I was able to meet him and his staff including other physicians and laboratory assistants to evaluate some of the results of the clinical studies being done on retinitis pigmentosa patients using ENKAD (encad) therapy. I examined patients with Dr. Katznelson in the clinic and met with the pathologists to go over the slides and the statistical studies on pre- and post-treatment patients. I was able to visualize microscopic slides of animal studies and the retinal changes demonstrated on these slides of comparing those animals that had received ENKAD (encad) with those that had not.
