*Please order separately DEH 506 for mains operation or DEH 504 for power supply independent use*Modern vestibular diagnostics require a high degree of precision when looking for spontaneous or provoked nystagmus. In many cases, the only way of making a correct diagnosis was to perform a technically complex electronystagmography (ENG). The new nystagmus glasses by De. Blessing represent a user-friendly alternative. With these new goggles, nystagmus intensity and amplitude achieve 80% - 99% of ENG values. Dr. Blessing’s new Nystagmus Goggles are illuminated indirectly so as to not trigger light reflexes that could have the undesired, nystagmus-inhibiting effect of visual fixation in the patient. As shielding of the light bulbs means that light does not fall directly onto the patient’s eyes, no PURKINJE vein image occurs, the movement of which could trigger arbitrary “illuminated goggles nystagmus”. As such, we avoid false positive nystagmus results. The actual examination using these goggles takes place in a dark or a heavily dimmed room. The illumination of the inside of the goggles causes the patient to lose visual contact with his/her surroundings (preventing nystagmus-inhibiting visual fixation). At the same time, it is especially easy to observe the patient’s brightly illuminated eyes using magnifying lenses. This means it is often possible to detect immediately, just by looking at the patient, pathological nystagmus processes that would be impossible or difficult to detect, even when looking sideways- The Nystagmus Spectacle Type 521 can be operated with max. 4 Volt- with fixed connection wire 1.5 m, Clip headband

This model is cordless and does not require an electrical connection. The nystagmus goggles are powered by an adjustable battery grip that is installed facing upwards and is designed to accommodate three 1.5 volt C LR14/AM-2 batteries (baby cells). (Batteries not included!).

The Type 803 model is used on a mobile basis for short-term examinations. The actual examination using these goggles takes place in a dark or a heavily dimmed room. The illumination of the inside of the goggles causes the patient to lose visual contact with his/her surroundings(preventing nystagmus-inhibiting visual fixation). These new LED Nystagmus spectacles are illuminated by diodes arranged in a circle behind a light panel that generate a diffuse, brightness-adjustable light, without the possibility of fixable points of light affecting the result of the examination. With our new LED battery Nystagmus spectacles, the timer feature makes it easier to monitor impulses within a specific time period (30, 60, or 90 seconds).? In the battery version of the LED Nystagmus spectacles, the lighting turns itself off one minute after the timer has elapsed and turns itself on automatically when the LED Nystagmus spectacles are put on again. This power-saving feature in addition to a “Low Battery” display are intended to guarantee the constant usability of the LED Nystagmus spectacles. The automatic on/off switch can be disabled if not required.- LED lighting- Diffuse illumination- Stepless control of brightness- Timer Function- Automatic on/off switch- Tempered glasses

The clip headband lets you fit the nystagmus goggles securely in front of the patient’s eyes. This in turn makes it easy to look for provoked nystagmus, e.g. by shaking the patient’s head or by performing swivel-chair or postural examinations. Slightly squeeze the clip headband to remove it from the slots of the nystagmus spectacles.

In many cases, the only way of making a correct diagnosis was to perform a technically complex electronystagmography (ENG). The new Nystagmus spectacles by Prof. Frenzel is especially suitable for short-term examinations. Thanks to the new bajonet connection and the different connection wires, the Nystagmus Spectacle can be quickly transformed into spectacle that are suitable for various examination e.g. for storing or examinations on swivel-chairs. By using the corresponding components the Nystagmus Spectacle come up to the individual expectations of the doctor.
