Summary

This study aims to compare two types of visual field test; retinal sensitivity values obtained with the reference standard Swedish Interactive Thresholding Algorithm (SITA) of the standard visual field test and with a newly developed test algorithm. The new test is a visual field test presented on a flat-panel monitor and has two modes: differential light sensitivity (DLS; equivalent to the standard visual field test) and the Moorfields Motion Displacement Test (MMDT). DLS sensitivity and DLS measurement variability will be determined and compared between the SITA algorithm of the standard visual field test and the new visual field test on the flat-panel monitor. The measurement variability of the MMDT will be quantified.

The long-term goal is to reduce test variability below that observed in SITA by 20%, whilst producing comparable measurements (contrast threshold values) for comparable test duration.
