The Cubans claim they are treating RP successfully. A Canadian ophthalmology journal casts doubts.
One controversial treatment, currently available in Cuba, consists of a combination of ozone therapy (removing a small amount of blood from the eye, adding ozone, and replacing it a short while later), electrical stimulation, dietary supplements and so-called “oligoelements”, and eye surgery under a local anesthetic. The rationale behind these procedures is to improve the supply of oxygen and nutrients to the affected parts of the eye.
As yet, this procedure has not been subject to critical review and, as such, remains outside the medical mainstream. The Cuban clinic where it has been performed has repeatedly refused to show the procedure to anyone outside of the clinic. As such, critical review is very difficult. There have been reports of physical damage to some patients including detached retinas, crossed eyes, and sensitivity to light.
