BACKGROUND/AIMS With the increased efficacy of current therapy for wet age-related macular degeneration (AMD), better ways to detect wet AMD are needed. This study was designed to test the ability of three-dimensional contrast threshold Amsler grid (3D-CTAG) testing to distinguish wet AMD from dry AMD. METHODS Conventional paper Amsler grid and 3D-CTAG tests were performed in 90 eyes: 63 with...

age-related macular degeneration (amd) is the leading cause of blindness in old subjects. it is a multifactorial disease with both environmental and genetic factors playing some role in its pathogenesis. similar to many other genetic diseases, the inheritance pattern of amd does not fit into simple mendelian rules. these diseases are caused by the presence of multiple genetic factors and are ca...

PURPOSE To compare the ocular rigidity in vivo measurements of patients with age-related macular degeneration (AMD) and control subjects. DESIGN Prospective comparative clinical study. METHODS The pressure-volume relation and the ocular rigidity coefficient were compared among 32 patients with AMD (AMD group: 16 with neovascular and 16 with nonneovascular AMD) and 44 age-matched control pat...

800x600 years ago, it was thought that a genetic component was the fundamental cause of a number retinopathy diseases including age related macular degeneration (amd). since then, information has emerged about novel genes that contribute to various forms of amd and other retinopathies that have been eluding researchers for years. in the genetic sense, only the apoe 2 and 4 genes have been found...

background: we aimed here to investigate the association between alleles and genotypes of apoe and age-related macular degeneration (amd) development. materials and methods: after ophthalmological examination, 120 patients with confirmed amd and 120 healthy controls were enrolled in the study. the polymorphic segment of apoe gene was pcr-amplified and sequenced to determine the frequency distri...

age-related macular degeneration (amd) is the most common cause of irreversible vision loss and debilitating disease in old age, which involves the central retina/macula among elderly patients. the genetic and environmental factors have important role in this multifactorial disease. oxidative stress and dna damages would have important impact on the onset and progression of amd.  in this study,...

PURPOSE To assess vision-specific quality of life (QOL), based on abbreviated surveys derived from the National Eye Institute Visual Function Questionnaire (NEI-VFQ), in a cohort of United States women who participated in the Study of Osteoporotic Fractures. DESIGN Prospective, observational cohort study. METHODS Age-related macular degeneration (AMD) status, based on a 3-level classificati...

BACKGROUND Age-related macular degeneration (AMD) is a common disease causing visual impairment and blindness. Various gene variants are strongly associated with late stage AMD, but little is known about the genetics of early forms of the disease. This study evaluated associations of genetic factors and different AMD stages depending on unilateral and bilateral disease severity. METHODS In th...
