Effectiveness of measuring the central field with the Berkeley field test

Abstract

The BCFT test was as good as the Amsler grid test at detecting the presence of maculopathy.

Assessment of Visual Function and Performance in Paralympic Judo for Athletes with Vision Impairment

“…The Berkeley Central Visual Field Test 25 was used to estimate the integrity of the central visual field (equipment for automated perimetry was not available at competition venues). The same 27-in Apple monitor was placed 40 cm from the participant to test the central 10° (radius).…”

“…Participants were instructed to fixate toward the intersection of two diagonal lines throughout the test and to respond by pressing the spacebar on a keyboard whenever they saw a stimulus (a black dot with a size of 0.4°of visual angle) presented in their periphery. In total, 50 stimuli appeared within a 10°radius along 1 of 10 meridians (25,65,115,155,195,225,255,285,315, and 345 °) at each of 5 eccentricities (1, 3, 5, 7, and 9 °). Each stimulus had a lifetime of 250 milliseconds, and interstimulus times varied randomly between 900 and 1300 milliseconds.…”
