Study Start Date: September 2011
Estimated Study Completion Date: January 2014
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.

Detailed Description:
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.

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • diagnosis of Ischemic Retinopathy
  • Enlargement of foveal avascular zone-FAZ (ischaemia or capillary drop out of >30% on Fluorescein retinography
  • logarithm of minimum angle of resolution (logMAR) BCVA of 1.0 (Snellen equivalent, 20/200) or worse
  • Able (in the Investigator's opinion) and willing to comply with all study requirements

Exclusion Criteria:

  • previous ocular surgery other than cataract
  • presence of cataract or other media opacity that would influence ocular fundus documentation and adequate ERG and visual field evaluation
  • other ophthalmic disease like glaucoma and uveitis
  • previous history of blood disorders like leukemia
  • known allergy to fluorescein or indocyanine green
