Introduction to Glaucoma Video


length: 21:17 minutes

This introductory video covers the basics such as open-angle and closed-angle gluacoma. 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:

video-glaucoma-whatis.jpg
This video begins with a definition of glaucoma … unfortunately, there are many proposed mechanisms and we don’t truly understand this disease.

video-glaucoma-trabecular.jpg
To understand glaucoma, you must understand how aqueous fluid is produced and drained from the eye.

video-glaucoma-slitlamp.jpg
One method of pressure measurement is with the applanation tonometer built into the slit-lamp microscope.

video-glaucoma-applanation.jpg
The applanation mires should touch – this lets you know that you’re flattening the proper amount of cornea.

video-glaucoma-cupdisk.jpg
The cup-to-disk area increases as less ganglion nerves are traveling through the optic-nerve.

video-glaucoma-opticnerve.jpg
Small cup, and bigger cup.

video-glaucoma-goldman.jpg
This Goldman perimeter lets us map out visual fields.

video-glaucoma-pacymetry.jpg
Pachymetry is the measurement of corneal thickness, and works through ultrasound.

video-glaucoma-cornealthickness2.jpg
Some people have thick “truck-tire” corneas that feel hard at any pressure.

video-glaucoma-cornealthickness.jpg
Other people have thin “bicycle-tire” corneas that feel soft.

video-glaucoma-shallowpenlight.jpg
The chamber depth can estimated with a penlight.

video-glaucoma-totalinternalreflection.jpg
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.

video-glaucoma-gonioscopy2.jpg
This gonio-video demonstrates the main structures and the trabecular meshwork can be seen as a faint line.

video-glaucoma-tubeshunt.jpg
One surgical treatment for glaucoma is a tube-shunt drainage device.

video-glaucoma-pseudoexfoliation.jpg
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.

video-glaucoma-neo.jpg
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.

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

Comment by Maria — December 14, 2010



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.

Comment by MUFRACACA — June 9, 2011



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!



Comment by rm — June 19, 2011



Very nice. Very educational. And yes, entertaining lecture too :)



Comment by Sui — July 19, 2011



Thanks alot



Comment by Abdul — October 4, 2011



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.
