application avastina in ophthalmology reviews

In the US, there was a serious scandal over the use of Avastin for the therapy of macular degeneration. Injection of the drug into the vitreous body led to the emergence of a full set of side effects. At the same time, 16 patients had serious infections in the eyeball. Some people developed absolute blindness. But Avastin continues to be used both in the US and in Europe. Such a wide application of the drug is not due to indications, it is not due to illegal promotion, but to the cheapness of the drug in comparison with the legal "Lutsentis", approved for the treatment of retinal dystrophy.

The difference in the price of these drugs is significant. While in the US the price for Avastin is $ 50, the price of Lucentis is $ 2,000.Note that in terms of the occurrence of complications and side effects, as well as the development of endophthalmitis, "Lucentis" is not ideal. That is why many people risk and buy an unofficial Avastin.

According to many doctors, it's all about the technique of introducing funds. It is necessary to carry out research in this area. Some of them have already been made. Thus, a comparison was made between the effects of bevacizumab and ranibizumab( active substances of Avastin and Lucentis, respectively).There have been two studies, but their results have been controversial, because in the first, bevacizumab proved to be safer, and in the second, ranibizumab.

injections avastina in the eye reviews

For today in Russia the preparation is forbidden for application in ophthalmology. But still you can find a seller and a doctor who will make an injection.

For a few injections of the drug, the eye swelling subsided, and visual acuity improvement was observed. Therapy gives a positive effect not immediately, but after the side effects occur. In addition, expect a visible positive effect after the first injection of the drug is completely meaningless.
