  12. Why don’t you have a imbeded player on the site. So that we could take part of the vidoes directly instead of downloading them ?

    • Markus, there IS an embedded player on this page – a Vimeo video, actually. If you can’t see the lecture without downloading, there may be something wrong with your computer, flash, or your network is blocking video sites like Vimeo, Youtube, etc..

  18. Great video! Very educational. Slit lamp is one of the most complex instruments in medicine and you managed to make it simple. Even an idiot like me understood it!

  19. I remember when a Ophthalmology Resident told me “check the patient on the slit lamp, I come later” I didn’t know a thing about the slit lamp. I was that baby thrown to the water.
    Thank you Sir

  20. I am an Ophthalmologist and working as Professor in Govt. PGIMS, Rohtak Haryana India and like your video on Slit Lamp Examination of Human eye. It will be helpfull for both UG and Pg students of Medical Institute.


  22. I might be wrong, probably not, but Dr. Root is likely the best ophthalmic educator and lecturer, like, ever. His presentation is fluid, packed with information, and just so dang funny!

  23. Hi! I’m glad that one of the fellow residence here showed me the root atlas website. I started my residence latter than my colleagues, so I lost lots of classes, and the slit lamp exam was one of them. I’ve tried to learn this subject in some books, but they were very confusing and unattractive. This video was a great teacher for me!!!!

  24. Dr. Root’s Your videos are great I am with the ARMY AIRFORCE EXCHANGE IN GERMANY WE ARE OPENING TWO NEW OFFICES

  25. You are amazing! Such a helpful lecture. Awesome video, along with many funny clips. What a passionate educator, full of positive energy!
