Title: Deputy Head of the Glaucoma Service and Head of Clinical Services of National Healthcare Group Eye Institute, Tan Tock Seng Hospital (Singapore)

Topic Synopsis: This presentation provides a comprehensive overview of Humphrey Field Analyzer (HFA) interpretation and progression analysis in glaucoma management. It summarizes basic concepts of visual fields and perimetry testing, with particular focus on static automated perimetry with the HFA. An overview of various test algorithms and patterns is given. Interpretation of the HFA single field analysis is described through reliability indices, sensitivity and greyscale plots, deviation maps, the glaucoma hemifield test, and global indices such as mean deviation and the visual field index. Guided Progression Analysis, which provides both event-based and trend-based analyses, is also explained, with the help of clinical examples.
