PRÉCIS: The diagnostic performance for detecting early glaucoma of a supra-threshold and a threshold visual field tests are compared. Their performance was found to be equivalent with the supra-threshold test being faster.
PURPOSE: To compare the diagnostic accuracy of a supra-threshold and a threshold visual field test in detecting early glaucoma using optical coherence tomography (OCT) as the reference standard.
METHODS: Data from 54 early/suspect glaucoma patients and 37 controls underwent a Humphrey Visual field Analyzer (HFA) SITA standard 24-2 threshold test, a Henson 9000 Smart Supra test (SS) supra-threshold test and Topcon Triton OCT scan: Smart Track 3D Wide (H) (12 × 9). OCT data were classified by 3 experts as either no glaucoma (n=42), suspect (n=6), or glaucoma (n=43). Overall and Selective global indices and receiver operating characteristics (ROC) curve analysis were used to compare visual field outcomes with OCT classifications.
RESULTS: SS was significantly faster than SITA standard (3.9 vs. 6 min). Sixty-one percent of the glaucoma sample and 81% of controls showed substantial agreement between OCT and visual field testing using the most sensitive criteria (Henson-N-miss SS, stage 2 and 3, >0 misses; HFA VFI <99%). The area under the ROC curve showed good discrimination for all global indices. The 24-2 global indices MD, PSD, and VFI ranged from 86% to 89%, whereas those for the SS test ranged from 84% to 88%. Partial area under the ROC curve (80%-100% specificity) showed a fall for all global indices. HFA MD, PSD and VFI range (61%-73%), SS test range (71%-78%).
CONCLUSIONS: The SS supra-threshold test was faster and had equivalent diagnostic accuracy to the SITA standard 24-2 threshold test in early/suspect glaucoma.
