Both Rodenstock Perimeters are developed to meet the needs of today's clinical practitioner. The Perimat offers high-end performance matching the latest standards in modern perimetry. The Peristat is designed to fulfill all standard tests in return for a modest investment.

Modern Eye Tracking System
Both Systems are equipped with a “state of the art” digital passive eye tracking system. It records only measurements taken under perfect fixation conditions. Rejected recordings will be automatically repeated. The patient's eye is displayed at any time during the examination for visual control by the examiner. Fixation control using the Heijl-Krakau method is also integrated.

Short Examination Time
Due to the fact that the units can take former testing protocols of the same patient into consideration, the examination time can be reduced tremendously. Already known defects will be screened and not necessarily checked through a complete testing routine again. With the automated adaptation to the patient response the system is able to optimize all time parameters with full result credibility.

Modern Data Handling
The Perimat comes with an integrated modern PC that communicates with all USB printers. All acquired data can be transmitted to a network and sent in many different formats depending on individual requirements. The design of the Perimat is more compact due to the integrated PC. This saves valuable space and reduces cables. The Peristat can be connected individually to a standard PC or Laptop making configuration economical and flexible.

Pupil Measurement
It is possible to measure the pupil diameter at any time even before, after or during the examination.

LED–Technology / Blue on Yellow Test
Both systems integrate the LED background illumination and provide a standardized blue on yellow test routine, using Goldmann V fixation spot size. Kinetic test mode: Stimulus with adjustable size, intensity and speed is moving from the periphery to the center of measurement bowl.

Kinetic and Static Driving Test (Perimat)
The integrated standard driving test can be modified according to every individual demands, in kinetic or static routine. (Peristat static only)
