Used football faceshields are susceptible to breaking on impact

Used football faceshields are susceptible to breaking on impact

ScienceDaily (May 23, 2011) — Game-worn football faceshields are more susceptible to breaking when subjected to high-velocity impact than are new faceshields, according to recent research. In the study, researchers used an air cannon to hurl baseballs at new and used polycarbonate faceshields Continue reading

Single bioptic telescope for low vision driving may not obscure road view of second eye

Single bioptic telescope for low vision driving may not obscure road view of second eye

ScienceDaily (May 9, 2011) — A study by scientists at Schepens Eye Research Institute shows that a bioptic telescope on one lens of a pair of glasses used to magnify traffic signs and lights may not prevent the wider view of the road with the second eye. The study results, which will be published in the May 2011 Archives of Ophthalmology, are the first evidence that–under more realistic viewing conditions than in earlier studies–the second eye can detect objects in the area obscured by the magnification effect of the telescope (called the ring scotoma). “These study results are significant because they should ease official and public concerns about the safety of bioptic telescope use for driving with visual impairments,” says Dr. Continue reading

Study evaluates cost-effectiveness of strategies to treat infant tear-duct obstruction

Study evaluates cost-effectiveness of strategies to treat infant tear-duct obstruction

ScienceDaily (May 9, 2011) — When infants’ tear ducts are blocked, the decision about when to intervene and the cost-effectiveness of doing so depend on how likely it is the problem will self-resolve, according to a report in the May issue of Archives of Ophthalmology , one of the JAMA/Archives journals. It is not uncommon for babies to be born with blockage of the tear ducts, a condition known as congenital nasolacrimal duct obstruction (NLDO). In many cases, the condition will resolve spontaneously by the time a child is one year old Continue reading

Gene therapy shows promise against age-related macular degeneration

ScienceDaily (Apr. 29, 2011) — A gene therapy approach using a protein called CD59, or protectin, shows promise in slowing the signs of age-related macular degeneration (AMD), according to a new in vivo study by researchers at Tufts University School of Medicine. Continue reading

Bioengineering students’ invention may help diagnose painful eye condition

Bioengineering students’ invention may help diagnose painful eye condition

ScienceDaily (Apr. 25, 2011) — Rice University bioengineering students responded to an ophthalmologist’s cry for help with a device to diagnose dry eye, the itching and burning sensation that results when a person doesn’t produce enough tears or the tears evaporate too quickly. A team of five seniors made a portable unit that controls the air around a patient’s eyes so doctors can study and treat those who suffer from this painful condition Continue reading
