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 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 Examination Programs
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.
The OCULUS Test Point Grid
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.
