Eye Exam Tricks for Tricky Patients
This video discussed advanced eye tricks you can perform on those “difficult” patients (malingerers, neuro disorders, and myasthenia gravis). This was recorded at an ophthalmic tech conference several years ago, but I’ve recently updated the slide-graphics and cleaned up the audio. Enjoy.

The techniques for confirming fictitious blindness are discussed, including the handoff and shake.
The optokinetic drum and flag are used. Most people believe that your vision must be 20/200 or better to see optokinetic nystagmus.
Finger touch proprioception testing is shown. The pinhole PAM (potential acuity meter) test is then demonstrated (very useful before cataract surgery).
The entoptic phenomenon (Troxler fading or Purkinje effect) is shown. Then pencil field testing to determine macular sparing lesions.
Myasthenia Gravis can be detected with the upgaze test. The ice-pack rest test is shown as well.
Determining the dominant eye before surgery with the “ocular dominance test”
Is it not called entoptic phenomenon rather than photoptic phenomenon?
Yep, the “entoptic phenomenon” it is. I couldn’t remember the name or find it anywhere online when I prepared the lecture. It has also been described as the “Troxler’s fading phenomenon.” Thanks for the comment!
I learned it as “Purkinje images” or more more accurately as the “Purkinje tree”. Love your lectures!!! Thanks so much!
Its wonderful very vital info thanks so much
seen it all now just took a lot of time to load. Thank you soo very much

Great video- thanks! You have an excellent gift for teaching. I believe the photoptic phenomenon you mentioned is called the troxler effect.
I’m looking forward to buy your book in order tu support your hard work.
All the stuff published here is extremely useful, and i really aprecciate it.
Thanks to all the people who made this!
HAHAHAH HE IS SO GOOOOOOOOOOOOOOOOD!!
Great stuff – I plan to study medicine and wouldn’t have particularly have gone to Ophthalmology but I am glad to have come across it. Interesting and fun stuff.
@Miss Marlene M.D – it is very stupid to post your site on this one promoting a subscription service for Medical Advice. Not only is it annoying, it promotes self diagnosis which in most cases can and will lead to further problems.
Respect this as an Educational free source of information.
Great stuff.
Regards.
happy way for studing
