Scientists have reported that stem cells can cure blindness in humans. These cells are used by grafting into the damaged eye vessels. The healthy cells then start working to repair the damaged cells and thus treat blindness in humans. Glaucoma is known as the silent thief of sight can hope for treatment but still studies need to be done to ensure the efficacy. Current treatments just slow the damaging progress of the disease but Glaucoma patients can hope for stem cell treatment as a boon. The stem cells can hopefully provide a cure to the patients who are suffering from blindness. The therapy has seen good results in animal models against glaucoma damage. To improve vision in patients with glaucoma, stem cell treatments are now ready for human trials. The therapy needs more consideration and studies to ensure the cure of blindness.
