaucoma (PACG). We conducted a genome-wide association study (GWAS) on ACD to discover novel genes for PACG on a total of 5,308 population-based individuals of Asian descent. Genome-wide significant association was observed at a sequence variant within ABCC5 (rs1401999;(More)
PURPOSE To evaluate the efficacy and safety of deep sclerectomy in childhood glaucoma. METHODS A prospective cohort of 120 children presenting with glaucoma to King Abdul Aziz University Hospital (KAUH) was subjected to nonpenetrating deep sclerectomy surgery (NPDS). Eventually, 57 patients had macro perforation and converted to penetrating deep(More)
BACKGROUND To investigate whether the c.47T > C mutation in the manganese superoxide dismutase gene (Mn-SOD) is a risk factor for primary open angle glaucoma (POAG) in the Saudi population. MATERIALS AND METHODS A cohort of 226 unrelated POAG patients and 403 unrelated control subjects from Saudi Arabia were genotyped for a single nucleotide polymorphism(More)
PURPOSE To investigate whether major single nucleotide polymorphisms (SNPs) in the LOXL1 gene associated with pseudoexfoliation glaucoma are associated with primary open angle glaucoma (POAG) in the Saudi Arabian population. METHODS The regions of the LOXL1 gene associated with pseudoexfoliation glaucoma, encompassing the three common SNPs, (rs1048661,(More)
To Investigate whether the g.4760C>T polymorphism in the promoter region of the catalase gene (CAT) is a risk factor for primary angle closure glaucoma (PACG) in the Saudi population. 138 unrelated PACG patients and 403 unrelated control subjects from Saudi Arabia were genotyped for a single nucleotide polymorphism (SNP; rs1001179; g.4760C>T) utilizing(More)
The trabectome is a novel form of ab interno trabeculectomy that ablates and remove the trabecular meshwork and the inner wall of Schlemm's canal and subsequently expose the natural drainage pathway (the collector channels) to aqueous humor. Complications associated with the trabectome are few and among them is transient hypotony. We report a case of a(More)
Exfoliation syndrome (XFS) is the most common recognizable cause of open-angle glaucoma worldwide. To better understand the etiology of XFS, we conducted a genome-wide association study (GWAS) of 1,484 cases and 1,188 controls from Japan and followed up the most significant findings in a further 6,901 cases and 20,727 controls from 17 countries across 6(More)
OBJECTIVE To investigate the number and characteristics of patients attending the Accident/Emergency (A/E) Department of a tertiary care hospital in Riyadh, and to determine their route of referral, and pattern of ocular emergency cases. METHODS A retrospective study was carried out using the records and history of all patients attending the A/E at King(More)
Primary open angle glaucoma (POAG), a major cause of blindness worldwide, is a complex disease with a significant genetic contribution. We performed Exome Array (Illumina) analysis on 3504 POAG cases and 9746 controls with replication of the most significant findings in 9173 POAG cases and 26 780 controls across 18 collections of Asian, African and European(More)
