PRP should be prepared by collecting a total of 8 ml of venous blood from the arm into a sterile citrated
PRP tube. After centrifuging at +4°C and 2500 rpm for 8 minutes, the lower 1/3 of the plasma in the tube is
drawn into a 2.5 ml syringe and a total of 1 ml of PRP is obtained. Then, 0.5 ml of erythropoietin is added to
the same syringe. A total of 1.5 ml of the solution of the citrate, exosomes and erythropoietin mixture is
injected into the subtenon space. This process is repeated for 3 sessions in 2 months between 1 month
interval. Platelet-rich plasma (PRP) containing neurotrophins neurotrophic growth factors to increase the
neural methabolism and reactivating the dormant photoreceptors. Erithropoietin increase the neuroal
capillary density and blood flow. Electromagnetic iontophoresis (MagnoVisionTM) is essential for growth
factors and molecules injected into the sub-tenon space to pass into the sub-retinal space. MagnoVision
also facilitates the passage of these systemic drug molecules across the blood retina barrier.
