Scopes

Otoscopes and Ophthalmoscopes The otoscope is used to exam the ears, nose, and mouth. The ophthalmoscope are used to examine the eyes, especially the retina. Eye and ear exams are difficult and require a lot of practice. You must practice with both these instruments to gain confidence in doing these exams.
The otoscope and the ophthalmoscope are located side-by-side. They must be in their proper positions or they will not function properly.
	To turn on both scopes, push the green side of the on/off switch.
Ophthalmoscope The ophthalmoscope is used to examine the retina of the eye or to evaluate the pupillary response.
	Otoscope. The otoscope is used to exam the ears, nose, and mouth. A disposable speculum is placed on the end of the otoscope.
Speculums Speculums are used on the otoscope during the ear and nose exams. Speculums come in a variety of sizes because ear canals and nostrils differ in size and shape.
	Putting a speculum on an otoscope. Place the proper size speculum on the tip of the otoscope, then turn the speculum until it is firmly on.
Adjusting brightness Brightness is adjusted on both the otoscope and the ophthalmoscope in the same way. Each scope has a black ring below the head.
	Rotating the ring to the left brightens the light, to the right dims the light.
