Autologous stem cells from bone marrow, adipose, peripheral blood or allogenic cells from amnion, cord blood, wj, plasma proteins have an unlimited ability to proliferate under the right conditions and can also give rise to almost any cell type. Therapeutic stem cell targets in Glaucoma aims at enhancing the functional recovery of existing retinal ganglion cells and/or protecting the existing cells from further damage. Numerous animal studies have clearly established the neuro-protective effect of stem cells in restoring vision in glaucoma animal models. The eye being an immune privileged site, administration of stem cells is not usually associated with adverse events. The extent of vision recovery however can however vary from patient to patient depending on the severity of the disease and its stage. Administered stem cells usually exhibit beneficial effects by slowing down the degeneration of existing ganglion cells and also by conferring a neuro- modulatory and neuro-protective role. Existing stem cells present in various parts of the human eye are also kick started into action. Benefits observed by the patient are usually due to a combination of the various aforementioned effects. A reduction in IOP and vision improvements are perceived by the patient over a period of time.
