Improved Assessment of Visual Field Change

VA Office of Research and Development·observational·Posted Jan 20, 2010·Updated Mar 21, 2017

In Brief

An observational study evaluating Comparison of four visual field testing strategies for Glaucoma. Completed, enrolled 180 participants across 1 site.

Detailed Summary

Improved Assessment of Visual Field Change is a trial aimed at investigating mechanisms of visual field testing variability. The investigators have found using larger stimulus size substantially lowers short-term variability. In this study, the investigators will determine if larger stimuli detect visual field change at an earlier time. The investigators are also developing a statistical model that accounts for correlations of neighboring test locations.
