Threshold Noiseless Trend (TNT) Progression Analysis

TNT provides a quantitative, statistical analysis of the visual field examinations conducted over time. For follow-up purposes the software uses all visual field results taken over the entire observation period and takes the patient's threshold values into account obtained on the 30-2, 30x24 or 24-2 patterns. TNT uses a specific filter to reduce the fluctuation range of the threshold values and to perform a consistent trend analysis. In conjunction with the fast SPARK strategy, the sensitivity of detecting progression in early stage glaucoma is greatly improved.

TNT creates a concise progression analysis report containing the most important parameters (MD increase, p-values, etc.).
TNT can differentiate between diffuse and focal progression based on the focality index (FI) value.
TNT applies multiple statistical criteria to establish possible progression.
TNT displays the prognosis of the expected visual field for a patient age-group selected by the examiner.
