How to Use a Ophthalmoscope

Preparing your Equipment Check the battery Cover off Familiarize self with dials & levers, set all to

“0” Light should be bright, round, white Turn light down, dim

Preparing your patient Warn then about the light Position – sitting, looking on fixed spot over

your shoulder - slightly out (Be Specific)

Your Position Eye to Eye (Left to left, Right to Right) Try and keep your other eye open Begin at arm’s length by shining light into

the patient’s pupil. Continue to move forward until your

forehead rests on your thumb. The closer you are the wider your field of view.

Otoscopic Assessment Evaluate the

noninvolved ear first This practice provides a

basis for comparison AND prevents cross-contamination

Otoscopic Assessment Step 1:

Place your patient in a seated position with his/her head turned slightly downward and away from the ear to be examined

Otoscopic Assessment Step 1 (cont.):

the “puppy position” (puppies always cock their heads to the side when you talk to them)


Select the largest possible speculum that can be comfortably inserted into the ear


When inserted, the speculum should fit snugly in the outer third of the canal and rest against the tragus and anterior wall of the canal

Modified from Middle Ear Conditions. Anatomical Chart Co. Skokie, IL, 1999.


Choosing a speculum that is too small will cause movement within the canal

Excessive movement can cause discomfort for your patient



The otoscope should be stabilized by placing the ring and little finger resting on the patient’s cheek or temple

Otoscopic Assessment

Pencil Grip Hammer Grip


Pull the Pull the pinna pinna upward and upward and backward to backward to straighten straighten the canalthe canal



While maintaining traction on the pinna, place the speculum of the otoscope at, but not in the ear canal

Otoscopic Assessment Caution:

Never insert the otoscope blindly

Always“Watch your way in”

Otoscopic Assessment Tip:

If the patient experiences pain, reposition the canal by adjusting the angle and degree of traction on the pinna

Otoscopic Assessment Caution:

If the patient’s If the patient’s discomfort persists discomfort persists even after even after readjustment of the readjustment of the canal, halt the canal, halt the examination and examination and refer the patient to refer the patient to a physician.a physician.


Once the tympanic membrane comes into view, rotate the speculum to view as much of the membrane as possible
