Red blood cell antioxidant enzymes in age-related macular degeneration.
AIMS/BACKGROUND Oxidative damage has been proposed to be involved in the pathogenesis of age-related macular degeneration (ARMD). The purpose of this study was to evaluate whether red blood cell antioxidant enzyme activity correlates with severity of aging maculopathy in affected individuals. METHODS Blood samples were obtained from 54 patients with varying severity of aging maculopathy and 1...
متن کاملAssociation of Age-Related Macular Degeneration with Erythrocyte Antioxidant Enzymes Activity and Serum Total Antioxidant Status
The aim was to estimate association of the oxidative stress with the occurrence of age-related macular degeneration (AMD). The activities of erythrocyte antioxidant enzymes: superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) and additionally serum total antioxidant status (TAS) were used as indicators of the oxidative stress level. 57 AMD patients (32 early and 25 late ...

amd بیماری تحلیل شبکیه است که عامل اصلی کوری در افراد بالای 55 سال در جهان غرب به شمار می-رود. در اثر این بیماری، لیپوپروتئین ها در شبکیه تجمع پیدا کرده و رگ زایی القاء می شود. ثابت شده است که عوامل ژنوتوکسیک محیطی مثل سیگار کشیدن، رژیم غذایی و نور در افراد پیر با زمینه ی ژنتیکی مستعد در بروز بیماری دخیل می باشند. بنابراین ما یک مطالعه ی مـورد- شاهـدی را ترتیب دادیم که شـامل 112 فرد مبتلا به am...
the genetics of age-related macular degeneration
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...
متن کاملMeasurement of Choroidal Neovascular Area in Age-Related Macular Degeneration using Modified Otsu’s Thresholding Method
Introduction: Age-related Macular Degeneration (AMD) is one of the most important causes of irreversible blindness in the developed world and prevents the affected person from performing simple tasks such as reading, driving and facial recognition. In the AMD, new blood vessels grow underneath the retina in a process called choroidal neovascularisation (CNV). There ...
