The Frontloading Fields Study

The Frontloading Fields Study assessed the viability, in terms of time taken for testing and repeatability, of frontloading (performing multiple perimetric examinations) in a single clinic visit.

Authors Dr Jack Phu and Professor Michael Kalloniatis have developed the tool below to calculate the follow-up visit at which 95% of cases are detected, the predicted time to detect 95% of cases and the mean deviation at follow-up.
