Scientists have discovered that Viagra,a blue pill commonly prescribed in the treatment of impotence,could be used to cure age related blindness.
A two-year trial conducted by scientists at the Columbia University in New York suggests that the anti -impotence drug could stop age -related macular degeneration in its tracks.
The researchers say that tests show the anti -impotence drug may stop further loss of vision for patients being robbed of their sight and could even repair damage that’ s already been done.
“ Recent research has found the condition is partly caused by reduced blood flow to the choroid , a vital layer of tissue that sits in front of the retina – and some small earlier studies had suggested Viagra can improve blood flow to this tissue , ” the research states.
In the Columbia study , five elderly patients with age -related macular degeneration were given two Viagra pills a day for two years. The results, published in the journal Ophthalmologica, revealed that the drug improved vision for one participant and completely halted deterioration for the others.
“ Some drugs can already slow progression of age -related macular degeneration and increase vision in some cases , but the medicines have to be injected into the back of the eye every month, ” the research states.
The researchers said : “ Viagra offers significant potential for vision retention and recovery . It is notable that patients remained visually stable and there was a significant improvement in vision in one participant. ”
