I am a student and it was my first time presenting at a conference as well. Ubiquitous, what poster did you present? I'm sure I probably saw yours at some point. I was at poster #3855, if you want to look it up. Anyway, I agree ARVO was an amazing experience. The current depth and magnitude of research in ophthalmology is unbelievable. It's impossible to know it all, but I tried to glean as much from the presentations as I could. I did enjoy communicating with some of the presenters, and later I even met some of the first authors I had referenced in my poster! Yeah, basically it was a big schmooze-fest.
Overall, this definitely fueled my enthusiasm for the field even more. It was a great little getaway from school. Plus, you can't beat lying out on the beaches of Ft. Lauderdale. If you have the chance, it's something I would recommend anyone to attend.
