Pseudo exfoliation syndrome (XFS) is an age-related, generalized disorder of the extracellular matrix characterized by the production and progressive accumulation of an abnormal fibrillar extracellular material in many ocular tissues and is the most common identifiable cause of openangle glaucoma worldwide. Exfoliation syndrome plays an etiologic role in open-angle glaucoma, angle-closure glauc...
PURPOSE A recent large genome-wide association study (GWAS) identified multiple variants associated with primary angle-closure glaucoma (PACG). The present study investigated the role of these variants in two cohorts with PACG recruited from Australia and Nepal. METHOD Patients with PACG and appropriate controls were recruited from eye clinics in Australia (n = 232 cases and n = 288 controls)...
In recent papers (Lowe, I968, I969a) it was shown that in normal eyes, lens position and thickness were coordinated with axial length and radius of corneal curvature, whereas in eyes with primary angle-closure glaucoma these correlations were lacking. Throughout adult life, lenses increase in thickness at the same rate in normal eyes and those with angle-closure glaucoma, but no change could be...
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; per-allele effect size = -0.045 mm, P...
Nanophthalmos, uveal effusion syndrome, and acute angle closure glaucoma (ACG) can present as a continuum in a patient, as is described here. This patient's angle closure was thought to be caused by idiopathic uveal effusion syndrome, and while there are no generally accepted diagnosis criteria for nanophthalmos, our patient fulfilled the criteria as defined by Wu.10 To prevent development of f...
Most severe eye diseases and injuries ultimately require intervention by an ophthalmologist. The urgency of referral depends on various factors, including level of vision loss, duration of symptoms, and presence of comorbid diseases. Of special importance are five acute eye problems in which emergency management by primary care physicians can be critical to visual outcome: high-velocity injurie...
In the last few years the classification of angle-closure glaucoma has undergone revision. This is a result of population research in regions where angle-closure glaucoma is a major cause of blindness. Several studies have shown that most cases of angle-closure that cause glaucomatous optic neuropathy occur without the symptoms that Western ophthalmologists associate with episodes of acute angl...
background: it has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. we aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes. methods: twenty eight patients with acute attack of primary angle closure were ...
INTRODUCTION To describe the optic disc, visual field and ocular characteristics of a consecutive cohort of Asian patients with chronic primary angle-closure glaucoma (CPACG), and compare them with those having primary open-angle glaucoma (POAG). METHODS In a prospective comparative case series of new patients with POAG or CPACG in Singapore, all patients underwent visual acuity assessment, s...
