Thanks to its ergonomic design, user-friendly program navigation and ease of operation, the Centerfield® 2 Perimeter has proven itself to be an invaluable instrument in the Occupational Health area. The unit performs static perimetry up to 70° eccentricity. It also meets the requirements of the German Ophthalmological Society’s (DOG) Road Traffic Commission for conducting visual field testing in accordance with the regulations for the issuance of driver’s licenses and the Guidelines G25 and G41 issued by the German Institute for Occupational Health and Safety.

The self-contained design and light-shielded viewer allow examinations to be conducted in normally lit rooms. Its robustness and light weight make the Centerfield® 2 perimeter the ideal unit for portable use, which is often a necessity in the Occupational Health area.
The results of the perimetric measurements are summarized in a clearly structured printout. Areas of abnormality can be quickly recognized and re-examination of these areas independent of the test point grid gives the diagnostic analysis even greater reliability.

The Centerfield® 2 perimeter can be operated via the USB port of a notebook or PC. Together with the supplied device software, this modern solution allows you to fully utilize all of the benefits of today’s IT systems, especially the network connectivity. This guarantees both safe storage of examination data and quick access to that data when needed.

The recommended series of pre-defined test programs provided for Centerfield® 2 perimeter covers the examinations most frequently needed in practice. The “Driver’s License Regulations“ program permits occupational and company physicians to test the field of vision in accordance with applicable German regulations (FEV and amendments thereto) governing the issuance of driver’s licenses. The macula and glaucoma programs allow early detection of various retinal diseases.
Threshold related - suprathreshold strategies have proven to be time-saving and efficient examination methods. The Centerfield® 2 perimeter uses these strategies for all screening programs, including the Driver’s License eye exams. A variety of threshold testing strategies are available for measurement of the exact numeric values of the visual thresholds.
The patented projection method allows you to freely select test point grids on the Centerfield® 2. The central field of vision can be examined using functionally or orthogonally distributed test points. Grids such as the “FeV70” or “Esterman” are used for the periphery. This unlimited flexibility enables test grids to be modified if necessary.
