"About 95 percent of patients regain their sight after treatment, and in some, vision gradually gets better than it was before the onset of the disease."
Sigh....another hopelessly sensationalistic headline.
A promising drug, BUT it must be understood that the "95 percent of patients who regain their sight" are from a very narrow group, selected for their chance to succeed. Throwing this drug at every patient with exudative maculopathy (wet AMD), would result in a much lower success rate.
Like any treatment, this drug's success hinges largely on the stage of the disease, the exact mechanism of tissue destruction and accompanying conditions.
