Fundus Camera System
non-mydriatic fundus camera system enables practitioners to capture high-resolution,
digital images of the retina and posterior segment of the eye through the smallest
pupil size in the industry. In addition, the system captures high-resolution images
at 30°- and 45°-field angles, allowing for early documentation of such
conditions as diabetic retinopathy, AMD and glaucoma.
The ability to capture retinal images through undilated pupils
as small as 3.3 mm allows for quicker procedures of more patients, says Lon Dowell,
C.R.A., product manager and clinical specialist for retinal imaging at Carl Zeiss
Meditec, Inc. (CZM). The VISUCAMPRO NM uses
an efficient scientific grade sensor to capture images, which allows true retinal
color for a "what you see is what you get" image that is the same as what a doctor
would see upon an indirect ophthalmoscope exam. The system allows images to be viewed
in color, blue, red and red-free for diagnostic and documentation value.
The VISUCAMPRO NM
is an all-in-one unit; there is no need for external wires or peripheral cameras.
It is also unique in comparison to traditional fundus cameras in that there is no
operator eyepiece. Images are viewed real-time on a 17-inch flat panel monitor,
which can be rotated for patient education. With its potential for stereo images
and standardized field angles, the image quality serves as a solution for cases
that may require in-depth study. Visual overview and assessment are possible at
all times in every phase of the exam.
Pictures may be exported in a number of file formats. An ink-jet
printer, included with the system, is used to print out the images. The VISUCAMPRO
NM is networkable out-of-the-box and the industrial-grade
internal digital sensor requires no maintenance, keeping the optical path free of
dust or other artifacts.
For more advanced capabilities, the VISUCAMPRO
NM can be networked with CZM's VISUPAC digital imaging
and archive management application. The VISUPAC software manages image display,
editing, archiving and data export.
Derek Kuhl, M.D., Ph.D, of The Retina Center, Bryan, Texas says
that the VISUCAMPRO NM is
both easy to learn and fast to use. "It's a device that really lets anyone in the
clinic take excellent pictures," says Dr. Kuhl. "It requires almost no training
to take good non-mydriatic pictures and the response time in viewing the picture
is excellent. We can give patient feedback immediately." Dr. Kuhl says that the
system's imaging quality and color rendering are much better than their previous
Another nice feature, notes Dr. Kuhl, is that the system is easily
networkable. "With this system, we take a picture and it is stored on the hard drive
and saved at another location for automatic backup. The system does not require
a huge infrastructure and took us 10 minutes to get up and going network wise."
Stephen Fox, M.D., of Fox Eye Surgeons, Lima, Ohio, uses the VISUCAMPRO
NM primarily for stereo disk photos. "This camera
doesn't wash out the nerve for disk photos this is a very helpful feature
for capturing the optic nerve head," says Dr. Fox. "The camera either does it just
right the first time or with minimal adjustment to the flash."
Dr. Fox says the camera is very simple to use. "There are simply
two focusing dots and once they are clear you get a good photo."
