@majinkobe He moves the arrow back and forth because the arrow's meant to represent bright torchlight. You're not meant to leave the torch shining in the patient's eyes for too long. That's why he shines it in for just long enough to see the constriction, then moves it back out for the patient's comfort.
Great video. I am an ophthalmologist in Nevada and would like to use your video for an upcoming lecture. How can I contact you for permission to use this video (one time lecture only) and get a hard copy. Thanks in advance.
"when performing the swing light test in a patient who has a mature cataract there should be an "observed RAPD" in the eye without the cataract."
Yup, its in the books, but its rare. Have you ever seen it? I haven't. The take home message is never attribute an RAPD to cataract, or you will have a very upset patient after cataract surgery.
If you start to worry about "reverse RAPD" you can quickly get tied up in knots about stuff that doesn't matter.
when performing the swing light test in a patient who has a mature cataract there should be an "observed RAPD" in the eye without the cataract.
this is because the mature cataract acts to scatter the light in that eye making the source appear birghter in that eye. when you swing the light to the other eye the source appears reduced and so the the pupils will be more relaxed.
If anything else is observed then there are bigger things to worry about than a cataract.
Great video - explanation of RAPD to non-ophthalmologists is always mind bending, but your video is succinct and clear!

Excellent! (except that you could have "left" and "right", because the patent's left is not "our" left :P )
Keep up this great work and keep posting!

Not to pick hairs but!
