A group of 20 subjects had fixation disparity curves plotted at three times in one day, and also had distance and near associated and dissociated heterophorias recorded. These measures were made in the morning, at midday and in the evening. Statistical analysis showed that there were no time‐of‐day effects on fixation disparity of heterophoria.
