Abstract
Aim: The photoreceptors in retinitis pigmentosa (RP) remain in dormant status for a while with a decrease in the growth factors in their microenvironment before apoptosis. Growth factors reduce retinal degeneration and apoptosis in animal models. Materials & methods: The data of 188 eyes of 94 patients who were injected with autologous platelet-rich plasma (PRP) into the subtenon space three-times every 2 weeks were evaluated retrospectively. Results: Statistically significant improvements in visual acuity, visual field and fixation stability were detected after treatment. When the treatment response of the patients' better-seeing eye compared with the response of the other eye, there was no statistically significant difference. Conclusion: The PRP treatment has a favorable effect on visual functions in patients with RP. This approach is promising as it is safe and easy.
