Age-related macular degeneration (AMD) is a leading cause of irreversible visual impairment in the world. Advanced AMD can be divided into wet AMD (choroidal neovascularization) and dry AMD (geographic atrophy, GA). Drusen is characterized by deposits in the macula without visual loss and is an early AMD sign in the Caucasian population. rs11200638 in the promoter of HTRA1 has recently been sho...

Anthropogenic marine debris (AMD) is frequently studied on sandy beaches and occasionally in coastal waters, but links between these two environments have rarely been studied. High densities of AMD were found in coastal waters and on local shores of a large bay system in northern-central Chile. No seasonal pattern in AMD densities was found, but there was a trend of increasing densities over th...

PURPOSE To determine the association between complement factor H (CFH) polymorphism T1277C (tyrosine-402 --> histidine-402) and phenotypic variations of age-related macular degeneration (AMD). DESIGN Cross-sectional observational study. PARTICIPANTS Subjects with dry or wet AMD and a control population consisting of age-matched non-AMD subjects from 2 clinical facilities examined during the...

PURPOSE To investigate the telescope use and driving patterns of bioptic drivers with age-related macular degeneration (AMD). METHODS A questionnaire addressing telescope use and driving patterns was administered by telephone interview to three groups of bioptic drivers: AMD (n = 31; median 76 years); non-AMD first licensed with a bioptic (n = 38; 53 years); and non-AMD first licensed without...

Neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) are leading causes of irreversible blindness in developed countries. In this study, we investigated the association of single nucleotide polymorphisms (SNPs) in the serpin peptidase inhibitor, clade G, member 1 (SERPING1) gene with neovascular AMD and PCV. Two haplotype-tagging SNPs, rs1005510 and rs1...

BACKGROUND/AIM To compare the cognitive functions and define the frequency of Alzheimer disease (AD) between participants with and without age-related macular degeneration (AMD). MATERIALS AND METHODS Fifty-nine patients with late-stage AMD (74.3 ± 7.3 years) and 49 age-, sex-, and education-matched control subjects were compared for the presence of AD according to the guidelines of the Natio...

BACKGROUND HMG Co-A reductase inhibitors are ubiquitous in our community yet their potential role in age-related macular degeneration (AMD) remains to be determined. METHODOLOGY/PRINCIPAL FINDINGS OBJECTIVES To evaluate the effect of simvastatin on AMD progression and the effect modification by polymorphism in apolipoprotein E (ApoE) and complement factor H (CFH) genes. DESIGN A proof of...

PURPOSE We compared across age-related macular degeneration (AMD) subtypes the effect of AMD risk variants, their predictive power, and heritability. METHODS The prevalence of AMD was estimated among active non-Hispanic white Kaiser Permanente Northern California members who were at least 65 years of age as of June 2013. The genetic analysis included 5,170 overall AMD cases ascertained from e...

BACKGROUND Age-related macular degeneration (AMD) is a primary cause of blindness among the elderly in developed countries. The nature of AMD is complex and includes both environmental and hereditary factors. Oxidative stress is thought to be essential in AMD pathogenesis. Iron is suggested to be implicated in the pathogenesis of AMD through the catalysis of the production of reactive oxygen sp...
