Blindness

Blindness is loss or absence of the ability to perceive visual images. The condition of a person having less than 1/10 (20/200 on the Snellen test) normal vision. Blindness may be caused by injury, by lesions of the brain or optic nerve, by disease of the cornea or retina, by pathological changes originating in systemic disorders (e.g., diabetes) and by cataract, glaucoma, or retinal detachment. Blindness caused by infectious diseases, such as trachoma, and by dietary deficiencies is common in underdeveloped countries where medical care is inadequate.

Controlling inflammation in macular degeneration prevents progress of AMD
Scientists at Trinity College Dublin have discovered that a part of the immune system called the inflammasome is involved in regulating the development of one of the most common forms of blindness, called Age-Related Macular Degeneration (AMD).

Eylea approved for AMD eye disorder in older people
The U.S. Food and Drug Administration approved Eylea (aflibercept) to treat patients with wet (neovascular) age-related macular degeneration (AMD), a leading cause of vision loss and blindness in Americans ages 60 and older.

Vitamin A supplements can save children
Researchers have strongly recommended vitamin A supplementation for children under 5 in areas at risk of vitamin A deficiency. Children in low and middle income countries should be given vitamin A supplements to prevent death and illness, concludes a study published on bmj.com today.

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, revealed by researchers.

Women can be blinded by jealousy, unpleasant emotions
Women who were made to feel jealous were so distracted by unpleasant emotional images they became unable to spot targets they were trying to find, revealed by two University of Delaware psychology professors.

Smoking increases AMD risk even after age 80
Smoking, even after age 80, continues to increase one's risk for age-related macular degeneration (AMD), the leading cause of blindness in Americans over 65.

Stem cells may recover lost vision in cloudy cornea
New research from the University of Cincinnati (UC) may help in the recovery of lost vision for patients with corneal scarring.

Cataract surgery does not progress AMD
Age related macular degeneration does not appear to progress at a higher rate among individuals who have had surgery to treat cataract, revealed by researchers.

Gene therapy may improve vision in congenital blindness LCA
Researchers from the University of Pennsylvania School of Medicine and the Center for Cellular and Molecular Therapeutics at the Children's Hospital of Philadelphia have used gene therapy to safely improve vision in five children and seven adults with a rare form of congenital blindness.

Diabetes may weaken your bones
The inflammatory molecule TNF-a may contribute to delayed bone fracture healing in diabetics, revealed by researchers. Diabetes, a condition where the body either does not produce enough, or respond to, insulin, affects at least 171 million people worldwide, a figure that is likely to double by 2030.

Study reveals how brain learns to see
By testing formerly blind patients within weeks of sight restoration, Sinha and his colleagues found that subjects had very limited ability to distinguish an object from its background, identify overlapping objects, or even piece together the different parts of an object.

Improve contact lens safety, says US FDA
The U.S. Food and Drug Administration is taking steps to improve contact lens safety by reminding consumers of the importance of following proper cleaning and storing procedures.

Antioxidant supplement CARMA improves vision in AMD
The antioxidant nutritional supplement may help those affected by the leading cause of blindness in the Western World, a five-year research programme has found.

Saffron has remarkable effects on eye vision
The herb saffron may hold one of the keys to preventing the loss of sight in old age – and may even help to improve vision in people suffering certain blinding eye diseases.

Health care providers can expect a significant increase in age-related macular degeneration as the baby boom generation reaches retirement age, according to a new study by researchers at RTI International and the Centers for Disease Control and Prevention.

Eat oily fish to protect your eyesight in old age
Eating oily fish once a week may reduce age-related macular degeneration (AMD) which is the major cause of blindness and poor vision in adults in western countries and the third cause of global blindness, according to a study published in the American Journal of Clinical Nutrition.

Protein Robo4 may reverse macular degeneration, diabetic retinopathy
Two major eye diseases and leading causes of blindness-age-related macular degeneration and diabetic retinopathy-can be reversed or even prevented by drugs that activate a protein found in blood vessel cells, researchers at the University of Utah School of Medicine and several other institutions have announced in a new study.

Genes involved in inflammation may hold clue to age-related macular degeneration
A University of Southampton research team, led by Professor Andrew Lotery, has identified a new genetic risk factor for age-related macular degeneration (AMD), a major cause of untreatable blindness in elderly people in developed countries.

$2 million of potentially harmful cosmetic eye product seized in US
At the request of the U.S. Food and Drug Administration, U.S. Marshals seized 12,682 applicator tubes of Age Intervention Eyelash, a product that may, in some users, lead to decreased vision. Authorities said the sales value of the seized tubes is approximately $2 million.
