NCSCs were delivered intravenously (5 million cells), retrobulbarly (0.5 million cells) or parabulbarly (0.5 million cells). Histomorphometric analysis of the retina was performed on stained haematoxylin-eosin sections with a thickness of 5 μm one month after the delivery of NCSCs.Results. NCSCs transplantation by all modes of delivery caused positive morphological changes to varying degrees. Intravenous administration induced a decrease in edema in all retinal layers and a slight restoration of the cytoarchitectonics of the retinal layers. The parabulbar administration of NCSCs led to a decrease in edema and the restoration of the cytoarchitectonics of the layers, most pronouncedly the ganglion cell layer and the inner retinal layer. After the retrobulbar administration of NCSCs, the reduction in edema and restoration of the cytoarchitectonics of the layers were the most pronounced.Conclusions. According to the results of the study, the positive effect of NCSCs transplantation in an experimental model of glaucoma was the most pronounced following the retrobulbar injection of cells. Further investigations of the mechanisms of the effect of transplanted NCSCs on retinal structure restoration are needed. ER -
