The Zeiss Visucam Lite is indeed less capable of its big brother (Visucam Pro) but I think we can all agree that ‘Lite’ is a suffix designated for beverages without calories. A suffix that should not be used for medical devices, especially ones still capable of diagnosing diseases- but nevertheless the name is not important in this case. The Visucam Lite is undoubtedly slimmer, lighter, and sleeker than the Pro model; also lacking in some software functions and absent of auto-tracking/auto-focussing. Despite this, I’m not sure the Visucam is deserving of its ‘little sister’ depiction. Upon using the Visucam Lite, you’ll notice that its relation runs deep and any major contrasts are hard to find. The software is slightly more dated than that of the current Pro model– something you’ll notice but not particularly judge, and the mandate for operator interface to properly align and focus requires some basic training, but all forgivable given the reduction in price.
OUR TAKE: It’s the four cylinder turbo Volkswagon that starts every time and takes you where you need to go, but fails to pin your head against the seat.
A true all-rounder: VISUCAM Lite with a field angle of 45° for the standard wide view.
• colored fundus images
• fluorescein angiography
• red-free, blue and red photos • stereo photos
Photos of anterior segments (iris, sclera and injuries near the eye) in addition to video clips.
The concept incorporated in VISUCAM Lite will also impress patients. All the images captured are immediately available. Decisions about further therapy can be made at once. Referrals to a hospital for further diagnosis, to a photographer or to another ophthalmologist are unnecessary. The ophthalmologist’s office has the patient’s complete image file at its disposal. This forms the basis for optimum follow up and legal cover.
The minimum light exposure made possible by the low amount of light required for setting and image capture guarantees a really gentle approach to diagnosis. No flash is required. For patients who are particularly sensitive to light, infrared viewing light can be used. Full patient co- operation during the procedure is ensured. The IR illumination is the basis of possible non-mydriatic photography. This is a decisive benefit when the administering of mydria- tic drugs is problematic (lack of time, drivers, glaucoma).
Simple patient and image management and an easy-to-understand capture mode form the basis of a fast and efficient patient through put. A new tool is available for analysis. It enables:
• Fast checking of all images
• Comparison between old and new images • image editing and ZOOM
• Image arrangement for printout.
VISUCAM Lite can be upgraded with the professional VISUPAC software for external computers. After the two systems have been networked, all the functions of VISUPAC are available, particularly those for measurement and photomontage.
All data are present in a digital form and are available at all times. Within a network the export of image data or the import of patient data can be performed automatically. DICOM allows all the image information to be read by external users (e.g. right/left eye, pixel size). In addition, an internal CD burner or an optional USB stick are availa- ble. USB printers can easily be connected.
The gentle approach to diagnosis without the use of a flash gun was of prime importance in the development of the system. A separating transformer guarantees maximum medical safety for all components. The automatic storage of each image prevents the loss of image data.
The VISUPAC System is recommended for professional data management and reliable, longterm archiving.
As the VISUCAM series cameras do not have a built-in external monitor, this instrument must be used in conjunction with the included 15″ monitor. The software on the VISUCAM Lite is built into the camera itself, therefore an external monitor does not require an external tower or other computer component.
Yes. The VISUCAM Lite can be networked via DICOM gateway (Ethernet), RS-232 serial cable, or via USB.
The VISUCAM Lite requires manual interface in order to properly align, focus, and capture the fundus.
