Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: test group intravitreal stem cell

Open-label study of Ischemic Retinopathy patients with best-corrected visual acuity (BCVA) worse than 20/200.

Intervention: Biological: intravitreal injection of autologous bone marrow stem cells
Biological: Intravitreal Bone Marrow Stem Cells
One intravitreal injection of a 0.1-ml cell suspension containing around 10x106 bone marrow mononuclear stem cells(BMMSC). All treatments were performed by a single retinal specialist using topical proparacaine drops under sterile conditions (eyelid speculum and povidone-iodine). Autologous BMMSC were injected into the vitreous cavity using a 27 gauge needle inserted through the inferotemporal pars plana 3.0 - 3.5 mm posterior to the limbus. After the injection, central retinal artery perfusion was confirmed with indirect ophthalmoscopy. Patients were instructed to instill one drop of 0.3% ciprofloxacin into the injected eye four times daily for 1 week after the procedure.
