To evaluate the ability of Humphrey Matrix Frequency Doubling Perimetry (FDT) to detect homonymous defects found on Standard Automated Perimetry (SAP).
We studied 8 patients with homonymous defects: 3 with hemianopias and 5 with quadrantanopias. An involved quadrant was defined as at least 9 points of p < 0.5% in the pattern deviation of SAP, or the total deviation of FDT. Each quadrant was studied separately for each patient and compared to the corresponding quadrant on SAP.
Using our criteria, FDT Matrix provided a sensitivity of 77% and specificity of 100% in detecting homonymous visual field defects.
The newer FDT Matrix has the ability to detect homonymous field defects with acceptable sensitivity and specificity.
