- Abstract
Purpose: We assessed vision-related quality of life (VR-QOL) in glaucoma patients and examined the relationship between VR-QOL and indices of visual function and subjective symptoms., Patients and Methods: Four hundred seventy-two glaucoma patients completed a questionnaire concerning VR-QOL and subjective symptoms of glaucoma. VR-QOL was based on 5 subscales selected from the National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25), whereas subjective symptoms were examined using original questions that we prepared. The following were selected as visual function indices: corrected visual acuity measured with a distance visual acuity chart, mean deviation scores measured with a static perimeter, and 4 threshold levels in the innermost center of a visual field (4 pericentral test points). Disease staging was conducted according to the Aulhorn classification system. Correlations of visual function with VR-QOL were evaluated using the Spearman test., Results: Correlations were observed in almost all subscales of the NEI VFQ-25, including correlations with corrected vision, disease stage, mean deviation score, and minimum threshold values of the 4-point pericentral test on the temporal side (P<0.0001). Visual function indices affecting driving differed between daytime and night driving (P<0.0001). NEI VFQ-25 subscales were correlated with subjective symptoms felt by the patients while driving (P<0.0001)., Conclusions: Minimum threshold values of the 4 pericentral test points on the temporal side are useful for the assessment of VR-QOL. Minimum threshold values of the 4 pericentral test points on the temporal side are useful for assessing visual field abnormalities that are associated with decreased VR-QOL.
