TrueField
Rapid • Bilateral • Objective • Pupil Perimetry
The TrueField Analyzer (TFA) is being launched at this year’s AAO – come and see the device at booth #2619 in the Exhibition Halls.
AAO Booth 2619
Available initially on limited release the device heralds a new era in vision testing. In a world’s first development the TFA offers objective non-contact visual field testing which has the potential to revolutionize the staging and management of a range of vision disorders.
The TFA offers patients the comfort and ease of a fast and simple test, and brings clinicians an objective test that eliminates the subjective methods of traditional tests and the complications associated with them.
If you have any interest in visual fields, then the TrueField Analyzer is the perimeter you need to see!

AAO Paper: PA059
Time: Monday Oct 26, at 3:21 PM
Location: Room NORTH 133
ABSTRACT: Purpose: To compare 8 TrueField Analyzer methods. Methods: Two blocks of trials contained 41 normal and 47 glaucoma subjects, and 40 normals and 39 patients. We compared 4 or 6 min stimulus durations and 2 methods of balancing luminances in an attempt to produce higher median reliability across the field as measured by t-statics for each field region. The dichoptic stimuli extended to 30 deg eccentricity. Maximum luminance and stimulus presentation rate were also varied. All subjects were also examined with Matrix and HFA perimetry, and Stratus OCT. Results: The 44 region/eye, 1/s stimuli, gave areas under ROC plots of: moderate + severe fields of 0.86 ± 0.04, severe 0.98 ± 0.01. Median t-statistics improved by 20% to 3.28 ± 0.45. Conclusion: High diagnostic accuracy and median t-stats were obtained from this improved binocular method.
