Background:

The Humphrey Field Analyser is a standard tool for visual field testing.
Evaluating new software for efficiency and accuracy is crucial for clinical practice.

Purpose of the Study:

To assess the efficacy of the Fastpac program on the Humphrey Field Analyser.
To compare the speed and accuracy of Fastpac with conventional methods.

Main Methods:

A substudy compared Fastpac and conventional full threshold 24-2 visual fields in 39 eyes.
A separate comparison evaluated standard and non-standard 80-point screening tests against the standard 24-2 full threshold test in 23 eyes.

Main Results:

Fastpac demonstrated 100% agreement with the standard full threshold test, completing tests 32%–39% faster.

In screening tests, the non-standard 80-point test showed higher sensitivity (1.0) than the standard (0.83) but was not faster.

Conclusions:

Fastpac software offers accurate visual field screening and threshold testing.
The Fastpac program significantly reduces testing time compared to standard algorithms, improving efficiency in visual field assessment.
