Japanese researchers use human stem cells to repair monkey's retinal hole, potentially improving macular hole treatments.

Japanese researchers have successfully used human stem cell transplants to repair a monkey's retinal hole, potentially improving treatments for macular holes that cause vision distortion. The study showed enhanced light response in the monkey post-procedure. While initial results are promising, including some mild transplant rejection managed with steroids, further research is needed to assess long-term safety and efficacy for human application.
