“…This is consistent with the work of Massof 18,19 and Massof and Ahmadian, 20 who showed that a subset of NEI VFQ functioning items taps the same construct as other visual functioning instruments; that is, the Visual Functioning 14 (VF-14), the Visual Activities Questionnaire, and the Activities of Daily Vision Scale (ADVS). Many other studies 38,39,55 applied Rasch analysis to the NEI VFQ, but simply to derive Rasch estimates of total and subscale scores. No attempt was made to assess the validity of the NEI VFQ within the Rasch model.…”

“…This applies to the NEI VFQ-39 and the NEI VFQ-25; for the sake of clarity, regardless of the number of items in the revised scales, the revised scales will be identified by their origin as [scale name] 39 or [scale name] 25 . 39 The first revision of the NEI VFQ-39 visual functioning scale was the long-form visual functioning scale 39 (LFVFS 39 ).

“…Neither had misfitting items, and both were unidimensional by PCA, with firstcontrast magnitudes of 1.5 eigenvalue units and 1.2 eigenvalue units, respectively. 39 The first revision of the NEI VFQ-39 socioemotional scale was the long-form socioemotional scale 39 (LFSES 39 ).

“…Other studies evaluating NEI VFQ translations in a Rasch model did not fully evaluate its overall and subscale validity, including unidimensionality. 38,39 Assessment of the performance of an entire instrument does not confer validity to its subscales. Subscales have the same requirements for validity (unidimensionality, precision, item fit to the construct) as the overall instrument; therefore, it subscales must be individually tested.…”

“…36,37 Studies agree that the domains affected greater in glaucoma subjects are mainly general health, general vision, mental health, expectations, driving and near activities both for NEI-VFQ and NEI-VFQ 25 questionnaires. 2,24,33,[38][39] Both tools are shown to be capable of distinguishing glaucoma from normal control subjects, with the scores of glaucoma patients being significantly poorer on most subscales. In addition, lower scores correlated well with visual field loss of glaucoma patients in the eye with the least visual field deterioration.…”

Association Between Progressive Retinal Nerve Fiber Layer Loss and Longitudinal Change in Quality of Life in Glaucoma

IMPORTANCE Evaluation of structural optic nerve damage is a fundamental part of diagnosis and management of glaucoma. However, the relationship between structural measurements and disability associated with the disease is not well characterized. Quantification of this relationship may help validate structural measurements as markers directly relevant to quality of life.OBJECTIVE To evaluate the relationship between rates of retinal nerve fiber layer (RNFL) loss and longitudinal changes in quality of life in glaucoma. DESIGN, SETTING, AND PARTICIPANTS Observational cohort study including 260 eyes of 130 patients with glaucoma followed up for a mean (SD) of 3.5 (0.7) years. All patients had repeatable visual field defects on standard automated perimetry (SAP) at baseline. The 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was performed annually, and spectral-domain optical coherence tomography and SAP were performed at 6-month intervals. A joint model was used to investigate the association between change in NEI VFQ-25 Rasch-calibrated scores and change in RNFL thickness, adjusting for confounding socioeconomic and clinical variables. MAIN OUTCOMES AND MEASURESAssociation between change in binocular RNFL thickness (RNFL thickness in the better eye at each point) and change in NEI VFQ-25 scores.RESULTS Progressive binocular RNFL thickness loss was associated with worsening of NEI VFQ-25 scores over time. In a multivariable model adjusting for baseline disease severity and the rate of change in binocular SAP sensitivity, each 1-μm-per-year loss of RNFL thickness was associated with a decrease of 1.3 units (95% CI, 1.02-1.56) per year in NEI VFQ-25 scores (P < .001). After adjusting for the contribution from SAP, 26% (95% CI, 12%-39%) of the variability of change in NEI VFQ-25 scores was associated uniquely with change in binocular RNFL thickness. The P value remained less than .001 after adjusting for potential confounding factors.CONCLUSIONS AND RELEVANCE Progressive binocular RNFL thickness loss was associated with longitudinal loss in quality of life, even after adjustment for progressive visual field loss. These findings suggest that rates of binocular RNFL change are valid markers for the degree of neural loss in glaucoma with significant relationship to glaucoma-associated disability.
