People suffering from Erectile Dysfunction have been very quick to embrace the Impotence drug called Viagra. Nobody can rule out the effectiveness of Viagra against Impotence but there are some cases where the drug is susceptible to some major side effects. These could be in the form a heart disease, diabetes and blindness.

New studies reveal the possible impact of Viagra on the visibility of a person. According to British Journal of Ophthalmology, a person may suddenly lose his eyesight resulting in Blindness. The doctors treating the problem, have warned their patients against the new fall out of Viagra.

Experts working on the subject feel that the drug could be reducing the flow of blood to the optic nerves resulting in the damage. Erectile Dysfunction drugs work on the mechanism of transferring more blood into the penis. The amount of blood being limited results in improper distribution of blood to other parts of the body. This may be one of the causes of blindness in people consuming the drug.

The manufacturers though, have criticized the new study saying the study is very brief and there is no clear indication of "Viagra” being solely responsible for Blindness.

Studies are still underway to find more and more cases, where people

have suffered from sudden blindness after consuming Viagra. The researchers continue to encourage men to have the consultation of a physician before going any further with Viagra.

FDA (Food and Drug Administration) has reported that the recent cases of blindness may have been due to diabetes and heart problems that people carried before consuming the drug. However, it has been known that the problem does affect people suffering from Erectile Dysfunction and the damage is more lethal in people consuming the blue bill.

The manufacturers of Erectile Dysfunction drug have different views regarding the whole issue. They say the results could vary depending on the patient's observational nature, his recalling capacity and the biasness of the interviewing person.
