A treatment recently developed in Cuba for Retinitis Pigmentosa whereby 200 cc’s of blood is collected, ozonated, and is reinfused into the patient on 15 consecutive days was found to increase contrast sensitivity, enhance color perception, augment glare recovery, facilitate function in low light, and in some cases expand the visual field. If repeated every 4-6 months it is claimed that progression of the disease can be slowed or stabilized.
