Great info and descriptions. In the past I have used the MacHole preset,
but in this situation as in so many now, I have no idea what diagnosis
might be, nor have much time to pull up the patient's EMR etc.  I know
better and should have picked up on the faint window defect and repeated
the OCT, but doing upwards of 14 FAs and 20 OCTs per day, honestly,
justifiably I need more specific imaging directions.  Quality in, quality
out so thanks Jocelyn!
