摘要:
AIM:To evaluate the role of bone marrow-derived stem cells in the treatment of advanced dry age-related macular degeneration(AMD) using multifocal electroretinogram(mf-ERG) and fundus autofluorescence imaging.METHODS:Thirty patients(60 eyes) with bilateral central geographic atrophy(GA) were recruited.Worse eye of each patient received autologous bone marrow-derived hematopoietic stem cells(BM-HSCs)(group 1) and the fellow eye with better visual acuity served as control(group 2).The effect of stem cell therapy was determined in terms of visual acuity,amplitude and implicit time in mf-ERG and size of GA on fundus autofluorescence imaging.These tests were performed at presentation and first,third and sixth month follow up.Adverse events(if any) were also monitored.RESULTS:At 6 mo follow-up there was no statistically significant improvement in median log MAR best corrected visual acuity(BCVA) in either group.Mf-ERG revealed significant improvement in amplitude and implicit time in the intervention group.A significant decrease was also noted in greatest linear dimension(GLD) of GA in the eyes receiving stem cells [6.78±2.60 mm at baseline to 6.56±2.59 mm at 6 mo(P=0.021)].However,no such improvement was noted in the control group.CONCLUSION:Electrophysiological and anatomical improvement in the intervention group sheds light on the therapeutic role of BM-HSCs.Further studies are required to determine the stage of disease at which the maximal benefit can be achieved and to standardize the dose and frequency of stem cell injection.
