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.

Conditions

Interventions

BIOLOGICAL

Wharton's jelly derived mesenchymal stemcells

The WJ-MSCs suspension from the culture was delivered to the operating room by cold chain and used within 24 h. A total of 1.5 ml of the WJ-MSC suspension was immediately injected into the deep subtenon space of each eye.

DEVICE

Magnovision

Specifically designed helmets producing high-frequency repetitive electromagnetic stimulation (MagnovisionTM, Bioretina Biotechnology, Ankara, Türkiye) stimulated the retinas and visual pathways in both eyes.
