Ophthobook questions pdf download
This introduction to the ophthobook questions pdf download covers all the basics: anatomy, diabetic retinopathy, retinal detachments, and macular degeneration. This is a lot of topics, so I’ve tried to keep things simple and to the point. The video begins with a basic review of retinal anatomy.
The key point here is that the photoreceptors lay pretty deep in the retina, with the ganglion nerve fiber layer superficial. The underlying choroid provides nourishment for the photoreceptors. The slit-lamp is the best way to view the posterior pole. This full-motion video segment shows the kind of view you can expect when using a 90-diopter lens. Indirect ophthalmoscopy is useful for viewing larger areas of the retina. The field of view is much greater and lets you look all the way out in the peripheral retina.
This full-motion ultrasound demonstrates all the important eye components. Dot-blot bleeding is discreet because they occur in the deeper, vertically-arrayed layers of the retina. Flame hemorrhages are larger because they occur in the superficial nerve-fiber layer. With large areas of ischemic retina, diabetics produce VEGF to stimulate angiogenisis. The new blood vessels can bleed and create traction. PRP, or panretinal photocoagulation is performed to kill off ischemic retina and decrease VEGF production. Despite other problems, it’s macular edema that actually causes of majority of diabetic vision loss.
When treating retinal detachments we follow the rubber-band theory. Pneumatic retinopexy can tamponade superior breaks. Macular degeneration is a leading cause of blindness in our country, and this video segment describes how it occurs. Timothy Root is a practicing ophthalmologist and cataract surgeon in Daytona Beach, Florida. I can view the video on every computer I have tried. If you’re having problems viewing this video, you may be on a mac system or have older hardware without the corect wmv codec support. Simple and educational at the same time.
You may note that the sound is a little low on these earlier lectures. Hopefully, the educational content will make up for everything. I hope u’ll continue doing it. Thanks so much for taking the time to make this site and for making it free! I must confess that you are God sent!
