“Little old” Adies pupil 

Can you do a video on Argyll Robertson pupil explaining how you would distinguish it from a bilateral "little old Adies"?Thanks

Wow

In practice, I think it is very difficult to test already small pupil (especially with a dark iris) for further constriction by light and near. How do you do it? Cameras?

Sir please buy a mic... So kind of you

$1000 camera upgrade. $2 dry erase marker...?
