Stem Cells to Treat Blindness

Stem Cells Blindness Eyesight Sight

For people who are blind, the thought of a treatment to restore their sight may seem like an impossible dream. But it may eventually become a reality after scientists last year were able to restore the eyesight of a blind person. The treatment works by replacing those cells in the eye know as retinal cells that have been damaged or worn out from diseases such as macular degeneration. For the elderly in particular, macular degeneration is a common concern as it can lead to enormous loss of vision in one or both eyes.

What is Macular Degeneration?

Macular degeneration is a top cause of vision loss in older adults. This is the most common illness that results in blindness in the elderly or for those people who lose their eyesight due to diabetes. It wrecks havoc on a person's central vision. This kind of vision is important for helping us to see objects clearly as well as helping us to perform basic, everyday tasks such as reading a book or driving a car.

When macular degeneration strikes, it affects the area of the eye that is important for allowing us to see fine details. The disease may progress very slowly so that a person barely notices any changes at all. Or, it might progress rapidly, causing significant vision loss.

Stem Cell Therapies

Those who might benefit the most from this stem cell treatment are people who suffer from macular degeneration. But researchers think it could work for other kinds of vision loss as well.

How it Works

To perform the stem cell transplant, researchers initially tested things out in blind mice. They injected stem cells into the rear of the eye. The stem cells were able to replace the damaged photoreceptors, which are small, important cells found in the retina. These photoreceptors are vital to your ability to see things and they are very sensitive to light.

Interestingly enough, previous studies using stem cells had failed to restore sight. One reason for the problem relates to the choice of stem cells. In the most recent study, researchers used stem cells that were more mature than the ones previous researchers had used. The choice proved successful as the stem cells developed into photoreceptors and were able to join with the nerves that lead to the brain.

Researchers hope to see these kinds of transplants happening on a greater scale in approximately ten years. With many patients suffering from diseases in the eye that cause photoreceptors to die, this research offers a way to provide photoreceptor transplantation, helping to restore eyesight for many people around the world. The use of a patient's own cells also avoids the potential for immunological rejection, a threat that comes with other types of treatment.

Cautiously Optimistic

Experts do still tend to warn that we should not assume this study means we automatically have a cure for blindness. It is just one case study and there are still a number of challenges and risks that come with the treatment. But it does offer hope for people who are blind from macular degeneration that they may one day have their eyesight again.

Can this treatment be used to treat (or even correct) damage caused by accidents or violence?I work in security and I was injured during my job which resulted in a torn, then partially detached retina.If this can help to restore sight to my blind spot and help with any future detachments I would be excited to hear about it further.

My son (26) and my daughter(22) both have Stargardts.They were both diagnosed with it at the ages of 9 and 10. Will stem cells help them.

Hello! My daughter (who is now 13) was born prematurely and suffers from ROP. She had a very aggressive form and it cause retinal detachment in both of her eyes. She is completely blind with no light perception. She had eye pain caused from the lack of growth in her eyes. She had bilateral eye enucleation performed a few years ago and now has prosthetics in place. Would she benefit from stem cell therapy?
Kaitlyn - 4-Feb-20 @ 4:32 PM
My daughter 6 months old she gets ROP stage 5 and have done the eyes surgery. However, this disease could not be cured. Could you let me know the stem cell therapy that could help her?

My father has been diagnosed with glaucoma and one eye has completely lost vision. He is 73.can he use stem cells to conserve vision of his remaining eye

I have marfans syndrome and have had multiple surgeries on both eyes. A few years back i had lasik done and it caused a retinal detachment. I was scheduled for surgery to fix this.Upon waiting for my surgery date i fell down a embankment and hit my head which so happened to knock the other retina loose.So when i arrived for surgery on my right eye, the doctor chose to do my left eye instead. By the time i got back for my right eye it was to late. So im looking for any kind off hope that is out there.I currently can not see anything out of the right eye and am noticing g gf
Chuck - 16-Dec-19 @ 3:06 PM
I had my retina detach two times in the past three years in my right eye. My vision is slightly distorted due to the detachments.I would be very interested in being a stem cell trial patient.I'm 38 years old and this affects every day of my life.Thanks for taking the time to read this.
JUSTIN - 8-Dec-19 @ 2:33 AM
Please help I have a Left detached retina and went blind in 2004. Can stem cell therapy help me to see again . I am 62 yrs old. Is there any research I can get on a list. Since macular degeneration and glaucoma run in my family so I don’t want to lose my right eye as well.
Susan - 17-Nov-19 @ 6:13 AM
I was diagnosed with premature retinas and wondering if stem cells could regenerate what was supposed to fully developed at birth? I’m thinking the layout of development was set from birth but maybe something interrupted the process. Would stem cells jumpstart the process to finish what was interrupted? Thank you
Gabe - 28-Oct-19 @ 5:24 PM
What doctors currently are reporting some success in the use of stem cells to repair and impart vision to blind and partially blind individuals.Are these NIH samctioned trials in this country or are these trials taking place in other countries like China?Who seems to be having the most successes?

9 yasinda oglum retina dekolmani oldu bir kez ameliyat gecirdi isik hissi hareket var buyuk nesneler var ama ayrinti yok diyor kok hucre tedavisi onerildi yapilabilecek bir sey varmi
Esbi - 18-Jun-19 @ 4:50 PM
Misdiagnosed Glaucoma in my left eye was declared a TIA. If they had simply tested the pressure in that eye it would have been easily treated now 98% of vision in my left eye is gone. There is a tiny window of clarity in the dead center of left eye. I’m willing to risk everything to have a shot at vision in my left eye again.
Naterman - 6-May-19 @ 9:24 AM
