Meeting of the Open Perimetry Initiative at ARVO '13

We have previously alerted to the subversive activity of the Open Perimetry Initiative who has been on the watch list of our Ministry for a little while (see the post of 17 Nov '12). It now turns out that they will be meeting at the ARVO convention on Sunday 5 May, 1:00 - 2:30 PM, Convention Center room LL3. We believe that this is a serious violation of the perimetric spirit. Perimeters cannot be open - they MUST be closed at least on one end, and ideally ring-fenced all the way around with a fierce and fiery firewall. DO NOT TOUCH THE DATA.
