Had a great time at AAO giving 8 presentations/courses with wonderful colleagues and friends!

I had a great time talking with Drew Carey, Eye MD, and have to give a shout out to Sinan Akosman for spearheading the project and Mehdi Tavakoli for co-mentoring. Can’t wait for our upcoming PCORI funded clinical trial on early PLEX for severe ON and TM with co-PI Elias Sotirchos!
