Introduction to Glaucoma Video
This introductory video covers the basics such as open-angle and closed-angle glaucoma. In addition, treatment options, pressure-concepts, and exam findings are shown with full-motion video clips. Overall, I think you’ll find this lecture entertaining.
Screencaptures from this Video:
This video begins with a definition of glaucoma … unfortunately, there are many proposed mechanisms and we don’t truly understand this disease.
To understand glaucoma, you must understand how aqueous fluid is produced and drained from the eye.
One method of pressure measurement is with the applanation tonometer built into the slit-lamp microscope.
The applanation mires should touch – this lets you know that you’re flattening the proper amount of cornea.
The cup-to-disk area increases as less ganglion nerves are traveling through the optic-nerve.
Small cup, and bigger cup.
This Goldman perimeter lets us map out visual fields.
Pachymetry is the measurement of corneal thickness, and works through ultrasound.
Some people have thick “truck-tire” corneas that feel hard at any pressure.
Other people have thin “bicycle-tire” corneas that feel soft.
The chamber depth can estimated with a penlight.
Total internal reflection limits our view of the angle and the trabecular meshwork. A goniolens breaks the cornea-air interface, and allows direct visualization of these structures.
This gonio-video demonstrates the main structures and the trabecular meshwork can be seen as a faint line.
One surgical treatment for glaucoma is a tube-shunt drainage device.
With pseudoexfoliation syndrome, a basement-membrane material forms on the anterior lens capsule. As the iris rubs against this material, pigment is scraped off that clogs the TM.
With bad diabetic retinopathy or a central retinal vein occlusion, VEGF can float forward into the anterior chamber and lead to neovascularization of the iris and angle, creating a dangerous glaucoma.
it is very usuful way of learning by waching this video.
i want video on different type of slit lamp technique ,needed for my exam.
Please tell me about the parts of the chamber when you take the gonioscope: Schwalbe line, trabecular meshwork, scleral spur,and the ciliary body . What is way differ bettween them to confirm the stage of close angle glocome

I just saw this video once. but i can’t anymore. i have tried may be a hundred times refreshing one in the morning, afternoon and evening since 2 days but i cant see the video. then i figured out that the problem was with the website where you uploaded the video. (vimeo.com). Please i have a request if you can upload to youtube or any other video website before 29th of december because i have a presentation on glaucoma. and send me the link. thankyou a million times.
This is an excellent video. I can’t seem to sign up.

Simple, to the point, brief overview of a complex entity. Brilliant work!
very helpful
keep it up
you did a great job.
congratulations
Hi Tim-
Thanks for the wonderful videos and chapters!
You mentioned you had lasik? How myopic were you? I havent’ heard many ophthalmologists who get lasik on themselves.. i’m a -9.00 in both eyes- it seems my options are IOL or nothing?
would love to hear your opinion on this controversial topic!
Very nice. Very educational. And yes, entertaining lecture too ๐
Thanks alot
Great job Dr.Timothy. Thanks a ton.
In the above lecture u mentioned that u had Lasik done. In case of Myopia the axial length is already more and in Lasik reshaping of Cornea is done by burning certain areas of it. I understand that due to certain pressure the axial length increases causing myopia. Does the chance of getting myopic power againg increases after Lasik? Please guide.
thnk u
i am not able to assess the video,can u help sir
thanks a lot sir
Thank you so much for website but the video is not workin.please help me

I’ve spent the last couple of hours on your wonderful site watching video after video after video and had to leave a small note to thank you Dr. Root and anyone else who’s a part of this project. It is so helpful for me, even as a 3rd year OD student. I cannot stress enough how valuable all of your hard work is and how much I’ve benefited from it so far. I wish you all the best and hope that you continue this project because words cannot express fully how much I appreciate all of this.
All the best to you Dr. Root. May you be well and in good health always.
