Suprachoroidal Umbilical Cord-Derived Mesenchymal Stem Cell Transplantation for the Regeneration of Glaucomatous Optic Neuropathy: A Preliminary Investigation
Journal Title: Journal of Regenerative Medicine & Biology Research - Year 2024, Vol 5, Issue 3
Abstract
Objective: This preliminary research presents clinical findings from patients with advanced Glaucomatous Optic Neuropathy (GON) who underwent transplantation of Umbilical Cord-Derived Mesenchymal Stem Cells (UCMSCs) into the suprachoroidal space. Methods: This prospective, single-center study included 17 eyes of 17 patients diagnosed with GON, who received suprachoroidal UCMSC implantation. Patients were registered if their visual acuity and/or Visual Field (VF) deteriorated despite maintaining good intraocular pressure control with anti-glaucomatous treatments. Evaluations were conducted at baseline, on the first postoperative day and at 1 month, 6 months and 1 year after surgery. Best Corrected Visual Acuity (BCVA), anterior segment and fundus examination, color photography, Optical Coherence Tomography (OCT), Retinal Nerve Fiber Layer (RNFL) analysis, VF testing and Pattern Visual Evoked Potential (PVEP) assessments were performed at baseline and during follow-up visits. Results: All 17 participants completed the 12-month follow-up period. No systemic or serious ocular complications were recorded. The study showed significant improvements in BCVA, VF results, RNFL measurements and PVEP amplitudes at the end of the follow-up period. Conclusion: Although the sample size is limited, suprachoroidal UCMSC therapy appears to be safe, with encouraging improvements. Further studies with larger patient groups and longer follow-up periods are required to assess the impact of stem cell delivery on visual acuity and quality of life in glaucoma patients.
