Lizard Tail Adaptations May Reflect Predators' Color Vision Capabilities

118225_web.jpg

Juveniles of numerous lizard species have a vividly blue-colored tail that likely serves to deflect predator attacks toward the detachable tail rather than the lizard's body. Now researchers have found that certain differences in blue and UV light reflectance in lizard tails are likely adaptations to predators with different color vision capabilities.

Eye Study Underscores the Long-Lasting Benefits of Controlling Diabetes

People with type 2 diabetes who intensively controlled their blood sugar level during the landmark ACCORD Trial Eye Study were found to have cut their risk of diabetic retinopathy in half in a follow-up analysis conducted four years after stopping intensive therapy. Investigators who led the ACCORD Follow-on Eye Study (ACCORDION) announced the results today in New Orleans at the American Diabetes Association annual meeting. The study was supported by the National Eye Institute.

New qPAINT Technology Gives Microscopes “Super-Vision”

Picture1.png

Knowing the exact number of molecules located at specific junctures in cells can be a critical measure of health as well as disease. For example, abnormally high numbers of growth factor receptors on cells can be an indication of cancerous and precancerous states. Now, a simplified method known as qPAINT uses the blinking pattern of the light that marks each molecule, to find, count, and study individual molecules that are just a few nanometers apart.

"Lazy Eye" Childhood Condition Can Be Treated in Adults

When Aleksandra Pryszczewska was a toddler, she often stumbled and bumped into things because of an eye condition called strabismus, or lazy eye. Her left eye veered to the far right, altering her line of vision causing her sight to be impaired. While strabismus is traditionally corrected during early childhood, Ms. Pryszczewska's only surgery was unsuccessful. Loyola is one of the few medical centers that treats adult strabismus.

Watch Your Step—Blur Affects Stepping Accuracy in Older Adults

Visual blurring—like that produced by bifocals or multifocal lenses—may cause errors in foot position when walking. And that could contribute to the risk of tripping and falling in older adults, suggests a study in the June issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.

Rare Eye Disease That Struck Oliver Sacks Gives Rise To Cancer Treatment Strategy

UUHC_140114_012.jpg

Eye cancer took the life of author and neurologist Oliver Sacks last year, bringing attention to the rare, hard-to-treat disease. Now, a team led by scientists at Huntsman Cancer Institute at the University of Utah report in Cancer Cell that a mutation that causes the cancer relies on a protein, ARF6, to distribute cancer-promoting signals. Further, treatment with a drug made against the protein inhibits eye tumors formation.

Infant Visual Reflex and Accuracy May Improve with Age

A recent study shows that infants and toddlers take longer to notice new visual stimuli and are less accurate in their gaze than adults, but slowly improve as they age. The findings reinforce the importance of raising young children in stimulating environments, and set an important baseline as detection of developmental disorders increasingly rely on tracking eye movements. The paper, “Development and learning of saccadic eye movements in 7-42 month-old children” was published in the Journal of Vision.

Visual Impairment, Blindness Cases in U.S. Expected to Double by 2050

The number of people with visual impairment or blindness in the United States is expected to double to more than 8 million by 2050, according to projections based on the most recent census data and from studies funded by the National Eye Institute, part of the National Institutes of Health. Another 16.4 million Americans are expected to have difficulty seeing due to correctable refractive errors that can be fixed with glasses, contacts or surgery.
