This is the first half lecture on retinoscopy ... the technique we use to check prescription in children. This is a hard skill to teach, so hopefully you'll find these animations useful. You can find more lectures like this at ophthobook.com
Did not know that Tom Cruise was an eye doctor but excellent video all around!
a mix between Tom Cruise and Jason Bateman :)
O was thinking same
😂👍

Thank you SO much for this video! I’m a COA working towards my COT & this was incredibly helpful!
Dr. Tim Root Ur lectures are best and easy way to Understand in Ophthal.
this video was so helpful & the way he preferred to do multiple examples w negative & positive power values was so helpful in clearing any doubts about the subtraction that may have been!
Thank you so much for your work! You are a superb educator! From an Optometrist
I’m currently a first year in optometry school, & were using gill strand eye. Y professors, tho they’re sweet, confused me so much. Thank you for clarifying the confusion of this simple skill
I can say that as a med student, I find this lecture to be very good! Thank you a lot!
Awesome! My lecturer just had all words and expected us to visualize but the whole lecture was a disaster cos I didn't really understand what is happening. This video is very concise and understandable! Thanks for the images and video
Thank you Mr. Cruise. A very nice video and a very thorough explanation. I just wanted to say I'm happy you developed such a passionate interest for an actual science like medicine. I was sure that little affair with the scientologists' church was just a passing fancy. Good for you.
It was best video i hv seen,straight to the point and explained very well
Thank u very much
2 hours reading my college notes and it's all nonsense. 2 minutes watching this video and it's all seeming so obvious.

Thank you so much for this video … I am a medical student and could never understand retinoscopy untill now.
This is the best learning tool I have had to learn retinoscopy. Thank you very very much for making this so readily available.
There's no better illustrating video than that... excellent 👏
Wowww great video I’m a future optometry student and the eye doctor I’m working with let us play with the retinoscope and this video really explained the details very well

Beautifuly explained👍👍

Good job Dr
That was an awesome presentation. I was really confused with this instrument .U had made it very easy ..thanks a lot
To get comfortable in retinoscopy you'll need to do it everyday in about 7 years.
Thank you so much Dr sharing for this video very simple to understand how can do retinoscopy
What a wonderful presentation. I am an "Engineer" and I always wondered how this was done -- EXACTLY. Thanks, Otis
excellent lectures & easy to understand
You have simplified it for me👌🏿👌🏿
Excellent, always wanted to know how it was measured.
Thanks a lot

Excellent presentation
Thank you so much, i was all tangled with this thing and your video helped me to clear it up just like that.
Excellent. Thank you very much.🤗🤗🤗🤗🤗
Please share a vdo of how to find the cyl axis
love you so much!!! Great lectures ever! Waiting for your new lectures!
This is an awesome lecture, but how does it change when you don't have positive cylinders? I'm studying Ophthalmology in Guatemala and here we only prescribe lens with negative cylinders. Thank you very much for the lecture, I've found all lectures very useful. Keep making learning fun.
u said in the video that optometrists do it differently. may I know what do they actually do differently? I'm just curious to know the difference between both the doc n optometrist's practice in retino
so good 👍
@fofocientos
Agreed ... but I would argue that your description is the same thing as described in this video. It's ALWAYS about vergence of light ... whether we are describing converging light (as in this lecture) or coupled optical systems (like you are describing). I prefer the simpler explanation, and try to avoid discussing real/inverted images, far points, and terms like puntum remotum because they don't help someone learn retinoscopy. Appreciate the input.
@MarkDavidKnight for a 66 cm working distance its subtract 1.50 DS (1/66cm =1/0.66m=1.50)
VERY HELPFUL
Thanks for the upload
Gratitude from India🙏🏻🙏🏻
Pretty Refreshing...and to the point.. Thanks Tim :)
A real problem with children is that you must have the child "look in the distance". If the child looks close (accommodation for 20 inches) you will get a measurement that is 2 diopters more plus than in should be. With adults you can instruct them to "look in the distance", and that will provide an accurate measurement.
what a brilliant lecture
Thanks for this video, really useful. I'd like to make a cardboard model just like yours. Could you please tell how you did it?
Love your videos! Thanks for sharing you knowledge!
Hi! one question, how should the light be ? thin or thick?
thanks!
very informative, and easy to understand
thank you very for sharing the great video.. very good job doc!
Dear sir, can you please tell which type of retinoscope using in this video
THANK YOU DOCTOR 💟
This is excellent! Such a good explanation :D
Great video!!!

Sir i have problem with neutralise the cylindrical power..
Speacilly when it is oblique..
Please give a trick for it.
We explain about hw to neutralize cyl. Oblique axis watch our retinoscopy part 2 video for more info.
Dear tim root! I have confusion in this topic,
As i know when we want to neutralize a plus power spectacle we put a minus on it and vise versa so in retinoscopey it is something different when we find a with motion we put plus power to neutralize...? 🤔
Thank u so so much sir ....finally i got the idea...

too good you made it lot easier thank you
Could you explain some examples of negative cylinder power? There is no example for that in your videos (1or 2).
Please reply or record and upload a new video !
Thanks in advance
very helpful ,thanks lot
Its v.v.very usefull. thanks sir.
I think there is just one mistake, when he founds minus sphere, he should ad +1,50 in correction, not - 1,50
Thanks a lot for a wonderful xplanation.
i am optometrist.your video good
Thank you so much
Very useful 👋 thank you so much
Thank you
Thank you so much doctor 😍😍
nice explain
Really nice video, Thanks!
u are vera level sir..
Thank you. It is very cool video) I almost understood the retinoscopy)
HI TIM SIR.......PLEASE ADD SOME MORE VIDEOS
LOVE FROM INDIA......
Good afternoon sir ,I have a question , why minus working distance for example 1.50,2.00,1.75 into retinoscopy
Dear mr
I'm want to take your video and make a caption in Arabic
I wish you accept
With my best wishes for a good future
Mr. Ahmed Riyad
Hi Dr. Thanks for the lectures, but isn't working distance 2.50 and not 1.50? Thanks Dr
I have a doubt though, why is with movement seen even with emmetropia? I understood it with hypermetropia.
That's awesome.. 👌🏻
great video... I have just one question... Can I use an ophtalmoscope instead of retinoscope? What's the difference between ophtalmoscope and retinoscope?
thanks, now I understand :)
thanks very much
thank you!!
Would like to seek permission to borrow clips (edited down into short segments or .gif files on my end) for my website. Properly sourced and linked to this main video of course. Couldn't find any other way to appropriately ask but through this comment section...
That's fine as long as it's linked to original and not used in a disparaging way or in a paid product. Thanks.
Wonderful! Thank you!
Amazing video. Thanks!
Thx from Bangladesh
THANK YOU!!!
very good
Thanks a lot for your demo. Retinoscopy was impossible to visualize from the textbook in my final year med school .
