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

Hello Dr, congratulations for this website, it’s the most comprehensive resource in ophthalmology. It took me shorter time to understand many subjects than at the medical school!!!

Glaucoma never made sense to me until today!

Hello, I really enjoyed watching your video about this topic and I would like to ask if you could send a copy of this to my email address since I would like to show this during my reporting on this topic.

It would really help me a lot to have such permission to have this video incorporated in my report. It is so comprehensive and I really like it a lot
