Currently there are no treatments for Advanced Dry AMD, also known as GA, which can lead to significant central vision loss.
The National Eye Institute (NEI), one of the federally funded National Institutes of Health, is launching the first clinical trial in the US for induced pluripotent stem cells (iPSC), stem cells that are derived from mature human cells. The iPSC in the landmark study are being derived from the patients own blood and developed into retinal pigment epithelial (RPE) cells for the treatment of geographic atrophy (GA), the advanced form of dry age-related macular degeneration (AMD), which causes progressive central vision loss.
The 12-person, Phase 1/2a, safety trial will be conducted at the NEI in Bethesda, Maryland.
The hallmark of GA is the loss of RPE cells, a single layer of cells which provide essential nutrients and waste disposal for photoreceptors, the cells that make vision possible. When RPE cells degenerate or dont function properly, photoreceptors in the macula, the center of the retina, are lost.
By replacing a patients lost or dysfunctional RPE cells, researchers hope to save and possibly restore their photoreceptors, and therefore, their vision.
By using a patients own iPSC to produce RPE cells rather than RPE cells derived from embryonic stem cells the researchers believe they will minimize the chance of cell rejection.
The sheet of RPE cells for the emerging treatment are grown on a biodegradable scaffold to promote their integration when surgically placed between the patients own RPE cells and photoreceptors.

As we have an aging (including myself) group here who have or may start to run into these kinds of troubles, I am glad these threads are posted to keep folks in the loop.
My lasik surgery of 17 years ago is not standing the test of time in the left eye.
I am sure it was never meant to as eyes do what they do, lose focus or deteriorate over time, even after surgery
This is wonderful news. Thank you for the thread.
I pray for this cure. My father had laser eye surgery a few years ago. Seemed good for almost a year. Within a year he list most of his sight. They said it was AMD. But as fast as it happened and right after lasik, we can’t help but wonder if related.
I have been hoping and praying for his eyesight.
I didn’t put up the thread but I WILL pray for your pop.
Thank you. Very appreciated.
thanks for this. I have dry AMD. It has been “holding”. for about three years, but this gives me hope—maybe too late for me but not for others. I will go to the link.
