Comparison of Glaucomatous Visual Field Defects Using Standard Full Threshold and Swedish Interactive Threshold Algorithms

Abstract

VISUAL FIELD ANALYSIS and optic nerve visualization are critical indicators used in the diagnosis and management of glaucoma.¹ Full threshold (FT) white-on-white automated static perimetry^2,3 is the gold standard for the diagnosis, grading, and detection of progression of glaucomatous visual field defects in standard practice and in glaucoma clinical trials research.^4-9 However, the standard FT method for measuring the visual field is time-consuming for patients and is subject to fatigue effect, which has been shown to result in poorer results.^10-12 This effect is more pronounced in patients with glaucoma.^11,13
