Ozone Treatment in Retinitis Pigmentosa: Effect on Photo Stress and Contrast Sensitivity

Robert H. Marmer, MD, & Susan Parks, COA


For 15 consecutive days, 200 cc of blood were collected, mixed with 
ozone gas, and reinfused 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
