To determine how glaucoma and glaucoma suspect patients' rating of their vision correlates with Esterman binocular visual field testing and other visual function tests.


One hundred ninety-one glaucoma patients and 46 glaucoma suspect patients underwent binocular visual field testing and evaluated their vision using the linear rating scale and time-tradeoff utility tests, the National Eye Institute Visual Functional Questionnaire (NEI VFQ-25), and the Short Form 36 (SF-36) quality-of-life instruments.


The mean Esterman score was 88.2 +/- 17.4 for the glaucoma subjects and 95.2 + 6.9 for glaucoma suspect subjects (maximum score 100). On a scale from 0 (blind) to 100 (ideal), the mean rating of vision for glaucoma patients and glaucoma suspect patients was 74.8 +/- 17.3 and 78.9 +/- 18.5, respectively. The Esterman test correlated moderately with the overall NEI VFQ-25 score (partial correlation coefficient (PCC) = 0.32, P = 0.001), but only weakly with the linear rating scale (PCC = 0.17, P = 0.02), and the time-tradeoff (PCC = 0.14, P = 0.06).


Utility values that glaucoma and glaucoma suspect patients assign to their vision do not correlate well with Esterman results. A challenge for the future is the design of clinical tests of vision that better correlate with patient perceptions.
