Country-specific information and labels
Indication for use The VISUCAM Digital Fundus Camera is suitable for photographing, displaying and storing data relating to the retina and surrounding parts of the eye being examined under mydriatic and non-mydriatic conditions. These photographs assist with the diagnosis and follow-up of eye diseases, which can be visually monitored and photographically documented.
CAUTION - GENERAL HAZARDS Use of mydriatics may occasionally result in side effects which may include life or sight-threatening reactions such as acute glaucoma, cardiac arrhythmias, increased intraocular pressure, and sudden high blood pressure. The lowest possible dose for dilation of the pupil should be used. Please also observe manufacturer's specifications. CAUTION - RISK OF OPERATING ERRORS Do not use the VISUCAM in patients with the following conditions: • Unable to follow the instructions of the user • Unable to sit upright in front of the instrument • Forehead or chin injuries that prevent the head from being supported on the head/chin rest Allow for serious restrictions in the use of the VISUCAM for the following patient groups: • Complete or partial coverage of the cornea caused by palpebral fissure which is closed or too small • Unable to steadily fixate the fixation lights with the eye under examination (e.g. in the case of nystagmus, tremor, Parkinson's disease, extremely poor visual acuity, lack of concentration) • Non-foreseeable influence of wearing contact lenses (remove contact lenses before exposure) • Patients with a small pupil

Performance specifications
mÉêÑçêã~åÅÉ=ëéÉÅáÑáÅ~íáçåë= Functional description The VISUCAM allows the fundus of the eye to be viewed and documented with the pupil in a naturally or medicinally-induced dilated state. Easy-to-use camera operation ensures quick results. It is particularly suitable for routine use and screening. The fundus is evaluated on the basis of a flash photograph. Image capture and display is fully digital. The VISUCAM employs the ophthalmoscope principle of the modern fundus camera and images the fundus of the eye at a field angle of 45° or 30°. The instrument operates in non-contact mode. Non-mydriatic operation is based on positioning and focusing of the camera using infrared light. This means that the use of pupil-dilating drops is not necessarily required. This does, however, require a naturally dilated pupil, such as is achieved in a darkened room. The non-mydriatic technique is not suitable for fluorescein angiography (VISUCAM 500 only); in this case medicinally-induced dilation is required. Infrared diodes are used as a light source for setting up the camera. The working distance is set up using two working distance dots and the fundus brought into focus using a pair of coincident lines. A flashbulb is used to record images. The VISUCAM 200 supports capture modes Color, G (green), R (red) and B (blue). VISUCAM 500 additionally supports capture modes FA (fluorescein angiography) and optionally AutoFluo (auto-fluorescence) and ICGA (indocyanine green angiography). The settings are controlled via the live setup image displayed on the monitor. After image capture has been triggered, the image is displayed on the monitor in place of the live set-up image and saved automatically. The digital image sensor has a resolution of five megapixels. The VISUCAM includes an intuitive software interface for databasesupported patient and image data administration. Images can be displayed, printed and exported and patient data created and adapted simply at any time. The software also includes a basic image optimization feature for printouts.
000000-1781-493_GA_GB_230710
Performance specifications
As for standard commercial digital cameras, the VISUCAM is only able to store images for a limited time period, depending on the limited hard disk capacity. Images can be stored long term using an external archiving system (e.g. VISUPAC or FORUM systems) or by retaining the printouts. Image data can be exported in BMP, JPEG, TIFF or DICOM formats. The DICOM format additionally permits the transfer of patient-relevant information. To export and copy data to another computer system, a network connection is recommended. The integrated DVD/CD burner allows data to be transferred to DVD or CD. A USB flash drive is also available.
Service life WARNING - GENERAL HAZARDS The development, production and maintenance of this device, together with associated risks, are based on an expected service life of eight years, assuming that the device is serviced at the specified intervals. Modifications to the product or failure to follow the manufacturer’s instructions may substantially reduce the expected service life and significantly increase the risks associated with the use of this device. It is the responsibility of the institution operating this product to follow the manufacturer’s instructions and to decide on the risk/benefit ratio upon expiration of the expected service life or maintenance and inspection intervals specified by the manufacturer.

The device should be set up so that the power cable can be disconnected from the power supply quickly and easily without any tools. WARNING - RISK OF ELECTRIC SHOCK Additional extension cables or portable multiple sockets may not be used. The electrical installation must conform to IEC 60364-7-710 or the applicable national regulations. This includes the existence of a ground fault circuit interrupter (GFCI). To avert the risk of an electric shock this device may only be connected to a power supply with a protective earth conductor. Ensure that the power supply plug is suitable and certified for the local connection. If the supplied power cable must be replaced, at least the following specifications must be adhered to: • Protective earth conductor resistance maximum 0.2 Ohm • Local certification of the power cable for connection to medical devices • Device plug C19 conforming to IEC 60320 • Cross-section at least 0.75 mm²/AWG 18 Hospital Grade design for specific countries (e.g. USA, Canada) (For cables > 2.5 m the cross-section must be increased to 1.5 mm²) WARNING - FIRE HAZARD The device is not suitable for operation in explosion risk areas (e.g. combustible mixture of anaesthetic, cleaning or disinfecting agents with air, oxygen or nitrous oxide). The electrical installation must conform to IEC 60364-7-710. The data concerning power consumption on the type plate must be taken into account in the selection of overcurrent protection. The device should be switched off and unplugged from the power supply before replacing the fuse.
