Adults who are elderly and eat fatty fish at least once a week may have a lower risk for experiencing serious loss of visibility due to a decrease of age-related macular, according to a study in the U.S..
Studies by several researchers at John Hopkins University in Baltimore did not prove that eating fish reduces the risk of esophageal phase of continued decline in age-related macular, or AMD.
But researchers Bonnielin K. Swenor said the findings add to evidence from previous studies that show people who eat fish tend to have a lower risk of AMD compared with people who do not often eat fish.
The study, reported in the journal Ophthalmology at the address (, also supports the theory that omega-3 fatty acids - most commonly found in oily fish such as salmon, mackerel and tuna, Albacore - may influence the development or progress of AMD.
"Although current research shows that foods rich in omega-3 fatty acids may reduce the risk of decline in age-related macular in some elderly patients, further studies remain necessary," said Swenor told Reuters Health.
For the study, Swenor and colleagues analyzed data from 2520 adults aged 65 to 84 years who underwent eye examinations and completed questionnaires about their diet in detail.
As many as 15 percent found to have an early or middle stage of AMD, while only less than 3 percent have advanced stage disease AMD.
That study participants who ate fish one or more times like that every week had 60 percent lower risk for having advanced AMD compared with those who rarely ate fish every week on average.
Overall, the researchers found no clear link between the participants who reported eating fish and the risk of AMD, but there was a correlation between the consumption of more fish rich in omega-3 and the possibility of advanced AMD.
AMD is caused by growth of abnormal blood vessels behind the retina or the outbreak of the cells that are sensitive to light - both of which can result in serious visual disturbances.
There is no cure for AMD, but a specific treatment may prevent or delay the serious loss of visibility.
One clinical trial found that the U.S. administration of high doses of a mixture of specific anti-oxidants - vitamin C and E, beta-caroten and zinc - could slow the progression of AMD who are at intermediate stages, and doctors can now jointly prescribe vitamin mixture for such patients.
Do fish or omega-3 intake can stop the development of AMD is unclear but the follow-up for U.S. trials of anti-oxidants are now studying whether to add fish oil and antioxidants lutein, zeaxanthin in supplements dna genuine additional benefits.
