M700 Automated Perimeter

High Precision
The concentric test point density, which increases towards the fovea, facilitates accurate determination of field loss, particularly for arcuate and small macula defects. In the standard Central 30 degree field, 100 test points are used with a macula region point density of typically 3 degrees.

Fast
A new fast threshold test strategy is now available. With the use of advanced predictive logic algorithms, a 30 degree field can be completed in as little as 3 minutes per eye. Screening examinations require only 1.5 minutes per eye. Defects are automatically confirmed and qualified.

Full Field Capabilities
With a test capability extending to 80 degrees, the M700 provides a complete diagnosis of a patient’s visual field, allowing peripheral defects that are not associated with the central field to be explored. With the DV2000 Software package the practitioner is now able to store perimetry, topography and digital imaging results in a format that is more easily accessible. This negates the need for multiple patient entry and improves markedly the efficiency of the practice.

Full integration with the major practice management databases is available, and the access of data over a netwrok means that you are not confined to viewing information from the PC that is running the equipment.

Familiar User Interface
The explorer style interface allows easy navigation and review of patient results and direct access to all functionality at all times. Swap from reviewing test results or editing patient details with a single mouse click. Multiple image maps can be displayed with a wide variety of options and map types. The profile display provides an interactive view of the image data at any cross-section.

The multimedia capabilities (sound card required) of the M700 provide a wide range of audible warning tones for specific events (eg fixation loss, end of test) that may occur during an examination. Several M700 units can operate on a network sharing a single database.

Unique Test Facilities
Binocular Driving Test: Meeting worldwide standards to check a drivers visual field, this new test covers 160 degrees of patient’s binocular field.

Flick Test: Tests with a flickering stimulus provide improved sensitivity and earlier detection of field loss over normal static tests. The M700 offers this facility with a special test strategy which requires the patient to respond to the presence of flicker in the stimulus.

Diplopia Test: The M700 provides a unique diplopia test where targets are presented in a sequence requiring a progressive change in the direction of gaze by the patient. Indication of a double image results in automatic detailed examination of that area of gaze.

Custom Fields
Create a new test region quickly and easily. Use the mouse to select a reqion and you are ready to commence testing.

Defect Verification
Using the mouse you can retest completed points or add new test locations at the periphery of a field while the test is still running, enabling any suspect field defects to be verified and fully explored without undertaking a new test.

Sophisticated Testing
The new spatially adaptive test initially utilises a sparse field. If the software finds an area of concern additional points will be tested, this offers a new, faster method of defining, a large defect. For all tests patient reaction time is continuously monitored and the speed of the stimulus presentation is adjusted accordingly.
