Although not certified by the government, Avastin (also called Bevacizumab) is still used in treating eye diseases. Avastin 400mg finds application in treatment of some severe health issues, where other medications may fail.
In this post, we will discuss some details about using Avastin 400mg injection for eye diseases. Let’s have a look.
Many doctors utilize Avastin in the treatment of serious eye conditions, including retina like AMD. AMD is Age-related Macular Disease, which is one of the most common causes of blindness. In the U.S, it is found in people with 50 years and above of age. The condition is generally caused due to breakdown of the central part of your retina. The part is called Macula and is the most sensitive part of your eye. It works more like a film works in a camera. Any damage to the part causes trouble seeing.
Apart from AMD, Avastin is also used in the treatment of other eye ailments such as Diabetic Macular Edema and Central Retinal Vein Occlusion (CRVO). Macula helps in the detailed central vision of your eye. With it, you are able to see fine prints, drive your car, identify faces, and more.
Macular degeneration is of two types – dry and wet. In wet condition, your back of the eye is occupied with abnormal blood vessels. A few of these vessels may even leak blood or fluid. This leakage is the reason behind blur/distorted vision. If you do not treat it, you may lose your complete vision or the consequences can be severe.
What’s Off-Label Use of Avastin
Originally, Avastin wasn’t meant for eye diseases. After clinical trials and researches, it was found safe and effective to use. You can also buy Avastin from farmacia en linea ( Spanish phrase for online pharmacy). It has been approved as a chemotherapy drug by the U.S Food and Drug Administration (FDA).
The purpose is for treating metastatic colorectal cancer. The approval requires manufacturers to add a label of instructions, indications, risks associated, benefits, and other important info. As per the label, Avastin blocks VEGF – Vascular Endothelial Growth Factor. Blocking or slowing down VEGF results in preventing blood vessels from growing and causing further issue.
After a drug or device is approved by the FDA, doctors can use it under off-label for treating different issues. Avastin is used off-label by ophthalmologists for AMD and other eye conditions. After Avastin 400mg injection is given to patients as required, they tend to have less fluid and better maculas.
With improved state of retina, you can see better. It is also effective in treating Macular Edema in a few diabetic patients and some cases of CRVO. Avastin 400mg is injected in the white part of your eye through a needle. The syringe is so thin that you can barely see it. The doctor first cleans your eye to avoid any inflammation or infection and then numbs your eye for lessening pain.
In most cases, the pain of injection is just like a quick, burning sensation in your eye which is caused by the fluid used for cleaning your eye after injection.
