The Comparison of The Matrix Perimetry and Humphrey Standard Perimetry in Various Patients Group

ABSTRACT

PURPOSE: To study the correlation between the Humphrey standard automated perimetry (SAP) and the Humphrey Matrix Frequency Doubling Technology (FDT) perimetry and diagnostic usefulness of the Humphrey Matrix FDT perimetry. METHODS: This study included 170 eyes of 170 patients. The 170 eyes were classified into 50 normal eyes, 20 ocular hypertensive eyes, 50 glaucoma-suspect eyes and 50 glaucomatous eyes. All subjects were examined with the Humphrey Matrix perimetry and the Humphrey standard automated perimetry. We studied the correlations between mean deviation (MD) and pattern standard deviation(PSD) of the Humphrey SAP and those of the Humphrey Matrix perimetry, respectively, in each of the classified group. RESULTS: Overall, MD and PSD of the Humphrey SAP were significantly correlated with MD and PSD of the Humphrey Matrix perimetry, respectively. However, MD and PSD of the Humphrey Matrix perimetry were not showed a significant correlation in normal subjects (P>0.05). CONCLUSIONS: In this study, there were significant correlations between the MD and PSD of the SAP and those of the Humphrey Matrix perimetry in glaucoma, glaucoma-suspect and ocular hypertension. These finding suggests the Humphrey Matrix perimetry has performance characteristics similar to SAP and diagnostic value.
