Smoking And Drugs Increases The Risk Of Eye Diseases

Smoking And Drugs Increases The Risk Of Eye Diseases.
A in good house helps guard against cataracts, while certain medications raise the risks of this stereotypical cause of vision loss, two new studies suggest. And a third cram finds that smoking increases the risk of age-related macular degeneration, another disease that robs tribe of their sight. The first study found that women who eat foods that contain high levels of a variation of vitamins and minerals may be less likely to develop nuclear cataract, which is the most common type of age-related cataract in the United States.

The over is published in the June issue of the Archives of Ophthalmology. The researchers looked at 1808 women in Iowa, Oregon and Wisconsin who took area in a reflect on about age-related eye disease. Overall, 736 (41 percent) of the women had either nuclear cataracts apparent from lens photographs or reported having undergone cataract extraction.

So "Results from this analysis indicate that healthy diets, which reflect adherence to the US dietary guidelines - are more strongly reciprocal to the lower occurrence of nuclear cataracts than any other modifiable risk factor or protective financier studied in this sample of women," Julie A Mares, of the University of Wisconsin, Madison, and colleagues said in a news broadcast release from the journal. The second study found that medications that increase tender-heartedness to the sun - including antidepressants, diuretics, antibiotics and the pain reliever naproxen sodium (commonly sold over-the-counter as Aleve) - spread the risk of age-related cataract.

Researchers followed-up with 4,926 participants over a 15-year era and concluded that an interaction between sun-sensitizing medications and sunlight (ultraviolet-B) conversancy was associated with the development of cortical cataract. "The medications active ingredients act for a broad range of chemical compounds, and the specific mechanism for the interaction is unclear," Dr Barbara EK Klein and colleagues at the University of Wisconsin, Madison, said in the talk release. Their dispatch was released online in advance of publication in the August print issue of the Archives of Ophthalmology.

Laser Cataract Surgery More Accurate Than Manual

Laser Cataract Surgery More Accurate Than Manual.
Cataract surgery, already an bloody crypt and successful procedure, can be made more precise by combining a laser and three-dimensional imaging, a unusual study suggests. Researchers found that a femtosecond laser, used for many years in LASIK surgery, can shear into delicate eye tissue more cleanly and accurately than manual cataract surgery, which is performed more than 1,5 million times each year in the United States. In the ongoing procedure, which has a 98 percent good rate, surgeons use a micro-blade to cut a circle around the cornea before extracting the cataract with an ultrasound machine.

The laser plan uses optical coherence technology to customize each patient's comprehension measurements before slicing through the lens capsule and cataract, though ultrasound is still used to remove the cataract itself. "It takes some deftness and energy to break the lens with the ultrasound," explained outdo researcher Daniel Palanker, an associate professor of ophthalmology at Stanford University. "The laser helps to go like a bat out of hell this up and make it safer".

After practicing the laser procedure on pig eyes and donated hominid eyes, Palanker and his colleagues did further experiments to confirm that the high-powered, rapid-pulse laser would not cause retinal damage. Actual surgeries later performed on 50 patients between the ages of 55 and 80 showed that the laser draw circles in lens capsules 12 times more unyielding than those achieved by the conventional method. No adverse effects were reported.

The study, reported in the Nov 17, 2010 progeny of Science Translational Medicine, was funded by OpticaMedica Corp of Santa Clara, Calif, in which Palanker has an neutrality stake. The results are being reviewed by the US Food and Drug Administration, while the laser technology, which is being developed by several solitary companies, is expected to be released worldwide in 2011.

The Number Of Cataract Disease Increases As The Extension Of Human Life

The Number Of Cataract Disease Increases As The Extension Of Human Life.
Americans are living longer than ever before and most tribe who unexploded into their 70s and beyond will cultivate cataracts at some point. That's why it's important to know the risks and symptoms of cataract, what to do to postpone onset, and how to decide when it's time for surgery, experts at the American Academy of Ophthalmology (AAO) explained in a scoop release. People should get a baseline eye screening exam at age 40, when prematurely signs of disease and vision change may begin to occur, according to the AAO. During the visit, the ophthalmologist will simplify how often to schedule follow-up exams.

People of any age who have symptoms or are at risk for eye disease should serve as an appointment with an ophthalmologist to establish a care and follow-up plan. Risk factors for cataract involve family history, having diabetes, smoking, extensive exposure to sunlight, serious judgement injury or inflammation, and prolonged use of steroids, especially combined use of oral and inhaled steroids.
