A new study has shown that people who regularly eat oranges are less likely to develop macular degeneration than people who do not eat oranges. Researchers at the Westmead Institute for Medical Research interviewed more than 2,000 Australian adults aged over 50 and followed them over a 15-year period.
Traditional Medicare doesn't cover eyeglasses except after cataract surgery and changing the policy has been discussed. Recent estimates of eyeglass use by Medicare beneficiaries could shed light on the implications of any policy change. A new study estimates 92 percent of Medicare beneficiaries 65 or older (an estimated 40.5 million people) reported using eyeglasses for distance or near vision correction in 2015, a frequency of eyeglass use that has remained stable.
A multi-hospital collaboration led by researchers at Children's Hospital of Philadelphia (CHOP) has found a simple method of determining which premature infants should be screened for retinopathy of prematurity (ROP).
HIV-positive children in South Africa are more likely to have developmental disabilities compared to children who are HIV negative. HIV-positive children ages 4 to 6 had nearly four times the odds of delays in sitting, standing, walking, and speaking, and more than twice the odds of a hearing disability and cognitive delay compared to HIV-negative children.
Researchers have shed new light on the psychiatric and neurological problems that Ebola survivors can suffer from, and call for more specialist support for the most severely affected patients.
Nearsightedness (myopia) is a leading cause of visual impairment worldwide. A new study of about 4,700 Chinese schoolchildren suggests the rate of nearsightedness may be 20 percent to 30 percent each year from first grade onward. If such a frequency is confirmed with further testing, researchers suggest interventions to reduce the onset of nearsightedness, such as increasing the time spent outdoors, should be initiated in primary schools.
An analysis of recent high-quality research reveals that diet may affect individuals' risks related to the development and progression of age-related macular degeneration (AMD). The findings are published in Clinical & Experimental Ophthalmology.
The posterior parietal cortex plays a crucial role in allowing the mammalian brain to turn visual information (such as a green traffic light), into motion (such as stepping on the gas), researchers at MIT's Picower Institute found in a new study.
Cataract surgery was associated with a modest decrease in the risk of being involved in a serious traffic crash.
Worsening vision and declining cognitive function are common conditions among older people. Understanding the association between them could help reduce age-related cognitive changes. A study of more than 2,500 adults aged 65 and older found rate of worsening vision was associated with rate of declining cognitive function.
