This study aims to evaluate the behavior of the intravitreal use of bone marrow derived stem cells in patients with ischemic retinopathy.
Evaluate the effects on visual acuity, electroretinography, fluorescein angiography and optical coherence tomography in 30 patients with ischemic retinopathy, including diabetic retinopathy with severe loss of retinal capillaries undergoing intravitreal injection of bone marrow derived 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.
