“…Leeprachanon et al evaluated the agreement between the two tests with the GHT and PSD criteria in patients with early to moderate visual field loss and found a substantial agreement between FDT-Matrix 24-2 and SAP with SITA standard 24-2 (83% agreement, κ=0.66 for GHT criteria and 86% agreement, κ=0.70 for PSD criteria). 21 The location of defects within 12 hemifield clusters found with FDT agreed moderately well with those detected with SAP (kappa=0.48). Sakata et al 22 used the same criteria as in our study for definition of abnormal visual field and reported a moderate agreement between the two perimetric methods similar to our finding (κ=0.49).…”

“…In a study by Leeprachanon et al, MD and PSD indices of SAP with 24-2 SITA standard algorithm and FDT Humphrey Matrix 24-2 full threshold tests showed significant correlations in patients with glaucoma (r=0.75 and r=0.80, respectively), but not in the normal group. In the study by Zarkovic et al, 21 Matrix. 23 Different correlations among previous studies can be explained by the characteristics of the patient population with variable visual defects ranging from early to severe, patient age and number of the studied subjects.…”

SummaryPurpose: To compare the results of Humphrey Matrix 30-2 full threshold test and standard automated perimetry (SAP) using the Swedish Interactive Threshold Algorithm (30-2 SITA standard strategy). Material and Method: Test duration, mean deviation (MD), pattern standard deviation (PSD), number of depressed points on pattern deviation plot (PDP) at level of p<0.05 and p<0.01 were compared using the Wilcoxon signed-rank test. The correlations between MD, PSD and the number of depressed points were analyzed using Spearman's rank correlation coefficient. Kappa (κ) statistic was used to determine the strength of agreement between Matrix and SAP-SITA tests. Results: PSD was higher in Matrix perimetry and the number of depressed points at level of p<0.05 was significantly higher in SAP-SITA test. MD (r=0.48), PSD (r=0.58) and the number of points depressed on PDP at the level of <0.05 and <0.01 (r=0.48 and r=0.47, respectively) showed moderate correlations between the two tests (p<0.001). The agreement between SAP and Matrix perimetry was found to be moderate (κ=0.44, p<0.001). ÖzetAmaç: Humphrey Matriks 30-2 tam eflik testi sonuçlar› ile ‹sveç interaktif eflik algoritmas›n› (30-2 SITA standart stratejisi) kullananan standart otomatize perimetri (SAP) sonuçlar›n› karfl›laflt›rmak. Gereç ve Yöntem: Test süresi, ortalama deviasyon (MD), patern standart deviasyon (PSD) ile patern deviasyon haritas›nda p<0,05 ve p<0,01 düzeyinde bask›lanm›fl nokta say›lar› Wilcoxon signed rank testi ile karfl›laflt›r›ld›. ‹ki testteki MD, PSD ve bask›lanm›fl nokta say›lar› aras›ndaki korelasyon Spearman korelasyon katsay›s› kullan›larak analiz edildi. Matriks ve SAP SITA testleri aras›ndaki uyumun de¤erlendirilmesinde kappa (κ) istatisti¤i kullan›ld›. Sonuçlar: PSD'nin matriks perimetride, p<0,05 seviyesinde bask›lanm›fl nokta say›s›n›n ise SAP-SITA testinde istatistiksel aç›dan anlaml› oranda yüksek oldu¤u saptand›. ‹ki test aras›nda MD (r=0,48), PSD (r=0,58) ve Patern deviasyon haritas›nda p<0,05 ve p<0,01 düzeyinde bask›lanm›fl noktalar›n say›s› (r=0,48 and r=0,47, s›ras›yla) aras›nda orta derecede korelasyon oldu¤u görüldü (p<0,001). SAP ve Matriks perimetri aras›ndaki uyumun orta düzeyde oldu¤u saptand› (κ=0,44, p<0,001). Tart›flma: ‹ki perimetrideki görme alan› indeksleri ve patern deviasyon haritas›ndaki bask›lanm›fl noktalar›n say›s› yaln›zca orta düzeyde korelasyon göstermektedir. Bu nedenle Matriks perimetri ve SAP'da ki global indeksler ve test noktalar› aras›nda do¤rudan bir karfl›laflt›rma yap›lmamal›d›r.

Aims: To compare the Humphrey Matrix Perimeter (HMP) with the Humphrey Field Analyser (HFA) in visual-field examinations of patients with glaucoma or suspected glaucoma. Methods: One hundred and forty-nine patients with suspected glaucoma or glaucoma were recruited. All patients underwent visual-field examinations with the Swedish Interactive Threshold Algorithm standard, the central 30-2 threshold test with the HFA, and the frequency doubling technique 30-2 threshold test with the HMP. The examination times, mean deviations (MDs) and pattern standard deviations (PSDs) of both perimeters were compared in all patients and according to the patient’s diagnosis or the severity of their visual-field defects (VFDs). The paired 2-tailed t test and Pearson’s correlation coefficients were used for statistical analyses. Results: Overall, the examination times were significantly shorter with the HMP than with the HFA. There was a positive correlation between the HFA and HMP measurements of MD and PSD. In patients with suspected glaucoma, the PSDs measured with the HMP were significantly higher than those measured with the HFA. In patients with mild VFDs (MD >–4.0 dB), PSDs measured with the HMP were significantly higher than those measured with the HFA. In patients with severe VFDs (MD <–12.0 dB), MDs measured with the HMP were significantly higher than those measured with the HFA, whereas PSDs measured with the HMP were significantly lower than those measured with the HFA. Conclusions: The HMP is more time efficient than the HFA in visual-field examinations. The HMP tends to overestimate mild VFDs and underestimate severe VFDs.
