Implantation of a retinal prosthesis system (Argus II, Second Sight Medical Systems) in patients with retinitis pigmentosa (RP) is safe and is providing some encouraging results when considered from the recipient’s perspective. Careful patient selection, however, is important and should consider the need for compliance with an intensive postoperative rehabilitation process, said Stanislao Rizzo, MD, at the inaugural Retina World Congress.
Dr. Rizzo, professor and chairman, Department of Ophthalmology, University of Florence, Italy, reviewed outcomes from the 30 patients with RP he has implanted with the Argus II. He noted that only four (13.3%) severe complications were encountered.
Satisfaction and willingness to undergo the procedure again were investigated in a subgroup of 20 patients who had completed at least 1-year of rehabilitation. Dr. Rizzo described the overall patient satisfaction rating as “very good”—the mean score was 6.8 on a scale of 0 to 10—and three-fourths of the patients said they would have the procedure again.
