To investigate the correlation of binocular visual field (VF) with vision-specific quality of life in glaucoma patients.

Sixty patients who were diagnosed as open-angle glaucoma were recruited for the present study. The patients had at least moderate VF defect in 1 eye. VF testing was performed using the unilateral Humphrey Field Analyzer (HFA) and binocular Esterman VF test which was divided into 6 clusters: upper and lower center 10', upper and lower center 30', and upper and lower periphery. The 25-item National Eye Institute Visual Function Questionnaire (VFQ) was used to evaluate patients' vision-specific quality of life. We analyzed the correlation between the efficiency score of each cluster from binocular Esterman VF test, mean deviation of HFA, and the scores of VFQ (Spearman correlation).

The correlation between the composition score of VFQ and total score of binocular Esterman visual field test was significant. The highest correlation was observed in the lower periphery cluster (all p < 0.05). For general vision, the lower center 10' visual field was strongly correlated ( p = 0.011), and for driving, the upper peripheral visual field was the strongest correlated ( p = 0.038). The level of mean deviation in the worse eye showed significant correlation with composition score of questionnaire ( p = 0.008), otherwise the level of mean deviation in the better eye did not show any significant correlation ( p > 0.05).

Binocular Esterman VF test is an easy and effective way to evaluate the vision-specific quality of life in glaucoma patients.
