PURPOSE OF USE

To observe and photograph the fundus through the pupil and document it.

OPERATION PRINCIPLE

The fundus of the patient's eye is illuminated by the infrared light emitted from the illumination optical system. The observation CCD camera built into the instrument receives the image and the image is indicated on the color LCD monitor allowing the operator to observe the fundus. After adjusting the photography position and focus, the visible light is emitted from the illumination optical system provided for photography by operating the photography switch of the instrument. The digital camera, which is connected to the instrument, receives the image and then the image is recorded in the memory card built into the digital camera or the connected image filing system or external recording device, which is a commercial product. The fundus of the patient's eye can also be illuminated, observed and photographed by the visible light after removing the IR filter from the illumination optical system. Moreover, it is possible to perform red-free observation and photography by inserting the RF filter into the illumination optical system.

Meaning of L

A and LB

• Spectrally weighted photochemical radiances LB and LA give a measure of the potential that exists for a beam of light to cause photochemical hazard to the retina. L eyes in which the crystalline lens is in place. L

A gives this measure either for eyes in which the

B gives the measure for

crystalline lens has been removed (aphakes) and has not been replaced by a UV-blocking lens or for eyes of very young children.

• The value stated for TRC-NW8 gives a measure of hazard potential when the instrument is operated at maximum intensity and maximum aperture. Values of L

B or LA over 80mW/ (cm

·sr)

are considered high for beams which wholly fill a dilated pupil.

• Because prolonged intense light exposure can damage the retina, the use of the device for ocular examination should not be unnecessarily prolonged, and the brightness setting should not exceed what is needed to provide clear visualization of the target structures. This device should be used with filter that eliminate UV radiation (<400 nm) and, whenever possible, filters that eliminate short-wavelength blue light (<420 nm).

• The retinal exposure dose for a photochemical hazard is a product of the radiance and the exposure time. If the value of radiance were reduced in half, twice the time would be needed to reach the maximum exposure limit.

• While no acute optical radiation hazards have been identified for fundus cameras, it is recommended that the intensity of light directed into the patient's eye be limited to the minimum level which is necessary for diagnosis. Infants, aphakes and persons with diseased eyes will be at greater risk. The risk may also be increased if the person being examined has had any exposure with the same instrument or any other opthalmic instrument using a visible light source during the previous 24 hours.This will apply particularly if the eye has been exposed to retinal photography.
