OCULUS Twinfield^® 2

Perimeter

The OCULUS Twinfield^® 2 provides you with the very best of our more than 50 years of experience in the perimetry area. This device measures the full field of vision using both automatic, static perimetry and automatic or manual kinetic examinations. The Twinfield^® 2 received the express recommendation of the German Ophthalmology Society (DOG) for expert assessment perimetry.

Glaucoma Staging Program (GSP)

The Glaucoma Staging Program (GSP) is based on pattern recognition and is dedicated to early detection of glaucoma.

The GSP software places 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 that are classified as normal or glaucomatous. The evaluation results are presented in intuitive green-yellow-red color coding.

The striking novelty of the GSP is its ability to detect subtle changes in the visual field associated with early stage glaucoma. Findings of suspect and pre-perimetric risk classes may contain reductions in the visual field that cannot be readily seen by the examiner. They usually remain undetected also by standard perimetric indices.

The Glaucoma Likelihood Index (GLI) summarizes the results of the GSP classification into a single parameter presenting a value between 0 (normal) and 5 (severe glaucoma).

The Glaucoma Staging Program (GSP) is available for OCULUS Twinfield^® 2, Centerfield^® 2 and Easyfield^® perimeters. This upgrade is available for the existing units.
