age related macular degeneration (amd) is the most common cause of visual impairment in the population above 64 years of age in developed countries. most cases of severe vision loss due to amd are caused by exudative changes in the macula. extensive research on amd has led to advances in its prophylaxis and treatment in recent years. photodynamic therapy (pdt) was developed in late 1990's ...

purpose: to investigate the effect of ccl2c-2512t polymorphism on age-related macular degeneration (amd). methods: this study enrolled 48 patients originating from northeast of iran who suffered from dry type amd. the association of c-2518t in the promoter region of ccl2 gene was investigated using polymerase chain reaction (pcr) and restriction fragment length polymorphism (rflp). control grou...

background: age-related macular degeneration (amd) is one of the leading causes of visual loss among people aged 65 yr and older. the pathophysiology of amd is poorly understood. the purpose of this study was to evaluate the relationship between serum lipid concentrations and age-related macular degeneration. methods: in this case-control study, total cholesterol (tch), low density lipoprotein ...

purpose : to evaluate the toxic retinal effects of intravitreal bevacizumab used for the treatment of exudative age-related macular degeneration (amd) using ganzfeld electroretinography (g-erg) methods : in this prospective comparative interventional study, 23 patients with active choroidal neovascularization (cnv) associated with amd were enrolled. patients were received intravitreal injection...

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...

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...

purpose : to offer a semi-automatic algorithm to determine the area of angiographic hyperfluorescence methods : the proposed algorithm included wavelet filter, histogram equalization and modified otsu thresholding. hyperfluorescent area of 30 angiographic images obtained from patients with leaking choroidal neovascularization (cnv) and diabetic retinopathy were evaluated and the results were co...

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...
