Ophthalmology - Retinoscopy (Part 1/2)

www.ophthobook.com
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!

[@cherylchapman4108]

a mix between Tom Cruise and Jason Bateman :)

[@taibatahir9704]

[@Ottehgstar]

2 hours reading my college notes and it's all nonsense. 2 minutes watching this video and it's all seeming so obvious.

The best explanation by far !! Thank you so much .

[@ollur2257]

Thank you so much Doctor for sharing your knowledge..... You have very good skills at teaching....... Greetings from Algeria

[@chariswalton9635]

Thank you SO much for this video! I’m a COA working towards my COT & this was incredibly helpful!

[@fkeopfkeop]

To get comfortable in retinoscopy you'll need to do it everyday in about 7 years.

[@akash_sky384]

Your videos are very helpful, interesting, and your teaching style is awesome. I Love your videos keep making, always waiting for your videos

[@thecryptoguy8381]

You have simplified it for me👌🏿👌🏿

[@mar7956]

all make sense !! like your videos

[@Panwarbook]

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

[@sahelisarkar4516]

Please share a vdo of how to find the cyl axis

[@pahadiexploreruk1235]

Sir i have problem with neutralise the cylindrical power..
Speacilly when it is oblique..
Please give a trick for it.

[@optometrygoals5877]

We explain about hw to neutralize cyl. Oblique axis watch our retinoscopy part 2 video for more info.

[@sanpras1647]

VERY HELPFUL

[@syllamalvi2752]

very informative, and easy to understand

[@riverremis69]

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

[@sarojmandal4739]

excellent sir

[@srinivas3241]

Dr. Tim Root Ur lectures are best and easy way to Understand in Ophthal.

[@otissumnerbrown]

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.

[@milisharma920]

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!

[@gytistijunelis3653]

I think there is just one mistake, when he founds minus sphere, he should ad +1,50 in correction, not - 1,50

[@emehdoris8882]

Thank you very much for this video
I can’t believe I ve been wasting my time trying to understand my textbooks 😫😫

[@alishmedic6396]

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

[@TimRoot-dotcom]

@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.

[@ohfifi]

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

[@rameeshas8120]

THANK YOU DOCTOR 💟

[@echafaud]

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.

[@Fernando-jz1zi]

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?

[@Studying-s2g]

Thank you

[@AIIMSONIANSETHI]

Thanks a lot for your demo. Retinoscopy was impossible to visualize from the textbook in my final year med school .

[@emilybodkin7927]

Thank you so much for these videos im finally understanding this skill was so frustrated before viewing thank you so much for ur wonderful videos!!!

[@histymsany1701]

Thank you sir

WELL DONE DR. .....YOUR BRIGHT & YOUR BRIEF --- TOM CASEY O.D.

[@uthmanuthmanuthmanuthman9397]

u are vera level sir..

[@anashwarajacob6615]

I have a doubt though, why is with movement seen even with emmetropia? I understood it with hypermetropia.

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

[@iamsanjaysaini]

Dear sir, can you please tell which type of retinoscope using in this video

[@mahfa7513]

thanks for this video very helpfull I was very confuse how can use it . Thanks god bless you

[@aasmaansari3190]

I am confused your patient and about you.🤔🤔 here's errors chance.

[@drckie6326]

If you begin with ''with'' motion, the patient is gonna try to accommodate and it will false the results.But if you begin with ''against motion'' than the patient won't accommodate and it's going to be more precise.

[@ondrejpolicar6313]

That is what i thought. Can anybody explain why Dr. Root want to try with motion?

[@zacharymorreau1425]

you want to neutralise accommodation by giving atropine or other sedative eye drops. the pupile also widens making the exam easier

[@nileshgaikwad2156]

HI TIM SIR.......PLEASE ADD SOME MORE VIDEOS
LOVE FROM INDIA......

[@cristobalmoctezuma3818]

Hi! one question, how should the light be ? thin or thick?
thanks!

Thank you so much for this video … I am a medical student and could never understand retinoscopy untill now.

[@studdaegang7972]

I was so confused when I read my textbook. You made it seem like a cakewalk. WOW

[@mujeebmoheb4409]

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...? 🤔

[@jaykumarpresswala5621]

It was best video i hv seen,straight to the point and explained very well
Thank u very much

[@tbg1199]

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...

[@TimRoot-dotcom]

That's fine as long as it's linked to original and not used in a disparaging way or in a paid product. Thanks.

[@Samraaa5]

Beautifuly explained👍👍

Hi Dr. Thanks for the lectures, but isn't working distance 2.50 and not 1.50? Thanks Dr

[@adenmadi]

-10 years ago ??!!wow!

[@2mbilal]

@MarkDavidKnight for a 66 cm working distance its subtract 1.50 DS (1/66cm =1/0.66m=1.50)

[@int3rc3pter]

very helpful video thank you soo much.3hr lecture i left confused and not very optimistic for my test .. now i understand and feel a little more confident with how this works.

[@mocha4091]

There's no better illustrating video than that... excellent 👏

[@qwertyqwe7706]

Learn @ 0.5 x speed

[@sixrodas]

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.

[@basmahelal6649]

very good explanation with the animation...
Good job Dr
