To investigate the agreement of Humphrey Field Analyzer (HFA) and Humphrey Matrix perimeter (HMP).
Fifty six eyes of 56 glaucoma and suspected glaucoma patients were included. These eyes had two or more reliable HFA results. Screening N30–1 program (10degree spot size) and threshold 24–2 program (5 degree spot size) of HMP were applied for all patients. Test results were evaluated at each quadrant as normal, suspected abnormal and abnormal. The kappa coefficient of HFA results and HMP results of the following three were calculated. (a) N30–1, (b) total deviation of threshold 24–2, and (c) pattern deviation of threshold 24–2.
Mean age of patients was 56.9+/–10.8 year old(range, 21–76). Mean deviation (MD) of HFA was –2.41+/–2.4dB (range, 2.27∼ –9.02dB). MD and Pattern standard deviation of HMP was –6.96+/–4.2dB (range, –0.84∼–19.6dB), and 4.73+/–1.91 (range, 1.99∼9.67dB), respectively. While HFA showed 51 abnormal quadrants out of 224 quadrants, the number of abnormal HMP quadrants for (a), (b), (c) were 46, 123 and 81, respectively. The kappa coefficient for (a), (b), (c) was 0.468, 0.247 and 0.390, respectively.
Large spot or pattern deviation of small spot of HMP had good agreement with HFA. Total deviation of small spot had poor agreement with HFA due to higher sensitivity of HMP.
