Can Viagra permanently damage vision?

Side effects can be even from the most innocuous pills, didn’t you know? But who would have thought that the beloved men “Viagra” can do harm instead of good.

What do you know about Viagra? The drug called sildenafil, it is “Viagra”, is used in the treatment of erectile dysfunction. In simple terms, it helps in problems with erection. Also, this drug can help in the treatment of gastroparesis and such a serious disease, as arterial hypertension. Not bad, if you do not take into account the fact that there may also be side effects, and quite serious ones.

Viagra: blindness instead of erection?

Science World Report recently revealed that researchers at the University of New South Wales have discovered that Sildenafil has a negative effect on human vision. The fact is that this drug hinders the normal functioning of the enzyme, which plays a decisive role in the transportation of light signals from the eye to the human brain. Particularly susceptible to people who have eye disease that can lead to blindness or with retinitis pigmentosa.

But also people with good eyesight are exposed to negative effects, because without knowing it, they can be carriers of the gene that causes retinitis pigmentosa. By the way, such a mutation can occur in 2% of the human population, that is, every 50th. Retinitis pigmentosa can develop due to mutations in the gene that produces the PDE6 enzyme. Patients who have two copies of an altered gene can get this disease. In simple terms, the man does not realize that he may have some problems with his eyesight, but if the entanglement of stars rewarded him with the wrong combination of genes, then taking Viagra, he can be awarded with visual illness.

The study conducted experiments on mice. Healthy and sick people were given a single dose of sildenafil for such a gene mutation. After it, even in healthy mice, there was a temporary loss of vision, not to mention mice with mutations. In the pupils of animals, scientists noticed signs of cell death. Thus, retinal disease carriers are affected by significant degeneration.

It is worth noting that before this study, scientists knew about temporary violations of the quality of vision in healthy people in the case of receiving high doses of their beloved Viagra. So, high sensitivity to bright light, as well as color disturbance, a kind of blurred vision is prescribed in such effects of this drug. Therefore, now scientists believe that the appointment of “Viagra” doctors should keep in mind that the consequences for the eye can be much more serious than temporary blurred vision. Another thing is that usually men take this drug without a prescription. So, it makes sense to think about the consequences of such “self-treatment”.
