Comparison of Methods to Detect and Measure Glaucomatous Visual Field Progression.

Purpose: To compare methods to assess visual field (VF) progression in glaucoma.

Methods: 4,950 VFs of 253 primary open angle-glaucoma patients were evaluated for progression with the following methods: clinical evaluation, guided progression analysis (GPA), mean deviation (MD), and visual field index (VFI) rates, Advanced Glaucoma Intervention Study (AGIS) and Collaborative Initial Glaucoma Treatment Study (CIGTS) scores, pointwise linear regression (PLR), permutation of PLR (PoPLR), and glaucoma rate index (GRI). A separate simulated series of longitudinal VFs was assessed with all methods except for GPA and clinical evaluation.

A Method to Measure the Rate of Glaucomatous Visual Field Change.

Purpose: To develop a method to measure the rate of glaucomatous visual field (VF) deterioration and to identify fast progressors.

Methods: Retrospective, longitudinal, observational study of 8486 eyes of 4610 glaucomatous patients with ≥6 VFs and ≥3 years of follow-up. A Glaucoma Rate Index (GRI) was calculated.
