Cataract surgery improved vision in patients with any stage – from mild to advanced – AMD in the first study to include a sufficient number of patients with AMD. Data were obtained from the multicenter, prospective, age-related Eye Disease Study , funded by the National Eye Institute , which was organized primarily to assess the effects of high doses of vitamin and mineral supplements on cataract and AMD . Like the United States population ages the prevalence AMD is expected to increase, and many patients will develop cataracts at the same time, both diseases can lead to blindness if left untreated.This month, Ophthalmology, the journal of the American Academy of Ophthalmology reports a national study found that surgery can benefit patients with AMD at all stages of the disease, a clinical trial showing that the steroid triamcinolone may be Diabetic macular effective in advanced patients when standard treatment fails and the use of two public forums sponsored Academy online eye health.
A five-year study based at the University of Sydney, Australia, found that intravitreal triamcinolone actually improved vision in patients with DME, a form of, whose eyes had continued to deteriorate despite standard laser treatment.

In the first three months after treatment, patients initially treated with two ivta and laser showed significantly better gains in the vision that the control patients who were treated with laser alone. After two years, the original control patients were treated with ivta. In addition, two thirds of all patients were operated for cataract during the study period. Similar results were observed in other studies of treatment with steroids and, therefore, were not considered as new security challenges by the group of Dr. Gillies.
The majority of patients who improved after initial treatment with ivta continued to live the best vision at the end of five years of our clinical trials, and no new safety concerns were found in these patients, said researcher Main, Mark Gillies, PhD. We believe that treatment with ivta can be considered in carefully selected patients when the DME advanced standard treatment failed to improve vision, he added.
On average, patients with AMD, ranging from mild to advanced experience visual acuity after cataract surgery, the best gains were in patients with vision worse than before surgery than20/40. No difference in improvement was observed among patients with wet or dry of AMD. About a year later, the vision has remained statistically significant increases in the 865 eyes available for follow-up. Results for the primary purpose of the study on the effects of the AREDS nutritional supplements, found that high doses of vitamins C, E and beta-carotene has no impact on the development or progression of cataracts, but the combination of vitamin more zinc reduced the risk of progression to advanced AMD by 25 % within five years of the study.
But it is unclear which messages have been taking risks on the various social or cultural groups, and little is known about the emergence of new risk factors or previously unrecognized.
