Ophthalmology Lecture Videos

Here are the first nine videos (I’m still working on the last cataract lecture). These videos correlate closely with the book chapters, and the full-motion video/animation segments should help clarify things!

These videos are streaming flash video from Vimeo (a website like youtube). Once the entire series is completed, I’ll likely reencode them and place them in the iTunes podcast directory for download and portable playback. One thing at a time, though.

I hope you enjoy these!

Video 1: History and Physical
Format: Vimeo stream, length: 18 minutes
An introduction to the eye exam, checking vision, pupil defects, and how to interpret the slit-lamp exam. The second half of this video has some great microscopy video-clips.
Video 2: Anatomy of the Eye
Format: Vimeo stream, length: 25 minutes
The eye is a complex structure, but this lecture makes it look simple! This video came out a little longer than expected, but it’s all high-yield with great video clips, color cartoons, and full-motion CT scans.
Video 3: Glaucoma
Format: Vimeo stream, length: 21 minutes
An important subspecialty, this video shows you the types of glaucoma, important slit-lamp/retinal findings, and the medical/surgical options for treating.
Video 4: Retina
Format: WMV, length: 16 minutes
The retina is normally a difficult subspecialty. In this video we cover anatomy, diabetic retinopathy, retinal detachments, and macular degeneration – short and high-yield info!
Video 5: Infection
Format: Vimeo stream, length: 22 minutes
This video illustrates the important infections involving the eye: including conjunctivitis, blepharitis, HSV infection, pre-septal cellulitis, and endophthalmitis.
Video 6: Neuro-Ophthalmology Parts 1 and 2
Format: Vimeo stream, length: 25 minutes, 27 minutes
The neuro section can be confusing, so we’ve broken it into two seperate lectures. This first concentrates on eye muscles and cranial nerve palsies.
Video 7: Pediatric Ophthalmology
Format: Vimeo stream, length: 23 minutes
This video is loaded with great pediatric tips – checking vision, retinoscopy, prisms, amblyopia, leukocoria, and retinopathy of prematurity! Super high-yield!
Video 8: Eye Trauma
Format: Vimeo stream, length: 28 minutes
In this video I review a series of common ocular trauma seen in clinic and the emergency room. Lots of useful video and tips on treating these emergencies.
Video 9: Eye Optics
Format: Vimeo stream, length: 24 minutes
This lecture covers all the basic eye optics I wish I’d known when I started my training! All the basic concepts you need to write or analyze a glasses prescription.

Live Lectures
These lectures were given live before an actual audience. As such, they don’t follow the ophthobook quite as closely. On the other hand, these lectures are quite a bit funnier. Enjoy!

Super Eye Palsies
Format: Video stream, length: 29 minutes
A review of the extraocular muscles and the various cranial nerve palsies (3rd, 4th, and 6th nerves) that cause double vision.
Exploding Eye Lecture
Format: Vimeo stream, length: 28 minutes
Traumatic eye experiments (such as penetration testing with airsoft and paintball guns) used to understand eye injuries.
Comparative Eye Anatomy
Format: Vimeo stream, length: 22 minutes
Examination of the various eyes found in the animal kingdom, and what they can teach us about the human eye.
Slit Lamp Eye Exam
Format: Youtube stream, length: 24 minutes
Funny video review of the slit-lamp microscope and the components of the microscopic exam.
Pediatric Eye Exam
Format: Vimeo stream, length: 10 minutes
A short and humorous review of the child exam. This lecture is entirely full-motion video and covers vision testing, congenital glaucoma, and tips for looking at toddlers.
Tropias and Phorias
Format: Vimeo stream, length: 18 minutes
A simplified approach to eye-movement disorders. This animated lecture uses cartoon motions to demonstrate techniques like the cover-uncover test.
Loose-Lens Retinoscopy
Format: Vimeo stream, length: 24 minutes
This is the ultimate guide to retinoscopy for the newbie. While retinoscopy is the hardest skill to learn, these animations make it look easy!
Introduction to Cataracts
Format: Vimeo stream, length: 15 minutes
This short, concise lecture discusses cataracts, historical surgery advances, modern technique, and new implant options. Very interesting with many cartoon animations during the second half.
Cartoon Cataract Surgery
Format: Vimeo stream, length: 8 minutes
An animated and live-video guide to cataract surgery, with step-by-step instructions. Perfect for the student watching their first cataract surgeries.
Twenty Exam Tricks
Format: Vimeo stream, length: 15 minutes
This lecture was given at an ophthalmic tech conference, and covers eye “tricks” you can use for your difficult patient. Everything from optokinetic drums to pencil testing. Pretty funny, and a different style than the our other lectures.
Eye Trauma
Format: Vimeo stream, length: 24 minutes
In this lecture, I discuss eye trauma, kung-fu movies, and his elephant coffee. A humerous and video-intense approach to common eye injuries seen in the emergency room.
Optics Schmoptics
Format: Vimeo stream, length: 26 minutes
A review of optics basics. I discuss the pinhole eye in nature, diopters, Snell’s law, and other common focus problems in the clinic.


Outstanding, I just went through the 5 videos and I’d say I learned as much as I did in my 2 weeks in ophthalmology in my medical school.
Looking forward to seeing the other 5 videos and downloading the flash cards.

Give yourself a big pat on the back!:) You deserve it.

Comment by Daniel Wilson — February 8, 2009

awesome videos!…theres a mistake in the neuro part II video though. it says loss of parasympathetics (thus pupil constricts)…i think you mean thus pupil dilates

Simply awesome… Thank you!!

Comment by LA — March 29, 2009

thanks, that was just awesome !!! i learned while watching one video, more than i did during two weeks in the ophtalmology department. keep going and thanks again

Comment by mounim — April 20, 2009

When will you cover Cataract, Errors of Refraction, Iridocyclitis, and Endophthalmitis?

Editors Note: I’m making the videos in order of the book chapters. Trauma will be next, followed by optics (refraction), then finally cataract. The book doesn’t cover iridocyclitis (except a brief mention in the trauma chapter). Endophthalmitis was briefly discussed in the infection chapter/video. Thanks for the interest!

Comment by prep4md — April 29, 2009

Thank you for having these available, I wish I could get them for every specialty! It’s made my ophthal revision so much easier.

Dr. Root, I was at JOMA today and really appreciate the videos and cartoons you have put together. It’s a great help for techs to be able to put a real picture and even better video with the names we hear about all the time!

The retinoscopy video is great! PLEASE PLEASE do one for a complete retinoscopy with jackson cross and cyl!! Retinoscopy has been my nightmare and would love to refine my skill. I’ve watched MANY videos and demonstrations and none did as well of a job as you did on the basics of retinoscopy! Thanks again! This is a great site!!!

Tim Root: Deepak, thanks for bringing this to my attention. I haven’t been able to recreate your problem, but once a year I get feedback about videos halting half-way through. This may be related to how the videos are embeded. If you have this problem, I recommend going directly to Vimeo, and trying watching my videos there. Here’s the link to the lectures:


I’m working on creating a podcast stream, so you can actually DOWNLOAD each of the lectures to your computer and watch on iphone/ipad. Sign up to the email update newsletter (the blue box under the navigation) if you want to be uploaded when this is working. Thanks!

Comment by Dean — September 17, 2012

These vidios are wonderfull. Not only for Developed countries but also for those people of backward countries who wish to learn and have enough resources but country- wide there is no opportunity to get education about optometry. I am thank full to the whole organization who is involved in this activity. Specially, the tutre and his style of teaching is outstanding.

Thank you so much for these outstanding videos! They were the key for integrating my readings. You explain it in such an easy way that when you think about it you ask yourself: “Why hadn’t i taken THAT in consideration before!!??”. It takes A LOT of expertise to explain difficult subjects so easily.

Greetings from Mexico!

Watched some of your videos, helped a lot in getting the basic concept! Thanks for that. Can you add something on the basic theory and pathology following topics:
Uveal Tract, Sclera, Eyelids, and Conjunctiva?

Also, can there be a video on detailed examination procedure of the eye? I couldn’t find that.

Comment by iGuy — October 8, 2013

@ iGuy: You can find most of these topics spread throughout the book chapters and videos. As for a detailed examination procedure for the eye, I would watch my slit-lamp exam video and listen to this hour-long audio lecture over at eyetalkradio: Intro to the Eye Exam.

Dr. Root I can’t thank you enough for taking the time and effort to make these videos and chapters.

Thanks a gazillion again!!!

Thank you for every effort you have put to make this project available to help the medical students, or even seniors.
Love you!
