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. This
position is the “Home” position on the aperture dial and is denoted by
the green marking.
2. Large Aperture: Standard aperture for dilated pupil examination of the
eye.
3. Micro Spot Aperture: Allows easy entry in very small, undilated
pupils.
4. Slit Aperture (Models 11810, 11820 only): Helpful in determining
various elevations of lesions, particularly tumors and edematous discs.
5. Red-Free Filter (Model 11810, 11820 only): This filter excludes red
rays from the examination field: this is superior to ordinary light in
viewing slight alterations in vessels, minute retinal hemorrhages, ill-
defined exudates and obscure changes in the macula. The nerve fibers
become visible and the observer may note the disappearance of such
fibers, as in optic nerve atrophy. The background appears gray, the disc
appears white, the macula appears yellow, the fundus reflex is intense
and the vessels appear almost black. This filter is also 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. Half-Moon Aperture (11810 Only): Provides a combination of depth
perception and field-of view.
The Eye
In addition to examination of the fundus, the PanOptic Ophthalmoscope is a useful diag-
nostic 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. In the same manner, vitreous opacities can be detected by
having the patient look up and down, to the right and to the left. Any vitreous opacities
will be seen moving across the pupillary area as the eye changes position or comes
back to the primary position.

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 interme-
diate-level cleaner/disinfecting wipe that incorporates either a 1:10 sodium hypochlo-
rite (bleach) solution or isopropyl alcohol as the active disinfection ingredient. Follow
wipe manufacturer’s instructions for appropriate use, contact times and applicable
warnings and precautions.
Do not excessively saturate the PanOptic.
Do not immerse PanOptic in any solution.
Do not sterilize the PanOptic.
After disinfection, inspect the PanOptic for visible signs of deterioration. If evidence of
damage or deterioration is present, discontinue use and contact Welch Allyn or your
area representative.
Patient Eyecup: Wipe the Patient Eyecup with an appropriate health care low- or
intermediate-level cleaner/disinfecting wipe that incorporates isopropyl alcohol as the
active disinfection ingredient or soak in a glutaraldehyde-based solution. Follow prod-
uct manufacturer’s instructions for appropriate use, contact times and applicable warn-
ings and precautions.
Patient Eyecup can be autoclaved.
Do not use acetone based products or other harsh chemicals.
No other preventative maintenance is necessary for this product.
