Management of Retinitis Pigmentosa Via Combination of Wharton's Jelly-derived Mesenchymal Stem Cells and Magnovision

Summary

Purpose To investigate whether the natural progression rate of retinitis pigmentosa (RP) can be decreased with subtenon umbilical cord Wharton's jelly derived mesenchymal stemcell (WJ-MSC) application alone or combination with retinal electromagnetic stimulation (rEMS). Material and methods The study included prospective analysis of 130 eyes of 80 retinitis pigmentosa patients with a 36-month follow-up duration. Patients constitute 4 groups with similar demographic characteristics. The subtenon WJ-MSC only group consisted of 34 eyes of 32 RP patients as Group1; The rEMS only group consisted of 32 eyes of 16 RP patients as Group2; The combined management group consisted of 32 eyes of 16 RP patients who received combined WJ-MSC and rEMS as Group3; The natural course (control) group consisted of 32 eyes of 16 RP patients who did not receive any treatment were classified as Group4. Fundus autofluorescence surface area (FAF-field), horizontal and vertical ellipsoid zone width (EZW), fundus perimetry deviation index (FPDI), full field electroretinography magnitude (ERG-m) and best corrected visual acuity (BCVA) changes were compared within and between groups after 36 month follow up period.
