People with a rare inherited disease resulting in severe swelling of soft tissues, particularly around the eyes, lips, nose, and tongue, that in the most severe cases can lead sufferers to choke to death, could soon be treated with new and more effective treatments, according to Cardiff University's Dean of Medicine.

The apparent ability of long-lived parrots to see ultraviolet light without sustaining eye damage could provide new insights into UV protection in humans.

In high-risk adults with type 2 diabetes, researchers have found that two therapies may slow the progression of diabetic retinopathy, an eye disease that is the leading cause of vision loss in working-age Americans. 

A quick, painless eye measurement shows promise as a way to diagnose multiple sclerosis in its very early stages, and to track the effectiveness of treatments, researchers from University of Texas Southwestern Medical Center have found in a multicentre study.

A gentle oxygen-delivery technique is as effective as a more invasive one for treating very preterm infants, according to a new study. The researchers also found that slightly lower oxygen levels decrease the risk for eye damage but may raise the risk of death.

Surgeons at Johns Hopkins have safely and effectively operated inside the brains of a dozen patients by making a small entry incision through the natural creases of an eyelid to reach the skull and deep brain. 

Women who eat foods rich in a variety of vitamins and minerals may have a lower risk of developing the most common type of cataract that occurs in the United States, according to a report in the June issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

Parkinson's disease, the second most common neurodegenerative disease after Alzheimer's, is often treated with amantadine. The drug helps alleviate patients' motor problems and may be taken for years. Doctors have long known that amantadine treatment causes abnormal changes in the cornea in some Parkinson's patients.

Seniors who take SSRI antidepressants may be more likely to develop cataracts, says the first major study to examine this interaction. The risk appears to increase by about 15 percent, which in the United States would translate to 22,000 cataract cases attributable to antidepressant use.

Two findings from an National Institutes of Health research network study provide new information on how much oxygen very preterm infants should receive starting on the first day of life and the most effective means to deliver it to them.
