Abstract. We evaluated the visual function in 36 eyes of advanced glaucoma using a low vision evaluator. All the eyes had decreased sensitivity in the central field. The corrected visual acuity was 0.5 or over in 29 eyes and 0.4 or less in 7 eyes. During examination with the low vision evaluator,a white background of 20cd/m2was presented to the eye. We used three stimuli from light-emitting diodes:red(644 nm),blue(470 nm)and green(525 nm). The results with blue stimuli showed a high correlation with findings by averaged 4 center points of total deviation by Humphrey Central 10-2 threshold test(r=0.72,p<0.001). The present device promises to be of value in the evaluation of visual function in advanced glaucoma.
