Clinical experience with the Fieldmaster perimeter.

Perimetry performed on a Fieldmaster Model 200 on a consecutive series of 167 patients in a clinical practice setting demonstrated that Fieldmaster testing elicited 95% of defects found on Goldmann kinetic perimetry with very few false-positive or false-negative results; relatively unskilled personnel were able to conduct Fieldmaster testing well; and as our personnel and patients became familiar with the test, the rate of incomplete examinations declined to less than 2%.
