Flicker-defined form perimetry in glaucoma patients

Purpose To assess the potential of flicker-defined form (FDF) perimetry to detect functional loss in patient groups with beginning glaucoma, and to evaluate the dynamic range of the FDF stimulus in individual patients and at individual test positions. Methods FDF perimetry and standard automated per...

Description
Summary:Purpose To assess the potential of flicker-defined form (FDF) perimetry to detect functional loss in patient groups with beginning glaucoma, and to evaluate the dynamic range of the FDF stimulus in individual patients and at individual test positions. Methods FDF perimetry and standard automated perimetry (SAP) were performed at identical test locations (adapted G1 protocol) in 60 healthy subjects and 111 glaucoma patients. All patients showed glaucomatous optic disc appearance. Grouping within the glaucoma cohort was based on SAP-performance: 33 “preperimetric” open-angle glaucoma (OAG) patients, 28 “borderline” OAG (focal defects and SAP-mean defect (MD)
