In his January 1997 Archives "Letter to the Editor," Dr Peláez1 claims that the process by which Berson et al2 published their May 1996 Archives article was not fair or ethical. I do not share Dr Peláez's opinion and believe that it is necessary to mention at least 2 aspects of my experience with fairness and ethical behavior of the Cuban therapists in respect to their patients.
1. Dr Peláez systematically undermined our attempt and the attempts of other researchers trying to study the effect of treatment by convincing his patients that an electroretinographic examination within the first 6 months after therapy would wreck the therapeutic effect. Therefore, almost all German patients with retinitis pigmentosa did not participate in the postoperative control examination involved in our prospective study of the Cuban therapy. A scientific argument for the irrational insistance of harm from electroretinography is lacking. The question arises
