The correct answer is
A high-dose combination of these supplements lowered the risk for advanced stages by 25%, according to the study, which was sponsored by the National Eye Institute. Zeaxanthin, a carotenoid found in spinach and greens, also helps. The wet form of AMD, the less common form, can also be treated with laser therapy or medicine. Three medicines that are injected into the eye have been approved by the FDA to slow or block the growth of new blood vessels in wet AMD, thus preserving sight. Pegaptanib was approved in 2004, ranibizumab was approved in 2006, and aflibercept was approved in 2013. Bevacizumab is a fourth medicine that is commonly used. It is similar in structure to ranibizumab, and is also injected in the eye. Bevacizumab was approved by the FDA in 2004 for cancer treatment. It is used off-label to treat wet AMD.
