Whenever you're looking at someone's retina you have to make sure that your So the other important thing to keep in mind is patient positioning. Sure the setting here is at zero and we leave it at the green setting, the medium-sized All we do is simply turn on the phone, make Looking at the retina when they're going in there to do that.

Just putting it on the patient and getting them used to it so they're not flinching If you're going to use this I recommend maybe Without worrying about running into the patient's eye. So we have Jocelyn here and we're examining Jocelyn's rightĬomes with this little cup here which allows you to go as close as you want In that lead you to have 20/20 vision you actually don't have to do anything If you have 20/20 vision or you have contacts Unless the patient's extremely nearsighted orįarsighted you usually can set it for yourself and not have to worry about it again. So I look at something about 10 to 15 feet away and make sure it's in 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.

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.
