 Purpose:To identify factors involved in summation of binocular visual field in glaucoma. Patients and Method:A total of 32glaucoma patients entered the study. They had corrected visual acuity of 20/20 or over and had defects within 10 degrees of central visual field. Humphrey 10-2 full-threshold program was used to measure the monocular and binocular visual field. Findings:Binocular visual field showed good correlation with the threshold in the better eye for each point. Summation of binocular visual field developed when the threshold in the worse eye was greater than 21dB for each point. Summation developed when the difference in threshold was greater than 4dB between each pair of eyes. Conclusion:Summation may develop in binocular visual field in glaucoma under certain conditions.
