Marmer, Robert H. & Susan Parks, Ozone Treatment in Retinitis Pigmentosa: Effect on Photo Stress and Contrast Sensitivity. Annals of Ophthalmology 30: 164-166, 1998.
For 15 consecutive days, 200 cc of blood were collected, mixed with ozone gas, and rein fused into a retinitis pigmentosa patient. Contrast sensitivity and glare recovery testing were performed before initiation and following completion of this treatment program. Not only were contrast sensitivity and glare recovery significantly improved, but enhancement in the patient’s performance in low light conditions was documented. IV administration of ozone at four- to six-month intervals appears to be an effective therapy to enhance visual capabilities in RP patients.
