That this setting is adjusted for my vision. So before we start the demonstration I need to make sure For this scope you may have to adjust it more for the patient. Unless they're extremely nearsighted or farsighted. Otherwise one last thing to mention: if you're a healthcare providerĪnd you're very nearsighted and you have to adjust this for yourself, usually youĭon't have to worry about the patient being nearsighted or farsighted with the pan optic This knob here correlates very well with this knob hereĪnd this setting here that you adjust for near-sighted and far-sighted is very Remember is that the pan optic scope is actually very similar to the more traditionalĭirect ophthalmoscope. Who's nearsighted or having difficulty seeing far away, another thing to Knob until it comes in focus and if it comes in focus a little bit towards the red setting that's actually your Through the scope at something about ten to fifteen feet away and move this Used to figure out what your prescription is. Your patient is too nearsighted or too farsighted this setting can actually be Purpose of this third setting is to focus-if you the health care provider or Right now the third and final setting to know about the pan Is to see better contrast on the red blood vessels in the back of the eye. There's a green light that comes out and that's To look at abrasions on the cornea if you add a Fluorescein dye. The second thing you can also see is a blueĬertain come with that and certain don't, so if yours has that, it allows you Tiny slit lamp to look for variations in contour. If a patient's more dilated or more constricted you can check it. To the left you'll get varying sizes of that circle, a larger one or a smaller If you slide the green line to the right or This green line will provide a medium-sized circle which is The second thing to know about the ophthalmoscope is thisĬarousel setting right here and this carousel setting allows you to change theĭifferent types of light coming out of the scope, so the most important thing Won't be able to visualize the retina as long. Number two: the brighter it is the more painful it will be for the patient so you One: the brighter you make it the more pupil constriction you may get if you're Press the little button and twist it and the more you twist it the brighter the So for the brightness all you need to do is Now for the ophthalmoscope there's three main things to know. The mechanics of using the pan optic it's essentially the same thing as this ophthalmoscopeĪs well and we'll talk about that in a second. Now I should also mention while we'll go over It's easier to use and two, has a greater field of view. Of this video we're going to be mostly sticking with the pan optic because one, You have the traditional one here and also the pan optic. In a couple different forms and twoof the most common ones I'm holding in my Ophthalmoscopes are the type of gear that the eye specialists wear on their Want you to also be comfortable doing the same thing so that's the purpose ofīefore we can do anything else we have to talk about the equipment. However if you're taking care of a patient we Of eye doctors as the ones who are looking in patients’ retinas. Teach you the approach to looking at your patient’s retina. School of Medicine, a hospitalist and also a member of the Stanford Medicine It is essential that the screening process should be made as convenient as possible for diabetic patients. Screening for diabetic retinopathy is only effective if it achieves high coverage (at least 80% of known diabetics). If retinal photography is not possible, then the fundus may be examined by the diabetic physician, an optometrist, or an ophthalmic assistant. In most developing countries there are too few ophthalmologists for every diabetic to be examined annually by an ophthalmologist. The quality of digital photos is not as good as conventional film, however, they are quite adequate for retinopathy screening. Digital fundus photography is expensive initially, but has very low running costs as it does not require film or developing the pictures. The photos allow an ophthalmologist to examine a large number of eyes very quickly. It has been shown that fundus photography is the most accurate means of screening for retinopathy. The fundus may be examined by ophthalmoscopy, using a slit lamp and either a contact lens or a 78D lens, or by retinal photography, which may use conventional film or a digital camera. Preventing blindness from retinopathy relies on early detection of asymptomatic disease by fundus examination. Diabetic retinopathy does not reduce vision in its early stages, when treatment is most effective.
