Vascular Endothelial Growth Factor is a protein produced by the cells in your body. It helps in production of new blood vessels when the body requires it.
In conditions where the body produces too much of VGEF, abnormal blood vessels grow in your eye. These abnormal blood vessles damage your eye thus impair your vision.
Depending on your current eye condition and the diagnosis, your Ophthalmologist might suggest you a treatment that involves the use of one of these Anti-Vegf injections. You could be needing one injection or multiple such injections over a span of a few months depending on how your body reacts and responds to the same.
There is nothing to worry about having to take these injections! They are suggested keeping your eye health at the priority to ensure you the best possible vision.
