purpose: to determine the correlation between body mass index (bmi) and exudative age-related macular degeneration (armd). methods: this case-control study was conducted on 60 patients with exudative armd and 60 controls, both aged over 50. age, sex, cigarette smoking and blood pressure were evaluated beside bmi. data analysis was performed by spss software, version 9.0 using pearson chi square...
Age-related macular degeneration (AMD) is a leading cause of visual impairment and blindness in the elderly whose etiology remains largely unknown. Previous studies identified chromosome 1q32 as harboring a susceptibility locus for AMD. We used single-nucleotide polymorphisms to interrogate this region and identified a strongly associated haplotype in two independent data sets. DNA resequencing...
Age-related macular degeneration (AMD) is the leading cause of visual loss in the developed World in patients over age 55. Therapeutic advances in the dry (non-exudative) form of AMD have been very modest with a protective role demonstrated for supplemental anti-oxidant vitamin therapy in patients showing high risk characteristics for future progression. In contrast, a major advance in the trea...
Excess iron induces tissue damage and is implicated in age-related macular degeneration (AMD). Iron toxicity is widely attributed to hydroxyl radical formation through Fenton's reaction. We report that excess iron, but not other Fenton catalytic metals, induces activation of the NLRP3 inflammasome, a pathway also implicated in AMD. Additionally, iron-induced degeneration of the retinal pigmente...
"Geographic atrophy" is a concise term that has been firmly established for the description of the end-stage manifestation of nonexudative age-related macular degeneration (AMD). "Geographic lesions" resembling sharply demarcated continents on a map have been originally described in the German literature in 1854 (landkartenartiger/inselförmiger Zungenfratt) for a manifestation later called "geo...
OBJECTIVE To examine the age- and sex-specific prevalence of age-related maculopathy (ARM) and age-related macular degeneration (AMD) in citizens of Reykjavik, Iceland, who were 50 years and older. DESIGN Random sample, cross sectional. MATERIALS AND METHODS Response rate was 75.8%. The presence and severity of various characteristics of drusen and pigmentary changes that are typical of ARM...
Age-related macular degeneration (AMD) is the leading cause of blindness in industrial countries. Vision loss caused by AMD results from geographic atrophy (dry AMD) and/or choroidal neovascularization (wet AMD). Presently, the etiology and pathogenesis of AMD is not fully understood and there is no effective treatment. Oxidative stress in retinal pigment epithelial (RPE) cells is considered to...
PURPOSE There is good evidence that oxidative stress is involved in the pathogenesis of age-related macular degeneration (AMD). Because AMD has risk factors and histopathology similar to with atherosclerosis, we hypothesized that oxidized phospholipids, which contribute to the pathogenesis of atherosclerosis, would accumulate in the eyes of AMD patients. To test this hypothesis, we investigated...
