Fast and precise perimetry

Fast and precise perimetry at your fingertips.

Automated Perimeter PTS 920 is a modern diagnostic  instrument for precise and fast testing of field of vision. Beside standard  perimetry testing techniques it implements all modern approaches which save time  and deliver cutting edge precision and reliability. Intuitive software with  powerful networking and EMR integration, combined with maintenance free and  reliable hardware creates the best tool for visual field testing.

PTS 920 contains complete set of standard  perimetry tests. Variety of threshold algorithms and screening techniques to  choose from, always give the right answer for specific medical case. Thanks to  wide range of testing point maps organized in radial patterns, stimuli are  denser in the center and help to find central scotomas (contrary to popular 30-3  and 24-2). With PTS 920, all special tests like Binocular Driver’s Test, Flicker  perimetry and Blue on Yellow* test become fast and easy.

Advanced strategy which utilizes a  special testing algorithm, allows quicker examination without loss in result  resolution. Radial equivalent of 24-2 and 30-2 field can be tested in less than  3 and 4 minutes respectively. This fast and repeatable procedure provides you  with more detailed information than screening strategies in comparable duration.  Shorter testing time directly translates not only to higher patient throughput  but also to patient comfort and test result  reliability.   

PTS 920 features high resolution camera for precise  monitoring of patients’ compliance.  Blink control mechanism assures that no  stimuli are omitted due to normal blinking. Expositions interrupted by blink are  repeated, and test is held until the eye is opened again. Constant eye tracking  mechanism analyses pupil movement and assures supreme reliability of test  results.
PTS 920 contains  rich library of predefined test fields and programs. Intuitive software provides  means of creating custom programs and test point patterns. Custom test settings  can be stored and accessed with one mouse click. This helps to save valuable  staff time and assures optimum patient flow with minimal effort. Follow-up tests  can be performed with ease, by simple selection of base examination and starting  the new one. Testing of difficult patients is made easy with PTS 920. Partial  test results of not completed test can be stored in patient’s record and  continued in the future.

PTS 920  built-in networking features assure that all the data can be accessed from  anywhere within your network. Networked reviewing stations can display and  review data updated in real-time by examination host machine. With networking  facilities, PTS 920 provides optimum conditions for undelayed practice  workflow.

PTS 920 with its out of the  box DICOM support, allows seamless integration of perimeter into your DICOM  environment. Storing visual field reports on the DICOM image server is made easy  with PTS 920. Thanks to DICOM Modality Worklist support  operator comfort  is  increased and the risk of transcription errors eliminated. Besides DICOM, PTS  920 supports also GDT and custom EMR’s based on text file interface. This allows  your practice to be up to date with today’s information  technology.

PTS 920 features  a user friendly voice guide module. Voice messages assist operator and patient  during the examination and help to efficiently complete the test procedure.  Thanks to this remarkable feature, operator always knows when the special  attention is needed and can eliminate risk of results variability problem with  difficult patients.

PTS 920  offers complete palette of analysis tools for quick and thorough assessment of  visual fields. Advanced analysis algorithms supported by normative and  statistical data help in comprehensive identification of defects. Comparison and  progression module available in standard package help to gain advantage in long  term results evaluation.
