Successful early stage research on reversing glaucoma & age related eye damage

Harvard Medical School scientists have successfully restored vision in mice by turning back the clock on aged eye cells in the retina to recapture youthful gene function.

They had success in reversing vision loss from glaucoma & from old age.

This has the possibility of clinical trials within 2 years. I think if those trials go well, we could have an exciting new tool for fighting blindness and maybe other age related problems within 10 years.

Diabetic retinopathy is caused by blood vessel damage in the back of the eye.
It doesn’t sound like this process would help but I’m not a qualified to say at all.
