Consumer Warning: Halloween Eye Wear Accessory May Permanently Damage Eyes
Consumer Warning: Halloween Eye Wear Accessory May Permanently Damage Eyes
"With Halloween approaching, the American Optometric Association (AOA) is warning consumers about the risks of wearing decorative contact lenses without a prescription from an eye doctor. These non-corrective lenses, which are designed only to change the appearance of the eyes, are easily accessible to consumers and are especially popular around Halloween."

Age-related Macular Degeneration Linked To Low Antioxidant Levels And Sunlight Exposure
Age-related Macular Degeneration Linked To Low Antioxidant Levels And Sunlight Exposure
"Some types of the age-related macular degeneration (AMD) have been linked to low plasma levels of antioxidants and blue light exposure from the sun, according to researchers from Europe who published a paper in the October issue of Archives of Ophthalmology.
"The retina is vulnerable to the damaging effects of light," write author Astrid E. Fletcher, Ph.D. (London School of Hygiene & Tropical Medicine) and colleagues. "While wavelengths in the UV radiation range are largely absorbed by the cornea and lens, the retina is exposed to visible light, including blue light." According to previous animal and laboratory studies, it is possible that blue light can damage the retina and lead to a deterioration of the area of the retina responsible for sharp vision (the macula); this is called AMD...
...The researchers recommend that people consume key antioxidants by ingesting appropriate amounts of vitamin C, zinc, and carotenoid-rich fruits and vegetables. Further, they reiterate the standard precaution of wearing broad-rimmed hats and sunglasses to reduce the exposure of the retina to blue light."

Macular Degeneration Update
From: http://www.medicalnewstoday.com/articles/124992.php
Age-related macular degeneration (AMD) has been associated with a new gene, according to an article released on October 7, 2008 in The Lancet...
Dr Sarah Ennis and Professor Andrew Lotery, University of Southampton, UK, and colleagues examined a group of patients in the UK with AMD and a group of controls, screening 32 genes previously identified to be potentially involved in the chemical pathways related to AMD. The SERPING1 gene, a part of the so called 'complement' system in the eye that assists with clearance of foreign material and infection, was found in a higher proportion of the AMD patients than in the controls.
Subsequently, the study was repeated in a group of patients in the US, with similar results. Further, upon a high-density analysis, five additional variants of the SERPING1 gene were discovered to be associated with AMD.
"Our study shows a strong association between age-related macular degeneration and SERPING1, with supporting evidence from an independent replication and a secondary high-density scan of the gene...genetic variation in SERPING1 may implicate the classic pathway of complement activation in AMD...Our findings add to the growing
understanding of the genetics of age-related macular degeneration, which should ultimately lead to novel treatments for this common and devastating disease," the authors conclude.
