Amsler grid distortion signals AMD
Oct 17, 2009
A new rarebit vision test device is described and preliminary data indicate that it may be suitable for screening for the presence of arly age-related macular degeneration. Rarebit testing implies probing for gaps in the neuro-retinal receptive field matrix, using bright microdots on a dark background. Previous reports have found rarebit...

Persons with the CFH CC genotype have an increased likelihood of bilateral compared with unilateral age-related macular degeneration (AMD), according to a new study. AMD is an irreversible debilitating disease with complex genetic and environmental contributors. Recent research has focused on identifying the genetic predisposition to AMD, and...

A paper reports on two cases of fever following anti-VEGF injection. In the first case, a 76-year-old woman in good general health developed a fever (38.5-39.5° C) and chills 2-4 days following intravitreal injection of Avastin (bevacizumab) for age-related macular degeneration (AMD). The visual acuity was stable during the fever without...

Fish oil
Sep 17, 2009
Using data from the AREDS study, researchers find that consuming a diet rich in docosahexaenoic acid (DHA) - one of the active ingredients in fish oil - decreases the risk of progression of early age-related macular degeneration (AMD). Fish oil is rich in omega-3 long-chain polyunsaturated fatty acids (LCPUFA). Docosahexaenoic acid (DHA), the...

The skin is the largest organ of the body
Sep 14, 2009
A new study finds skin autoflourescence, a measure of overall metabolic stress, is greater in persons with age-related macular degeneration (AMD). Tissue advanced glycation end products (AGE) are a measure of cumulative metabolic stress. AGE accumulation within the body results from a combination of hyperglycemia, oxidative/carbonyl stress, and/...

Functional MRI
Aug 31, 2009
A new study investigating alterations in the cerebral neural networks associated with macular degeneration during performance of cognitively demanding tasks finds that the development and use of a preferred retinal locus (PRL) is associated with greater demands on cognitive resources. The authors believe that these increases reflect increased...

Diabetes
Jul 25, 2009
In the EUREYE study, a positive association between diabetes mellitus and neovascular age-related macular degeneration (AMD) was found. Other than age, the epidemiologic risk factors most consistently associated with AMD are cardiovascular risk factors. Many cardiovascular disease risk factors have been suggested as potential risk factors for...

Laboratory mouse
Jul 24, 2009
A new study involving mice finds that a diet with high levels of omega-3 fatty acids results in slower lesion progression, with improvement in some lesions. A diet high in omega-3 fatty acids has been found to protect against a variety of diseases including atherosclerosis and Alzheimer's disease. Retrospective studies have suggested that...

Diagram of a mitochondria
Jun 26, 2009
A new study finds that the mitochondrial (mt)DNA in the retinas of patients with age-related macular degeneration (AMD) contained more single-nucleotide polymorphisms (SNPs) within the control region of the geneome compared to normal retinas. There was an increased frequency of mtDNA SNPs associated with haplogroups J, T and U in patients with...

Vitreous
Jun 25, 2009
A new study finds that vitreomacular adhesion (VMA) is a risk factor for exudative age-related macular degeneration (AMD), and posterior vitreous detachment (PVD) may protect against exudative AMD. The cause of choroidal neovascularization (CNV) in exudative AMD is not fully understood, especially regarding the role of vitreous. Previous...
