PTS 1000
|
Automated Perimeter PTS
1000 is a modern diagnostic instrument for precise and fast testing of
field of vision. It offers static and kinetic stimuli with all Goldman
stimuli sizes and all stimuli colors used in perimetry. Wide range of
strategies and analysis tools combined with intuitive interface gives
you powerful diagnostic tool which handling you will enjoy. Built in
maps and possibility of creating own one gives possibility to examine
only these areas, which are necessary. With PTS1000 examination
doesn’t have to be tiring anymore.

FEATURES
- STANDARD
VISION TESTS - Depending on chosen test strategy, it enables to define
the sensitivity threshold of retina in a given area, as well as to make
a fast screening test. Accurate threshold, Intelligent fast threshold,
Screening and quick 3-zone can be selected according to needs and
patient’s condition.
- TIME SAVING - Fast threshold
strategy which utilizes special algorithm allows quicker examination
without loss in accuracy. Additional ‘Reduced Field’ and ‘Neurological
Field Reduction’ further shorten examination time.
- FLICKERING
TEST - The device also enables examination by means of flickering stimuli
for CFF (Critical Fusion Frequency) measurement. CFF is used as an
index of fatigue and it is clinically applied to neuro-ophthalmologic
disorders derived from optic nerve disorder especially, diagnosis and
evaluation of glaucoma.
- KINETIC TESTS - Thanks to kinetic
strategy it is possible to examine hardly cooperating patients with big
defects for which static examination is difficult to perform. 4 stimuli
colours, 5 Goldmann sizes, adjustable stimuli velocity, silent
operation, built in programs together with option of retesting
arbitrary vectors defined by user makes PTS1000 a top product for
kinetic perimetry.
- SWAP - It enables to use "blue on yellow"
(SWAP) examination method, red stimuli perimetry and green stimuli
perimetry. This method utilizes fact of Earlier loss of sensitivity to
colour based stimuli than to white-on-white stimuli based testing in
patients with ophthalmic disease.
- BINOCULAR
CAPABILITIES - Implemented BSV strategy allows examination of diplopy
areas. Testing of drivers is also possible thanks to included extendend
field, that enables testing field up to 80 degrees temporally and
Binocular Drivers Test.
- AUTODIAGNOSTIC - Built-in
autodiagnostic system will automatically detect any damages to device's
hardware and report it to the user.
RESULTS PRESENTATION
Test
result is presented as four easy-to-interpret graphic charts, two of
them are related to age norm and standard deviation. Results can be
analyzed in form of numerical maps of sensitivity in dB or in intuitive
dot scale. Also color presentation is possible for faster
identification of regions out of norm.
ANALYSIS TOOLS
Test
result printout contains also additional information useful for
interpretation, such as mean defect, pattern defect, Bebie curve,
defects progress analysis, and hill of vision slope.
RELIABILITY
Examination
reliability can be estimated on the basis of false negative and false
positive tests. Built-in digital camera allows eye-detection during
examination and during setting patient’s position, thanks to pupil
tracking system it allows a continuous automatic control of fixation. When patient losses fixation blind spot is examined and special attraction mechanism turned on. Well known Heijl-Krakau method allows tracking of a blind spot and monitoring of examination reliability.
