PURPOSE To examine associations between cardiovascular risk factors and age-related macular degeneration (AMD). METHODS A population-based, cross-sectional study of Caucasians aged 65-87 years was conducted in Norway in 2007/2008. Retinal photographs were graded for AMD. Multivariable logistic regression analyses were performed based on questionnaires(More)
OBJECTIVE The incidence of aneurysmal subarachnoid hemorrhage (aSAH) ranges from 4 to 10 per 100,000 person-years in most countries, and 30-day case fatality is high. The aim of this study was to estimate the incidence and case fatality of aSAH and to assess preictal predictors of survival in 2 large Norwegian population-based cohort studies. METHODS A(More)
BACKGROUND Subarachnoid hemorrhage (SAH) is a serious condition, occurring more frequently in females than in males. SAH is mainly caused by rupture of an intracranial aneurysm, which is formed by localized dilation of the intracranial arterial vessel wall, usually at the apex of the arterial bifurcation. The female preponderance is usually explained by(More)
OBJECTIVE Some risk factors for age-related macular degeneration (AMD) have been shown to act differently in women and men. The present study aims to investigate this disparity by examining associations between female hormones, reproductive history and AMD. METHODS Women aged 65-87 years were invited to this cross-sectional, population-based study in(More)
OBJECTIVES Life-style factors have been associated with the risk for aneurysmal subarachnoid hemorrhage (aSAH), but it is not clear whether body mass index (BMI) and serum lipids are associated with risk. We prospectively assessed these associations in two large population studies. METHODS A total of 65,526 participants in the Nord-Trøndelag Health Study(More)
INTRODUCTION The relationship between QT interval and cardiovascular disease is controversial. METHODS All male residents aged 20-61 years and female residents aged 20-56 years were invited to the Tromsø Study in 1986-1987. A total of 15,558 participants free of heart disease were prospectively followed over 20 years for myocardial infarction and death.(More)
PURPOSE To determine the prevalence of visual impairment, retinopathy and macular oedema, and assess risk factors for retinopathy in persons with diabetes. METHODS The present study included 514 participants with diabetes aged 46-87 years from the Tromsø Eye Study, a sub-study of the population-based Tromsø Study in Norway. Visual acuity was measured(More)
IMPORTANCE Identification of structural heart disease in asymptomatic individuals could allow early disease-modifying treatment. OBJECTIVE To examine whether echocardiographic screening in the general population improves long-term survival or reduces the risk of cardiovascular disease. DESIGN, SETTING, AND PARTICIPANTS We studied 6861 middle-aged(More)
PURPOSE To project the number of persons with late age-related macular degeneration (AMD) in Scandinavia through 2040. METHODS Age- and sex-specific prevalence rates of late AMD (choroidal neovascularization and geographic atrophy) from the European Eye Study and the Eye Diseases Prevalence Research Group were applied to the projected Danish, Norwegian(More)
This report describes a 59-year-old male with a renal artery pseudoaneurysm secondary to blunt trauma from a snowmobile accident. The patient presented with haematuria and flank pain, 9 years after the injury. This is the second longest interval between initial trauma and aneurysm rupture in published cases. The diagnosis was delayed because the doctors(More)
