Retinal abnormalities in older people without diabetes are related to hypertension. Higher blood and pulse pressure are also associated with an increased incidence of macular abnormalities, including wet and dry age-related macular degeneration (AMD). These are the major findings of two studies appearing in the April issue of Ophthalmology, the clinical journal of the American Academy of Ophthalmology, the Eye M.D. Association.
The first study, assessing more than 2,000 men and women without diabetes, found retinal abnormalities in older people who do not have diabetes are related to high blood pressure, and retinopathy is associated with coronary heart disease, stroke, and carotid artery thickening. However, these conditions are distinct from atherosclerosis, a common form of hardening of the arteries.
According to Tien Yin Wong, FRCSE, MD, PhD, lead author of the Cardiovascular Health Study, "These changes may be markers for blood and small-vessel diseases of the brain, and have been shown to predict stroke independently of standard risk factors. Thus, patients with these changes may benefit from a full cardiovascular assessment." Dr. Wong is assistant professor at National University of Singapore and visiting assistant professor at University of Wisconsin-Madison.

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
