Optopol PTS 900

 

Accuref 8001

 

Automated perimeter PTS 900 is a modern diagnostic instrument for precise and fast testing of field of vision by means of static stimuli. 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. Implemented BSV strategy allows examination of diplopy areas. Testing of drivers is also possible thanks to included extended field, that enables testing field up to 80 degrees temporally and Binocular Drivers Test. Built-in autodiagnostic functions will automatically detect any damages to deviceís hardware and report it to the user. Test result is presented as four easy-to-interpret graphic charts, two of them are related to age norm and standard field of vision. 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. 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 patientís position; thanks to auto-detection of pupil position - it allows a continuous automatic control of fixation. Automatically controlled chin-rest enables to set proper patientís position precisely and easily.
