| Autofluorescence |
| This diagnostic procedure is new to fundus camera imaging. It allows imaging of the ocular fundus
relying on the presence of lipofuscin in the retina pigment epithelium (RPE). The TRC-50DX features
the capability of adding the additional exciter and barrier filters for use with digital monochromatic
CCD cameras. Auto Fluorescence is a promising addition to other standard fundus
camera procedures. Auto Fluorescence is optional and requires an upgrade kit.
|
| |
| Digital Transfer |
| The Topcon TRC-50DX features several unique capabilities which
enhance its use, increase convenience and reduce errors when
coupled with IMAGEnet™. The angle selection [20° – 35° – 50° ]
as well as Left Eye – Right Eye transfer data directly to the patient
file automatically during image capture.
|
| |
| Stereo Image Capability |
|
Stereo imaging is simple and repeatable
using the stereo locking lever. Two images
representing stereo pairs are captured
quickly and easily every time.
|
| |
| Optimized Flash-Intensity Control |
|
The flash intensity control has 21
levels and can be used in full or half
steps. Sensitive membrane buttons
permit total control of image brightness
and are illuminated for use in
subdued light.
|
| |
| Working Distance Dots |
|
Green alignment dots provide easy
confirmation of working distance
of the objective lens to the ocular
region. These alignment dots are
helpful for pre-injection positioning
in fluorescein angiography (FA), redfree,
and color fundus photography.
|
| |
| Immediate Access to Controls |
|
Designed with user convenience
in mind, the TRC-50DX features
an illuminated touch panel control
that allows the operator to
change camera settings with a
light touch. All adjustments are
at the technician’s fingertips.
|
| |
| Small Pupil Mode |
|
The "SMALL PUPIL" mode
permits imaging through pupils
as small as 4.5mm, which is
useful when the patient is not
well dilated due to medication
and other physiological reasons.
|
| |
| Small Aperture Adjustment |
|
The “SMALL” setting produces
a sharper and easier to focus
image because of enhanced
depth-of-field.
|
| |
| High and Wide Eyepiece Viewing |
|
The eyepiece of the TRC-50DX is designed for high and
wide eye distance viewing making alignment and focusing
fast, easy and comfortable for the technician.
