 Is the PocketScope Diagnostic Set popular with students?
Actually, fewer than 10% of all students purchase a PocketScope set. Many students tell us that the 3.5 V sets are easier to learn on. The 3.5 V sets provide more light, which is key to getting a good view of the eye and the ear.

Small aperture: Provides an excellent view of the fundus through an undilated pupil. *
Large aperture: Standard aperture for dilated pupil and general examination of the eye. *
Fixation aperture: Features graduated crosshairs for measuring eccentric fixation or locating lesions. *
Slit: Used to determine levels of lesions and tumors. *
Cobalt filter: Used with fluorescein dye to view small lesions, abrasions, and foreign objects on the cornea *
Half-moon aperture: Provides combination of depth perception and field of view
What is a diagnostic set?
A diagnostic set consists of an ophthalmoscope for examining the eye, an otoscope for examining the tympanic membrane and external ear canal, and a battery handle to power these instruments. Welch Allyn are the market leading in providing diagnostic sets. There are a large number of different sets available from Welch Allyn Australia.
How does the Coaxial Vision System help when performing a fundus exam?
When viewing the fundus it is extremely important that the light beam from the ophthalmoscope and your viewing angle are in close proximity. The path your eye follows through the patient’s eye to the fundus is extremely narrow; therefore, the most efficient method of viewing the fundus is to keep the ophthalmoscope’s light beam and your viewing path in near coincidence.
In all other viewing systems, the viewer looks over the top of the mirror from a steeper angle. The visual axis and axis of illumination do not coincide, so parallax and resultant shadowing are increased.
How does the Coaxial Vision System of the conventional ophthalmoscope help when performing a fundus exam?
When viewing the fundus it is extremely important that the light beam from the ophthalmoscope and your viewing angle area are in close proximity. The path your eye follows through the patient's eye to the fundus is extremely narrow; therefore, the most efficient method of viewing the fundus is to keep the ophthalmoscope's light beam and your vision line in synch as much as possible.
How does the Welch Allyn otoscope convert to a throat or nasal illuminator?
Hold the throat illuminator's collar stationary and twist the otoscope section loose. Keep the otoscope section stationary and turn the power handle until the otoscope section is removed. The throat illuminator is now ready to use. The nasal illuminator attachment snaps easily onto the power handle for a full view of the nasal passages.
How durable is the Welch Allyn otoscope? Extremely durable. Check out the busiest hospital and physician exam rooms to see what otoscope they use when durability counts. Welch Allyn otoscopes are engineered and manufactured for precision and longevity:
· They are manufactured with metal and high-impact ABS material.
· They have reinforced, flush-mounted fiber optics.
· They will maintain their shape, even if dropped.
· A metal, flush mounted insufflator port is included in the design.
If I am currently a student, but will graduate soon will I still be able to get support and service?
Yes, certainly! Service and support is an aspect we take pride in. If you have purchased a product be it Welch Allyn or any other brand from Medshop and you require service and/or support at any point in your study or career be sure to contact Medshop first.
Is glare a problem during ophthalmoscopy, and if it is, how can it be dealt with?
Excessive glare can result when light reflects back from a patient's eye because of the shape of a person's cornea, their internal limiting membrane, and/or the presence of an intra-ocula lens. Welch Allyn, however, is the only manufacturer that offers a patented crossed-linear polarizing filter to eliminate 99% of unwanted reflections.
What is a red-free filter?
The red-free filter excludes red rays from the examination field for easy identification of veins, arteries, and nerve fibers. The red-free filter can be used with any of the six apertures.
What is an ophthalmoscope and what is used for?
The ophthalmoscope allows you to view the back of the eye, commonly called the fundus. This is where nerves and blood vessels converge, and it is the only place these structures can be seen without surgery. A good view of the fundus not only helps you assess the health of the patient's eye, but it will also tell you a lot about his or her overall health. An ophthalmoscope can detect early signs of diabetes, hypertension, and some neurological problems.
What is an otoscope used for?
The otoscope is used to view the ear's tympanic membrane and external canal to diagnose outer- and middle-ear pathologies.
