Hi Steve,

If your question is in reference to the OCT-C portfolio requirements,  
applicants are instructed to use 1-1-1900 as the D.O.B. on all submitted 
images.  Although I think this date itself has no particular meaning, I believe 
using this date is a uniform way for all applicants to de-identify the 
patient's actual birthday. 

Unless, of course, there is a 114 year old person somewhere in the world who 
just happens to have been born on January 1st! Then we may want to consider a 
different date.   ; ) 

Gary

I have quite a mundane question that as a group, we are split on. Under the 
naming convention for OCT, do we enter the applicants birthday or is 1-1-1900 
simply used as a signifier to satisfy the software requirements.
Thanks

James,

I figured that. I'm going to try everyone's suggestions this week and hopefully 
my eyes will cooperate.
