Come and see The TrueField Analyzer (TFA) at this year’s AAO – booth #2619.
AAO Booth 2619
See the new TFA device in operation with updated test protocols and refined operator software.
If you have any interest in visual fields, then the TrueField Analyzer is the perimeter you need to see!

| 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. |
