The Frontloading Approach to Meet Guideline-Recommended Visual Field Testing for Glaucoma: Time and Cost.
Purpose: To measure the time and clinical resources taken to obtain 6 reliable visual field (VF) tests for glaucoma in a glaucoma clinic.
Design: Longitudinal, prospective study in a glaucoma clinic.
Subjects: Ten thousand and ten SITA-Faster VF tests of 535 clinical subjects.
Methods: The cumulative number of VF tests with false-positive rates ≤15% for each eye of each subject was counted over time, and from there, the time to achieve 6 VF tests was determined and compared under frontloaded (2 VFs per eye per visit) and non-frontloaded (first VF within the frontloaded set) conditions. Costs to attain 6 VF tests were modeled.
Main outcome measures: Visual field counts and costs for attainment.
Results: Eight thousand nine hundred thirty-one of the 10 010 VF results had a false-positive rate of ≤15%. Approximately 90% of subjects had early or moderate open-angle glaucoma. When using the frontloading protocol, it took an average of 1.4 years to attain 6 reliable VFs for right and left eyes, respectively. For the non-frontloaded protocol, the average times were 2.6 and 2.5 years for the right and left eyes, respectively; 82.5% of right eyes and 85.4% of left eyes achieved 6 reliable VFs within 2 years when frontloaded, but the proportion was only 15.8% and 18.8% when non-frontloaded for right and left eyes, respectively. There was a significantly lower cost for obtaining 6 reliable VFs with frontloading than non-frontloading, due to fewer office visits.
Conclusions: A frontloading approach and SITA-Faster paradigm led to patients attaining 6 reliable VFs over 14 months sooner than non-frontloaded, with >84% receiving the recommended number of 6 tests in the first 2 years. The frontloading approach overall leads to savings in time and cost in comparison to non-frontloading for achieving 6 reliable VFs and thus potentially provides an avenue for earlier detection of glaucomatous change.
