The 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.

Optopol Automated Perimeter PTS-920

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

Advanced strategy which utilises 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.   

The PTS 920 features high resolution camera for precise monitoring of patients’ compliance.  The Blink control mechanism assures that no stimuli are omitted due to normal blinking. Expositions interrupted by blinking are repeated, and tests are held until the eye is opened again. The constant eye tracking mechanism, analyses pupil movement and assures supreme reliability of test results.
PTS 920 contains a rich library of predefined test fields and programs. Intuitive software provides the means to create 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 a base examination and then beginning the new examination. Testing of difficult patients is also made easy with the 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 ensure 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 the examination host machine. With networking facilities the PTS 920 provides optimum conditions for undelayed practice workflow.

The 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. The DICOM Modality Worklist supports operator comfort and the risk of transcription errors is eliminated. Besides DICOM, the PTS 920 also supports GDT and custom EMR’s based on text file interface. This allows your practice to be up to date with today’s information technology.

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

The PTS 920 offers a complete palette of analysis tools, for a quick and thorough assessment of the visual fields. Advanced analysis algorithms supported by normative and statistical data, provide comprehensive identification of defects. The comparison and progression modules which are available in the standard package, offer the advantage of long term results and evaluation.
