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 Glaucoma Staging Program (GSP) is useful in early detection of Glaucoma.
The GSP software grades examination findings into visual field classes (normal, glaucomatous, artifactual and neuro) based solely on their appearance. In addition, risk classes (normal, suspect, pre-perimetric, early stage, moderate and severe) are also assigned to findings of different severities that are classified as normal or glaucomatous. The examination results are presented in easy to understand green, yellow and red bar charts.
The striking novelty of the GSP is its ability to detect subtle changes in the visual field associated with early stage Glaucoma. Findings in the suspect and pre-perimetric risk classes contain reductions in the visual field that cannot be readily seen by the examiner. They usually remain undetected by the standard perimetric indices.
The Glaucoma Likelihood Index (GLI) summarizes the results of the GSP classification into a single parameter, presenting a value of between 0 (normal) and 5 (advanced Glaucoma).
The Glaucoma Staging Program (GSP) is available for the OCULUS Twinfield® 2, Centerfield® 2, Smartfield and Easyfield® perimeters. This upgrade is available for the existing units.
