Treat Macular Degeneration By Injecting Stem Cells

Researches show that macular degeneration is one of the main causes for blindness among aging people

. As for how to treat macular degeneration, researchers and opticians has done a lot of researches and studies. Through their hard work, they have made some improvements in this field. The following will give some introduction on macular degeneration, its treatment, more important, a new and promising way to treat it by injecting stem cells.

There are two types of macular degeneration, one is dry macular degeneration, and the other is wet macular degeneration. 90% people with macular degeneration are diagnosed of dry macular degeneration, which leads to 10% blindness. While 10% macular degeneration is wet macular degeneration, which is responsible for 90% blindness. Though dry macular degeneration is not as serious as wet macular degeneration, but if not taken good card of, it can turn into wet macular degeneration.

Dry macular degeneration is caused by drusen forming on the eye. People with this kind of eye disease can choose dietary supplements to slow down the possible deterioration from dry AMD to wet AMD, but there are no other treatments. The abnormal blood vessel growth and leakage is the reason for wet macular degeneration. The common treatment for wet AMD is to inject anti-VEGF drugs into eyes, such as Avastin nod Lucentis which can prevent abnormal blood vessel growth and leakage.

Researches for better treatments of macular degeneration have never been stopped as there is increasing number of this eye disease worldwide. With the joining of some pharmaceutical companies and by their hardwork, they have indeed made some improvements in this line. Nowadays, the stem cell treatment is considered to be the most promising to treat this eye disease.

The stem cell treatment is raised by researchers from the University of Washington. The main principle is to use humans stem cells to regenerate their damaged retinal cells. As we may know, macular degeneration makes some damages to the retina and the retina can not repair themselves. Researches find they can use peoples embryonic stem cells and proteins to make cell growth, and then make these growing cells to become progenitor cells for retinal cells. Therefore, we can inject these cells to the damaged retina, and they can grow into cones, and also rods, and at last into other retina cells.

Nowadays, scientists have made a lot of researches on injecting stem cells to treat macular degeneration. Now they are seeking the way to measure the nerve reactions to see if the vision is improved. Anyway, they consider it is a promising treatment for macular degeneration and it is believed that people with macular degeneration will benefit a lot from stem cell treatment in the near future.
