The study is the first investigation of glaucoma-therapy use in the U.S. to utilize longitudinal data from a nationally representative sample of Medicare patients. The researchers examined trends in glaucoma medication use and surgeries among adults aged 65 and older by analyzing data collected from 1992 through 2002 as part of the Medicare Current Beneficiary Survey (MCBS). A total of 3,020 MCBS participants were identified as having diagnosed POAG.
A major finding of this study is that, on average, 30 percent of Medicare beneficiaries with POAG did not use any glaucoma medication and did not undergo any type of glaucoma-related surgery in a given study year. Among those patients who did use glaucoma-related medications, the classes of prescription eye drops used changed over the study period, with a substantial increase in the use of prostaglandin analogues.
Lead researcher Joshua D. Stein, MD, MS, from Duke University in Durham, NC, said, "We’ve known that consistent use of effective medical therapies reduces patients’ risk for blindness due to glaucoma yet we found that many patients are not benefiting from the availability of these increasingly effective therapies. An important lesson emerges from this research: We need to do a better job of educating patients and their physicians, as well as health policymakers and insurance-industry leaders, of the benefits of consistent glaucoma therapy." He concludes, "If we do not learn this lesson, glaucoma will continue to be a leading cause of blindness in older populations."

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
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,...
