Viagra Could Be The Answer To Blindness

Posted in : News on by : Dr Richard Petty

For the last two years, scientists from Columbia University (New York) have been carrying out a trial program to study the long-term effects of the popular anti-impotence drug Viagra. However, the findings held more questions than they had hoped to answer. It turns out that the little blue pills could be the cure for age-related macular degeneration (AMD).

AMD is known to be the leading cause of adult blindness with an estimated 2.1%of all American adults suffering from the same. Out of these, 90% had dry AMD which usually kicks in slowly as one ages. Dry AMD occurs when new blood vessels grow over the macula which is an oval-shaped region at the back of the eyes. This region is responsible for picking out visual details. The blood vessels lead to scar formation which destroys the macula’s ability to recognize visual information.

Reduced blood flow to the choroid contributes towards intensification of AMD. This is where Viagra comes in; the drug has the ability to improve blood flow into this tissue. For the last two years, the Columbia team studied five elderly patients and administered 2 Viagra pills each day for a period of two years.

The results which have been published in the Ophthalmological Journal, paint a rather bright future for AMD patients. According to the led researcher, Viagra offers significant abilities for vision retention and recovery. In one participant they observed substantial visual improvement while others remained relatively healthy.

Professor Sobha S. from the Royall Ophthalmologists College says the findings are more than just encouraging and could actually pave the way to using Viagra as a treatment remedy for AMD. Although more data is needed before any of that starts.

Previous studies conducted by various institutes have shown that the little blue pills could be used to treat other ailments such as lung diseases, dementia, and even heart attacks.

Currently, Viagra is one of the most sought-after drugs due to its ‘miraculous’ effects on male impotence. If the study is approved for a second round, then the institute will engage a larger crowd so as to get more conclusive results and hopefully what might come to be a happy ending for AMD patients.

Currently, AMD has no cure. Patients are instead given a combination of vitamins and minerals to support vision, but this doesn’t always work. The combination is injected into the eye a process that is rather gruesome and painful for the patients. For now, we have to wait and see if the findings will hold up to the test of time.
