BACKGROUND Vitreo-retinal diseases are among the leading causes of visual impairment and blindness worldwide. This study reports the prevalence and pattern of vitreo-retinal diseases in the Bhaktapur Glaucoma Study (BGS), a population based study conducted in Nepal. METHODS BGS was a population based cross-sectional study involving 4800 subjects aged 40(More)
PURPOSE Recently, several studies have investigated genetic associations between Cytochrome P450 (CYP1B1), Endothelial nitric oxide synthase (eNOS), and Neurotrophin-4 (NTF4) with primary angle-closure glaucoma (PACG) in various ethnic groups. We investigated the association of these candidate genes with PACG in samples from Australia and Nepal. METHODS A(More)
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(More)
BACKGROUND Cataract and glaucoma are the major causes of blindness in Nepal. Bhaktapur is one of the three districts of Kathmandu valley which represents a metropolitan city with a predominantly agrarian rural periphery. This study was undertaken to determine the prevalence of visual impairment, cataract surgery and awareness of cataract and glaucoma among(More)
PURPOSE Genetic variation in the hepatocyte growth factor (HGF) gene has recently been associated with hyperopia, which is a known risk factor for primary angle closure glaucoma (PACG). This study aimed to investigate whether genetic variation in HGF is associated with primary angle closure glaucoma in the Nepalese population. METHODS One hundred six(More)
PURPOSE To investigate the underlying genetic variation between candidate genes and primary angle closure glaucoma (PACG) in both Nepalese and Australian populations. METHODS A total of 213 patients with PACG (106 Nepalese and 107 Australian) and 492 age and sex matched controls (204 Nepalese and 288 Australian) were included in the current study. Three(More)
BACKGROUND Glaucoma is a major cause of blindness worldwide and an increasingly significant global health problem. Glaucoma prevention and management efforts have been challenging due to inherent difficulty in developing a simple and cost-effective screening plan, limited access to health care and educational resources, poverty, and inadequate knowledge of(More)
BACKGROUND Early detection can reduce irreversible blindness from retinal diseases. This study aims to assess the intra- and inter-rater agreement of retinal pathologies observed on fundus photographs between an ophthalmologist and two-mid level ophthalmic personnel (MLOPs). METHOD A population-based, cross-sectional study was conducted among subjects 60(More)
BACKGROUND Cataract and glaucoma are both common conditions and are often present in the same patient. The incidence of these diseases increases with age. Besides vision impairment, these diseases are associated with decrement in quality of life (QOL). OBJECTIVE To study the effect of phacoemulsification surgery on various parameters in patients with(More)
