Type 2 diabetes increases the risk of glaucoma in women

13.07.2006
A 20-year study of women in the Nurses' Health Study has shown that Type 2 diabetes is associated with primary open angle glaucoma (POAG), the most common form of glaucoma, accounting for about 60 to 70% of all glaucomas. The study is published in the July issue of the journal Ophthalmology.

Researchers at the Massachusetts Eye and Ear Infirmary, Brigham and Women's Hospital, Harvard School of Public Health and Harvard Medical School observed 76,3128 women who were enrolled in the Nurses' Health Study from 1980 to 2000.

Eligible participants were at least 40 years old, did not have POAG at the beginning of the study, and reported receiving eye exams during follow-up. After controlling for age, race, hypertension, body mass index, physical activity, alcohol intake, smoking and family history of glaucoma, they found that type 2 diabetes was positively associated with POAG. However, the relation between type 2 diabetes and POAG did not increase with longer durations of type 2 diabetes.

"The study supports the notion that type 2 diabetes is associated with an increased risk of glaucoma," said Louis Pasquale, M.D., lead author of the study and co-director of the Glaucoma Service at the Massachusetts Eye and Ear Infirmary (MEEI) and an Assistant Professor of Ophthalmology at Harvard Medical School. "While obesity fuels the type 2 diabetes epidemic, it appears that factors unrelated to obesity contribute to the positive association between type 2 diabetes and glaucoma. We were surprised to find this. Our study had a large enough sample to allow us to focus on type 2 diabetes only and to study its relation to newly diagnosed POAG cases. We were also able to correct for other factors that could contribute to glaucoma. Our work suggests, but in now way proves, that factors other than lifestyle behavior contributing to insulin resistance could lead to elevated intraocular pressure and glaucoma."

According to the National Eye Institute, POAG affects more than 2 million individuals in the United States and is one of the leading causes of blindness. With the rapid aging of the U.S. population, the number of individuals affected by the disease will increase to more than 3 million by 2020.

The study suggests that people with type 2 diabetes should be screened for glaucoma. As of 2002, Medicare provides coverage for glaucoma screenings in beneficiaries with diabetes, helping to enhance access for this group who may be at risk for visual loss from POAG.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
