Argus II Investigator Meeting

A meeting of investigators of the Argus II Retinal Prosthesis held on March 28, 2015, drew over 50 physicians and scientists from around the world to the Kellogg Eye Center.  Attendees were also connected by video web-conferencing to speakers in the Middle East, Europe, and at other sites in the United States.   

Organized by K. Thiran Jayasundera, M.D., Kari E. Branham, M.S., Ashley Howson, M.S., OTR/L, Naheed W. Khan, Ph.D., and David N. Zacks, M.D., Ph.D., the gathering explored criteria for patient selection, surgical techniques, assessment of outcomes, and issues of device programming and visual rehabilitation.  

Topics that generated special interest were implantation in patients with retina staphyloma, performing OCT segmentation of the inner retina for ideal patient selection, device and surgical technique alterations to reduce adverse events, and development of objective functional outcomes and correlation to device programming outputs.

Attendees expressed their pleasure in learning about successes and problems that other teams have encountered.  They were also impressed with the superb organization of the meeting and agreed that future directions must include forming a Listserv among investigators to discuss patient issues, and performing collaborative research projects such as developing sophisticated outcome measures for the prosthesis.
