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/ m2 was 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.
