In the study, the researchers found when the objects' outlines had been enhanced, there was increased recognition. The device, called the Argus II, is the first FDA-approved retinal implant for adults with retinitis pigmentosa.

Eye injuries in NHL cost franchises more than $32 million Posted: 16 Nov 2013 02:11 PM PST Research shows that wearing visors in the National Hockey League (NHL) could cause a four-fold decrease in the risk of eye injuries. Furthermore, the study found that eye injuries over the last 10 seasons have cost the NHL and its associated franchises more than $32 million in missed games.

Residents of most polluted US Cities have increased risk of dry eye syndrome Posted: 16 Nov 2013 02:11 PM PST Residents of major cities with high levels of air pollution have an increased risk of dry eye syndrome, according to a study. Study subjects in and around Chicago and New York City were found to be three to four times more likely to be diagnosed with dry eye syndrome compared to less urban areas with relatively little air pollution.

Cardiac surgeon report cards do not influence referrals, study shows Posted: 15 Nov 2013 05:37 PM PST Despite nearly universal awareness of report cards on risk-adjusted mortality rates of individual cardiac surgeons, cardiologists in New York State do not use these reports when making patient referral decisions.

Large-scale analysis describes inappropriate lab testing throughout medicine Posted: 15 Nov 2013 05:36 PM PST A new study finds that, on average, 30 percent of all lab tests are probably unnecessary -- and equally as many necessary tests may be going unordered.

Mandatory calorie postings at fast-food chains do not influence food choice Posted: 15 Nov 2013 12:44 PM PST Posting the calorie content of menu items at major fast-food chains in Philadelphia, per federal law, does not change purchasing habits or decrease the number of calories that those customers consume, researchers have reported.

Study finds donor age not a factor in most corneal transplants Posted: 15 Nov 2013 12:44 PM PST Ten years after a transplant, a cornea from a 71-year-old donor is likely to remain as healthy as a cornea from a donor half that age, according to a study. Corneas from donors over age 71 perform slightly less well, but still remain healthy for the majority of transplant recipients after 10 years, the study found.

Safety in numbers? Not so for corals Posted: 15 Nov 2013 11:14 AM PST Traditionally, it was assumed that corals do not face a risk of extinction unless they become very rare or have a very restricted range. A team of scientists has revealed that global changes in climate and ocean chemistry affect corals whether scare or abundant, and often it is the dominant, abundant corals with wide distributions that are affected the most.

Inflammatory skin damage blocked by bleach solution in animal study Posted: 15 Nov 2013 10:02 AM PST Processes that age and damage skin are impeded by dilute bleach solution, according to a new study by researchers working with mice.

Promising approach to improve outcome for children with high-risk leukemia Posted: 15 Nov 2013 10:00 AM PST Results from a new study is showing that a drug withdrawn from the market in 2010 may enhance the effectiveness of bone marrow transplants for select pediatric leukemia patients.
