The ARIS Automated Retinal Imaging System is a patented,
fully automated system that images the inside back surface of the eye
(the fundus), that includes the retina, without requiring a highly trained
specialist to operate.
ARIS received FDA clearance to market in November of 2002, and
Commercial production and shipment began in 2004.
Key Advantages of the ARIS™
The ARIS automates essentially the entire procedure for acquiring
high-quality retinal images. At the start of the imaging procedure, the
operator sees an image of the patient's pupil on the monitor and, using
a mouse, moves the image until it is roughly centered. From that point
on, the ARIS illuminates, then automatically completes and maintains
alignment and focus, adjusts the light exposure and acquires a pair of
stereo images. Typically it requires less than 15 seconds to obtain infrared,
red-free and color images
all in stereo.
With the ARIS, patient comfort is dramatically increased. There
is no discomfort due to high intensity light flashes during imaging. The
ARIS uses infrared illumination for the pupil focus procedure and
for monochrome imaging. For color imaging, colored light is used, but
at much lower intensity than in existing fundus cameras. For a large percentage
of the patient population, no dilation of pupils is required for acquiring
images of a single field on the retina. For multiple field imaging, most
clinicians will dilate the pupils as a matter of convenience and time.
A single color, stereo-pair imaging procedure typically takes about 15
seconds to complete. A standardized diabetic retinopathy imaging procedure
seven
field, stereo images
a total of twenty-eight images
takes about
5 minutes with the ARIS, compared with about 30 minutes for a competitive
fundus camera.
Many ophthalmologists and optometrists presently do not do fundus
photography because existing fundus cameras are time-consuming and difficult
to operate. The ARIS allows them to produce retinal images quickly
and easily using existing office personnel, thereby adding significantly
to revenue. For those eye care professionals now doing retinal photography,
the ARIS provides a dramatic increase in patient throughput while
reducing operating costs.
Visual Pathways received FDA 510 (K) clearance to market ARIS
in November, 2002.
U.S. patent 6,296,358 covering the ARIS technology was issued
October 2, 2001, with additional U.S. and international patents pending.

Buried Drusen



We have surveyed vision care clinicians, fundus
photographers and technicians because we wanted to hear your thoughts
on the ideal fundus camera. You told us these things were
important: Automation of target selection and image acquisition; auto-pupil
alignment and tracking; auto-stereo image acquisition and registration.
We heard you clearly.
Visual Pathways, Inc. is pleased to introduce
the ARIS (Automated Retinal Imaging System), the worlds first
truly automated fundus camera. With the ARIS brand, were bringing
together science and technology to bring you automated imaging procedures
that both the operator and patient will appreciate.
