Oily fish may protect eyesight
Consuming oily fish once a week or more may help to protect eye sight in later life, it has been suggested. ... Continue Reading
UV causes long-term eye damage
Cumulative exposure to the sun's UV rays can lead to permanent loss of vision, experts warn. ... Continue Reading
Researchers develop groundbreaking diagnostic test
A new licensing agreement has brought anti-aging physicians one step closer to being able to assess a patient's risk of age-related blindness before symptoms manifest. ... Continue Reading
Scientists discover mechanisms of senile blindness
Hyperactive immune resistance has been associated with senile blindness caused by age-dependent macular degeneration (AMD). ... Continue Reading
Workplace noise 'leads to permanent hearing damage'
Prolonged exposure to noise in the workplace could lead to tinnitus and longer-term degeneration of hearing, studies have shown. ... Continue Reading
Trials for 'bionic' eye implants
A bionic eye implant that could help restore the sight of millions of blind people could be available to patients within two years. US researchers have been given the go-ahead to implant the prototype device in 50 to 75 patients. The Argus II system uses a spectacle-mounted camera to feed visual information to electrodes in the eye. ... Continue Reading
Children born preterm need follow-up eye tests
A new study confirms that children born prematurely (before 35 weeks gestation) run a higher risk of developing vision problems than children born at term. This is true regardless of the degree to which blood vessels in the retina have developed abnormally because of preterm birth -- a condition known as "retinopathy of prematurity." The new study, reported in the Archives of Ophthalmology, also suggests that eye tests performed at 2.5 years of age in preterm children can predict vision problems at age 10 -- namely, astigmatism, which is an unequal curve in of the eye's refractive surfaces, and anisometropia, a difference in refractive power between the two eyes that can lead to partial vision loss. ...

Vax And Pax: Taking Turns To Build An Eye
Opposing ball clubs don't take the field at the same time, and neither do teams of proteins responsible for creating the eye. While one team builds the retina, in adjacent cellular turf the opponents are busy constructing the cord that carries visual signals to the brain. And these guys aren't supposed to mingle. ...

More Than Meets The Eye
Ever watch a jittery video made with a hand-held camera that made you almost ill? With our eyes constantly darting back and forth and our body hardly ever holding still, that is exactly what our brain is faced with. Yet despite the shaky video stream, we usually perceive our environment as perfectly stable. ... Continue Reading
Researchers Identify Dart-like Molecule In Age-related Macular Degeneration
A dart-like molecule that adheres to proteins in the eye is the key that turns on the uncontrolled growth of blood vessels, according to researchers at Case Western Reserve University and the Cleveland Clinic Cole Eye Institute. Uncontrolled blood vessel growth is a major contributor to the development of age-related macular degeneration (AMD), the leading cause of blindness among people over 65 in the United States. ...
