Welch Allyn 11820-CE Panoptic Head with Cobalt-Blue Filter and Corneal Viewing Lens
PanOptic Ophthalmoscope with Cobalt-Blue Filter and Corneal Viewing Lens
Welch Allyn introduces the PanOptic™ Ophthalmoscope, a revolutionary new concept for visualizing the fundus. Developed by Welch Allyn® the originator of the world's first hand-held direct illuminating opthalmoscope, the PanOptic™ incorporates an innovative and patented new optical design called Axial PointSource™ Optics. This enabling technology makes it easier to enter small pupils and provides a dramatically wider, more panoramic view of the fundus that's 5X larger than ever before achieved with a standard opthalmoscope in an undilated eye.
How it Works
Transparency of the cornea, lens and vitreous humour 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.
* New Halogen HPX™ lamp provides bright, white light.
* Greater working distance improves the comfort of both examiner and patient.
* Works with all existing Welch Allyn 3.5V power sources (battery handle or wall transformer), saving additional investment.
* The patient eyecup establishes and maintains proper viewing distance, provides stabilization for the view, is a pivoting point for leverage in panning around the retina, occludes ambient light, and helps with orientation.
* The dynamic focusing wheel adjusts the focus in a continuous, smooth action for more precise control and the optimum view with a focusing range of -20 to +20 diopters.
* The aperture dial has micro, small, and large spot sizes, a slit aperture, red-free filter, and cobalt blue filter with add-on corneal magnifying lens (Model 11820 only).
* The ergonomic design of the built-in, soft grip handle provides maximum comfort, balance and access to controls
Patented new Axial PointSource™ Optics.
Illumination system converges the light to a point at the cornea, allowing easy entry into small, undilated pupils. The illumination pathway then diverges to the retina, illuminating a very wide area of the fundus. Viewing system enables the operator to view the illuminated area on virtually the same axis, creating the widest field-of-view attainable. Provides a 5-times larger view of the fundus than ever before achieved with a standard ophthalmoscope in an undilated eye.
* Enables a 25-degree field-of-view vs. the standard 5-degree field-of-view.
* Increases magnification by 26% over a standard scope.
* Patented Glare Extinguishment System prevents interference from unwanted glare and reflections.
