“…SAP employs differential light stimulus, which is nonspecific for ganglion cell type, whereas FDT perimetry measures contrast sensitivity and targets magnocellular cells. 8,12,24 In conclusion, Humphrey Matrix is a quicker test than SAP-SITA. Visual field indices and the number of depressed points on PDP of the two perimetries are only moderately correlated.…”

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.

“…SAP is still considered the gold standard in glaucomatous visual field assessment; however, longstanding experience with SAP has uncovered many limitations, some of which are related to the testing method, while others relate to the subjective, patientdependent nature of the testing process [20,21]. Certain improvements in SAP, such as short- IOP intraocular pressure, C/D cup to disc ratio, BCVA best corrected visual acuity wavelength automated perimetry (SWAP), have demonstrated a significant advantage as far as its ability to detect field defects earlier than SAP, but fall short as far as follow-up [22].…”

The distribution of visual field defects per quadrant in standard automated perimetry as compared to frequency doubling technology perimetry

To test the ability of frequency doubling technology (FDT) perimetry to reveal defects in the same field quadrants as detected by standard automated perimetry (SAP). Ninety-two eyes with open-angle glaucoma and documented visual field defects by threshold SAP (Octopus Dynamic strategy) also underwent threshold FDT testing after successfully passing the FDT screening test. All eyes revealed varying stages of SAP defects while only 80 revealed FDT damage: 31:21 eyes in the early field loss stage, 36:35 in the moderate field loss stage, and 25:24 in the severe field loss stage in SAP versus FDT, respectively. SAP was able to detect abnormalities in 74 and 79% of the superotemporal, and inferotemporal quadrants, respectively, while the corresponding FDT figures were 70 and 69% for the same quadrants (P < 0.05 each). With regards to the nasal hemifield, SAP detected defects in 73 and 81% of the superonasal and inferonasal quadrants, respectively, compared to 69 and 66% for FDT (P < 0.001 each). The test duration per individual eye was significantly shorter with FDT than with SAP (P < 0.05). As well as the already established lower sensitivity of FDT compared to SAP, this study also demonstrated the significantly poorer ability of FDT in detecting the same field quadrant defects, especially in the early stages of glaucomatous damage.
