“…The NEI VFQ-25 had been used in previous clinical studies (16) (18). However, despite these limitations, the questionnaire was found superior to other tools in assessing vision related quality of life (19) and it was the visual functioning and socioemotional traits that came out as most relevant in this survey.…”

“…Other investigators convincingly demonstrated by using modern psychometric techniques that the original tool should be adapted and revalidated. 41,56 The TSS-IOP pops up as the highest quality instrument to assess side effects across different topical treatments, 48,49 yet might be improved as well using Rasch-analysis. If interested in assessing adherence with eye drop treatment, both the adherence questionnaire of Schwartz et al and the EDSQ should be improved, given that both intend to predict nonadherence, but that the discrimination between adherent and nonadherent patients remains difficult.…”

The aim of this review was to summarize literature in view of patient-reported outcome (PRO) instruments for glaucoma and provide guidance on how outcomes are best assessed based on evidence about their content and validity. A systematic literature review was performed on papers describing the developmental process and/or psychometric properties of glaucoma or vision-specific PRO-instruments. Each of them was assessed on their adherence to a framework of quality criteria. Fifty-three articles were identified addressing 27 PRO-instruments. In all, 18 PRO's were developed for glaucoma and 9 for diverse ophthalmologic conditions. Seven instruments addressed functional status, 11 instruments quality of life and 9 instruments disease and treatment-related factors. Most of the instruments demonstrated only partially adherence to predefined quality standards. The tools for assessing functional status were of poor quality, while the Glaucoma Quality of Life Questionnaire and the Vision Quality of Life Index were well-developed QoL measures, yet only validated using classical techniques. The Rasch-scaled QoL-tools, IVI and VCM1 need to improve their item-content for glaucoma patients. The questionnaires to measure adherence should improve their validity and the Treatment Satisfaction Survey for Intra Ocular Pressure pops out as the highest quality tool for measuring topical treatment side effects. This review revealed that most PRO-instruments demonstrated poor developmental quality, more specifically a lack of conceptual framework and item generation strategies not involving the patients' perspective. Psychometric characteristics were mostly tested using classical validation techniques.

“…Despite being one of the most widely used of the visual function instruments, even the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) is still not applicable to all patient subsets. 21 In summary, this study has demonstrated that surgical correction of brow ptosis results in a measurable increase in health-related QoL. It has also shown that selfreported preoperative functional impairment is the only outcome measure significantly (and strongly) associated with postoperative increase in functional status, and that visual fields are the best available preoperative objective measure for estimating the expected extent of such improvement.…”

The Psychometric Validity of the NEI VFQ-25 for Use in a Low-Vision Population

Abstract: The native NEI VFQ-25 is a better performing instrument when split into visual functioning and socioemotional scales. These scales possess valid parameters for assessment of the impact of low vision in this population.
