Welch Allyn Panoptic Ophthalmoscope - Quick Reference Guide - Manual

Symbols
Warnings and Cautions
The
PanOptic
™ Ophthalmoscope
Transparency of the cornea, lens and vitreous humor permits the practitioner to directly
view arteries, veins, and the optic nerve of the retina.
Direct observation of the structures of the fundus through a PanOptic Ophthalmoscope
may show disease of the eye itself or may reveal abnormalities indicative of disease
elsewhere in the body. Among the most important of these are vascular changes due to
diabetes or hypertension and swelling of the optic nerve head due to papilledema or
optic neuritis. In this sense, the eye serves as a window through which many valuable
clinical evaluations may be made.
When a preliminary diagnosis of an imminently dangerous eye condition, such as acute
(angle-closure) glaucoma or retinal detachment, is made by the examiner, prompt
referral to an eye specialist may prevent irreversible damage. Or, when distressing but
less urgent conditions, such as visual impairment due to cataract or vitreous floaters,
are recognized, the patient can be reassured and referred.
Set-up Instructions
Attaching the PanOptic
Ophthalmoscope head to a
Welch Allyn Power Source
Align cutouts in the PanOptic Ophthalmo-
scope base with lugs on power source.
(The PanOptic Ophthalmoscope fits all 3.5v
Welch Allyn power sources.) Push in
slightly and turn 90 degrees.
Attaching the Patient Eyecup to PanOptic
Insert eyecup into the patient’s side of the
instrument. Push and twist in one motion until
you feel the two “lock” together.
See Accessory and Replacement Parts List to
reorder new PanOptic Patient Eyecups.
Attaching Corneal Viewing Lens
to
PanOptic (Model 11820 only)
Insert Corneal Viewing Lens into patient’s side of the instrument. Push and twist in one
motion until you feel the two “lock” together as shown, except replacing Patient Eyecup
with the Corneal Viewing Lens. Verify that the line on the lens housing is aligned with
the top seam of the PanOptic instrument.
Conducting an Examination with the
PanOptic
Ophthalmoscope
1. To examine the right eye, stand or sit to the patient’s right side.
2. Remove Spectacles (preferred, but not required) (A).
3. Look through the scope (from the doctor’s side) with your thumb on the focusing
wheel. Focus the scope on an object roughly 15 feet away. (This procedure will
make any adjustments for your own eye’s corrective needs. (B))
4. Start with the small aperture (green line position on the aperture dial). (C)
5. Turn the scope on (using any Welch Allyn 3.5V power source). Adjust light
intensity rheostat to desired position. (D)
You are now ready to begin the examination:
6. Examiner should be positioned approximately 15 degrees to the temporal side of
the patient. (E)
7. Instruct the patient to look straight ahead at a distant object.
8. Begin from about 6 inches away, looking through the scope and shining the light
at the patient’s eye while looking for the red retinal reflex. (F)
9. Rest your left hand on the patient’s forehead. (optional)
10. Slowly follow the red reflex toward the patient and into the pupil. Get as close as
possible for the optimum view (the eyecup should contact the patient’s brow). (G)
11. Once you have a stable view of the fundus rotate the focusing wheel until you
have a crisp view of the optic disc and the vessels surrounding it.
Note: For the largest view, compress the eyecup halfway against the patient’s
brow. This enables the user to view the entire optic disc plus many
surrounding vessels (about 25° field of view) at one time. (H)
12. Examine the optic disc for clarity of outline, color, elevation and condition of the
vessels. Follow each vessel as far to the periphery as you can. To locate the
macula, focus on the disc, then move the light approximately one (1) disc diameter
temporally. You may also have the patient look at the light of the ophthalmoscope,
which will automatically place the macula in full view. Examine for abnormalities
in the macular area. The red-free filter facilitates viewing of the center of the
macula, or the fovea.(I)
13. To examine the extreme periphery instruct the patient to:
A look up for examination of the superior retina
B look down for examination of the inferior retina
C look temporally for examination of the temporal retina
D look nasally for examination of the nasal retina.
This routine will reveal almost any abnormality that occurs in the fundus.
14. To examine the left eye, repeat the procedure outlined above. However, unlike
traditional ophthalmoscopy, a unique feature of PanOptic is that the examiner
does not have to switch to his/her left eye. The practitioner can use either eye to
examine either patient eye because of the greater working distance between
patient and practitioner. This permits those who are strongly dominant in one eye
to always use that eye in the fundus exam. (J)

WARNING: The light emitted from the ophthalmoscope is potentially
hazardous. The longer the duration of exposure, the greater the risk of ocular
damage. Exposure to light from this instrument, when operated at maximum
intensity, will exceed the safety guideline after 13 minutes when lit with a
LED lamp (blue base). Exposure times are cumulative for a 24-hour period.
WARNING: When using Halogen illumination, no acute optical radiation
hazards are identified. However, Welch Allyn recommends limiting the
intensity of the light directed into the patient’s eye to the minimum level that
is necessary for diagnosis. Infants, aphakes, and persons with diseased eyes
are at a greater risk. The risk is also increased if the examined person has
had any exposure with the same instrument or any other ophthalmic
instrument using a visible light source within the previous 24 hours. This will
apply particularly if the eye has had exposure to retinal photography. The
intended use of this device is for routine ophthalmic exams on the order of
typically less than 60 seconds per eye. Although there is a benefit versus risk
factor in any medical procedure, these more complicated exams should not
exceed a three minute exam time in 24 hours. Significant use of this device
beyond its intended use is not recommended; it may cause harm to the eyes.
WARNING: To minimize lamp housing temperatures, on-time should not
exceed 2 minutes with off-time not less than 10 minutes.
WARNING: Use only PanOptic Patient Eyecups with this product.
WARNING: Rx only (for professional use).
WARNING: Lamps may be hot. Lamp should be allowed to cool before
removal.
WARNING: Equipment not suitable for use in the presence of a flammable
anesthetic.
CAUTION: Halogen lamps are pressurized to provide maximum efficiency
and illumination. Mistreatment may cause shattering. Protect lamp surface
against abrasion and scratches. Verify power is off when replacing lamp.
Dispose of lamp with care.
