Authorized representative in the European Community Global Trade Item Number Warnings and Cautions 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: To minimize lamp housing temperatures, ontime 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.
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.
Set-up Instructions Attaching the Pan Optic Ophthalmoscope head to a Welch Allyn Power Source Align cutouts in the PanOptic Ophthalmoscope base with lugs on power source. (The PanOptic Ophthalmoscope fits all 3.5v Welch Allyn power sources.) Push in slightly and turn 90 degrees. TURN HANDLE COUNTERCLOCKWISE Attaching the Patient Eyecup to PanOptic WARNING: Use only PanOptic Patient Eyecups with this product. Insert eyecup into the patient’s side of the instrument.
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 on page 5, 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). 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.) 4. Start with the small aperture (green line position on the aperture dial).
5. Turn the scope on (using any Welch Allyn 3.5V power source). Adjust light intensity rheostat to desired position. You are now ready to begin the examination: 6. Examiner should be positioned approximately 15 degrees to the temporal side of the patient. 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. 9.
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). 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.
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.
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.
Apertures and Filters There is a wide range of practical apertures and filters to select from: small spot, large spot, micro spot, slit aperture, red-free filter, cobalt blue filter (optional), and half-moon aperture (optional). 1. Small Aperture: Provides easy view of the fundus through an undilated pupil. Always start the examination with this aperture and proceed to micro aperture if pupil is particularly small and/or sensitive to light.
used to help distinguish veins from arteries; veins stay relatively blue, but oxygenated arterial blood makes arteries appear blacker. This greater contrast makes differentiation easier for the examiner. 6. Cobalt Blue Filter (Model 11820 only): In conjunction with fluorescein dye applied topically to the cornea and an add-on magnifying lens (included), this filter is helpful in detecting corneal abrasions and foreign bodies. In this way, it can be used as a surrogate to a Woods Light. 7.
The Eye In addition to examination of the fundus, the PanOptic Ophthalmoscope is a useful diagnostic aid in studying other ocular structures. The light beam can be used to illuminate the cornea and the iris for detecting foreign bodies in the cornea and irregularities of the pupil. The practitioner can also easily detect lens opacities by looking at the pupil through an add-on corneal viewing lens.
Lamp Replacement Instructions WARNING: Lamps may be hot. Lamp should be allowed to cool before removal. Use only Welch Allyn model 03800-U or 03800-LED lamps with this product. 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.
Repairs Repairs should be performed at the factory. Cleaning and Disinfection Lenses: PanOptic is a precision optical instrument. Do not use any solvent-based cleaners on the lenses. Use only a clean optical grade cloth to clean the lenses. Housing: Wipe the PanOptic housing with an appropriate health care low- or intermediate-level cleaner/disinfecting wipe that incorporates either a 1:10 sodium hypochlorite (bleach) solution or isopropyl alcohol as the active disinfection ingredient.
